Editing Trac (section)

== History ==
Inspired by CVSTrac, Jonas Borgström and Daniel Lundin from Edgewall Software started writing ''svntrac'' in August 2003 using [[SQLite]] and [[Apache Subversion|Subversion]].<ref name="trachistory">{{cite web |date=March 1, 2004 |title=TracHistory - The Trac Project |publisher=Edgewall Trac |url=http://trac.edgewall.org/wiki/TracHistory |access-date=September 17, 2016 }}</ref> In December 2003 they renamed it to ''Trac''. In February 2004 the Trac version was changed first from 0.0.1 to 0.1 and then directly from 0.1 to 0.5. That release was followed in March 2004 by 0.6 and 0.7, and 0.8 in November 2004.

Edgewall Software is an umbrella organization for hosting edgewall.org for the community to collaborate on developing open source Python software.<ref name="edgewall">{{cite web |date=May 17, 2010 |title=EdgewallSoftware - The Trac Project |publisher=Edgewall Trac |url=http://trac.edgewall.org/wiki/TracHistory |access-date=September 17, 2016 }}</ref> It used to offer software development, consulting and support services. Some of the earliest community members to collaborate in the open source development of Trac were Rocky Burt in March 2004, Christopher Lenz and Francois Harvey in May 2004, Christian Boos and Otavio Salvador in December 2004 and Mark Rowe March 2005.<ref name="tracteam">{{cite web |date=July 21, 2016 |title=TracTeam - The Trac Project |publisher=Edgewall Trac |url=http://trac.edgewall.org/wiki/TracHistory |access-date=September 17, 2016 }}</ref>

In August 2005 the license was changed from [[GNU General Public License|GPL-2.0-or-later]] to [[BSD licenses|BSD-3-Clause]]. The first release under this final license was Trac 0.9 in October 2005, which among other features introduced [[PostgreSQL]] database support.

Trac 0.10, released in September 2006, was an important release that first introduced the component system that to this day allows plugins to extend and add features to Trac's core. Trac itself since this point consists mainly of optional plugin components that can be disabled or replaced entirely. [[MySQL]] database support is added as one such core component. This release added support for [[version control systems]] other than Subversion by external plugins. [[Mercurial]] support was provided through a separate plugin due to its GPL license restrictions.<ref name="mercurial-gpl">{{cite mailing list |url=https://groups.google.com/d/msg/trac-users/iizAo6QEO3A/O3zjVvkmvLcJ  |title=[Trac] The future of RepositoryHookSystem plugin  |date=May 6, 2010 |access-date=September 17, 2016 |mailing-list=trac-users |last=Blank |first=Remy }}</ref> Trac 0.11, released in June 2008, changed the HTML [[web template system|template system]] from ClearSilver<ref name="clearsilver">{{cite web |date=January 27, 2007 |title=ClearSilver - The Trac Project |publisher=Edgewall Trac |url=http://trac.edgewall.org/wiki/ClearSilver |access-date=February 6, 2007 }}</ref> to [[Genshi (templating language)|Genshi]], breaking compatibility with many of the older plugins.

Trac 0.12 was released in June 2010 and became a stable long term release with the latest point release 0.12.7 from July 2015. It added [[internationalization and localization]] support using ''Babel'', and allows using multiple version control repositories at once.

Trac 1.0 was released in September 2012,<ref name="release-announcement-1.0">{{cite mailing list |url=https://groups.google.com/d/msg/trac-dev/Zi93q4M_pBY/V7ONGcewhcsJ |title=Trac 1.0 released  |date=September 9, 2012 |access-date=September 17, 2016 |mailing-list=trac-dev |last=Boos |first=Christian }}</ref> the previous stable long term supported version with the latest point release 1.0.13 from September 2016. It included the previously external plugin for [[Git]] version control support.

Trac 1.1.1 from February 2013 through 1.1.6 from July 2015 are releases without long-term support and compatibility guarantees, that turned into Trac 1.2 from November 2016.<ref name="release-announcement-1.2">{{cite mailing list |url=https://groups.google.com/forum/#!topic/trac-announce/pxQJSaf0WJs |title=Trac 1.2 Released |date=November 5, 2016 |access-date=December 27, 2016 |mailing-list=trac-announce |last=Ollos |first=Ryan }}</ref>

Trac 1.4 from August 2019 was the last stable release running on Python 2.7. It uses the [[Jinja (template engine)|Jinja]] template system.

Trac 1.6 from September 2023 is the current stable release and works exclusively on Python3. Many of the plugins have also been rewritten to work on Python3 as well as Jinja.
