0.10.6 (2016-09-22)

  • fix missing configuration field

0.10.5 (2016-09-20)

  • add support for different vote levels, #260

    List of vote levels used to customize comment appearance based on score. Provide a comma-separated values (eg. "0,5,10,25,100") or a JSON array (eg. "[-5,5,15]").

    For example, the value "-5,5" will cause each isso-comment to be given one of these 3 classes:

    • isso-vote-level-0 for scores lower than -5
    • isso-vote-level-1 for scores between -5 and 4
    • isso-vote-level-2 for scores of 5 and greater

    These classes can then be used to customize the appearance of comments (eg. put a star on popular comments).

  • add new post preview API endpoint, #254

  • add an option for mandatory author, #257

  • clients can now use data-title to get the HTML title for a new page, #252

  • add finish translation and other minor bugfixes

0.10.4 (2016-04-12)

  • fix wrapper attribute when using data-isso-require-mail="true", #238
  • fix reponse for OPTIONS response on Python 3, #242

0.10.3 (2016-02-24)

  • follow redirects, #193

0.10.2 (2016-02-21)

  • fix getAttribute return value

0.10.1 (2016-02-06)

  • fix empty author, email and website values when writing a comment

0.10 (2016-02-06)

  • add new configuration section for hash handling.

    [hash] salt = Eech7co8Ohloopo9Ol6baimi algorithm = pbkdf2

    You can customize the salt, choose different hash functions and tweak the parameters for PBKDF2.

  • Python 3.4+ validate TLS connections against the system's CA. Previously no validation was in place, see PEP-446 for details.

  • add fenced_code and no_intra_emphasis to default configuration.

    Fenced code allows to write code without indentation using ~~~ delimiters (optionally with language identifier).

    Intra emphasis would compile foo_bar_baz to foo<em>bar</em>baz. This behavior is very confusing for users not knowing the Markdown spec in detail.

  • new configuration to require an email when submitting comments, #199. Set

    [guard] require-email = true

    and use data-isso-require-email="true" to enable this feature. Disabled by default.

  • new Bulgarian translation by sahwar, new Swedish translation by Gustav Näslund – #143, new Vietnamese translation by Đinh Xuân Sâm, new Croatian translation by streger, new Czech translation by Jan Chren

  • fix SMTP setup without credentials, #174

  • version pin Misaka to 1.x, html5lib to 0.9999999

0.9.10 (2015-04-11)

  • fix regression in SMTP authentication, #174

0.9.9 (2015-03-04)

  • several Python 3.x related bugfixes
  • don't lose comment form if the server rejected the POST request, #144
  • add localStorage fallback if QUOTA_EXCEEDED_ERR is thrown (e.g. Safari private browsing)
  • add '--empty-id' flag to Disqus import, because Disqus' export sucks
  • (re)gain compatibility with Werkzeug 0.8 and really old html5lib versions available in Debian Squeeze, #170 & #168
  • add User-Agent when Isso requests the URL, an alternate way to #151 (add 'X-Isso' when requesting).

0.9.8 (2014-10-08)

  • add compatibility with configparser==3.5.0b1, #128

0.9.7 (2014-09-25)

  • fix SMTP authentication using CRAM-MD5 (incorrect usage of smtplib), #126

0.9.6 (2014-08-18)

  • remember name, email and website in localStorage, #119

  • add option to hide voting feature, #115

    data-isso-vote="true|false"

  • remove email field from JSON responses

    This is a quite serious issue. For the identicon, an expensive hash is used to avoid the leakage of personal information like a real email address. A git blame reveals, the email has been unintenionally exposed since the very first release of Isso :-/

    The testsuite now contains a dedicated test to prevent this error in the future.

0.9.5 (2014-08-10)

  • prevent no-break space (&nbsp;) insertion to enable manual line breaks using two trailing spaces (as per Markdown convention), #112

  • limit request size to 256 kb, #107

    Previously unlimited or limited by proxy server). 256 kb is a rough approximation of the next database schema with comments limited to 65535 characters and additional fields.

  • add support for logging to file, #103

    [general] log-file =

  • show timestamp when hovering <time>, #104

  • fix a regression when editing comments with multiple paragraphs introduced in 0.9.3 which would HTML escape manually inserted linebreaks.

0.9.4 (2014-07-09)

  • fixed a regression when using Isso and Gevent

0.9.3 (2014-07-09)

  • remove scrollIntoView while expanding further comments if a fragment is used (e.g. #isso-thread brought you back to the top, unexpectedly)
  • implement a custom Markdown renderer to support multi-line code listings. The extension "fenced_code" is now enabled by default and generates HTML compatible with Highlight.js.
  • escape HTML entities when editing a comment with raw HTML
  • fix CSS for input
  • remove isso.css from binary distribution to avoid confusion (it's still there from the very first release, but modifications do not work)

0.9 (2014-05-29)

  • comment pagination by Srijan Choudhary, #15

    Isso can now limit the amount of comments shown by default and add link to show more. By default, all top-level comments are shown but only 5 nested comments (per reply). You can override the settings:

    isso-data-max-comments-top="N" isso-data-max-comments-nested="N"

    Where N is a number from 0 to infinity ("inf"). If you limit the amount of shown top level comments, the overall comment count may be incorrect and a known issue.

    You can also configure the amount of comments shown per click (5 by default):

    isso-data-reveal-on-click="N"

    This feature also required a change in the comment structure. Previously, all comments are stored tree-like but shown linearly. To ease the implementation of pagination, the comment tree is now limited to a maximum depth of one. Jeff Atwood explains, why discussions are flat by design.

    When you upgrade, Isso will automatically normalize the tree and some information gets lost. All new replies to a comment are now automatically a direct child of the top-level comment.

  • style improvements by William Dorffer, #39, #84 #90 and #91

    Isso now longer uses a fat SCSS library, but plain CSS instead. The design is now responsive and no longer sets global CSS rules.

  • experimental WordPress import, #75

    Isso should be able to import WXR 1.0-1.2 exports. The import code is based on two WXR dumps I found (and created) and may not work for you. Please report any failure.

  • avatar changes, #49

    You can now configure the client to not show avatars:

    data-isso-avatar="false"

    Also there is no longer an avatar shown next to the comment box. This is due to the new CSS and removes two runtime dependencies.

  • you may now set a full From header, #87

    [smtp] from = Foo Bar <spam@local>

  • SMTP (all caps) is now recognized for notifications, #95

  • Isso now ships a small demo site at /demo, #44

  • a few bugfixes: Disqus import now anonymizes IP addresses, uWSGI spooling for Python 3, HTTP-Referer fallback for HTTP-Origin

  • remove Django's PBKDF2 implementation in favour of the PBKDF2 function available in werkzeug 0.9 or higher. If you're still using werkzeug 0.8, Isso imports passlib as fallback (if available).

This release also features a new templating engine Jade which replaces Markup.js. Jade can compile directly to JavaScript with a tiny runtime module on the client. Along with the removal of sha1.js and pbkdf2.js and a few build optimizations, the JS client now weighs only 40kb (12kb gzipped) – 52kb resp. 17kb before.

0.8 (2014-03-28)

  • replace <textarea> with <div contentedtiable="true"> to remove the sluggish auto-resize on input feature. If you use a custom CSS, replace textarea with .textarea and also set white-space: pre.

  • remove superscript extension from Markdown defaults as it may lead to unexpected behavior for certain smileys such as "^^". To enable the extension, add

    [markup] options = superscript allowed-elements = sup

    to your configuration.

  • comment count requests are now bundled into a single POST request, but the old API is still there (deprecated though).

  • store session-key in database (once generated on database creation). That means links to activate, edit or delete comments are now always valid even when you restart Isso.

    Currently statically set session keys in [general] are automatically migrated into the database on startup and you will get a notice that you can remove this option.

  • fix undefined timestamp when client time differs for more than 1 second. The human-readable "time ago" deltas have been refined to match Moment.js behavior.

  • avatar colors and background can now be customized:

    • data-isso-avatar-bg="#f0f0f0" sets the background color
    • data-isso-avatar-fg="#9abf88 #5698c4 #e279a3 #9163b6 ..." sets possible avatar colors (up to 8 colors are possible).
  • new [markup] section to customize Misaka's Markdown generation (strikethrough, superscript and autolink enabled by default). Furthermore, you can now allow certain HTML elemenets and attributes in the generated output, e.g. to enable images, set

    [markup] allowed-elements = img allowed-attributes = src

    Check docs/configuration/server.rst for more details.

  • replace requirejs-domready with a (self-made) HTML5 idiom, #51

0.7 (2014-01-29)

  • fix malicious HTML injection (due to wrong API usage). All unknown/unsafe HTML tags are now removed from the output (html5lib 0.99(9) or later) or properly escaped (older html5lib versions).

    See 36d702c and 3a1f92b for more details.

  • remove kriskowal/q JS library (promises implementation) in favour of a self-made 50 LoC implementation to ease packaging (for Debian), #51

  • add documentation to display a comment counter, #56 and #57

  • SMTP notifications now support STARTTLS and use this transport security by default, #48 and #58. This also changes the configuration option from ssl = [yes|no] to security = [none|starttls|ssl].

  • translation can now be made (and updated) with Transifex. If you want to take ownership for a language, contact me on IRC.

  • fix french pluralform

  • the (by default random) session-key is now shown on application startup to make different keys per startup more visible

  • use threading.lock by default for systems without semaphore support

0.6 (2013-12-16)

Major improvements:

  • override thread discovery with data-isso-id="...", #27

    To use the same thread for different URLs, you can now add a custom data-isso-id="my-id" attribute which is used to identify and retrieve comments (defaults to current URL aka window.location.pathname).

  • isso.dispatch now dispatches multiple websites (= configurations) based on URL prefixes

  • fix a cross-site request forgery vulnerability for comment creation, voting, editing and deletion, #40

  • show modal dialog to confirm comment deletion and activation, #36

  • new, comprehensive documentation based on reST + Sphinx: http://posativ.org/docs (or docs/ in the repository). Also includes an annotated example.conf, #43

  • new italian and russian translations

Minor improvements:

  • move isso:application to isso.run:application to avoid uneccessary initialization in some cases (change module if you use uWSGI or Gunicorn)
  • add Date header to email notifications, #42
  • check for blank text in new comment, #41
  • work around IE10's HTML5 abilities for custom data-attributes
  • add support for Gunicorn (and other pre-forking WSGI servers)

0.5 (2013-11-17)

Major improvements:

  • listen option replaces host and port to support UNIX domain sockets, #25

    Instead of host = localhost and port = 8080, use listen = http://localhost:8080. To listen on a UNIX domain socket, replace http:// with unix://, e.g. unix:///tmp/isso.sock.

  • new option notify (in the general section) is used to choose (one or more) notification backends (currently only SMTP is available, though). Isso will no longer automatically use SMTP for notifications if the initial connection succeeds.

  • new options to control the client integration

    • data-isso-css="false" prevents the client from appending the CSS to the document. Enabled by default.
    • data-isso-lang="de" overrides the useragent's preferred language (de, en and fr are currently supported).
    • data-isso-reply-to-self="true" should be set, when you allow reply to own comments (see server configuration for details).
  • add support for gevent, a coroutine-based Python networking library that uses greenlets (lightweight threads). Recommended WSGI server when not running with uWSGI (unfortunately stable gevent is not yet able to listen on a UNIX domain socket).

  • fix a serious issue with the voters bloomfilter. During an Isso run, the ip addresses from all commenters accumulated into the voters bloomfilter for new comments. Thus, previous commenters could no longer vote other comments. This fixes the rare occurences of #5.

    In addition to this fix, the current voters bloomfilter will be re-initialized if you are using Isso 0.4 or below (this is not necessary, but on the other hand, the current bloomfilter for each comment is sort-of useless).

  • french translation (thanks to @sploinga), #38

  • support for multiple sites, part of #34

Minor improvements:

  • ipaddr is now used as ipaddress fallback for Python 2.6 and 2.7, #32
  • changed URL to activate and delete comments to /id/<N:int>/activate etc.
  • import command uses <link> tag instead of <id> to extract the relative URL path, #37
  • import command now uses isDeleted to mark comments as deleted (and eventually remove stale comments). This seems to affect only a few comments from a previous WordPress import into Disqus.
  • import command lists orphaned comments after import.
  • import command now has a --dry-run option to do no actual operation on the database.

0.4 (2013-11-05)

  • Isso now handles cross-domain requests and cookies, fixes #24
  • Isso for Python 2.x now supports werkzeug>=0.8
  • limit email length to 254 to avoid Hash-DDoS
  • override Isso API location with data-isso="..." in the script tag
  • override HTML title parsing with a custom data-title="..." attribute in <div id="isso-thread"></div>

0.3 (2013-11-01)

  • improve initial comment loading performance in the client
  • cache slow REST requests, see #18
  • add a SQLite trigger that detects and removes stale threads (= threads, with all comments being removed) from the database when a comment is removed.
  • PyPi releases now include an uncompressed version of the JavaScript files -- embed.dev.js and count.dev.js -- to track down errors.
  • use uWSGI's internal locking instead of a self-made shared memory lock

0.2 (2013-10-29)

  • initial PyPi release
