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 supports 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 + zero or more good commits on the command line. + + - "git shortlog" can optionally be told to wrap its output. + + - "subtree" merge strategy allows another project to be merged in as + your subdirectory. + + - "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 lost-found" shows stuff that are unreachable except + from reflogs. + + - "git checkout branch^0" now detaches HEAD at the tip commit + on the named branch, instead of just switching to the + branch (use "git checkout branch" to switch to the branch, + as before). + + - "git bisect next" can be used after giving only a bad commit + without giving a good one (this starts bisection half-way to + the root commit). We used to refuse to operate without a + good and a bad commit. + + - "git push", when pushing into more than one repository, does + not stop at the first error. + + - "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. + +* Builds + + - git-p4import has never been installed; now there is an + installation option to do so. + + - gitk and git-gui can be configured out. + + - Generated documentation pages automatically get 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-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 +------------------ + +All of the fixes in v1.5.1 maintenance series are included in +this release, unless otherwise noted. + +* Bugfixes + + - Switching branches with "git checkout" refused to work when + a path changes from a file to a directory between the + current branch and the new branch, in order not to lose + possible local changes in the directory that is being turned + into a file with the switch. We now allow such a branch + switch after making sure that there is no locally modified + file nor un-ignored file in the directory. This has not + been backported to 1.5.1.x series, as it is rather an + intrusive change. + + - Merging branches that have a file in one and a directory in + another at the same path used to get quite confused. We + handle such a case a bit more carefully, even though that is + still left as a conflict for the user to sort out. This + will not be backported to 1.5.1.x series, as it is rather an + intrusive change. + + - git-fetch had trouble with a remote with insanely large number + of refs. + + - "git clean -d -X" now does not remove non-excluded directories. + + - rebasing (without -m) a series that changes a symlink to a directory + in the middle of a path confused git-apply greatly and refused to + operate. |
