From here, we +will only make bugfix releases on the 2.5 series (2.5.1, etc, and support it +until April 2017), while 2.6 will become our new development series. + +This is a bugfix and polish release over the 2.4 series, with a large number +of bugs fixed (~170 for the 2.5 series alone). The 2.5 series provides a +faster smart protocol implementation for many operations, basic support for +colocated branches. We have started translating bzr with the 2.5 series: +https://translations.launchpad.net/bzr, more than 20 languages have already +been registered but these are the early days, contributions welcome. + +Only a few bugfixes have been included since 2.5b6 so all known fixed bugs +are included here. + +Users are encouraged to upgrade from the other stable series. + + +External Compatibility Breaks +***************************** + +None. + +New Features +************ + +None. + +Improvements +************ + +* The names of colocated branches are used as branch nicks if no nick is + specified.

(Jelmer Vernooij, #905594) + +* A sane default is provided for ``ssl.ca_certs`` which should points to the + Certificate Authority bundle for supported platforms. + (Vincent Ladeuil, #920455) + +* ``bzr branch`` generates correct target branch locations again if not + specified. (Jelmer Vernooij, #919218) + +* ``bzr send`` works on treeless branches again. + (Jelmer Vernooij, #921591) + +* ``bzr version`` no longer throws a UnicodeDecodeError if the .bzr.log path + contains non-ascii characters. (Martin Packman, #312841) + +* Support scripts that don't call bzrlib.initialize() but still call run_bzr(). + (Vincent Ladeuil, #917733) + +* Test for equality instead of object identity where ROOT_PARENT is concerned. + (Wouter van Heyst, #881142) + +* urllib-based HTTPS client connections now verify the server certificate + validity as well as the hostname. + (Jelmer Vernooij, Vincent Ladeuil, #651161) + + +API Changes +*********** + +* ``config.config_dir`` and related functions now always return paths as + unicode.

Beta releases are suitable for everyday use but +may cause some incompatibilities with plugins. + +This release includes many improvements in the smart server, UI polish for +the colocated branches, enhancements to the config framework and more +internal uses, bug fixes related to unicode and locale support and more. + +All bug fixed in previous series known at the time of this release are +included. + +External Compatibility Breaks +***************************** + +* The '.bzr/branch/email' file is no longer read to determine the users' + identity. Instead, the 'email' setting in '.bzr/branch/branch.conf' + should be used. (Jelmer Vernooij, #903894) + +New Features +************ + +* "bzr mkdir" now includes -p (--parents) option for recursively adding + parent directories. + (Jared Hance, Jelmer Vernooij, #253529) + +* ``config.Option`` can now declare ``override_from_env``, a list of + environment variables which, when set, that takes precedence over values + defined in configuration files. (Vincent Ladeuil, #907279) + +Improvements +************ + +* New HPSS call for ``Repository.reconcile``. (Jelmer Vernooij, #894455) + +* Merge now has two new hooks ``pre_merge`` and ``post_merge`` + that are called before and after a merge and can make + additional modifications to the trees involved. + (Jelmer Vernooij, #906877) + +* Override the value returned by ``sys.getfilesystemencoding()`` for the bzr + script to utf-8 when it would otherwise be ascii on a posix system. This + will mean bzr works with non-ascii files when no locale or an incorrect + locale is set. (Martin Packman, #794353) + +* ``bzr branches`` now indicates the active colocated branch. + (Jelmer Vernooij, #891667) + +* ``bzr push`` now suggests using :parent if there is a parent location + set. (Jelmer Vernooij) + +* ``bzr send`` now only opens a single connection, rather than two, + to the target branch. (Jelmer Vernooij) + +Bug Fixes +********* + +* Allow configuration option default value to be a python callable at + registration. (Vincent Ladeuil, #832064) + +* ``bzr config`` will now display the section ``[DEFAULT]`` used in + ``bazaar.conf``. (Vincent Ladeuil, #907268) + +* Configuration stores can now provides a specific quoting mechanism. This + is required to workaround ``configobj`` conflating quoting and list values + automatic conversion. (Vincent Ladeuil, #906897) + +* Create obsolete_packs directory when repacking if it does not + exist. (Jonathan Riddell, Jelmer Vernooij, #314314) + +* Fallback to the slower ``bzr log`` implementation when displaying a range + of revisions whose ancestry is not obviously on the same developement + line. (Vincent Ladeuil, #904744) + +* Make lazy imports resilient when resolved concurrently from multiple + threads. Now the stand-in object will behave as a proxy for the real object + after the initial access, rather than throwing. Assigning the object to + multiple names should still be avoided. (Martin von Gagern, #396819) + +* Not setting ``gpg_signing_key`` or setting it to ``default`` will use the + user email (obtained from the ``email`` configuration option or its + default value). (Vincent Ladeuil, Jelmer Vernooij, #904550) + +* Prevent spurious InconsistentDelta error when committing a move of a + non-ascii directory with contents. (Rory Yorke, #185211) + +* Properly ignore '\n' in an option reference since this cannot be part of a + config option identifier. (Vincent Ladeuil, #902125) + +* Make sure that the bzr probers are always registered when + bzrlib.workingtree is imported. (Jelmer Vernooij, #905218) + +* Report mistake trying to move a removed file with a non-ascii name without + UnicodeEncodeError being raised. (Martin Packman, #898541) + +* Safely unquote configuration values in weird edge cases (a section seen as + a dictionary which is not a supported use case for the configuration + stacks). (Vincent Ladeuil, #908050) + +* Stop altering ``sys.platform`` on OSX when initialising the locale. + (Martin Packman, #570495) + +* Uncommit no longer removes tags if they are part of the working + trees pending merges. (Jelmer Vernooij, #905462) + +API Changes +*********** + +* ``Config.signature_needed``, ``Config.signing_policy``, + ``Config.gpg_signing_key``, ``Config.gpg_signing_command``, + ``Config.checking_policy`` and ``Config.post_commit`` are now deprecated. + (Jelmer Vernooij) + +* ``Repository.get_commit_builder`` now takes a ``config_stack`` + rather than a ``config`` argument. (Jelmer Vernooij) + +* Scripts using bzrlib should now ensure setlocale is called on posix + platforms if they need a non-ascii user encoding. (Martin Packman) + +* Send formats now accept a new optional argument ``submit_branch``, + which can be None or a Branch object for the submit branch location. + (Jelmer Vernooij) + +* ``VersionedFileRepository.add_revision`` no longer takes a ``config`` + argument. (Jelmer Vernooij) + +Internals +********* + +* Add HPSS call for ``Branch.get_checkout_format``. (Jelmer Vernooij, #894459) + +* Add HPSS call for ``Repository.pack``. (Jelmer Vernooij, #894461) + +* Add HPSS calls for ``Repository.iter_files_bytes``, speeding up + several commands including ``bzr export`` and ``bzr co --lightweight``. + (Jelmer Vernooij, #608640) + +* All bzr control directories, branch formats, repository formats and + working tree formats now support feature flags, which are + serialized in their respective format files. See + ``doc/developers/feature-flags.txt`` for details. + (Jelmer Vernooij) + +* ``bzrlib.urlutils`` now includes ``quote`` and ``unquote`` functions, + rather than importing them from ``urllib``. This prevents loading + of the ``socket``, ``ssl`` and ``urllib`` modules for + local bzr operations. (Jelmer Vernooij) + +* Configuration options can be SI units by using ``int_SI_from_unicode`` as + their ``convert_from_unicode`` helper. (Vincent Ladeuil) + +* Configuration stacks can now use ``StartingPathMatcher`` to select the + sections matching a location while respecting the order chosen by the user + in the configuration file: from generic sections to specific + sections. (Vincent Ladeuil, #832046). + +* Configuration stores can now save incremental changes by using + ``save_changes()`` instead of ``save()``. This reduces the number or + required input/outputs and allows stores to be shared between + stacks. (Vincent Ladeuil) + +* ControlDir now has a get_branches method that returns a dictionary + whose keys are the names of the branches and whose values are the + branches themselves. The active branch uses the key None. + (Neil Martinsen-Burrell) + +* Helper ``osutils.path_from_environ`` added for extracting a unicode path + from an environment variable. (Martin Packman, #832028) + +* Helper ``win32utils.get_environ_unicode`` added for avoiding encoding + problems with ``os.environ.get`` use. (Martin Packman, #262874) + +* Lazy imports can now only be absolute. (Jelmer Vernooij) + +* Merge3Mergers now have an optional ``other_branch`` argument + which contains the branch from which the ``other_tree`` + was obtained, if any. (Jelmer Vernooij) + +* MutableTree now has a hook ``post_build_tree`` which is called after + a new mutable tree has been created. (Jelmer Vernooij, #912765) + +* New HPSS call ``BzrDir.checkout_metadir``. (Jelmer Vernooij, #894459) + +* New HPSS call ``VersionedFileRepository.get_inventories``, + speeding up various commands including ``bzr export``, + ``bzr checkout`` and ``bzr cat``. (Jelmer Vernooij, #608640) + +* The ``ConfigCommandLineStore`` is now supported by ``bzr config`` and is + seen as single no-name section of configuration options. (Vincent Ladeuil) + +Testing +******* + +* New matcher ``ContainsNoVfsCalls`` which filters a list of HPSS + calls for VFS requests. (Jelmer Vernooij) + +* New ``MemoryStack`` class allows for diskless tests and locally injected + configuration stacks. Lower level tests for predefined set of options can + be written without setting up configuration files. (Vincent Ladeuil) + + +bzr 2.5b4 +######### + +:2.5b4: 2011-12-08 + +This is the fourth beta of the 2.5 series, leading to a 2.5.0 release in +February 2012.

See ``bzr help po_merge`` for details. + (Vincent Ladeuil, #884270) + +Improvements +************ + +* ``bzr branch --stacked`` now only makes a single connection to the remote + server rather than three. (Jelmer Vernooij, #444293) + +* ``bzr export --uncommitted`` will export the uncommitted tree. + (Jelmer Vernooij, #555613) + +* ``bzr rmbranch`` can now remove colocated branches. + (Jelmer Vernooij, #831464) + +* ``bzr status`` no longer shows shelves if files are specified. + (Francis Devereux) + +* ``bzr switch`` now accepts colocated branch names to switch to. + (Jelmer Vernooij, #826814) + +* Plugins can now register additional "location aliases". + (Jelmer Vernooij) + +* Revision specifiers will now only browse as much history as they + need to, rather than grabbing the whole history unnecessarily in some + cases. (Jelmer Vernooij) + +* When using ``bzr switch`` to switch to a sibling of the current + branch, the relative branch name should no longer be url-encoded. + (Jelmer Vernooij) + +Bug Fixes +********* + +* A new section local option ``basename`` is available to help support some + ``bzr-pipeline`` workflows and more generally help mapping local paths to + remote ones. See ``bzr help configuration`` for more details. + (Vincent Ladeuil, #843211) + +* Add HPSS call for looking up revision numbers from revision ids on + remote repositories. (Jelmer Vernooij, #640253) + +* Add HPSS call for retrieving file contents from remote repositories. + Should improve performance for lightweight checkouts and exports of + from remote repositories.

(Jelmer Vernooij, #159098) + +* Cope with missing revision ids being specified to + ``Repository.gather_stats`` HPSS call. (Jelmer Vernooij, #411290) + +* Fix test failures on windows related to locations.conf handling. + (Vincent Ladeuil, #892992) + +* Fixed parsing of the timestamp given to ``commit --commit-time``. Now + prohibits several invalid strings, reads the correct number of seconds, + and gives a better error message if the time zone offset is not given. + (Matt Giuca, #892657) + +* Give meaningful file/line references when reporting deprecation warnings + for _CompatabilityThunkFeature based test features. + (Vincent Ladeuil, #897718) + +* Make reporting of mistakes involving unversioned files with non-ascii + filenames work again without 'Unprintable exception' being shown. + (Martin Packman, #898408) + +* Provide names for lazily registered hooks. + (Neil Martinsen-Burrell, #894609) + +* Raise BadIndexKey exception in btree_index when a key is too large, fixing + an infinite recursion issue. (Shannon Weyrick, #720853) + +* Resolve regression from colocated branch path handling, by ensuring that + unreserved characters are unquoted in URLs.

This doesn't handle all possible network + disconnects, but it should at least handle when the server is asked to + shutdown gracefully. (John Arbash Meinel, #819604) + +* When a remote format is unknown, bzr will now print a single-line error + message rather than a backtrace. (Jelmer Vernooij, #687226) + +API Changes +*********** + +* ``BzrDir.open_branch`` and ``BranchFormat.open`` now take an optional + ``possible_transports`` argument.

This greatly reduces the peak resource needs of a full test suite + run. The new ``-Euncollected_cases`` selftest flag will add failures if any + case which persists pasts its expected lifetime. (Martin Packman, #613247) + +* Report exceptions from child processes during fork instead of swallowing the + error and reporting that everything went okay. (Martin Packman, #804130) + + +bzr 2.5b2 +######### + +This is the second beta of the 2.5 series, leading to a 2.5.0 release in +February 2012. Beta releases are suitable for everyday use but may cause some +incompatibilities with plugins. + +This release includes more filtering options for ``bzr log``, idle +connections handling for ``bzr serve``, a ``development-colo`` experimental +format to flesh out the colocated branches UI, better support for foreign +formats, enhancements to the config framework and more. + +This release includes all bug fixed in previous series known at the time of +this release. + +:2.5b2: 2011-10-06 + +External Compatibility Breaks +***************************** + +None + +New Features +************ + +* A new ``-O`` standard option (common to all commands) have been added. It + provides a value for a config option in the ``-Oname=value`` form that + takes precedence over all definitions found in config files. It can be + used multiple times to override different options. + (Vincent Ladeuil, #491196) + +* ``bzr log`` now has an option called ``--omit-merges`` to omit + those commits that merged branches, i.e. those having more than one + parent. + In order to avoid confusion, the previous command line option + ``--include-merges`` has been renamed to ``--include-merged``. + The old name of the command line option will still be accepted. + The name change also affects ``bzr missing``. + (Martin von Gagern) + +* ``bzr serve`` will now disconnect clients if they have not issued an RPC + request after 5minutes. On POSIX platforms, this will also happen for + ``bzr serve --inet``. This can be overridden with the configuration + variable ``serve.client_timeout`` or in the command line parameter + ``bzr serve --client-timeout=X``. Further, it is possible to request + ``bzr serve [--inet]`` to shutdown gracefully by sending SIGHUP. It will + finish the current request, and then close the connection. + (John Arbash Meinel, #824797, #795025) + +* The new experimental format ``development-colo`` supports colocated + branches. This format will eventually be merged back into the ``2a`` + format when it has stabilized and there is adequate UI support for + colocated branches. + (Jelmer Vernooij, #831481) + +Improvements +************ + +* Fixed a bug where ``bzr tags -r x..y`` loaded the branch history once for + every revision in the range; it's now much faster. (Vincent Ladeuil, #857335) + +* ``bzr info -v`` can now be run against branches that don't support + ``last_revision_info``, in which case the branch information will simply + not be displayed. (Jelmer Vernooij) + +Bug Fixes +********* + +* ``bzr shelve`` can now be used in emacs shells as the input handling is + turned into a line-based one when ``INSIDE_EMACS`` is set (which is the + case for all recent emacs versions). (Vincent Ladeuil, #856261) + +* ``bzr tags`` can now be used against remote repositories that do + not provide access to the revision graph. (Jelmer Vernooij, #858942) + +* ``bzr update PATH`` will stop if you seem to be asking it to update + anything less than a whole tree, because that's not supported by ``bzr``'s + concept that the whole tree has a single basis revision. Previously, it + would go ahead and update the whole tree, which was surprising. + (Martin Pool, #557886) + +* Don't crash if ``bzrlib.initialize()`` has not been called while accessing + configs. (Vincent Ladeuil, #863401) + +* Redirects between http and https no longer discard path information + in some cases. (Jelmer Vernooij, #853765) + +* The ``--overwrite`` argument to ``bzr push`` and ``bzr pull`` no longer + reports all tags as changed. (Jelmer Vernooij, #845396) + +* ``WorkingTree.get_file_mtime`` now raises NoSuchId if a file id is + specified that is unknown. (Jelmer Vernooij, #847435) + + +API Changes +*********** + +* ``Branch.get_revision_delta`` has been deprecated. Use + ``Repository.get_revision_delta`` instead. (Jelmer Vernooij, #859712) + +* Plugins that implement custom protocols for ``bzr serve`` should now + also take an argument ``timeout``. This is used by the the bzr protocol + to close a connection if a client has been idle for more than X seconds. + (Default 5minutes). (John Arbash Meinel) + +* ``Repository.fileids_altered_by_revision_ids`` has been moved to + ``VersionedFileRepository`` and is no longer part of the standard + ``Repository`` interface. (Jelmer Vernooij) + +* The argument ``include_merges`` to ``missing.find_unmerged`` has + been renamed to ``include_merged``. The old name is still supported + for now but will cause a deprecation warning. (Martin von Gagern) + +* The new method ``ControlDirFormat.is_initializable()`` returns a boolean + indicating whether or not it is possible to use any of the + initialization methods of that format to create a new control dir. + (Jelmer Vernooij) + +Internals +********* + +* ``Branch`` objects can now use a config stack with the newly introduced + ``get_config_stack()``. Both ``get_config`` and ``get_config_stack`` can + be used for the same branch but it's recommended to stick to one for a + given option. + +Testing +******* + +* Test scripts can now use ``bzr shelve`` and provide their input as + complete lines. (Vincent Ladeuil, #856261) + +* Really corrupt the pack file without depending on a special length or value. + (Vincent Ladeuil, #807032) + + +bzr 2.5b1 +######### + +:2.5b1: 2011-09-15 + +This is the first beta of the 2.5 series, leading up to a 2.5.0 +release in February 2012. + +This release includes better support for gpg signing, better support for +i18n (mostly command help and error messages), more options to filter ``bzr +log`` output, more support for colocated branches ("location,branch=XXX" +syntax), better feedback on updated tags for various commands, faster +branching into an empty repository, enhancements to the config framework and +more. + +Beta releases are suitable for everyday use but may cause some +incompatibilities with plugins. Some plugins may need small updates to work +with 2.5b1. + +External Compatibility Breaks +***************************** + +None + +New Features +************ + +* A ``from_unicode`` parameter can be specified when registering a config + option. This implements boolean, integer and list config options when the + provided ``bool_from_store``, ``int_from_store`` and ``list_from_store`` + are used for this parameter. (Vincent Ladeuil) + +* Accessing a packaging branch on Launchpad (eg, ``lp:ubuntu/bzr``) now + checks to see if the most recent published source package version for + that project is present in the branch tags. This should help developers + trust whether the packaging branch is up-to-date and can be used for new + changes. The level of verbosity is controlled by the config item + ``launchpad.packaging_verbosity``. It can be set to one of + + off + disable all checks + + + minimal + only display if the branch is out-of-date + + short + also display single-line up-to-date and missing, + + + all + (default) display multi-line content for all states + + + (John Arbash Meinel, #609187, #812928) + +* Add a config option gpg_signing_key for setting which GPG key should + be used to sign commits. Also default to using the gpg user identity + which matches user_email() as set by whoami. + (Jonathan Riddell, #68501) + +* An ``invalid`` parameter can be specified when registering a config option + to decide what should be done when invalid values are + encountered. 'warning' and 'error' will respectively emit a warning and + ignore the value or errors out. (Vincent Ladeuil) + +* bzr add now skips large files in recursive mode. The default "large" + size is 20MB, and is configurable via the add.maximum_file_size + option. A value of 0 disables skipping. Named items passed to add are + never skipped. (Shannon Weyrick, #54624) + +* ``bzr help configuration/<option>`` display the help for ``option`` for + all registered configuration options. (Vincent Ladeuil, #747050) + +* ``bzr log -m`` now matches message, author, committer and bugs instead + of just matching the message. ``--message`` keeps its original meaning, + while ``--match-message, --match-author, --match-committer`` and + ``--match-bugs`` match each of those fields. (Jacek Sieka) + +* ``config.Option`` can now declare ``default_from_env``, a list of + environment variables to get a default value from. (Vincent Ladeuil) + +* ``config.NameMatcher`` can be used to implement config stores and stacks + that need to provide specific option values for arbitrary unique IDs (svn + repository UUIDs, etc). (Vincent Ladeuil, #843638) + +* New builtin ``bzr branches`` command, which lists all colocated branches + in a directory. (Jelmer Vernooij, #826820) + +* Relative local paths can now be specified in URL syntax by using the + "file:" prefix. (Jelmer Vernooij) + +* Report commits signed with expired keys in ``verify-signatures``. + (Jonathan Riddell, #804254) + +* Translations are now enabled for command help, errors and globally + for any message using ``gettext`` given on output. (Jonathan Riddell, + INADA Naoki, #83941) + +Improvements +************ + +* ``bzr add`` will now warn about nested subtrees that are skipped. + (Jelmer Vernooij, #187342) + +* ``bzr commit -m ''`` can now be used to force an empty commit message. + Entering an empty commit message in the message editor still triggers + an error. (Jelmer Vernooij) + +* ``bzr pull`` will now mention how many tags it has updated. + (Jelmer Vernooij, #164450) + +* ``bzr tag`` no longer errors if a tag already exists but refers to the + same revision, and will mention when a tag has been updated + rather than created. (Jelmer Vernooij, #381203) + +* ``bzr uncommit`` will now remove tags that refer to removed revisions. + The ``--keep-tags`` option can be used to prevent this behaviour. + (Jelmer Vernooij, #605814) + +* Do not run i18n initialisation twice. (Jonathan Riddell) + +* Install translation .mo files. (Jonathan Riddell) + +* Locations printed by ``bzr upgrade`` are now formatted before display. + (Jelmer Vernooij) + +* ``Repository.get_parent_map`` now estimates the size of the returned + content more accurately. This means that we get closer to the desired + 64kB/request. For repositories converted from svn, this can be an + improvement of approx 5:1 in round trips to discover the whole history. + (John Arbash Meinel) + +* Support a ``bugtracker`` option which is used by ``bzr commit --fixes`` + if no bug tracker was specified on the command line. + (Jelmer Vernooij, #334860) + +* Use ``gettext.NullTranslations`` in i18n to allow use of i18n even when + translations are not turned on. (Jonathan Riddell) + +Bug Fixes +********* + +* ``bzr commit`` now correctly reports missing files as "removed", not + "modified". (Jelmer Vernooij, #553955) + +* ``bzr reconfigure`` will now allow multiple non-conflicting requests + in a single invocation, e.g. ``--branch`` and ``--use-shared``. + (Martin von Gagern, #842993) + +* A call to CHKInventory's filter-method will not result in a + DuplicateFileId error, if you move a subfolder and change a file in + that subfolder. + (Bastian Bowe, #809901) + +* Branching from a stacked branch no longer does a ``get_parent_map`` + request for each revisions that is in the stacked-on repository while + determining what revisions need to be fetched. This mostly impacts + branching initialy into an empty shared repository when the source is + not the development focus. (John Arbash Meinel, #388269) + +* Decode ``BZR_HOME`` with fs encoding on posix platforms to avoid unicode + errors. (Vincent Ladeuil, #822571) + +* Fix fallout from URL handling changes in 2.5 that caused an IndexError to be + raised whenever a transport at the drive root was opened on windows. + (Martin [gz], #841322) + +* Fixed loading of external merge tools from config to properly decode + command-lines which contain embedded quotes. (Gordon Tyler, #828803) + +* Rather than an error being raised, a warning is now printed when the + current user does not have permission to read a configuration file. + (Jelmer Vernooij, #837324) + +* The pull command will now always use separate connections for the + case where the destination is a heavyweight checkout of some remote + branch on the same host as the source branch. + (Martin von Gagern, #483661) + +* TreeTransformBase.fixup_new_roots no longer forces trees to have a root, so + operations that use it, like merge, can now create trees without a root. + (Aaron Bentley) + +Documentation +************* + +* Release instructions refreshed. (Vincent Ladeuil) + +API Changes +*********** + +* ``BranchFormat.initialize`` now takes a ``append_revisions_only`` + argument. (Jelmer Vernooij) + +* ``Branch._get_checkout_format`` now takes a ``lightweight`` argument + which indicates if the format should be for a lightweight or a + heavyweight checkout. (Jelmer Vernooij) + +* ``ControlDir.create_branch`` now takes a ``append_revisions_only`` argument. + (Jelmer Vernooij) + +* New class ``URL`` in ``bzrlib.utils`` for managing parsed URLs. + (Jelmer Vernooij) + +* New method ``Config.get_user_option_as_int_from_SI`` added for expanding a + value in SI format (i.e. "20MB", "1GB") into its integer equivalent. + (Shannon Weyrick) + +* New method ``InterTree.file_content_matches`` which checks that + two files in different trees have the same contents. + (Jelmer Vernooij) + +* New method ``Tree.get_file_verifier`` which allows tree implementations + to return non-sha1 checksums to verify files. + (Jelmer Vernooij, #720831) + +* New methods ``get_transport_from_path`` and ``get_transport_from_url`` + have been added that only support opening from a path or a URL, + unlike ``get_transport``. (Jelmer Vernooij) + +* New registry ``OptionRegistry`` specialized for configuration options. + (Vincent Ladeuil) + +* Remove ``AtomicFile.closed`` which has been deprecated in bzr 0.10. + (Vincent Ladeuil) + +* Remove ``commands._builtin_commands``, ``commands.shlex_split_unicode``, + ``Command._maybe_expand_globs`` and ``Command.run_direct`` deprecated in + 2.10 and 2.2.0. (Vincent Ladeuil) + +* Remove ``diff.get_trees_and_branches_to_diff`` deprecated in 2.2.0. + +* Remove ``log.calculate_view_revisions``, ``log._filter_revision_range``, + ``log.get_view_revisions`` which have been deprecated in bzr 2.1.0. Also + remove ``log.show_one_log`` which was never properly deprecated but wasn't + used and is easy to inline if needed. (Vincent Ladeuil) + +* Remove ``trace.info``, ``trace.error`` and ``trace.show_log_error`` + deprecated in 2.1.0. (Vincent Ladeuil) + +* Remove ``TransportListRegistry.set_default_transport``, as the concept of + a default transport is currently unused. (Jelmer Vernooij) + +* Remove ``UIFactory.warn_cross_format_fetch`` and + ``UIFactory.warn_experimental_format_fetch`` in favor of + ``UIFactory.show_user_warning``. (Jelmer Vernooij) + +* ``Tags`` containers can now declare whether they support versioned + tags and whether tags can refer to ghost tags. + (Jelmer Vernooij) + +* ``Tags.merge_to`` now returns a dictionary with the updated tags + and a set of conflicts, rather than just conflicts. (Jelmer Vernooij) + +* There is a new class `ContentFilterTree` that provides a facade for + content filtering. The `filtered` parameter to `export` is deprecated + in favor of passing a filtered tree, and the specific exporter plugins + no longer support it. + (Martin Pool) + +* ``Transport`` now has a ``_parsed_url`` attribute instead of + separate ``_user``, ``_password``, ``_port``, ``_scheme``, ``_host`` + and ``_path`` attributes. Proxies are provided for the moment but + may be removed in the future. (Jelmer Vernooij) + +Internals +********* + +* A new debug flag ``hpss_client_no_vfs`` will now cause the HPSS client + to raise a ``HpssVfsRequestNotAllowed`` exception when a VFS request + is attempted. (Jelmer Vernooij) + +* New method ``ControlDir._get_selected_branch`` which returns the + colocated branch selected using path segment parameters. + (Jelmer Vernooij, #380871) + +Testing +******* + +* Blackbox tests (including test scripts) can be debugged interactively (see + bzrlib.debug.BzrPdb for details). (Vincent Ladeuil) + +* `BranchBuilder.build_snapshot` now supports a "flush" action. This + cleanly and reliably allows tests using `BranchBuilder` to construct + branches that e.g. rename files out of a directory and unversion that + directory in the same revision. Previously some changes were impossible + due to the order that `build_snapshot` performs its actions. + (Andrew Bennetts) + +* Don't require ``os.fdatasync`` to be defined on all supported OSes + (BSD-based OSes don't define it). (Vincent Ladeuil, #822649) + +* Fix compatibility with testtools 0.9.12. (Jelmer Vernooij, #815423) + +* ``LockDir`` can now be run when the local hostname is ``localhost``. + (Jelmer Vernooij, #825994) + +* ``ModuleAvailableFeature`` won't try to import already imported modules, + allowing it to be used for modules with side-effects. + (Vincent Ladeuil, #712474) + +* Output time stamps while running ``make check`` to get better timings from + pqm. (Vincent Ladeuil, #837926) + +* `TestCaseWithMemoryTransport` is faster now: `_check_safety_net` now + just compares the bytes in the dirstate file to its pristine state, + rather than opening the WorkingTree and calling ``last_revision()``. + This reduces the overall test suite time by about 10% on my laptop. + (Andrew Bennetts) + +* Update `TestCase.knownFailure` to the testtools way of handling expected + failures to resolve Python 2.7 incompatibility.
