+GIT v1.5.2 Release Notes
========================
Updates since v1.5.1
--------------------
-* Plumbing level subproject support.
+* Plumbing level superproject support.
You can include a subdirectory that has an independent git

- "subproject". This plumbing (i.e. "core") level subproject
- support explicitly excludes recursive behaviour.

+ 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
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), and specify a custom 3-way merge

+ 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
+ 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.
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".
- "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 unnecessary.
+ 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.
* Builds
- gitk and git-gui can be configured out.
- Generated documentation pages automatically get version
- information from GIT_VERSION
+ information from GIT_VERSION.
- Parallel build with "make -j" descending into subdirectory
was fixed.
* Performance Tweaks
- - optimized "git-rev-list --bisect" (hence "git-bisect").
+ - Optimized "git-rev-list --bisect" (hence "git-bisect").
- - optimized "git-add $path" in a large directory, most of
+ - Optimized "git-add $path" in a large directory, most of
whose contents are ignored.
+ - Optimized "git-diff-tree" for reduced memory footprint.
+
+ - 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.
+
+ - 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.
+
Fixes since v1.5.1
------------------
will not be backported to 1.5.1.x series, as it is rather an
intrusive change.
-* Documentation updates
+ - git-fetch had trouble with a remote with insanely large number
+ of refs.
-* Performance Tweaks
+ - "git clean -d -X" now does not remove non-excluded directories.
