<h3>Compatibility Breaks<a class="headerlink" href="#compatibility-breaks" title="Permalink to this headline">¶</a></h3>
<ul class="simple">
<li>A previously disabled code path to accelerate getting configuration
settings from a smart server has been reinstated. We think this <em>may</em>
cause a incompatibility with servers older than bzr 0.15. We intend
to issue a point release to address this if it turns out to be a
problem. (Robert Collins, Andrew Bennetts)</li>
<li>bzr no longer autodetects nested trees as ‘tree-references’. They
must now be explicitly added tree references. At the commandline, use
join –reference instead of add. (Aaron Bentley)</li>
<li>The <code class="docutils literal notranslate"><span class="pre">--long</span></code> log format (the default) no longer shows merged
revisions implicitly, making it consistent with the <code class="docutils literal notranslate"><span class="pre">short</span></code> and
<code class="docutils literal notranslate"><span class="pre">line</span></code> log formats. To see merged revisions for just a given
revision, use <code class="docutils literal notranslate"><span class="pre">bzr</span> <span class="pre">log</span> <span class="pre">-n0</span> <span class="pre">-rX</span></code>. To see every merged revision,
use <code class="docutils literal notranslate"><span class="pre">bzr</span> <span class="pre">log</span> <span class="pre">-n0</span></code>. (Ian Clatworthy)</li>

<h3>New Features<a class="headerlink" href="#new-features" title="Permalink to this headline">¶</a></h3>
<ul class="simple">
<li>New formats <code class="docutils literal notranslate"><span class="pre">1.14</span></code> and <code class="docutils literal notranslate"><span class="pre">1.14-rich-root</span></code> supporting End-Of-Line
(EOL) conversions, keyword templating (via the bzr-keywords plugin)
and generic content filtering. These formats replace the experimental
<code class="docutils literal notranslate"><span class="pre">development-wt5</span></code> and <code class="docutils literal notranslate"><span class="pre">development-wt5-rich-root</span></code> formats
respectively, but have support for filtered views disabled.
(Ian Clatworthy)</li>
<li>New <code class="docutils literal notranslate"><span class="pre">mv</span> <span class="pre">--auto</span></code> option recognizes renames after they occur.
(Aaron Bentley)</li>
<li><code class="docutils literal notranslate"><span class="pre">bzr</span></code> can now get passwords from stdin without requiring a controlling
terminal (i.e. by redirecting stdin). (Vincent Ladeuil)</li>
<li><code class="docutils literal notranslate"><span class="pre">bzr</span> <span class="pre">log</span></code> now supports filtering of multiple files and directories
and will show changes that touch any of them. Furthermore,
directory filtering now shows the changes to any children of that
directory, not just the directory object itself.
(Ian Clatworthy, #97715)</li>
<li><code class="docutils literal notranslate"><span class="pre">bzr</span> <span class="pre">shelve</span></code> can now apply changes without storing anything on the
shelf, via the new –destroy option. (Aaron Bentley)</li>
<li><code class="docutils literal notranslate"><span class="pre">bzr</span> <span class="pre">send</span></code> now accepts –body to specify an initial message body.
(Aaron bentley)</li>
<li><code class="docutils literal notranslate"><span class="pre">bzr</span> <span class="pre">xxx</span> <span class="pre">--usage</span></code> where xxx is a command now shows a usage
message and the options without the descriptive help sections
(like Description and Examples). A message is also given
explaining how to see the complete help, i.e. <code class="docutils literal notranslate"><span class="pre">bzr</span> <span class="pre">help</span> <span class="pre">xxx</span></code>.
(Ian Clatworthy)</li>
<li>Content filters can now be used to provide custom conversion
between the canonical format of content (i.e. as stored) and
the convenience format of content (i.e. as created in working
trees). See <code class="docutils literal notranslate"><span class="pre">bzr</span> <span class="pre">help</span> <span class="pre">content-filters</span></code> for further details.
(Ian Clatworthy, Alexander Belchenko)</li>
<li>End-of-line conversion is now supported for formats supporting
content filtering. See <code class="docutils literal notranslate"><span class="pre">bzr</span> <span class="pre">help</span> <span class="pre">eol</span></code> for details.

<div class="section" id="improvements">
<h3>Improvements<a class="headerlink" href="#improvements" title="Permalink to this headline">¶</a></h3>
<ul class="simple">
<li>A new format name alias <code class="docutils literal notranslate"><span class="pre">default-rich-root</span></code> has been added and
points at the closest relative of the default format that supports
rich roots. (Jelmer Vernooij, #338061)</li>
<li>Branching from a stacked branch using <code class="docutils literal notranslate"><span class="pre">bzr*://</span></code> will now stream
the data when the target repository does not need topological
ordering, reducing round trips and network overhead. This uses the
existing smart server methods added in 1.13, so will work on any
1.13 or newer server. (Robert Collins, Andrew Bennetts)</li>
<li><code class="docutils literal notranslate"><span class="pre">bzr</span> <span class="pre">cat</span></code> and <code class="docutils literal notranslate"><span class="pre">bzr</span> <span class="pre">export</span></code> now supports a <code class="docutils literal notranslate"><span class="pre">--filters</span></code> option
that displays/saves the content after content filters are applied.
(Ian Clatworthy)</li>
<li><code class="docutils literal notranslate"><span class="pre">bzr</span> <span class="pre">ignore</span></code> gives a more informative message when existing
version controlled files match the ignore pattern. (Neil
Martinsen-Burrell, #248895)</li>
<li><code class="docutils literal notranslate"><span class="pre">bzr</span> <span class="pre">log</span></code> now has <code class="docutils literal notranslate"><span class="pre">--include-merges</span></code> as an alias for <code class="docutils literal notranslate"><span class="pre">--levels</span> <span class="pre">0</span></code>.
(Ian Clatworthy)</li>
<li><code class="docutils literal notranslate"><span class="pre">bzr</span> <span class="pre">send</span></code> is faster on repositories with deep histories.
(Ian Clatworthy)</li>
<li>IPv6 literals are accepted in URLs.
(stlman, Martin Pool, Jelmer Vernooij, #165014)</li>
<li>Progress bars now show the rate of network activity for
<code class="docutils literal notranslate"><span class="pre">bzr+ssh://</span></code> and <code class="docutils literal notranslate"><span class="pre">bzr://</span></code> connections. (Andrew Bennetts)</li>
<li>Prompt for user names if they are not in the configuration.
(Jelmer Vernooij, #256612)</li>
<li>Pushing to a stacked pack-format branch on a 1.12 or older smart server
now takes many less round trips. (Andrew Bennetts, Robert Collins,
#294479)</li>
<li>Streaming push can be done to older repository formats. This is
implemented using a new <code class="docutils literal notranslate"><span class="pre">Repository.insert_stream_locked</span></code> RPC.
(Andrew Bennetts, Robert Collins)</li>
<li>The “ignoring files outside view: ..” message has been re-worded
to “Ignoring files outside view. View is ..” to reduce confusion
about what was being considered and what was being ignored.
(Ian Clatworthy)</li>
<li>The <code class="docutils literal notranslate"><span class="pre">long</span></code> log formatter now shows [merge] indicators. If
only one level of revisions is displayed and merges are found,
the <code class="docutils literal notranslate"><span class="pre">long</span></code> and <code class="docutils literal notranslate"><span class="pre">short</span></code> log formatters now tell the user
how to see the hidden merged revisions. (Ian Clatworthy)</li>
<li>The <code class="docutils literal notranslate"><span class="pre">brisbane-core</span></code> project has delivered its beta format
<code class="docutils literal notranslate"><span class="pre">development6-rich-root</span></code>. This format is suitable for judicious
testing by early adopters. In particular if you are benchmarking bzr
performance please be sure to test using this format. At this stage
more information is best obtained by contacting the Bazaar mailing list
or IRC channel if you are interested in using this format. We will make
end user documentation available closer to blessing the format as
production ready. (Robert Collins, John Arbash Meinel, Ian Clatworthy,
Vincent Ladeuil, Andrew Bennetts, Martin Pool)</li>
<li>Tildes are no longer escaped. No more %7Euser/project/branch!

<h3>Bug Fixes<a class="headerlink" href="#bug-fixes" title="Permalink to this headline">¶</a></h3>
<ul class="simple">
<li>Pushing a new stacked branch will also push the parent inventories for
revisions at the stacking boundary. This makes sure that the stacked
branch has enough data to calculate inventory deltas for all of its
revisions (without requiring the fallback branch). This avoids
“‘AbsentContentFactory’ object has no attribute ‘get_bytes_as’” errors
when fetching the stacked branch from a 1.13 (or later) smart server.
This partially fixes #354036. (Andrew Bennetts, Robert Collins)</li>
<li>End-Of-Line content filters are now loaded correctly.
(Ian Clatworthy, Brian de Alwis, #355280)</li>
<li>Authentication plugins now receive all the parameters from the request
itself (aka host, port, realm, path, etc). Previously, only the
authentication section name, username and encoded password were
provided. (Jean-Francois Roy)</li>
<li>bzr gives a better message if an invalid regexp is passed to <code class="docutils literal notranslate"><span class="pre">bzr</span> <span class="pre">log</span>
<span class="pre">-m</span></code>. (Anne Mohsen, Martin Pool)</li>
<li><code class="docutils literal notranslate"><span class="pre">bzr</span> <span class="pre">split</span></code> now says “See also: join” (Aaron Bentley, #335015)</li>
<li><code class="docutils literal notranslate"><span class="pre">bzr</span> <span class="pre">version-info</span></code> now works in empty branches. (Jelmer Vernooij,
#313028)</li>
<li>Fix “is not a stackable format” error when pushing a
stackable-format branch with an unstackable-format repository to a
destination with a default stacking policy. (Andrew Bennetts)</li>
<li>Fixed incorrect “Source format does not support stacking” warning
when pushing to a smart server. (Andrew Bennetts, #334114)</li>
<li>Fix ‘make check-dist-tarball’ failure by converting paths to unicode when
needed. (Vincent Ladeuil, #355454)</li>
<li>Fixed “Specified file ‘x/y/z’ is outside current view: ” occurring
on <code class="docutils literal notranslate"><span class="pre">bzr</span> <span class="pre">add</span> <span class="pre">x/y/z</span></code> in formats supporting views when no view is
defined. (Ian Clatworthy, #344708)</li>
<li>It is no longer possible to fetch between repositories while the
target repository is in a write group. This prevents race conditions
that prevent the use of RPC’s to perform fetch, and thus allows
optimising more operations. (Robert Collins, Andrew Bennetts)</li>
<li><code class="docutils literal notranslate"><span class="pre">merge</span> <span class="pre">--force</span></code> works again. (Robert Collins, #342105)</li>
<li>No more warnings are issued about <code class="docutils literal notranslate"><span class="pre">sha</span></code> being deprecated under python-2.6.
(Vincent Ladeuil, #346593)</li>
<li>Pushing a new branch to a server that has a stacking policy will now
upgrade from the local branch format when the stacking policy points at
a branch which is itself stackable, because we know the client can read
both branches, we know that the trunk for the project can be read too,
so the upgrade will not inconvenience users. (Robert Collins, #345169)</li>
<li>Pushing a new stacked branch will also push the parent inventories for
revisions at the stacking boundary. This makes sure that the stacked
branch has enough data to calculate inventory deltas for all of its
revisions (without requiring the fallback branch). This avoids
“‘AbsentContentFactory’ object has no attribute ‘get_bytes_as’” errors
when fetching the stacked branch from a 1.13 (or later) smart server.
This partially fixes #354036. (Andrew Bennetts, Robert Collins)</li>
<li>The full test suite is passing again on OSX. Several minor issues (mostly
test related) have been fixed. (Vincent Ladeuil, #355273).</li>
<li>The GNU Changelog formatter is slightly improved in the case where
the delta is empty, and now correctly claims not to support tags.
(Andrea Bolognani)</li>
<li>Shelve can now shelve changes to a symlink target.
(James Westby, #341558)</li>
<li>The help for the <code class="docutils literal notranslate"><span class="pre">info</span></code> command has been corrected.
(Ian Clatworthy, #351931)</li>
<li>Upgrade will now use a sensible default format if the source repository
uses rich roots. (Jelmer Vernooij, #252908)</li>

<h3>API Changes<a class="headerlink" href="#api-changes" title="Permalink to this headline">¶</a></h3>
<ul class="simple">
<li>APIs deprecated in 1.6 and previous versions of bzr are now removed.
(Martin Pool)</li>
<li><code class="docutils literal notranslate"><span class="pre">CommitReporter</span></code> is no longer called with <code class="docutils literal notranslate"><span class="pre">unchanged</span></code> status during
commit - this was a full-tree overhead that bzr no longer performs.
(Robert Collins)</li>
<li>New abstract <code class="docutils literal notranslate"><span class="pre">UIFactory</span></code> method <code class="docutils literal notranslate"><span class="pre">get_username</span></code> which will be called to
obtain the username to use when connecting to remote machines.
(Jelmer Vernooij)</li>
<li>New API <code class="docutils literal notranslate"><span class="pre">Inventory.filter()</span></code> added that filters an inventory by
a set of file-ids so that only those fileids, their parents and
their children are included. (Ian Clatworthy)</li>
<li>New sort order for <code class="docutils literal notranslate"><span class="pre">get_record_stream</span></code> <code class="docutils literal notranslate"><span class="pre">groupcompress</span></code> which
sorts optimally for use with groupcompress compressors. (John Arbash
Meinel, Robert Collins)</li>
<li>Repository APIs <code class="docutils literal notranslate"><span class="pre">get_deltas_for_revisions()</span></code> and
<code class="docutils literal notranslate"><span class="pre">get_revision_delta()</span></code> now support an optional <code class="docutils literal notranslate"><span class="pre">specific_fileids</span></code>
parameter. If provided, the deltas are filtered so that only those
file-ids, their parents and their children are included.
(Ian Clatworthy)</li>
<li>The <code class="docutils literal notranslate"><span class="pre">get_credentials</span></code> and <code class="docutils literal notranslate"><span class="pre">set_credentials</span></code> methods of

(Jean-Francois Roy)</li>
<li>The <code class="docutils literal notranslate"><span class="pre">pb</span></code> argument to <code class="docutils literal notranslate"><span class="pre">fetch()</span></code> is deprecated.
(Martin Pool)</li>
<li>The <code class="docutils literal notranslate"><span class="pre">Serializer</span></code> class and the serializer <code class="docutils literal notranslate"><span class="pre">format</span> <span class="pre">registry</span></code> have moved
from <code class="docutils literal notranslate"><span class="pre">bzrlib.xml_serializer</span></code> to <code class="docutils literal notranslate"><span class="pre">bzrlib.serializer</span></code>. (Jelmer Vernooij)</li>
<li>The smart server jail now hooks into BzrDir.open to prevent any BzrDir
that is not inside the backing transport from being opened. See the
module documentation for <code class="docutils literal notranslate"><span class="pre">bzrlib.smart.request</span></code> for details.
(Andrew Bennetts, Robert Collins)</li>
<li><code class="docutils literal notranslate"><span class="pre">Tree.get_symlink_target</span></code> now always returns a unicode string result

forget to upcall when overriding <code class="docutils literal notranslate"><span class="pre">setUp</span></code> and <code class="docutils literal notranslate"><span class="pre">tearDown</span></code>. Those
faulty tests were not properly isolated.

<li>Fix test_msgeditor.MsgEditorTest test isolation.
(Vincent Ladeuil, #347130)</li>
<li><code class="docutils literal notranslate"><span class="pre">medusa</span></code> is not used anymore as an FTP test server starting with
python2.6. A new FTP test server based on <code class="docutils literal notranslate"><span class="pre">pyftplib</span></code> can be used

(Robert Collins, John Arbash Meinel, Vincent Ladeuil)</li>
<li>Added <code class="docutils literal notranslate"><span class="pre">bzrlib.chk_map</span></code> for fast, trie-based storage of tuple to string
maps. (Robert Collins, John Arbash Meinel, Vincent Ladeuil)</li>
<li>Added <code class="docutils literal notranslate"><span class="pre">bzrlib.inventory_delta</span></code> module. This will be used for
serializing and deserializing inventory deltas for more efficient
streaming on the network. (Robert Collins, Andrew Bennetts)</li>
<li><code class="docutils literal notranslate"><span class="pre">Branch._get_config</span></code> has been added, which splits out access to the
specific config file from the branch. This is used to let RemoteBranch
avoid constructing real branch objects to access configuration settings.
(Robert Collins, Andrew Bennetts)</li>
<li><code class="docutils literal notranslate"><span class="pre">Branch</span></code> now implements <code class="docutils literal notranslate"><span class="pre">set_stacked_on_url</span></code> in the base class as
the implementation is generic and should impact foreign formats. This

<li><code class="docutils literal notranslate"><span class="pre">CommitBuilder</span></code> has a new method, <code class="docutils literal notranslate"><span class="pre">record_iter_changes</span></code> which works
in terms of an iter_changes iterator rather than full tree scanning.

<li><code class="docutils literal notranslate"><span class="pre">DirState</span></code> can now be passed a custom <code class="docutils literal notranslate"><span class="pre">SHA1Provider</span></code> object
enabling it to store the SHA1 and stat of the canonical (post

<li>New <code class="docutils literal notranslate"><span class="pre">assertLength</span></code> method based on one Martin has squirreled away
somewhere. (Robert Collins, Martin Pool)</li>
<li>New hook <code class="docutils literal notranslate"><span class="pre">BzrDir.pre_open</span></code> which runs before opening <code class="docutils literal notranslate"><span class="pre">BzrDir</span></code>
objects, allowing better enforcement of the smart server jail when
dealing with stacked branches. (Robert Collins, Andrew Bennetts)</li>
<li>New hook <code class="docutils literal notranslate"><span class="pre">RioVersionInfoBuilder.revision</span></code>, allowing extra entries
to be added to the stanza that is printed for a particular revision.
(Jelmer Vernooij)</li>
<li>New repository method <code class="docutils literal notranslate"><span class="pre">refresh_data</span></code> to cause any repository to
make visible data inserted into the repository by a smart server
fetch operation. (Robert Collins, Andrew Bennetts)</li>
<li><code class="docutils literal notranslate"><span class="pre">register_filter_stack_map</span></code> now takes an optional fallback parameter,
a callable to invoke if a preference has a value not in the map
of filter stacks. This enhancement allows, for example, bzr-svn to
handle existing svn properties that define a list of keywords to be
expanded. (Ian Clatworthy)</li>
<li><code class="docutils literal notranslate"><span class="pre">RemoteBranchConfig</span></code> will use a new verb <code class="docutils literal notranslate"><span class="pre">Branch.set_config_option</span></code>
to write config settings to smart servers that support this, saving
5 round trips on the stacked streaming acceptance test.
(Robert Collins, Andrew Bennetts)</li>
<li><code class="docutils literal notranslate"><span class="pre">RemoteBranch</span></code> now provides <code class="docutils literal notranslate"><span class="pre">_get_config</span></code> for access to just the
branch specific configuration from a remote server, which uses the
already existing <code class="docutils literal notranslate"><span class="pre">Branch.get_config_file</span></code> smart verb.
(Robert Collins, Andrew Bennetts)</li>
<li><code class="docutils literal notranslate"><span class="pre">RemoteRepository</span></code> will now negatively cache missing revisions during
<code class="docutils literal notranslate"><span class="pre">get_parent_map</span></code> while read-locked. Write-locks are unaffected.
(Robert Collins, Andrew Bennetts)</li>
<li>Removed <code class="docutils literal notranslate"><span class="pre">InterRemoteToOther</span></code>, <code class="docutils literal notranslate"><span class="pre">InterOtherToRemote</span></code> and
<code class="docutils literal notranslate"><span class="pre">InterPackToRemotePack</span></code> classes, as they are now unnecessary.
(Andrew Bennetts)</li>
<li><code class="docutils literal notranslate"><span class="pre">RepositoryFormat</span></code> as a new attribute <code class="docutils literal notranslate"><span class="pre">fast_deltas</span></code> to indicate
whether the repository can efficiently generate deltas between trees
regardless of tree size. (Robert Collins)</li>
<li><code class="docutils literal notranslate"><span class="pre">Repository.iter_files_bytes()</span></code> now properly returns an “iterable of
byte strings” (aka ‘chunked’) for the content. It previously was
returning a plain string, which worked, but performed very poorly when
building a working tree (file.writelines(str) is very inefficient). This
can have a large effect on <code class="docutils literal notranslate"><span class="pre">bzr</span> <span class="pre">checkout</span></code> times. (John Arbash Meinel)</li>
<li>selftest now supports a –parallel option, with values of ‘fork’ or
‘subprocess’ to run the test suite in parallel. Currently only Linux
machines work, other platforms need patches submitted. (Robert Collins,
Vincent Ladeuil)</li>
<li><code class="docutils literal notranslate"><span class="pre">tests.run_suite</span></code> has a new parameter <code class="docutils literal notranslate"><span class="pre">suite_decorators</span></code>, a list of
callables to use to decorate the test suite. Such decorators can add or
remove tests, or even remote the test suite to another machine if
desired. (Robert Collins)</li>
<li>The smart server verb <code class="docutils literal notranslate"><span class="pre">Repository.get_parent_map</span></code> can now include
information about ghosts when the special revision <code class="docutils literal notranslate"><span class="pre">include-missing:</span></code>
is in the requested parents map list. With this flag, ghosts are
included as <code class="docutils literal notranslate"><span class="pre">missing:REVISION_ID</span></code>. (Robert Collins, Andrew Bennetts)</li>
<li><code class="docutils literal notranslate"><span class="pre">_walk_to_common_revisions</span></code> will now batch up at least 50
revisions before calling <code class="docutils literal notranslate"><span class="pre">get_parent_map</span></code> on the target,
regardless of <code class="docutils literal notranslate"><span class="pre">InterRepository</span></code>.
