-GIT v1.5.2 Release Notes (draft)
+GIT v1.5.2 Release Notes
========================
Updates since v1.5.1
--------------------
========================
Updates since v1.5.1
--------------------
+* Plumbing level superproject support.
+
+ You can include a subdirectory that has an independent git
+ repository in your index and tree objects of your project
+ ("superproject"). This plumbing (i.e. "core") level
+ superproject support explicitly excludes recursive behaviour.
+
+ The "subproject" entries in the index and trees of a superproject
+ are incompatible with older versions of git. Experimenting with
+ the plumbing level support is encouraged, but be warned that
+ unless everybody in your project updates to this release or
+ later, using this feature would make your project
+ inaccessible by people with older versions of git.
+
+* Plumbing level gitattributes support.
+
+ The gitattributes mechanism allows you to add 'attributes' to
+ paths in your project, and affect the way certain git
+ operations work. Currently you can influence if a path is
+ considered a binary or text (the former would be treated by
+ 'git diff' not to produce textual output; the latter can go
+ through the line endings conversion process in repositories
+ with core.autocrlf set), expand and unexpand '$Id$' keyword
+ with blob object name, specify a custom 3-way merge driver,
+ and specify a custom diff driver. You can also apply
+ arbitrary filter to contents on check-in/check-out codepath
+ but this feature is an extremely sharp-edged razor and needs
+ to be handled with caution (do not use it unless you
+ understand the earlier mailing list discussion on keyword
+ expansion). These conversions apply when checking files in
+ or out, and exporting via git-archive.
+
+* The packfile format now optionally suports 64-bit index.
+
+ This release supports the "version 2" format of the .idx
+ file. This is automatically enabled when a huge packfile
+ needs more than 32-bit to express offsets of objects in the
+ pack.
+
+* Comes with an updated git-gui 0.7.1
+
+* Updated gitweb:
+
+ - can show combined diff for merges;
+ - uses font size of user's preference, not hardcoded in pixels;
+ - can now 'grep';
+
* New commands and options.
- "git bisect start" can optionally take a single bad commit and

option, to override the built-in "[PATCH]".
- "git format-patch" learned a new --subject-prefix=<string>
option, to override the built-in "[PATCH]".
+ - "git add -u" is a quick way to do the first stage of "git
+ commit -a" (i.e. update the index to match the working
+ tree); it obviously does not make a commit.
+
+ - "git clean" honors a new configuration, "clean.requireforce". When
+ set to true, this makes "git clean" a no-op, preventing you
+ from losing files by typing "git clean" when you meant to
+ say "make clean". You can still say "git clean -f" to
+ override this.
+
+ - "git log" family of commands learned --date={local,relative,default}
+ option. --date=relative is synonym to the --relative-date.
+ --date=local gives the timestamp in local timezone.
+
* Updated behavior of existing commands.

+ - When $GIT_COMMITTER_EMAIL or $GIT_AUTHOR_EMAIL is not set
+ but $EMAIL is set, the latter is used as a substitute.

- "git diff --stat" shows size of preimage and postimage blobs
for binary contents. Earlier it only said "Bin".

- "git archive" does not insist you to give --format parameter
anymore; it defaults to "tar".
- "git archive" does not insist you to give --format parameter
anymore; it defaults to "tar".
+ - "git cvsserver" can use backends other than sqlite.
+
+ - "gitview" (in contrib/ section) learned to better support
+ "git-annotate".
+
+ - "git diff $commit1:$path2 $commit2:$path2" can now report
+ mode changes between the two blobs.
+
+ - Local "git fetch" from a repository whose object store is
+ one of the alternates (e.g. fetching from the origin in a
+ repository created with "git clone -l -s") avoids
+ downloading objects unnecessarily.
+
+ - "git blame" uses .mailmap to canonicalize the author name
+ just like "git shortlog" does.
+
+ - "git pack-objects" pays attention to pack.depth
+ configuration variable.
+
+ - "git cherry-pick" and "git revert" does not use .msg file in
+ the working tree to prepare commit message; instead it uses
+ $GIT_DIR/MERGE_MSG as other commands do.

-Fixes since v1.5.1
-------------------
-
-The following are all in v1.5.1.x series, unless otherwise noted.
-
-* Documentation updates
-
- - Various documentation updates from J. Bruce Fields, Frank
- Lichtenheld, Alex Riesen and others. Andrew Ruder started a
- war on undocumented options.
-
-* Bugfixes
+ - The recursive merge strategy updated a worktree file that
+ was changed identically in two branches, when one of them
+ renamed it. We do not do that when there is no rename, so
+ match that behaviour. This avoids excessive rebuilds.
- - "git diff a/ b/" incorrectly fell in "diff between two
- filesystem objects" codepath, when the user most likely
- wanted to limit the extent of output to two tracked
- directories.
+ - The default pack depth has been increased to 50, as the
+ recent addition of delta_base_cache makes deeper delta chains
+ much less expensive to access. Depending on the project, it was
+ reported that this reduces the resulting pack file by 10%
+ or so.
- - git-quiltimport had the same bug as we fixed for
- git-applymbox in v1.5.1.1 -- it gave an alarming "did not
- have any patch" message (but did not actually fail and was
- harmless).
- - various git-svn fixes.
+Fixes since v1.5.1
+------------------
- - Sample update hook incorrectly always refused requests to
- delete branches through push.
+All of the fixes in v1.5.1 maintenance series are included in
+this release, unless otherwise noted.
- - git-blame on a very long working tree path had buffer
- overrun problem.

a path changes from a file to a directory between the

will not be backported to 1.5.1.x series, as it is rather an
intrusive change.
-* Performance Tweaks
+ - git-fetch had trouble with a remote with insanely large number
+ of refs.
+
+ - "git clean -d -X" now does not remove non-excluded directories.
