<h3>Improvements<a class="headerlink" href="#improvements" title="Permalink to this headline">¶</a></h3>
<ul class="simple">
<li>Documentation is now organized into multiple directories with a level
added for different languages or locales. Added the Mini Tutorial
and Quick Start Summary (en) documents from the Wiki, improving the
content and readability of the former. Formatted NEWS as Release Notes
complete with a Table of Conents, one heading per release. Moved the
Developer Guide into the main document catalog and provided a link
from the developer document catalog back to the main one.

<h3>Bugfixes<a class="headerlink" href="#bugfixes" title="Permalink to this headline">¶</a></h3>
<ul class="simple">
<li><code class="docutils literal notranslate"><span class="pre">bzr</span> <span class="pre">init</span></code> should connect to the remote location one time only. We
have been connecting several times because we forget to pass around the
Transport object. This modifies <code class="docutils literal notranslate"><span class="pre">BzrDir.create_branch_convenience</span></code>,
so that we can give it the Transport we already have.
(John Arbash Meinel, Vincent Ladeuil, #111702)</li>
<li>Get rid of SFTP connection cache (get rid of the FTP one too).
(Vincent Ladeuil, #43731)</li>
<li>bzr branch {local|remote} remote don’t try to create a working tree
anymore.
(Vincent Ladeuil, #112173)</li>
<li>All identified multiple connections for a single bzr command have been
fixed. See bzrlib/tests/commands directory.
(Vincent Ladeuil)</li>
<li><code class="docutils literal notranslate"><span class="pre">bzr</span> <span class="pre">rm</span></code> now does not insist on <code class="docutils literal notranslate"><span class="pre">--force</span></code> to delete files that
have been renamed but not otherwise modified. (Marius Kruger,
#111664)</li>
<li><code class="docutils literal notranslate"><span class="pre">bzr</span> <span class="pre">selftest</span> <span class="pre">--bench</span></code> no longer emits deprecation warnings
(Lukáš Lalinský)</li>
<li><code class="docutils literal notranslate"><span class="pre">bzr</span> <span class="pre">status</span></code> now honours FILE parameters for conflict lists
(Aaron Bentley, #127606)</li>
<li><code class="docutils literal notranslate"><span class="pre">bzr</span> <span class="pre">checkout</span></code> now honours -r when reconstituting a working tree.
It also honours -r 0. (Aaron Bentley, #127708)</li>
<li><code class="docutils literal notranslate"><span class="pre">bzr</span> <span class="pre">add</span> <span class="pre">*</span></code> no more fails on Windows if working tree contains
non-ascii file names. (Kuno Meyer, #127361)</li>
<li>allow <code class="docutils literal notranslate"><span class="pre">easy_install</span> <span class="pre">bzr</span></code> runs without fatal errors.
(Alexander Belchenko, #125521)</li>
<li>Graph._filter_candidate_lca does not raise KeyError if a candidate
is eliminated just before it would normally be examined. (Aaron Bentley)</li>
<li>SMTP connection failures produce a nice message, not a traceback.
(Aaron Bentley)</li>
</ul>
</div>
<div class="section" id="id1">
<h3>Improvements<a class="headerlink" href="#id1" title="Permalink to this headline">¶</a></h3>
<ul class="simple">
<li>Don’t show “dots” progress indicators when run non-interactively, such
as from cron. (Martin Pool)</li>
<li><code class="docutils literal notranslate"><span class="pre">info</span></code> now formats locations more nicely and lists “submit” and
“public” branches (Aaron Bentley)</li>
<li>New <code class="docutils literal notranslate"><span class="pre">pack</span></code> command that will trigger database compression within
the repository (Robert Collins)</li>
<li>Implement <code class="docutils literal notranslate"><span class="pre">_KnitIndex._load_data</span></code> in a pyrex extension. The pyrex
version is approximately 2-3x faster at parsing a <code class="docutils literal notranslate"><span class="pre">.kndx</span></code> file.
Which yields a measurable improvement for commands which have to
read from the repository, such as a 1s => 0.75s improvement in
<code class="docutils literal notranslate"><span class="pre">bzr</span> <span class="pre">diff</span></code> when there are changes to be shown. (John Arbash Meinel)</li>
<li>Merge is now faster. Depending on the scenario, it can be more than 2x
faster. (Aaron Bentley)</li>
<li>Give a clearer warning, and allow <code class="docutils literal notranslate"><span class="pre">python</span> <span class="pre">setup.py</span> <span class="pre">install</span></code> to
succeed even if pyrex is not available.
(John Arbash Meinel)</li>
<li><code class="docutils literal notranslate"><span class="pre">DirState._read_dirblocks</span></code> now has an optional Pyrex
implementation. This improves the speed of any command that has to
read the entire DirState. (<code class="docutils literal notranslate"><span class="pre">diff</span></code>, <code class="docutils literal notranslate"><span class="pre">status</span></code>, etc, improve by
about 10%).
<code class="docutils literal notranslate"><span class="pre">bisect_dirblocks</span></code> has also been improved, which helps all
<code class="docutils literal notranslate"><span class="pre">_get_entry</span></code> type calls (whenever we are searching for a
particular entry in the in-memory DirState).
(John Arbash Meinel)</li>
<li><code class="docutils literal notranslate"><span class="pre">bzr</span> <span class="pre">pull</span></code> and <code class="docutils literal notranslate"><span class="pre">bzr</span> <span class="pre">push</span></code> no longer do a complete walk of the
branch revision history for ui display unless -v is supplied.
(Robert Collins)</li>
<li><code class="docutils literal notranslate"><span class="pre">bzr</span> <span class="pre">log</span> <span class="pre">-rA..B</span></code> output shifted to the left margin if the log only
contains merge revisions. (Kent Gibson)</li>
<li>The <code class="docutils literal notranslate"><span class="pre">plugins</span></code> command is now public with improved help.
(Ian Clatworthy)</li>
<li>New bundle and merge directive formats are faster to generate, and</li>
<li>Annotate merge now works when there are local changes. (Aaron Bentley)</li>
<li>Commit now only shows the progress in terms of directories instead of
entries. (Ian Clatworthy)</li>
<li>Fix <code class="docutils literal notranslate"><span class="pre">KnitRepository.get_revision_graph</span></code> to not request the graph 2
times. This makes <code class="docutils literal notranslate"><span class="pre">get_revision_graph</span></code> 2x faster. (John Arbash
Meinel)</li>
<li>Fix <code class="docutils literal notranslate"><span class="pre">VersionedFile.get_graph()</span></code> to avoid using
<code class="docutils literal notranslate"><span class="pre">set.difference_update(other)</span></code>, which has bad scaling when
<code class="docutils literal notranslate"><span class="pre">other</span></code> is large. This improves <code class="docutils literal notranslate"><span class="pre">VF.get_graph([version_id])</span></code> for
a 12.5k graph from 2.9s down to 200ms. (John Arbash Meinel)</li>
<li>The <code class="docutils literal notranslate"><span class="pre">--lsprof-file</span></code> option now generates output for KCacheGrind if
the file starts with <code class="docutils literal notranslate"><span class="pre">callgrind.out</span></code>. This matches the default file
filtering done by KCacheGrind’s Open Dialog. (Ian Clatworthy)</li>
<li>Fix <code class="docutils literal notranslate"><span class="pre">bzr</span> <span class="pre">update</span></code> to avoid an unnecessary
<code class="docutils literal notranslate"><span class="pre">branch.get_master_branch</span></code> call, which avoids 1 extra connection
to the remote server. (Partial fix for #128076, John Arbash Meinel)</li>
<li>Log errors from the smart server in the trace file, to make debugging
test failures (and live failures!) easier. (Andrew Bennetts)</li>
<li>The HTML version of the man page has been superceded by a more
comprehensive manual called the Bazaar User Reference. This manual
is completed generated from the online help topics. As part of this
change, limited reStructuredText is now explicitly supported in help
topics and command help with ‘unnatural’ markup being removed prior
to display by the online help or inclusion in the man page.
(Ian Clatworthy)</li>
<li>HTML documentation now use files extension <code class="docutils literal notranslate"><span class="pre">*.html</span></code>
(Alexander Belchenko)</li>
<li>The cache of ignore definitions is now cleared in WorkingTree.unlock()
so that changes to .bzrignore aren’t missed. (#129694, Daniel Watkins)</li>
<li><code class="docutils literal notranslate"><span class="pre">bzr</span> <span class="pre">selftest</span> <span class="pre">--strict</span></code> fails if there are any missing features or
expected test failures. (Daniel Watkins, #111914)</li>
<li>Link to registration survey added to README. (Ian Clatworthy)</li>
<li>Windows standalone installer show link to registration survey
when installation finished. (Alexander Belchenko)</li>

<div class="section" id="library-api-breaks">
<h3>Library API Breaks<a class="headerlink" href="#library-api-breaks" title="Permalink to this headline">¶</a></h3>
<ul class="simple">
<li>Deprecated dictionary <code class="docutils literal notranslate"><span class="pre">bzrlib.option.SHORT_OPTIONS</span></code> removed.
Options are now required to provide a help string and it must
comply with the style guide by being one or more sentences with an
initial capital and final period. (Martin Pool)</li>
<li>KnitIndex.get_parents now returns tuples. (Robert Collins)</li>
<li>Ancient unused <code class="docutils literal notranslate"><span class="pre">Repository.text_store</span></code> attribute has been removed.
(Robert Collins)</li>
<li>The <code class="docutils literal notranslate"><span class="pre">bzrlib.pack</span></code> interface has changed to use tuples of bytestrings
rather than just bytestrings, making it easier to represent multiple
element names. As this interface was not used by any internal facilities
since it was introduced in 0.18 no API compatibility is being preserved.
The serialised form of these packs is identical with 0.18 when a single
element tuple is in use. (Robert Collins)</li>
</ul>
</div>
<div class="section" id="internals">
<h3>Internals<a class="headerlink" href="#internals" title="Permalink to this headline">¶</a></h3>
<ul class="simple">
<li>merge now uses <code class="docutils literal notranslate"><span class="pre">iter_changes</span></code> to calculate changes, which makes room for
future performance increases. It is also more consistent with other
operations that perform comparisons, and reduces reliance on
Tree.inventory. (Aaron Bentley)</li>
<li>Refactoring of transport classes connected to a remote server.
ConnectedTransport is a new class that serves as a basis for all
transports needing to connect to a remote server. transport.split_url
have been deprecated, use the static method on the object instead. URL
tests have been refactored too.
(Vincent Ladeuil)</li>
<li>Better connection sharing for ConnectedTransport objects.
transport.get_transport() now accepts a ‘possible_transports’ parameter.
If a newly requested transport can share a connection with one of the
list, it will.
(Vincent Ladeuil)</li>
<li>Most functions now accept <code class="docutils literal notranslate"><span class="pre">bzrlib.revision.NULL_REVISION</span></code> to indicate
the null revision, and consider using <code class="docutils literal notranslate"><span class="pre">None</span></code> for this purpose
deprecated. (Aaron Bentley)</li>
<li>New <code class="docutils literal notranslate"><span class="pre">index</span></code> module with abstract index functionality. This will be
used during the planned changes in the repository layer. Currently the
index layer provides a graph aware immutable index, a builder for the
same index type to allow creating them, and finally a composer for
such indices to allow the use of many indices in a single query. The
index performance is not optimised, however the API is stable to allow
development on top of the index. (Robert Collins)</li>
<li><code class="docutils literal notranslate"><span class="pre">bzrlib.dirstate.cmp_by_dirs</span></code> can be used to compare two paths by
their directory sections. This is equivalent to comparing
<code class="docutils literal notranslate"><span class="pre">path.split('/')</span></code>, only without having to split the paths.
This has a Pyrex implementation available.
(John Arbash Meinel)</li>
<li>New transport decorator ‘unlistable+’ which disables the list_dir
functionality for testing.</li>
<li>Deprecated <code class="docutils literal notranslate"><span class="pre">change_entry</span></code> in transform.py. (Ian Clatworthy)</li>
<li>RevisionTree.get_weave is now deprecated. Tree.plan_merge is now used
for performing annotate-merge. (Aaron Bentley)</li>
<li>New EmailMessage class to create email messages. (Adeodato Simó)</li>
<li>Unused functions on the private interface KnitIndex have been removed.
(Robert Collins)</li>
<li>New <code class="docutils literal notranslate"><span class="pre">knit.KnitGraphIndex</span></code> which provides a <code class="docutils literal notranslate"><span class="pre">KnitIndex</span></code> layered on top
of a <code class="docutils literal notranslate"><span class="pre">index.GraphIndex</span></code>. (Robert Collins)</li>
<li>New <code class="docutils literal notranslate"><span class="pre">knit.KnitVersionedFile.iter_parents</span></code> method that allows querying
the parents of many knit nodes at once, reducing round trips to the
underlying index. (Robert Collins)</li>
<li>Graph now has an is_ancestor method, various bits use it.
(Aaron Bentley)</li>
<li>The <code class="docutils literal notranslate"><span class="pre">-Dhpss</span></code> flag now includes timing information. As well as
logging when a new connection is opened. (John Arbash Meinel)</li>
<li><code class="docutils literal notranslate"><span class="pre">bzrlib.pack.ContainerWriter</span></code> now returns an offset, length tuple to
callers when inserting data, allowing generation of readv style access
during pack creation, without needing a separate pass across the output
pack to gather such details. (Robert Collins)</li>
<li><code class="docutils literal notranslate"><span class="pre">bzrlib.pack.make_readv_reader</span></code> allows readv based access to pack
files that are stored on a transport. (Robert Collins)</li>
<li>New <code class="docutils literal notranslate"><span class="pre">Repository.has_same_location</span></code> method that reports if two
repository objects refer to the same repository (although with some risk
of false negatives). (Andrew Bennetts)</li>
<li>InterTree.compare now passes require_versioned on correctly.
(Marius Kruger)</li>
<li>New methods on Repository - <code class="docutils literal notranslate"><span class="pre">start_write_group</span></code>,
<code class="docutils literal notranslate"><span class="pre">commit_write_group</span></code>, <code class="docutils literal notranslate"><span class="pre">abort_write_group</span></code> and <code class="docutils literal notranslate"><span class="pre">is_in_write_group</span></code> -
which provide a clean hook point for transactional Repositories - ones
where all the data for a fetch or commit needs to be made atomically
available in one step. This allows the write lock to remain while making
a series of data insertions. (e.g. data conversion). (Robert Collins)</li>
<li>In <code class="docutils literal notranslate"><span class="pre">bzrlib.knit</span></code> the internal interface has been altered to use
3-tuples (index, pos, length) rather than two-tuples (pos, length) to
describe where data in a knit is, allowing knits to be split into
many files. (Robert Collins)</li>
<li><code class="docutils literal notranslate"><span class="pre">bzrlib.knit._KnitData</span></code> split into cache management and physical access
with two access classes - <code class="docutils literal notranslate"><span class="pre">_PackAccess</span></code> and <code class="docutils literal notranslate"><span class="pre">_KnitAccess</span></code> defined.
The former provides access into a .pack file, and the latter provides the
current production repository form of .knit files. (Robert Collins)</li>
</ul>
</div>
<div class="section" id="testing">
<h3>Testing<a class="headerlink" href="#testing" title="Permalink to this headline">¶</a></h3>
<ul class="simple">
<li>Remove selftest <code class="docutils literal notranslate"><span class="pre">--clean-output</span></code>, <code class="docutils literal notranslate"><span class="pre">--numbered-dirs</span></code> and
<code class="docutils literal notranslate"><span class="pre">--keep-output</span></code> options, which are obsolete now that tests
are done within directories in $TMPDIR. (Martin Pool)</li>
<li>The SSH_AUTH_SOCK environment variable is now reset to avoid
interaction with any running SSH agents. (Jelmer Vernooij, #125955)</li>
<li>run_bzr_subprocess handles parameters the same way as run_bzr:
either a string or a list of strings should be passed as the first
parameter. Varargs-style parameters are deprecated. (Aaron Bentley)</li>
