 <h2>How We Plan Releases</h2>

 <p>Subversion uses a compromise between time-driven and feature-driven
 release planning.  We schedule the next release for an approximate
 date (very approximate), and make sure it contains one or more new
 features or other significant differentiators, but we don't say
 exactly what those new features will be.  This is because we're always
 working on several things at once, and we want to give each new
 feature time to mature.  Especially given the decentralized nature of
 open-source development, we're wary of forcing technical discussions
 to premature consensus.  At the same time, it's good for the project
 to have regular releases, so we try to keep to a schedule and to
 have <i>something</i> ready to roll out when the release date comes
 along.</p>

 <p>In this context, "release" means an increment of the minor release
 number, which is the middle number in our three-component system.
 Thus, 1.2.0, 1.3.0, and 1.4.0 are successive minor releases in the
 "1.x" line, whereas 1.1.1, 1.1.2, and 1.1.3 are successive patch
 (bugfix) releases in the "1.1.x" line.  We don't schedule patch
 releases far in advance, we just put them out when we feel enough
 bugfixes have accumulated to warrant it.  Major new releases, such as
 Subversion 2.0, will probably be done much like the minor releases,
 just with more planning around the exact features.  For more
 information about Subversion's release numbering and compatibility
 policies, see the section entitled <i>"Release numbering,
 compatibility, and deprecation"</i> in the
 <a href="hacking.html">Hacker's Guide to Subversion</a>.</p>

 </div>

 <div class="h2" id="upcoming-features" title="upcoming-features">
 <h2>Upcoming Features</h2>

 <p>We try to have at least one or two new features under active
 development at any given time, but we generally don't rush a feature
 to get it into a release.  The flexibly time-driven model <a
 href="#release-planning">described above</a> means there's never a
 long wait between releases, which in turn means less pressure to cram
 a feature into whatever release happens to be going out the door next.
 Our main source of ideas is our users: we watch the <a
 href="mailto:users@subversion.tigris.org"
 >users@subversion.tigris.org</a> mailing list, the <a
 href="irc://irc.freenode.net/#svn">#svn IRC channel</a>, and the <a
 href="project_issues.html">issue tracker</a> to see what people are
 saying, and base our priorities on that, though we may sometimes grab
 low-hanging fruit along the way.</p>

 <p>Below are new features currently under discussion and design, as
 extracted from the ever-changing consensus of the Subversion developer
 community.  Because this is a volunteer open-source project, it's hard
 to predict exact dates or timetables for these new features.  At most,
 we can express dependencies and predict the order in which things will
 be worked on.  The best way to track development is to <a
 href="/servlets/ProjectMailingListList">subscribe</a> to the
 development mailing list, <a href="mailto:dev@subversion.tigris.org"
 >dev@subversion.tigris.org</a>.</p>
