Thanks to everyone's support, 1.7 final has now arrived.
This isn't quite as spectacular a release as the 1.6, but it is *almost* on
time. :) We slipped a week, but at least we didn't slip a month (or more).
This release includes many bug fixes and a few performance and feature
improvements. "bzr rm" will now scan for missing files and remove them,
similar to ``bzr add`` with unknown files. A bit more polish has been applied
to the stacking code. The b-tree indexing code has been brought in, with an
eye on using it in a future repository format.
The source code and installers are available (or will be available soon) from:
https://launchpad.net/bzr/1.7/1.7/
Ubuntu packages will be available from the bzr ppa:
https://launchpad.net/~bzr/+archive

Release Notes for all changes in bzr 1.7:
bzr 1.7 2008-09-23
- ------------------
This release includes many bug fixes and a few performance and feature
improvements. ``bzr rm`` will now scan for missing files and remove them,
like how ``bzr add`` scans for unknown files and adds them. A bit more
polish has been applied to the stacking code. The b-tree indexing code has
been brought in, with an eye on using it in a future repository format.
There are only minor installer changes since bzr-1.7rc2.
FEATURES
* Some small updates to the win32 installer. Include localization
files found in plugins, and include the builtin distutils as part of
packaging qbzr. (Mark Hammond)
bzr 1.7rc2 2008-09-17
- ---------------------
A few bug fixes from 1.7rc1. The biggest change is a new
``RemoteBranch.get_stacked_on_url`` rpc. This allows clients that are
trying to access a Stacked branch over the smart protocol, to properly
connect to the stacked-on location.
BUG FIXES:
* Branching from a shared repository on a smart server into a new
repository now preserves the repository format.
(Andrew Bennetts, #269214)
* Branching from a stacked branch via ``bzr+ssh`` can properly connect
to the stacked-on branch. (Martin Pool, #261315)
* ``bzr init`` no longer re-opens the BzrDir multiple times.
(Vincent Ladeuil)
* Fix '_in_buffer' AttributeError when using the -Dhpss debug flag.
(Andrew Bennetts)
bzr 1.7rc1 2008-09-09
- ---------------------
This release candidate for bzr 1.7 has several bug fixes and a few
performance and feature improvements. ``bzr rm`` will now scan for
missing files and remove them, like how ``bzr add`` scans for unknown
files and adds them. A bit more polish has been applied to the stacking
code. The b-tree indexing code has been brought in, with an eye on using
it in a future repository format.
CHANGES:
* ``bzr export`` can now export a subdirectory of a project.
(Robert Collins)
* ``bzr rm`` will now scan for files that are missing and remove just
them automatically, much as ``bzr add`` scans for new files that
are not ignored and adds them automatically. (Robert Collins)
FEATURES
* Support for GSSAPI authentication when using FTP as documented in
RFC2228. (Jelmer Vernooij, #49623)
IMPROVEMENTS:
* A url like ``log+file:///tmp`` will log all access to that Transport
to ``.bzr.log``, which may help in debugging or profiling.
(Martin Pool)
* ``bzr branch`` and ``bzr push`` use the default stacking policy if the
branch format supports it. (Aaron Bentley)
* ``bzr init`` and ``bzr init-repo`` will now print out the same as
``bzr info`` if it completed successfully.
(Marius Kruger)
* ``bzr uncommit`` logs the old tip revision id, and displays how to
restore the branch to that tip using ``bzr pull``. This allows you
to recover if you realize you uncommitted the wrong thing.
(John Arbash Meinel)
* Fix problems in accessing stacked repositories over ``bzr://``.
(Martin Pool, #261315)
* ``SFTPTransport.readv()`` was accidentally using ``list += string``,
which 'works', but adds each character separately to the list,
rather than using ``list.append(string)``. Fixing this makes the
SFTP transport a little bit faster (~20%) and use a bit less memory.
(John Arbash Meinel)
* When reading index files, if we happen to read the whole file in a
single request treat it as a ``_buffer_all`` request. This happens
most often on small indexes over remote transports, where we default
to reading 64kB. It saves a round trip for each small index during
fetch operations. Also, if we have read more than 50% of an index
file, trigger a ``_buffer_all`` on the next request. This works
around some inefficiencies because reads don't fall neatly on page
boundaries, so we would ignore those bytes, but request them again
later. This could trigger a total read size of more than the whole
file. (John Arbash Meinel)
BUG FIXES:
* ``bzr rm`` is now aliased to ``bzr del`` for the convenience of svn
users. (Robert Collins, #205416)
* Catch the infamous "select/poll returned error" which occurs when
pycurl try to send a body request to an HTTP/1.0 server which has
already refused to handle the request. (Vincent Ladeuil, #225020)
* Fix ``ObjectNotLocked`` errors when using various commands
(including ``bzr cat`` and ``bzr annotate``) in combination with a
smart server URL. (Andrew Bennetts, #237067)
* ``FTPTransport.stat()`` would return ``0000`` as the permission bits
for the containing ``.bzr/`` directory (it does not implement
permissions). This would cause us to set all subdirectories to
``0700`` and files to ``0600`` rather than leaving them unmodified.
Now we ignore ``0000`` as the permissions and assume they are
invalid. (John Arbash Meinel, #259855)
* Merging from a previously joined branch will no longer cause
a traceback. (Jelmer Vernooij, #203376)
* Pack operations on windows network shares will work even with large
files. (Robert Collins, #255656)
* Running ``bzr st PATH_TO_TREE`` will no longer suppress merge
status. Status is also about 7% faster on mozilla sized trees
when the path to the root of the tree has been given. Users of
the internal ``show_tree_status`` function should be aware that
the show_pending flag is now authoritative for showing pending
merges, as it was originally. (Robert Collins, #225204)
* Set valid default _param_name for Option so that ListOption can embed
'-' in names. (Vincent Ladeuil, #263249)
* Show proper error rather than traceback when an unknown revision
id is specified to ``bzr cat-revision``. (Jelmer Vernooij, #175569)
* Trailing text in the dirstate file could cause the C dirstate parser
to try to allocate an invalid amount of memory. We now properly
check and test for parsing a dirstate with invalid trailing data.
(John Arbash Meinel, #186014)
* Unexpected error responses from a smart server no longer cause the
client to traceback. (Andrew Bennetts, #263527)
* Use a Windows api function to get a Unicode host name, rather than
assuming the host name is ascii.
(Mark Hammond, John Arbash Meinel, #256550)
* ``WorkingTree4`` trees will now correctly report missing-and-new
paths in the output of ``iter_changes``. (Robert Collins)
DOCUMENTATION:
* Updated developer documentation. (Martin Pool)
API CHANGES:
* Exporters now take 4 parameters. (Robert Collins)
* ``Tree.iter_changes`` will now return False for the content change
field when a file is missing in the basis tree and not present in
the target tree. Previously it returned True unconditionally.
(Robert Collins)
* The deprecated ``Branch.abspath`` and unimplemented
``Branch.rename_one`` and ``Branch.move`` were removed. (Jelmer Vernooij)
* BzrDir.clone_on_transport implementations must now accept a stacked_on
parameter. (Aaron Bentley)
* BzrDir.cloning_metadir implementations must now take a require_stacking
parameter. (Aaron Bentley)
TESTING:
* ``addCleanup`` now takes ``*arguments`` and ``**keyword_arguments``
which are then passed to the cleanup callable as it is run. In
addition, addCleanup no longer requires that the callables passed to
it be unique. (Jonathan Lange)
* Fix some tests that fail on Windows because files are deleted while
still in use.
(Mark Hammond)
* ``selftest``'s ``--starting-with`` option can now use predefined
prefixes so that one can say ``bzr selftest -s bp.loom`` instead of
``bzr selftest -s bzrlib.plugins.loom``. (Vincent Ladeuil)
* ``selftest``'s ``--starting-with`` option now accepts multiple values.
(Vincent Ladeuil)
INTERNALS:
* A new plugin interface, ``bzrlib.log.log_adapters``, has been added.
This allows dynamic log output filtering by plugins.
(Robert Collins)
* ``bzrlib.btree_index`` is now available, providing a b-tree index
layer. The design is memory conservative (limited memory cache),
faster to seek (approx 100 nodes per page, gives 100-way fan out),
and stores compressed pages allowing more keys per page.
(Robert Collins, John Arbash Meinel)
* ``bzrlib.diff.DiffTree.show_diff`` now skips changes where the kind
is unknown in both source and target.
(Robert Collins, Aaron Bentley)
* ``GraphIndexBuilder.add_node`` and ``BTreeBuilder`` have been
streamlined a bit. This should make creating large indexes faster.
(In benchmarking, it now takes less time to create a BTree index than
it takes to read the GraphIndex one.) (John Arbash Meinel)
* Mail clients for `bzr send` are now listed in a registry. This
allows plugins to add new clients by registering them with
``bzrlib.mail_client.mail_client_registry``. All of the built-in
clients now use this mechanism. (Neil Martinsen-Burrell)
