Fixes:

  • Fixed cal.Component.from_ical() representing an unknown component as one of the known. [stlaz]
  • Fixed possible IndexError exception during parsing of an ical string. [stlaz]
  • When doing a boolean test on icalendar.cal.Component, always return True. Before it was returning False due to CaselessDict, if it didn't contain any items. [stlaz]

  • Added __version__ attribute to init.py. [TomTry]
  • Documentation fixes. [TomTry]
  • Pep 8, UTF 8 headers, dict/list calls to literals. [thet]

3.9.1 (2015-09-08)

  • Fix vPeriod.__repr__. [spacekpe]
  • Improve foldline() performance. This improves the foldline performance, especially for large strings like base64-encoded inline attachements. In some cases (1MB string) from 7 Minutes to less than 20ms for ASCII data and 500ms for non-ASCII data. Ref: #163. [emfree]

3.9.0 (2015-03-24)

  • Creating timezone objects from VTIMEZONE components. [geier]
  • Make python-dateutil a dependency. [geier]
  • Made RRULE tolerant of trailing semicolons. [sleeper]
  • Documentation fixes. [t-8ch, thet]

3.8.4 (2014-11-01)

  • Add missing BYWEEKNO to recurrence rules. [russkel]

3.8.3 (2014-08-26)

  • PERCENT property in VTODO renamed to PERCENT-COMPLETE, according to RFC5545. [thomascube]

3.8.2 (2014-07-22)

  • Exclude editor backup files from egg distributions. Fixes #144. [thet]

3.8.1 (2014-07-17)

  • The representation of CaselessDicts in 3.8 changed the name attribute of Components and therefore broke the external API. This has been fixed. [untitaker]

3.8 (2014-07-17)

  • Allow dots in property names (Needed for vCard compatibility). Refs #143. [untitaker]
  • Change class representation for CaselessDict objects to always include the class name or the class' name attribute, if available. Also show subcomponents for Component objects. [thet]
  • Don't use data_encode for CaselessDict class representation but use dict's __repr__ method. [t-8ch]

3.7 (2014-06-02)

  • For components with ignore_exceptions set to True, mark unparseable lines as broken instead rising a ValueError. VEVENT components have ignore_exceptions set to True by default. Ref #131. Fixes #104. [jkiang13]
  • Make python-dateutil a soft-dependency. [boltnev]
  • Add optional sorted parameter to Component.to_ical. Setting it to false allows the user to preserve the original property and parameter order. Ref #136. Fixes #133. [untitaker]
  • Fix tests for latest pytz. Don't set tzinfo directly on datetime objects, but use pytz's localize function. Ref #138. [untitaker, thet]

3.6.2 (2014-04-05)

  • Pep8 and cleanup. [lasudry]

3.6.1 (2014-01-13)

  • Open text files referenced by setup.py as utf-8, no matter what the locale settings are set to. Fixes #122. [sochotnicky]
  • Add tox.ini to source tarball, which simplifies testing for in distributions. [sochotnicky]

3.6 (2014-01-06)

  • Python3 (3.3+) + Python 2 (2.6+) support [geier]
  • Made sure to_ical() always returns bytes [geier]
  • Support adding lists to a component property, which value already was a list and remove the Component.set method, which was only used by the add method. [thet]
  • Remove ability to add property parameters via a value's params attribute when adding via cal.add (that was only possible for custom value objects and makes up a strange API), but support a parameter attribute on cal.add's method signature to pass a dictionary with property parameter key/value pairs. Fixes #116. [thet]
  • Backport some of Regebro's changes from his regebro-refactor branch. [thet]
  • Raise explicit error on another malformed content line case. [hajdbo]
  • Correctly parse datetime component property values with timezone information when parsed from ical strings. [untitaker]

3.5 (2013-07-03)

  • Let to_unicode be more graceful for non-unicode strings, as like CMFPlone's safe_unicode does it. [thet]

3.4 (2013-04-24)

  • Switch to unicode internally. This should fix all en/decoding errors. [thet]
  • Support for non-ascii parameter values. Fixes #88. [warvariuc]
  • Added functions to transform chars in string with '\' + any of r',;:' chars into '%{:02X}' form to avoid splitting on chars escaped with '\'. [warvariuc]
  • Allow seconds in vUTCOffset properties. Fixes #55. [thet]
  • Let Component.decode better handle vRecur and vDDDLists properties. Fixes #70. [thet]
  • Don't let Component.add re-encode already encoded values. This simplifies the API, since there is no need explicitly pass encode=False. Fixes #82. [thet]
  • Rename tzinfo_from_dt to tzid_from_dt, which is what it does. [thet]
  • More support for dateutil parsed tzinfo objects. Fixes #89. [leo-naeka]
  • Remove python-dateutil version fix at all. Current python-dateutil has Py3 and Py2 compatibility. [thet]
  • Declare the required python-dateutil dependency in setup.py. Fixes #90. [kleink]
  • Raise test coverage. [thet]
  • Remove interfaces module, as it is unused. [thet]
  • Remove test_doctests.py, test suite already created properly in test_icalendar.py. [rnix]
  • Transformed doctests into unittests, Test fixes and cleanup. [warvariuc]

3.3 (2013-02-08)

  • Drop support for Python < 2.6. [thet]
  • Allow vGeo to be instantiated with list and not only tuples of geo coordinates. Fixes #83. [thet]
  • Don't force to pass a list to vDDDLists and allow setting individual RDATE and EXDATE values without having to wrap them in a list. [thet]
  • Fix encoding function to allow setting RDATE and EXDATE values and not to have bypass encoding with an icalendar property. [thet]
  • Allow setting of timezone for vDDDLists and support timezone properties for RDATE and EXDATE component properties. [thet]
  • Move setting of TZID properties to vDDDTypes, where it belongs to. [thet]
  • Use @staticmethod decorator instead of wrapper function. [warvariuc, thet]
  • Extend quoting of parameter values to all of those characters: ",;: â��'". This fixes an outlook incompatibility with some characters. Fixes: #79, Fixes: #81. [warvariuc]
  • Define VTIMETZONE subcomponents STANDARD and DAYLIGHT for RFC5545 compliance. [thet]

3.2 (2012-11-27)

  • Documentation file layout restructuring. [thet]
  • Fix time support. vTime events can be instantiated with a datetime.time object, and do not inherit from datetime.time itself. [rdunklau]
  • Correctly handle tzinfo objects parsed with dateutil. Fixes #77. [warvariuc, thet]
  • Text values are escaped correclty. Fixes #74. [warvariuc]
  • Returned old folding algorithm, as the current implementation fails in some cases. Fixes #72, Fixes #73. [warvariuc]
  • Supports to_ical() on date/time properties for dates prior to 1900. [cdevienne]

3.1 (2012-09-05)

  • Make sure parameters to certain properties propagate to the ical output. [kanarip]
  • Re-include doctests. [rnix]
  • Ensure correct datatype at instance creation time in prop.vCalAddress and prop.vText. [rnix]
  • Apply TZID parameter to datetimes parsed from RECURRENCE-ID [dbstovall]
  • Localize datetimes for timezones to avoid DST transition errors. [dbstovall]
  • Allow UTC-OFFSET property value data types in seconds, which follows RFC5545 specification. [nikolaeff]
  • Remove utctz and normalized_timezone methods to simplify the codebase. The methods were too tiny to be useful and just used at one place. [thet]
  • When using Component.add() to add icalendar properties, force a value conversion to UTC for CREATED, DTSTART and LAST-MODIFIED. The RFC expects UTC for those properties. [thet]
  • Removed last occurrences of old API (from_string). [Rembane]
  • Add 'recursive' argument to property_items() to switch recursive listing. For example when parsing a text/calendar text including multiple components (e.g. a VCALENDAR with 5 VEVENTs), the previous situation required us to look over all properties in VEVENTs even if we just want the properties under the VCALENDAR component (VERSION, PRODID, CALSCALE, METHOD). [dmikurube]
  • All unit tests fixed. [mikaelfrykholm]

3.0.1b2 (2012-03-01)

  • For all TZID parameters in DATE-TIME properties, use timezone identifiers (e.g. Europe/Vienna) instead of timezone names (e.g. CET), as required by RFC5545. Timezone names are used together with timezone identifiers in the Timezone components. [thet]
  • Timezone parsing, issues and test fixes. [mikaelfrykholm, garbas, tgecho]
  • Since we use pytz for timezones, also use UTC tzinfo object from the pytz library instead of own implementation. [thet]

3.0.1b1 (2012-02-24)

  • Update Release information. [thet]

3.0

  • Add API for proper Timezone support. Allow creating ical DATE-TIME strings with timezone information from Python datetimes with pytz based timezone information and vice versa. [thet]
  • Unify API to only use to_ical and from_ical and remove string casting as a requirement for Python 3 compatibility: New: to_ical. Old: ical, string, as_string and string casting via __str__ and str. New: from_ical. Old: from_string. [thet]

2.2 (2011-08-24)

2.1 (2009-12-14)

  • Fix deprecation warnings about object.__init__ taking no parameters.
  • Set the VALUE parameter correctly for date values.
  • Long binary data would be base64 encoded with newlines, which made the iCalendar files incorrect. (This still needs testing).
  • Correctly handle content lines which include newlines.

2.0.1 (2008-07-11)

  • Made the tests run under Python 2.5+
  • Renamed the UTC class to Utc, so it would not clash with the UTC object, since that rendered the UTC object unpicklable.

2.0 (2008-07-11)

  • EXDATE and RDATE now returns a vDDDLists object, which contains a list of vDDDTypes objects. This is do that EXDATE and RDATE can contain lists of dates, as per RFC.

    *Note!*: This change is incompatible with earlier behavior, so if you handle EXDATE and RDATE you will need to update your code.

  • When createing a vDuration of -5 hours (which in itself is nonsensical), the ical output of that was -P1DT19H, which is correct, but ugly. Now it's '-PT5H', which is prettier.

1.2 (2006-11-25)

  • Fixed a string index out of range error in the new folding code.

1.1 (2006-11-23)

  • Fixed a bug in caselessdicts popitem. (thanks to Michael Smith <msmith@fluendo.com>)
  • The RFC 2445 was a bit unclear on how to handle line folding when it happened to be in the middle of a UTF-8 character. This has been clarified in the following discussion: http://lists.osafoundation.org/pipermail/ietf-calsify/2006-August/001126.html And this is now implemented in iCalendar. It will not fold in the middle of a UTF-8 character, but may fold in the middle of a UTF-8 composing character sequence.

1.0 (2006-08-03)

  • make get_inline and set_inline support non ascii codes.
  • Added support for creating a python egg distribution.

0.11 (2005-11-08)

  • Changed component .from_string to use types_factory instead of hardcoding entries to 'inline'
  • Changed UTC tzinfo to a singleton so the same one is used everywhere
  • Made the parser more strict by using regular expressions for key name, param name and quoted/unquoted safe char as per the RFC
  • Added some tests from the schooltool icalendar parser for better coverage
  • Be more forgiving on the regex for folding lines
  • Allow for multiple top-level components on .from_string
  • Fix vWeekdays, wasn't accepting relative param (eg: -3SA vs -SA)
  • vDDDTypes didn't accept negative period (eg: -P30M)
  • 'N' is also acceptable as newline on content lines, per RFC

0.10 (2005-04-28)

  • moved code to codespeak.net subversion.
  • reorganized package structure so that source code is under 'src' directory. Non-package files remain in distribution root.
  • redid doc/.py files as doc/.txt, using more modern doctest. Before they were .py files with big docstrings.

  • added test.py testrunner, and tests/test_icalendar.py that picks up all doctests in source code and doc directory, and runs them, when typing:

    python2.3 test.py
  • renamed iCalendar to lower case package name, lowercased, de-pluralized and shorted module names, which are mostly implementation detail.
  • changed tests so they generate .ics files in a temp directory, not in the structure itself.
