6.7

---

(bugfix release; released on January 6th 2017)

• Make click.progressbar work with codecs.open files. See 637.
• Fix bug in bash completion with nested subcommands. See 639.
• Fix test runner not saving caller env correctly. See 644.
• Fix handling of SIGPIPE. See 626
• Deal with broken Windows environments such as Google App Engine's. See 711.

Flask 0.11.1 -> 0.12

0.12

---

Released on December 21st 2016, codename Punsch.

• the cli command now responds to --version.
• Mimetype guessing and ETag generation for file-like objects in send_file
  has been removed, as per issue 104. See pull request 1849.
• Mimetype guessing in send_file now fails loudly and doesn't fall back to
  application/octet-stream. See pull request 1988.
• Make flask.safe_join able to join multiple paths like os.path.join
  (pull request 1730).
• Revert a behavior change that made the dev server crash instead of returning
  a Internal Server Error (pull request 2006).
• Correctly invoke response handlers for both regular request dispatching as
  well as error handlers.
• Disable logger propagation by default for the app logger.
• Add support for range requests in send_file.
• app.test_client includes preset default environment, which can now be
  directly set, instead of per client.get.

0.11.2

---

Bugfix release, unreleased

• Fix crash when running under PyPy3, see pull request 1814.

Jinja2 2.8 -> 2.9.5

2.9.5

---

(bugfix release, released on January 28th 2017)

• Restored the original repr of the internal _GroupTuple because this
  caused issues with ansible and it was an unintended change. (654)
• Added back support for custom contexts that override the old resolve
  method since it was hard for people to spot that this could cause a
  regression.
• Correctly use the buffer for the else block of for loops. This caused
  invalid syntax errors to be caused on 2.x and completely wrong behavior
  on Python 3 (669)
• Resolve an issue where the {% extends %} tag could not be used with
  async environments. (668)
• Reduce memory footprint slightly by reducing our unicode database dump
  we use for identifier matching on Python 3 (666)
• Fixed autoescaping not working for macros in async compilation mode. (671)

2.9.4

---

(bugfix release, released on January 10th 2017)

• Solved some warnings for string literals. (646)
• Increment the bytecode cache version which was not done due to an
  oversight before.
• Corrected bad code generation and scoping for filtered loops. (649)
• Resolved an issue where top-level output silencing after known extend
  blocks could generate invalid code when blocks where contained in if
  statements. (651)
• Made the truncate.leeway default configurable to improve compatibility
  with older templates.

2.9.3

---

(bugfix release, released on January 8th 2017)

• Restored the use of blocks in macros to the extend that was possible
  before. On Python 3 it would render a generator repr instead of
  the block contents. (645)
• Set a consistent behavior for assigning of variables in inner scopes
  when the variable is also read from an outer scope. This now sets the
  intended behavior in all situations however it does not restore the
  old behavior where limited assignments to outer scopes was possible.
  For more information and a discussion see 641
• Resolved an issue where block scoped would not take advantage of the
  new scoping rules. In some more exotic cases a variable overriden in a
  local scope would not make it into a block.
• Change the code generation of the with statement to be in line with the
  new scoping rules. This resolves some unlikely bugs in edge cases. This
  also introduces a new internal With node that can be used by extensions.

2.9.2

---

(bugfix release, released on January 8th 2017)

• Fixed a regression that caused for loops to not be able to use the same
  variable for the target as well as source iterator. (640)
• Add support for a previously unknown behavior of macros. It used to be
  possible in some circumstances to explicitly provide a caller argument
  to macros. While badly buggy and unintended it turns out that this is a
  common case that gets copy pasted around. To not completely break backwards
  compatibility with the most common cases it's now possible to provide an
  explicit keyword argument for caller if it's given an explicit default.
  (642)

2.9.1

---

(bugfix release, released on January 7th 2017)

• Resolved a regression with call block scoping for macros. Nested caller
  blocks that used the same identifiers as outer macros could refer to the
  wrong variable incorrectly.

2.9

---

(codename Derivation, released on January 7th 2017)

• Change cache key definition in environment. This fixes a performance
  regression introduced in 2.8.
• Added support for generator_stop on supported Python versions
  (Python 3.5 and later)
• Corrected a long standing issue with operator precedence of math operations
  not being what was expected.
• Added support for Python 3.6 async iterators through a new async mode.
• Added policies for filter defaults and similar things.
• urlize now sets "rel noopener" by default.
• Support attribute fallback for old-style classes in 2.x.
• Support toplevel set statements in extend situations.
• Restored behavior of Cycler for Python 3 users.
• Subtraction now follows the same behavior as other operators on undefined
  values.
• map and friends will now give better error messages if you forgot to
  quote the parameter.
• Depend on MarkupSafe 0.23 or higher.
• Improved the truncate filter to support better truncation in case
  the string is barely truncated at all.
• Change the logic for macro autoescaping to be based on the runtime
  autoescaping information at call time instead of macro define time.
• Ported a modified version of the tojson filter from Flask to Jinja2
  and hooked it up with the new policy framework.
• Block sets are now marked safe by default.
• On Python 2 the asciification of ASCII strings can now be disabled with
  the compiler.ascii_str policy.
• Tests now no longer accept an arbitrary expression as first argument but
  a restricted one. This means that you can now properly use multiple
  tests in one expression without extra parentheses. In particular you can
  now write foo is divisibleby 2 or foo is divisibleby 3
  as you would expect.
• Greatly changed the scoping system to be more consistent with what template
  designers and developers expect. There is now no more magic difference
  between the different include and import constructs. Context is now always
  propagated the same way. The only remaining differences is the defaults
  for with context and without context.
• The with and autoescape tags are now built-in.
• Added the new select_autoescape function which helps configuring better
  autoescaping easier.

2.8.2

---

(bugfix release, unreleased)

• Fixed a runtime error in the sandbox when attributes of async generators
  were accessed.

2.8.1

---

(bugfix release, released on December 29th 2016)

• Fixed the for_qs flag for urlencode.
• Fixed regression when applying int to non-string values.
• SECURITY: if the sandbox mode is used format expressions are now sandboxed
  with the same rules as in Jinja. This solves various information leakage
  problems that can occur with format strings.

MarkupSafe 0.23 -> 1.0

1.0

---

• Fixed custom types not invoking __unicode__ when used
  with format().
• Added __version__ module attribute
• Improve unescape code to leave lone ampersands alone.

requests 2.10.0 -> 2.13.0

2.13.0

+++++++++++++++++++

Features

• Only load the idna library when we've determined we need it. This will
  save some memory for users.

Miscellaneous

• Updated bundled urllib3 to 1.20.
• Updated bundled idna to 2.2.

2.12.5

+++++++++++++++++++

Bugfixes

• Fixed an issue with JSON encoding detection, specifically detecting
  big-endian UTF-32 with BOM.

2.12.4

+++++++++++++++++++

Bugfixes

• Fixed regression from 2.12.2 where non-string types were rejected in the
  basic auth parameters. While support for this behaviour has been readded,
  the behaviour is deprecated and will be removed in the future.

2.12.3

+++++++++++++++++++

Bugfixes

• Fixed regression from v2.12.1 for URLs with schemes that begin with "http".
  These URLs have historically been processed as though they were HTTP-schemed
  URLs, and so have had parameters added. This was removed in v2.12.2 in an
  overzealous attempt to resolve problems with IDNA-encoding those URLs. This
  change was reverted: the other fixes for IDNA-encoding have been judged to
  be sufficient to return to the behaviour Requests had before v2.12.0.

2.12.2

+++++++++++++++++++

Bugfixes

• Fixed several issues with IDNA-encoding URLs that are technically invalid but
  which are widely accepted. Requests will now attempt to IDNA-encode a URL if
  it can but, if it fails, and the host contains only ASCII characters, it will
  be passed through optimistically. This will allow users to opt-in to using
  IDNA2003 themselves if they want to, and will also allow technically invalid
  but still common hostnames.
• Fixed an issue where URLs with leading whitespace would raise
  InvalidSchema errors.
• Fixed an issue where some URLs without the HTTP or HTTPS schemes would still
  have HTTP URL preparation applied to them.
• Fixed an issue where Unicode strings could not be used in basic auth.
• Fixed an issue encountered by some Requests plugins where constructing a
  Response object would cause Response.content to raise an
  AttributeError.

2.12.1

+++++++++++++++++++

Bugfixes

• Updated setuptools 'security' extra for the new PyOpenSSL backend in urllib3.

Miscellaneous

• Updated bundled urllib3 to 1.19.1.

2.12.0

+++++++++++++++++++

Improvements

• Updated support for internationalized domain names from IDNA2003 to IDNA2008.
  This updated support is required for several forms of IDNs and is mandatory
  for .de domains.
• Much improved heuristics for guessing content lengths: Requests will no
  longer read an entire StringIO into memory.
• Much improved logic for recalculating Content-Length headers for
  PreparedRequest objects.
• Improved tolerance for file-like objects that have no tell method but
  do have a seek method.
• Anything that is a subclass of Mapping is now treated like a dictionary
  by the data= keyword argument.
• Requests now tolerates empty passwords in proxy credentials, rather than
  stripping the credentials.
• If a request is made with a file-like object as the body and that request is
  redirected with a 307 or 308 status code, Requests will now attempt to
  rewind the body object so it can be replayed.

Bugfixes

• When calling response.close, the call to close will be propagated
  through to non-urllib3 backends.
• Fixed issue where the ALL_PROXY environment variable would be preferred
  over scheme-specific variables like HTTP_PROXY.
• Fixed issue where non-UTF8 reason phrases got severely mangled by falling
  back to decoding using ISO 8859-1 instead.
• Fixed a bug where Requests would not correctly correlate cookies set when
  using custom Host headers if those Host headers did not use the native
  string type for the platform.

Miscellaneous

• Updated bundled urllib3 to 1.19.
• Updated bundled certifi certs to 2016.09.26.

2.11.1

+++++++++++++++++++

Bugfixes

• Fixed a bug when using iter_content with decode_unicode=True for
  streamed bodies would raise AttributeError. This bug was introduced in
  2.11.
• Strip Content-Type and Transfer-Encoding headers from the header block when
  following a redirect that transforms the verb from POST/PUT to GET.

2.11.0

+++++++++++++++++++

Improvements

• Added support for the ALL_PROXY environment variable.
• Reject header values that contain leading whitespace or newline characters to
  reduce risk of header smuggling.

Bugfixes

• Fixed occasional TypeError when attempting to decode a JSON response that
  occurred in an error case. Now correctly returns a ValueError.
• Requests would incorrectly ignore a non-CIDR IP address in the NO_PROXY
  environment variables: Requests now treats it as a specific IP.
• Fixed a bug when sending JSON data that could cause us to encounter obscure
  OpenSSL errors in certain network conditions (yes, really).
• Added type checks to ensure that iter_content only accepts integers and
  None for chunk sizes.
• Fixed issue where responses whose body had not been fully consumed would have
  the underlying connection closed but not returned to the connection pool,
  which could cause Requests to hang in situations where the HTTPAdapter
  had been configured to use a blocking connection pool.

Miscellaneous

• Updated bundled urllib3 to 1.16.
• Some previous releases accidentally accepted non-strings as acceptable header values. This release does not.

1.10.0

---

New Features

elpy 1.12.0 -> 1.14.1

1.14.0

==================

• Fix staged-files-only with external diff tools

pylint 1.4.4 -> 1.6.5

1.6.3

===========================

Release date: 2016-07-18

• Do not crash when inferring uninferable exception types for docparams extension

 Close 998

1.6.2

===========================

Release date: TBA

• Do not crash when printing the help of options with default regular expressions

 Close 990

• More granular versions for deprecated modules.

 Close 991

1.6.1

===========================

Release date: 2016-07-07

• Use environment markers for supporting conditional dependencies.

1.6.0

===========================

Release date: 2016-07-03

• Added a new extension, pylint.extensions.mccabe, for warning
  about complexity in code.

• Deprecate support for --optimize-ast. Part of 975.

• Deprecate support for the HTML output. Part of 975.

• Deprecate support for --output-files. Part of 975.

• Fixed a documentation error for the check_docs extension. Fixes 735.

• Made the list of property-defining decorators configurable.

• Fix a bug where the top name of a qualified import was detected as unused variable.

 Close 923.

• bad-builtin is now an extension check.

• generated-members support qualified name through regular expressions.

 For instance, one can specify a regular expression as --generated-members=astroid.node_classes.*
 for ignoring every no-member error that is accessed as in `astroid.node_classes.missing.object`.

• Add the ability to ignore files based on regex matching, with the new --ignore-patterns
  option.

 This addresses issue 156 by allowing for multiple ignore patterns
 to be specified. Rather than clobber the existing ignore option, we
 introduced a new one called ignore-patterns.

• Added a new error, 'trailing-newlines', which is emitted when a file
  has trailing new lines.

 Closes issue 682.

• Add a new option, 'redefining-builtins-modules', for controlling the modules
  which can redefine builtins, such as six.moves and future.builtins.

 Close 464.

• 'reimported' is emitted when the same name is imported from different module.

 Close 162.

• Add a new recommendation checker, 'consider-iterating-dictionary', which is emitted
  which is emitted when a dictionary is iterated through .keys().

 Close 699

• Use the configparser backport for Python 2

 This fixes a problem we were having with comments inside values, which is fixed
 in Python 3's configparser.
 Close 828

• A new error was added, 'invalid-length-returned', when the __len__
  special method returned something else than a non-negative number.

 Close issue 557

• Switch to using isort internally for wrong-import-order.

 Closes 879.

• check_docs extension can find constructor parameters in init.

 Closes 887.

• Don't warn about invalid-sequence-index if the indexed object has unknown base
  classes.

 Closes 867

• Don't crash when checking, for super-init-not-called, a method defined in an if block.

• Do not emit import-error or no-name-in-module for fallback import blocks by default.

 Until now, we warned with these errors when a fallback import block (a TryExcept block
 that contained imports for Python 2 and 3) was found, but this gets cumbersome when
 trying to write compatible code. As such, we don't check these blocks by default,
 but the analysis can be enforced by using the new ``--analyse-fallback-block`` flag.

 Close 769.

1.5.5

===========================

Release date: 2016-03-21

• Let visit_importfrom from Python 3 porting checker be called when everything is disabled

 Because the visit method was filtering the patterns it was expecting to be activated,
 it didn't run when everything but one pattern was disabled, leading to spurious false 
 positives

 Close 852

• Don't emit unsubscriptable-value for classes with unknown
  base classes.

 Close 776.

• Use an OrderedDict for storing the configuration elements

 This fixes an issue related to impredictible order of the disable / enable
 elements from a config file. In certain cases, the disable was coming before
 the enable which resulted in classes of errors to be enabled, even though the intention
 was to disable them. The best example for this was in the context of running multiple
 processes, each one of it having different enables / disables that affected the output.

 Close 815

• Don't consider bare and broad except handlers as ignoring NameError,
  AttributeError and similar exceptions, in the context of checkers for
  these issues.

 Closes issue 826

1.5.4

===========================

Release date: 2016-01-15

• Merge StringMethodChecker with StringFormatChecker. This fixes a
  bug where disabling all the messages and enabling only a handful of
  messages from the StringFormatChecker would have resulted in no
  messages at all.

• Don't apply unneeded-not over sets.

1.5.3

===========================

Release date: 2016-01-11

• Handle the import fallback idiom with regard to wrong-import-order.

 Closes issue 750.

• Decouple the displaying of reports from the displaying of messages

 Some reporters are aggregating the messages instead of displaying
 them when they are available. The actual displaying was conflatted
 in the generate_reports. Unfortunately this behaviour was flaky
 and in the case of the JSON reporter, the messages weren't shown
 at all if a file had syntax errors or if it was missing.
 In order to fix this, the aggregated messages can now be
 displayed with Reporter.display_message, while the reports are
 displayed with display_reports.
 
 Closes issues 766 and 765.

• Ignore function calls with variadic arguments without a context.

 Inferring variadic positional arguments and keyword arguments
 will result into empty Tuples and Dicts, which can lead in
 some cases to false positives with regard to no-value-for-parameter.
 In order to avoid this, until we'll have support for call context
 propagation, we're ignoring such cases if detected.
 Closes issue 722.

• Treat AsyncFunctionDef just like FunctionDef nodes,
  by implementing visit_asyncfunctiondef in terms of
  visit_functiondef.

 Closes issue 767.

• Take in account kwonlyargs when verifying that arguments
  are defined with the check_docs extension.

 Closes issue 745.

• Suppress reporting 'unneeded-not' inside __ne__ methods

 Closes issue 749.

1.5.2

===========================

Release date: 2015-12-21

• Don't crash if graphviz is not installed, instead emit a
  warning letting the user to know.

 Closes issue 168.

• Accept only functions and methods for the deprecated-method checker.

 This prevents a crash which can occur when an object doesn't have
 .qname() method after the inference.

• Don't emit super-on-old-class on classes with unknown bases.
  Closes issue 721.

• Allow statements in if or try blocks containing imports.

 Closes issue 714. 

1.5.1

===========================

Release date: 2015-12-02

• Fix a crash which occurred when old visit methods are encountered
  in plugin modules. Closes issue 711.

• Add wrong-import-position to check_messages's decorator arguments
  for ImportChecker.leave_module
  This fixes an esoteric bug which occurs when ungrouped-imports and
  wrong-import-order are disabled and pylint is executed on multiple files.
  What happens is that without wrong-import-position in check_messages,
  leave_module will never be called, which means that the first non-import node
  from other files might leak into the current file,
  leading to wrong-import-position being emitted by pylint.

• Fix a crash which occurred when old visit methods are encountered
  in plugin modules. Closes issue 711.

• Don't emit import-self and cyclic-import for relative imports
  of modules with the same name as the package itself.
  Closes issues 708 and 706.

1.5.0

===========================

Release date: 2015-11-29

• Added multiple warnings related to imports. 'wrong-import-order'
  is emitted when PEP 8 recommendations regarding imports are not
  respected (that is, standard imports should be followed by third-party
  imports and then by local imports). 'ungrouped-imports' is emitted
  when imports from the same package or module are not placed
  together, but scattered around in the code. 'wrong-import-position'
  is emitted when code is mixed with imports, being recommended for the
  latter to be at the top of the file, in order to figure out easier by
  a human reader what dependencies a module has.
  Closes issue 692.

• Added a new refactoring warning, 'unneeded-not', emitted
  when an expression with the not operator could be simplified.
  Closes issue 670.

• Added a new refactoring warning, 'simplifiable-if-statement',
  used when an if statement could be reduced to a boolean evaluation
  of its test. Closes issue 698.

• Added a new refactoring warning, 'too-many-boolean-expressions',
  used when an if statement contains too many boolean expressions,
  which makes the code less maintainable and harder to understand.
  Closes issue 677.

• Property methods are shown as attributes instead of functions in
  pyreverse class diagrams. Closes Issue 284

• Add a new refactoring error, 'too-many-nested-blocks', which is emitted
  when a function or a method has too many nested blocks, which makes the
  code less readable and harder to understand. Closes issue 668.

• Add a new error, 'unsubscriptable-object', that is emitted when
  value used in subscription expression doesn't support subscription
  (i.e. doesn't define getitem method).

• Don't warn about abstract classes instantiated in their own
  body. Closes issue 627.

• Obsolete options are not present by default in the generated
  configuration file. Closes issue 632.

• non-iterator-returned can detect classes with iterator-metaclasses.
  Closes issue 679.

• Add a new error, 'unsupported-membership-test', emitted when value
  to the right of the 'in' operator doesn't support membership test
  protocol (i.e. doesn't define contains/iter/getitem)

• Add new errors, 'not-an-iterable', emitted when non-iterable value
  is used in an iterating context (starargs, for-statement,
  comprehensions, etc), and 'not-a-mapping', emitted when non-mapping
  value is used in a mapping context. Closes issue 563.

• Make 'no-self-use' checker not emit a warning if there is a 'super()'
  call inside the method.
  Closes issue 667.

• Add checker to identify multiple imports on one line.
  Closes issue 598.

• Fix unused-argument false positive when the "+=" operator is used.
  Closes issue 518.

• Don't emit import-error for ignored modules. PyLint will not emit import
  errors for any import which is, or is a subpackage of, a module in
  the ignored-modules list. Closes issue 223.

• Fix unused-import false positive when the import is used in a
  class assignment. Closes issue 475

• Add a new error, 'not-context-manager', emitted when something
  that doesn't implement enter and exit is used in a with
  statement.

• Add a new warning, 'confusing-with-statement', emitted by the
  base checker, when an ambiguous looking with statement is used.
  For example with open() as first, second which looks like a
  tuple assignment but is actually 2 context managers.

• Add a new warning, 'duplicate-except', emitted when there is an
  exception handler which handles an exception type that was handled
  before. Closes issue 485.

• A couple of warnings got promoted to errors, since they could uncover
  potential bugs in the code. These warnings are: assignment-from-none,
  unbalanced-tuple-unpacking, unpacking-non-sequence, non-iterator-returned.
  Closes issue 388.

• Allow ending a pragma control with a semicolon. In this way, users
  can continue a pragma control with a reason for why it is used,
  as in pylint: disable=old-style-class;reason=....
  Closes issue 449.

• --jobs can be used with --load-plugins now. Closes issue 456.

• Improve the performance of --jobs when dealing only with a package
  name. Closes issue 479.

• Don't emit an unused-wildcard-import when the imported name comes
  from another module and it is in fact a future name.

• The colorized reporter now works on Windows. Closes issue 96.

• Remove pointless-except warning. It was previously disabled by
  default and it wasn't very useful. Closes issue 506.

• Fix a crash on Python 3 related to the string checker, which
  crashed when it encountered a bytes string with a .format
  method called.

• Don't warn about no-self-use for builtin properties.

• Fix a false positive for bad-reversed-sequence, when a subclass
  of a dict provides a reversed method.

• Change the default no-docstring-rgx so missing-docstring isn't
  emitted for private functions.

• Don't emit redefined-outer-name for future directives.
  Closes issue 520.

• Provide some hints for the bad-builtin message. Closes issue 522.

• When checking for invalid arguments to a callable, in typecheck.py,
  look up for the init in case the found new comes from builtins.

 Since the __new__ comes from builtins, it will not have attached any
 information regarding what parameters it expects, so the check
 will be useless. Retrieving __init__ in that case will at least
 detect a couple of false negatives. Closes issue 429.

• Don't emit no-member for classes with unknown bases.

 Since we don't know what those bases might add, we simply ignore
 the error in this case.

• Lookup in the implicit metaclass when checking for no-member,
  if the class in question has an implicit metaclass, which is
  True for new style classes. Closes issue 438.

• Add two new warnings, duplicate-bases and inconsistent-mro.

 duplicate-bases is emitted when a class has the same bases
 listed more than once in its bases definition, while inconsistent-mro
 is emitted when no sane mro hierarchy can be determined. Closes issue 526.

• Remove interface-not-implemented warning. Closes issue 532.

• Remove the rest of interface checks: interface-is-not-class,
  missing-interface-method, unresolved-interface. The reason is that
  its better to start recommending ABCs instead of the old Zope era
  of interfaces. One side effect of this change is that ignore-iface-methods
  becomes a noop, it's deprecated and it will be removed at some time.

• Emit a proper deprecation warning for reporters.BaseReporter.add_message.

 The alternative way is to use handle_message. add_message will be removed in
 Pylint 1.6.

• Added new module 'extensions' for optional checkers with the test
  directory 'test/extensions' and documentation file 'doc/extensions.rst'.

• Added new checker 'extensions.check_docs' that verifies parameter
  documention in Sphinx, Google, and Numpy style.

• Detect undefined variable cases, where the "definition" of an undefined
  variable was in del statement. Instead of emitting used-before-assignment,
  which is totally misleading, it now emits undefined-variable.
  Closes issue 528.

• Don't emit attribute-defined-outside-init and access-member-before-definition
  for mixin classes. Actual errors can occur in mixin classes, but this is
  controlled by the ignore-mixin-members option. Closes issue 412.

• Improve the detection of undefined variables and variables used before
  assignment for variables used as default arguments to function,
  where the variable was first defined in the class scope.
  Closes issue 342 and issue 404.

• Add a new warning, 'unexpected-special-method-signature', which is emitted
  when a special method (dunder method) doesn't have the expected signature,
  which can lead to actual errors in the application code.
  Closes issue 253.

• Remove 'bad-context-manager' due to the inclusion of 'unexpected-special-method-signature'.

• Don't emit no-name-in-module if the import is guarded by an ImportError, Exception or
  a bare except clause.

• Don't emit no-member if the attribute access node is protected by an
  except handler, which handles AttributeError, Exception or it is a
  bare except.

• Don't emit import-error if the import is guarded by an ImportError, Exception or a
  bare except clause.

• Don't emit undefined-variable if the node is guarded by a NameError, Exception
  or bare except clause.

• Add a new warning, 'using-constant-test', which is emitted when a conditional
  statement (If, IfExp) uses a test which is always constant, such as numbers,
  classes, functions etc. This is most likely an error from the user's part.
  Closes issue 524.

• Don't emit 'raising-non-exception' when the exception has unknown
  bases. We don't know what those bases actually are and it's better
  to assume that the user knows what he is doing rather than emitting
  a message which can be considered a false positive.

• Look for a .pylintrc configuration file in the current folder,
  if pylintrc is not found. Dotted pylintrc files will not be searched
  in the parents of the current folder, as it is done for pylintrc.

• Add a new error, 'invalid-unary-type-operand', emitted when
  an unary operand is used on something which doesn't support that
  operation (for instance, using the unary bitwise inversion operator
  on an instance which doesn't implement invert).

• Take in consideration differences between arguments of various
  type of functions (classmethods, staticmethods, properties)
  when checking for arguments-differ. Closes issue 548.

• astroid.inspector was moved to pylint.pyreverse, since it belongs
  there and it doesn't need to be in astroid.

• astroid.utils.LocalsVisitor was moved to pylint.pyreverse.LocalsVisitor.

• pylint.checkers.utils.excepts_import_error was removed.
  Use pylint.chekcers.utils.error_of_type instead.

• Don't emit undefined-all-variables for nodes which can't be
  inferred (YES nodes).

• yield-outside-func is also emitted for yield from.

• Add a new error, 'too-many-star-expressions', emitted when
  there are more than one starred expression (*x) in an assignment.
  The warning is emitted only on Python 3.

• Add a new error, 'invalid-star-assignment-target', emitted when
  a starred expression (*x) is used as the lhs side of an assignment,
  as in *x = [1, 2]. This is not a SyntaxError on Python 3 though.

• Detect a couple of objects which can't be base classes (bool,
  slice, range and memoryview, which weren't detected until now).

• Add a new error for the Python 3 porting checker, import-star-module-level,
  which is used when a star import is detected in another scope than the
  module level, which is an error on Python 3. Using this will emit a
  SyntaxWarning on Python 2.

• Add a new error, 'star-needs-assignment-target', emitted on Python 3 when
  a Starred expression (*x) is not used in an assignment target. This is not
  caught when parsing the AST on Python 3, so it needs to be a separate check.

• Add a new error, 'unsupported-binary-operation', emitted when
  two a binary arithmetic operation is executed between two objects
  which don't support it (a number plus a string for instance).
  This is currently disabled, since the it exhibits way too many false
  positives, but it will be reenabled as soon as possible.

• New imported features from astroid into pyreverse: pyreverse.inspector.Project,
  pyreverse.inspector.project_from_files and pyreverse.inspector.interfaces.

 These were moved since they didn't belong in astroid.

• Enable misplaced-future for Python 3. Closes issue 580.

• Add a new error, 'nonlocal-and-global', which is emitted when a
  name is found to be both nonlocal and global in the same scope.
  Closes issue 581.

• ignored-classes option can work with qualified names (ignored-classes=optparse.Values)
  Closes issue 297.

• ignored-modules can work with qualified names as well as with Unix pattern
  matching for recursive ignoring. Closes issues 244.

• Improve detection of relative imports in non-packages, as well as importing
  missing modules with a relative import from a package.

• Don't emit no-init if not all the bases from a class are known.
  Closes issue 604.

• --no-space-check option accepts empty-line as a possible option.
  Closes issue 541.

• --generate-rcfile generates by default human readable symbols
  for the --disable option. Closes issue 608.

• Improved the not-in-loop checker to properly detect more cases.

• Add a new error, 'continue-in-finally', which is emitted when
  the continue keyword is found inside a finally clause, which
  is a SyntaxError.

• The --zope flag is deprecated and it is slated for removal
  in Pylint 1.6.

 The reason behind this removal is the fact that it's a specialized
 flag and there are solutions for the original problem:
 use --generated-members with the members that causes problems
 when using Zope or add AST transforms tailored to the zope
 project.

 At the same time, --include-ids and --symbols will also be removed
 in Pylint 1.6. Closes issue 570.

• missing-module-attribute was removed and the corresponding
  CLI option, required-attributes, which is slated for removal
  in Pylint 1.6.

• missing-reversed-argument was removed.

 The reason behind this is that this kind of errors should be
 detected by the type checker for *all* the builtins and not
 as a special case for the reversed builtin. This will happen
 shortly in the future.

• --comment flag is obsolete and it will be removed in Pylint 1.6.

• --profile flag is obsolete and it will be removed in Pylint 1.6.

• Add a new error, 'misplaced-bare-raise'.

 The error is used when a bare raise is not used inside an except clause.
 This can generate a RuntimeError in Python, if there are no active exceptions
 to be reraised. While it works in Python 2 due to the fact that the exception
 leaks outside of the except block, it's nevertheless a behaviour that
 a user shouldn't depend upon, since it's not obvious to the reader of the code
 what exception will be raised and it will not be compatible with Python 3 anyhow.
 Closes issue 633.

• Bring logilab-common's ureports into pylint.reporters.

 With this change, we moved away from depending on logilab-common,
 having in Pylint all the components that were used from logilab-common.
 The API should be considered an implementation detail and can change at
 some point in the future.
 Closes issue 621.

• reimported is emitted for reimported objects on the same line.

 Closes issue 639.

• Abbreviations of command line options are not supported anymore.

 Using abbreviations for CLI options was never considered to be
 a feature of pylint, this fact being only a side effect of using optparse.
 As this was the case, using --load-plugin or other abbreviation
 for --load-plugins never actually worked, while it also didn't raise
 an error. Closes issue 424.

• Add a new error, 'nonlocal-without-binding'

 The error is emitted on Python 3 when a nonlocal name is not bound
 to any variable in the parents scopes. Closes issue 582.

• 'deprecated-module' can be shown for modules which aren't
  available. Closes issue 362.

• Don't consider a class abstract if its members can't
  be properly inferred.

 This fixes a false positive related to abstract-class-instantiated.
 Closes issue 648.

• Add a new checker for the async features added by PEP 492.

• Add a new error, 'yield-inside-async-function', emitted on
  Python 3.5 and upwards when the yield statement is found inside
  a new coroutine function (PEP 492).

• Add a new error, 'not-async-context-manager', emitted when
  an async context manager block is used with an object which doesn't
  support this protocol (PEP 492).

• Add a new convention warning, 'singleton-comparison', emitted when
  comparison to True, False or None is found.

• Don't emit 'assigning-non-slot' for descriptors. Closes issue 652.

• Add a new error, 'repeated-keyword', when a keyword argument is passed
  multiple times into a function call.

 This is similar with redundant-keyword-arg, but it's mildly different
 that it needs to be a separate error.

• --enable=all can now be used. Closes issue 142.

• Add a new convention message, 'misplaced-comparison-constant',
  emitted when a constant is placed in the left hand side of a comparison,
  as in '5 == func()'. This is also called Yoda condition, since the
  flow of code reminds of the Star Wars green character, conditions usually
  encountered in languages with variabile assignments in conditional
  statements.

• Add a new convention message, 'consider-using-enumerate', which is
  emitted when code that uses range and len for iterating is encountered.
  Closes issue 684.

• Added two new refactoring messages, 'no-classmethod-decorator' and
  'no-staticmethod-decorator', which are emitted when a static method or a class
  method is declared without using decorators syntax.

 Closes issue 675.

tox 2.1.1 -> 2.6.0

2.6.0

---

• add "alwayscopy" config option to instruct virtualenv to always copy
  files instead of symlinking. Thanks Igor Duarte Cardoso (igordcard).

• pass setenv variables to setup.py during a usedevelop install.
  Thanks Eli Collins (eli-collins).

• replace all references to testrun.org with readthedocs ones.
  Thanks Oliver Bestwalter (obestwalter).

• fix 323 by avoiding virtualenv14 is not used on py32
  (although we don't officially support py32).
  Thanks Jason R. Coombs (jaraco).

• add Python 3.6 to envlist and CI.
  Thanks Andrii Soldatenko (andriisoldatenko).

• fix glob resolution from TOX_TESTENV_PASSENV env variable
  Thanks Allan Feldman (a-feld).

2.5.0

---

• slightly backward incompatible: fix issue310: the {posargs} substitution
  now properly preserves the tox command line positional arguments. Positional
  arguments with spaces are now properly handled.
  NOTE: if your tox invocation previously used extra quoting for positional arguments to
  work around issue310, you need to remove the quoting. Example:
  tox -- "'some string'" has to now be written simply as
  tox -- "some string"
  thanks holger krekel. You can set minversion = 2.5.0 in the [tox]
  section of tox.ini to make sure people using your tox.ini use the correct version.

• fix 359: add COMSPEC to default passenv on windows. Thanks
  anthrotype.

• add support for py36 and py37 and add py36-dev and py37(nightly) to
  travis builds of tox. Thanks John Vandenberg.

• fix 348: add py2 and py3 as default environments pointing to
  "python2" and "python3" basepython executables. Also fix 347 by
  updating the list of default envs in the tox basic example.
  Thanks Tobias McNulty.

• make "-h" and "--help-ini" options work even if there is no tox.ini,
  thanks holger krekel.

• add {:} substitution, which is replaced with os-specific path
  separator, thanks Lukasz Rogalski.

• fix 305: downloadcache test env config is now ignored as pip-8
  does caching by default. Thanks holger krekel.

• output from install command in verbose (-vv) mode is now printed to console instead of
  being redirected to file, thanks Lukasz Rogalski

• fix 399. Make sure {envtmpdir} is created if it doesn't exist at the
  start of a testenvironment run. Thanks Manuel Jacob.

• fix 316: Lack of commands key in ini file is now treated as an error.
  Reported virtualenv status is 'nothing to do' instead of 'commands
  succeeded', with relevant error message displayed. Thanks Lukasz Rogalski.

2.4.1

---

• fix issue380: properly perform substitution again. Thanks Ian
  Cordasco.

2.4.0

---

• remove PYTHONPATH from environment during the install phase because a
  tox-run should not have hidden dependencies and the test commands will also
  not see a PYTHONPATH. If this causes unforeseen problems it may be
  reverted in a bugfix release. Thanks Jason R. Coombs.

• fix issue352: prevent a configuration where envdir==toxinidir and
  refine docs to warn people about changing "envdir". Thanks Oliver Bestwalter and holger krekel.

• fix issue375, fix issue330: warn against tox-setup.py integration as
  "setup.py test" should really just test with the current interpreter. Thanks Ronny Pfannschmidt.

• fix issue302: allow cross-testenv substitution where we substitute
  with {x,y} generative syntax. Thanks Andrew Pashkin.

• fix issue212: allow escaping curly brace chars "{" and "}" if you need the
  chars "{" and "}" to appear in your commands or other ini values.
  Thanks John Vandenberg.

• addresses issue66: add --workdir option to override where tox stores its ".tox" directory
  and all of the virtualenv environment. Thanks Danring.

• introduce per-venv list_dependencies_command which defaults
  to "pip freeze" to obtain the list of installed packages.
  Thanks Ted Shaw, Holger Krekel.

• close issue66: add documentation to jenkins page on how to avoid
  "too long shebang" lines when calling pip from tox. Note that we
  can not use "python -m pip install X" by default because the latter
  adds the CWD and pip will think X is installed if it is there.
  "pip install X" does not do that.

• new list_dependencies_command to influence how tox determines
  which dependencies are installed in a testenv.

• (experimental) New feature: When a search for a config file fails, tox tries loading
  setup.cfg with a section prefix of "tox".

• fix issue275: Introduce hooks tox_runtest_pre``` and tox_runtest_post`` which run before and after the tests of a venv,
  respectively. Thanks to Matthew Schinckel and itxaka serrano.

• fix issue317: evaluate minversion before tox config is parsed completely.
  Thanks Sachi King for the PR.

• added the "extras" environment option to specify the extras to use when doing the
  sdist or develop install. Contributed by Alex Grönholm.

• use pytest-catchlog instead of pytest-capturelog (latter is not
  maintained, uses deprecated pytest API)

2.3.2

---

• fix issue314: fix command invocation with .py scripts on windows.

• fix issue279: allow cross-section substitution when the value contains
  posargs. Thanks Sachi King for the PR.

2.3.1

---

• fix issue294: re-allow cross-section substitution for setenv.

2.3.0

---

• DEPRECATE use of "indexservers" in tox.ini. It complicates
  the internal code and it is recommended to rather use the
  devpi system for managing indexes for pip.

• fix issue285: make setenv processing fully lazy to fix regressions
  of tox-2.2.X and so that we can now have testenv attributes like
  "basepython" depend on environment variables that are set in
  a setenv section. Thanks Nelfin for some tests and initial
  work on a PR.

• allow "" in commands. This is slightly incompatible with commands
  sections that used a comment after a "&quot; line continuation.
  Thanks David Stanek for the PR.

• fix issue289: fix build_sphinx target, thanks Barry Warsaw.

• fix issue252: allow environment names with special characters.
  Thanks Julien Castets for initial PR and patience.

• introduce experimental tox_testenv_create(venv, action) and
  tox_testenv_install_deps(venv, action) hooks to allow
  plugins to do additional work on creation or installing
  deps. These hooks are experimental mainly because of
  the involved "venv" and session objects whose current public
  API is not fully guranteed.

• internal: push some optional object creation into tests because
  tox core doesn't need it.

2.2.1

---

• fix bug where {envdir} substitution could not be used in setenv
  if that env value is then used in {basepython}. Thanks Florian Bruhin.

2.2.0

---

• fix issue265 and add LD_LIBRARY_PATH to passenv on linux by default
  because otherwise the python interpreter might not start up in
  certain configurations (redhat software collections). Thanks David Riddle.

• fix issue246: fix regression in config parsing by reordering
  such that {envbindir} can be used again in tox.ini. Thanks Olli Walsh.

• fix issue99: the {env:...} substitution now properly uses environment
  settings from the setenv section. Thanks Itxaka Serrano.

• fix issue281: make --force-dep work when urls are present in
  dependency configs. Thanks Glyph Lefkowitz for reporting.

• fix issue174: add new ignore_outcome testenv attribute which
  can be set to True in which case it will produce a warning instead
  of an error on a failed testenv command outcome.
  Thanks Rebecka Gulliksson for the PR.

• fix issue280: properly skip missing interpreter if
  {envsitepackagesdir} is present in commands. Thanks BB:ceridwenv
