<h1>What’s New in Bazaar 2.1?<a class="headerlink" href="#what-s-new-in-bazaar-2-1" title="Permalink to this headline">¶</a></h1>
<p>This document outlines the major improvements in Bazaar 2.1
vs Bazaar 2.0. As well as summarizing improvements made to
the core product, it highlights enhancements within the broader
Bazaar world of potential interest to those upgrading.</p>
<p>Bazaar 2.1.0 marks the start of our second long-term-stable series.
This series will be supported with bug fixes for the next 12 months.
All users are encouraged to upgrade from the 2.0.x stable series.</p>
<div class="section" id="better-efficiency">
<h2>Better efficiency<a class="headerlink" href="#better-efficiency" title="Permalink to this headline">¶</a></h2>
<p>Many operations now consume less memory. Several operations are
also faster including branching, logging merged revisions and
upgrading from pre-2a to 2a format.</p>
</div>
<div class="section" id="new-command-options">
<h2>New command options<a class="headerlink" href="#new-command-options" title="Permalink to this headline">¶</a></h2>
<p>Several commands have new options. These include:</p>
<table border="1" class="docutils">
<colgroup>
<col width="17%" />
<col width="22%" />
<col width="60%" />
</colgroup>
<thead valign="bottom">
<tr class="row-odd"><th class="head">Command</th>
<th class="head">Option</th>
<th class="head">Description</th>
</tr>
</thead>
<tbody valign="top">
<tr class="row-even"><td>branch</td>
<td>bind</td>
<td>Bind to the source location</td>
</tr>
<tr class="row-odd"><td>commit</td>
<td>commit-time</td>
<td>Give an explicit commit timestamp</td>
</tr>
<tr class="row-even"><td>switch</td>
<td>revision</td>
<td>Switch to a particular revision</td>
</tr>
<tr class="row-odd"><td>unshelve</td>
<td>keep</td>
<td>Apply changes but don’t delete them</td>
</tr>
<tr class="row-even"><td>unshelve</td>
<td>preview</td>
<td>Show the diff that would result from
unshelving</td>
</tr>
<tr class="row-odd"><td>update</td>
<td>revision</td>
<td>Update to a particular revision</td>
</tr>
</tbody>
</table>
<p>Other command improvements include:</p>
<ul class="simple">
<li>A <a class="reference internal" href="../user-reference/shelve-help.html"><em>shelve</em></a> editor can be defined to provide shelf functionality at
a granularity finer than per-patch hunk.</li>
<li><a class="reference internal" href="../user-reference/send-help.html"><em>send</em></a> send now supports the OS X Mail application.</li>
</ul>
<p>See the help for the commands above for further details.</p>
</div>
<div class="section" id="per-file-merge-hooks">
<h2>Per-file merge hooks<a class="headerlink" href="#per-file-merge-hooks" title="Permalink to this headline">¶</a></h2>
<p>Hooks can now be defined for smart merging of selected file types.
This enables easier merging of ChangeLogs, Release Notes and other
file that frequently conflict.</p>
</div>
<div class="section" id="dwim-revision-identifiers">
<h2>DWIM revision identifiers<a class="headerlink" href="#dwim-revision-identifiers" title="Permalink to this headline">¶</a></h2>
<p>Revision identifiers can now be given in a <em>Do-What-I-Mean</em> style.
For example, you can now just give a tag (instead of saying <tt class="docutils literal"><span class="pre">tag:xxx</span></tt>)
or just say <tt class="docutils literal"><span class="pre">today</span></tt> (instead of saying <tt class="docutils literal"><span class="pre">date:today</span></tt>). Prefixes
are now only required if the revision spec could be ambiguous.</p>
</div>
<div class="section" id="launchpad-compatibility">
<h2>Launchpad compatibility<a class="headerlink" href="#launchpad-compatibility" title="Permalink to this headline">¶</a></h2>
<p>Launchpad has <a class="reference external" href="http://blog.launchpad.net/general/edge-is-deprecated">announced</a> that the
<tt class="docutils literal"><span class="pre">edge.launchpad.net</span></tt> instance is deprecated and may be shut down in the
future . Bazaar has therefore been updated in this release to talk to the main
(<tt class="docutils literal"><span class="pre">launchpad.net</span></tt>) servers, rather than the <tt class="docutils literal"><span class="pre">edge</span></tt> ones (the same code is
running on both servers during the interim).</p>
</div>
<div class="section" id="new-ignore-patterns">
<h2>New ignore patterns<a class="headerlink" href="#new-ignore-patterns" title="Permalink to this headline">¶</a></h2>
<p>Patterns prefixed with <tt class="docutils literal"><span class="pre">!</span></tt> are exceptions to ignore patterns and
take precedence over regular ignores. Such exceptions are used to
specify files that should be versioned which would otherwise be
ignored. Patterns prefixed with <tt class="docutils literal"><span class="pre">!!</span></tt> act as regular ignore patterns,
but have highest precedence, even over the <tt class="docutils literal"><span class="pre">!</span></tt> exception patterns.</p>
</div>
<div class="section" id="smart-server-home-directory-support">
<h2>Smart server home directory support<a class="headerlink" href="#smart-server-home-directory-support" title="Permalink to this headline">¶</a></h2>
<p><tt class="docutils literal"><span class="pre">bzr+ssh</span></tt> and <tt class="docutils literal"><span class="pre">bzr</span></tt> paths can now be relative to home directories
specified in the URL. Paths starting with a path segment of <tt class="docutils literal"><span class="pre">~</span></tt> are
relative to the home directory of the user running the server, and paths
starting with <tt class="docutils literal"><span class="pre">~user</span></tt> are relative to the home directory of the named
user. For example, for a user “bob” with a home directory of
<tt class="docutils literal"><span class="pre">/home/bob</span></tt>, these URLs are all equivalent:</p>
<ul class="simple">
<li><tt class="docutils literal"><span class="pre">bzr+ssh://bob@host/~/repo</span></tt></li>
<li><tt class="docutils literal"><span class="pre">bzr+ssh://bob@host/~bob/repo</span></tt></li>
<li><tt class="docutils literal"><span class="pre">bzr+ssh://bob@host/home/bob/repo</span></tt></li>
</ul>
<p>If <tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">serve</span></tt> was invoked with a <tt class="docutils literal"><span class="pre">--directory</span></tt> argument, then no
home directories outside that directory will be accessible via this
method.</p>
<p>This is a feature of <tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">serve</span></tt>, so pre-2.1 clients will
automatically benefit from this feature when <tt class="docutils literal"><span class="pre">bzr</span></tt> on the server is
upgraded.</p>
</div>
<div class="section" id="generalized-glob-support-on-windows">
<h2>Generalized glob support on Windows<a class="headerlink" href="#generalized-glob-support-on-windows" title="Permalink to this headline">¶</a></h2>
<p>On Windows, glob expansion is now handled in a universal way across
all commands. In previous versions, it was explicitly handed by just
a few commands, e.g. <tt class="docutils literal"><span class="pre">add</span></tt>. A side effect of this change is that
patterns now need to be quoted when passed to the <tt class="docutils literal"><span class="pre">ignore</span></tt> command,
e.g. <tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">ignore</span> <span class="pre">*.foo</span></tt> now needs to be given as <tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">ignore</span> <span class="pre">"*.foo"</span></tt>.</p>
</div>
<div class="section" id="improved-git-and-mercurial-interoperability">
<h2>Improved Git and Mercurial interoperability<a class="headerlink" href="#improved-git-and-mercurial-interoperability" title="Permalink to this headline">¶</a></h2>
<p>Many improvements have been made to the <a class="reference external" href="http://doc.bazaar.canonical.com/plugins/en/git-plugin.html">git</a> and <a class="reference external" href="http://doc.bazaar.canonical.com/plugins/en/hg-plugin.html">hg</a> plugins.
With these plugins installed, most Git and Mercurial repositories
can now be read by standard Bazaar clients. Changes can also
be written back via the dpush command.</p>
</div>
<div class="section" id="metaprojects">
<h2>Metaprojects<a class="headerlink" href="#metaprojects" title="Permalink to this headline">¶</a></h2>
<p>New plugins are available for constructing larger projects
from smaller ones. These include:</p>
<ul class="simple">
<li><a class="reference external" href="http://doc.bazaar.canonical.com/plugins/en/builder-plugin.html">builder</a> - construction of a branch using recipes</li>
<li><a class="reference external" href="http://doc.bazaar.canonical.com/plugins/en/externals-plugin.html">externals</a> - Subversion-style external branches</li>
</ul>
<div class="admonition note">
<p class="first admonition-title">Note</p>
<p class="last">The builder plugin has been designed to complement the <a class="reference external" href="http://doc.bazaar.canonical.com/plugins/en/builddeb-plugin.html">builddeb</a>
plugin to streamline Debian source package management. It may also
be useful for building test images for a QA team or disk images
for installers, say.</p>
</div>
</div>
<div class="section" id="colocated-branch-workspaces">
<h2>Colocated branch workspaces<a class="headerlink" href="#colocated-branch-workspaces" title="Permalink to this headline">¶</a></h2>
<p>A colocated workspace is one where a single working tree is used
across one or more branches managed at that same location. This
is now supported by the new <a class="reference external" href="http://doc.bazaar.canonical.com/plugins/en/colo-plugin.html">colo</a> plugin and by Bazaar Explorer.</p>
</div>
<div class="section" id="better-documentation">
<h2>Better documentation<a class="headerlink" href="#better-documentation" title="Permalink to this headline">¶</a></h2>
<p>A <a class="reference internal" href="../admin-guide/index.html"><em>Bazaar System Administrator’s Guide</em></a> covering topics such as setting up servers,
security, backups and email integration has been added.</p>
<p>A large number of documentation bugs have been fixed, clarifying
numerous issues and filling in some missing holes.</p>
<p>The <a class="reference internal" href="../user-reference/index.html"><em>Bazaar User Reference</em></a>
has been organized into topics making it easier to
navigate through and print selected sections of.</p>
<p>To assist users migrating from other tools, a
<a class="reference external" href="http://doc.bazaar.canonical.com/migration/en/survival/index.html">Survival Guide</a>
has been published explaining Bazaar to users of other tools in terms they
already know. Sections are provided for existing users of
CVS, Subversion, ClearCase, Perforce, Visual SourceSafe, Git, Mercurial,
Darcs and Monotone.</p>
<p>Selected documents have also been translated to Japanese.</p>
</div>
<div class="section" id="enhanced-gui-clients">
<h2>Enhanced GUI clients<a class="headerlink" href="#enhanced-gui-clients" title="Permalink to this headline">¶</a></h2>
<p>Numerous enhancements have been made to most of our GUIs including
Bazaar Explorer, TortoiseBZR and the QBzr-Eclipse add-on. These
applications all build on top of improvements made to QBzr. Bzr-gtk
has also been improved.</p>
<p>Bazaar Explorer has over a dozen new features including smart toolbars,
support for all bzr commands (including those in plugins),
a better working tree browser and a submit delta report showing the
cumulative effect of a series of commits.
See <a class="reference external" href="http://doc.bazaar.canonical.com/explorer/en/whats-new/whats-new-in-1.0.html">What’s New in Bazaar Explorer 1.0?</a>
