Alternatively, you + can give the "--no-edit" option to individual invocations of the + "git merge" command if you know everybody who uses your script has + Git v1.7.8 or newer. + + * The "--binary/-b" options to "git am" have been a no-op for quite a + while and were deprecated in mid 2008 (v1.6.0). When you give these + options to "git am", it will now warn and ask you not to use them. + + * When you do not tell which branches and tags to push to the "git + push" command in any way, the command used "matching refs" rule to + update remote branches and tags with branches and tags with the + same name you locally have. In future versions of Git, this will + change to push out only your current branch according to either the + "upstream" or the "current" rule. Although "upstream" may be more + powerful once the user understands Git better, the semantics + "current" gives is simpler and easier to understand for beginners + and may be a safer and better default option. We haven't decided + yet which one to switch to. + + +Updates since v1.7.9 +-------------------- + +UI, Workflows & Features + + * various "gitk" updates. + - show the path to the top level directory in the window title + - update preference edit dialog + - display file list correctly when directories are given on command line + - make "git-describe" output in the log message into a clickable link + - avoid matching the UNIX timestamp part when searching all fields + - give preference to symbolic font names like sans & monospace + - allow comparing two commits using a mark + - "gitk" honors log.showroot configuration. + + * Teams for localizing the messages from the Porcelain layer of + commands are starting to form, thanks to Jiang Xin who volunteered + to be the localization coordinator. Translated messages for + simplified Chinese, Swedish and Portuguese are available. + + * The configuration mechanism learned an "include" facility; an + assignment to the include.path pseudo-variable causes the named + file to be included in-place when Git looks up configuration + variables. + + * A content filter (clean/smudge) used to be just a way to make the + recorded contents "more useful", and allowed to fail; a filter can + now optionally be marked as "required". + + * Options whose names begin with "--no-" (e.g. the "--no-verify" + option of the "git commit" command) can be negated by omitting + "no-" from its name, e.g. "git commit --verify". + + * "git am" learned to pass "-b" option to underlying "git mailinfo", so + that a bracketed string other than "PATCH" at the beginning can be kept. + + * "git clone" learned "--single-branch" option to limit cloning to a + single branch (surprise!); tags that do not point into the history + of the branch are not fetched. + + * "git clone" learned to detach the HEAD in the resulting repository + when the user specifies a tag with "--branch" (e.g., "--branch=v1.0"). + Clone also learned to print the usual "detached HEAD" advice in such + a case, similar to "git checkout v1.0". + + * When showing a patch while ignoring whitespace changes, the context + lines are taken from the postimage, in order to make it easier to + view the output. + + * "git diff --stat" learned to adjust the width of the output on + wider terminals, and give more columns to pathnames as needed. + + * "diff-highlight" filter (in contrib/) was updated to produce more + aesthetically pleasing output. + + * "fsck" learned "--no-dangling" option to omit dangling object + information. + + * "git log -G" and "git log -S" learned to pay attention to the "-i" + option. With "-i", "log -G" ignores the case when finding patch + hunks that introduce or remove a string that matches the given + pattern. Similarly with "-i", "log -S" ignores the case when + finding the commit the given block of text appears or disappears + from the file. + + * "git merge" in an interactive session learned to spawn the editor + by default to let the user edit the auto-generated merge message, + to encourage people to explain their merges better. Legacy scripts + can export GIT_MERGE_AUTOEDIT=no to retain the historical behavior. + Both "git merge" and "git pull" can be given --no-edit from the + command line to accept the auto-generated merge message. + + * The advice message given when the user didn't give enough clue on + what to merge to "git pull" and "git merge" has been updated to + be more concise and easier to understand. + + * "git push" learned the "--prune" option, similar to "git fetch". + + * The whole directory that houses a top-level superproject managed by + "git submodule" can be moved to another place. + + * "git symbolic-ref" learned the "--short" option to abbreviate the + refname it shows unambiguously. + + * "git tag --list" can be given "--points-at <object>" to limit its + output to those that point at the given object. + + * "gitweb" allows intermediate entries in the directory hierarchy + that leads to a project to be clicked, which in turn shows the + list of projects inside that directory. + + * "gitweb" learned to read various pieces of information for the + repositories lazily, instead of reading everything that could be + needed (including the ones that are not necessary for a specific + task). + + * Project search in "gitweb" shows the substring that matched in the + project name and description highlighted. + + * HTTP transport learned to authenticate with a proxy if needed. + + * A new script "diffall" is added to contrib/; it drives an + external tool to perform a directory diff of two Git revisions + in one go, unlike "difftool" that compares one file at a time. + +Foreign Interface + + * Improved handling of views, labels and branches in "git-p4" (in contrib). + + * "git-p4" (in contrib) suffered from unnecessary merge conflicts when + p4 expanded the embedded $RCS$-like keywords; it can be now told to + unexpand them. + + * Some "git-svn" updates. + + * "vcs-svn"/"svn-fe" learned to read dumps with svn-deltas and + support incremental imports. + + * "git difftool/mergetool" learned to drive DeltaWalker. + +Performance + + * Unnecessary calls to parse_object() "git upload-pack" makes in + response to "git fetch", have been eliminated, to help performance + in repositories with excessive number of refs. + +Internal Implementation (please report possible regressions) + + * Recursive call chains in "git index-pack" to deal with long delta + chains have been flattened, to reduce the stack footprint. + + * Use of add_extra_ref() API is now gone, to make it possible to + cleanly restructure the overall refs API. + + * The command line parser of "git pack-objects" now uses parse-options + API. + + * The test suite supports the new "test_pause" helper function. + + * Parallel to the test suite, there is a beginning of performance + benchmarking framework. + + * t/Makefile is adjusted to prevent newer versions of GNU make from + running tests in seemingly random order. + + * The code to check if a path points at a file beyond a symbolic link + has been restructured to be thread-safe. + + * When pruning directories that has become empty during "git prune" + and "git prune-packed", call closedir() that iterates over a + directory before rmdir() it. + +Also contains minor documentation updates and code clean-ups. + + +Fixes since v1.7.9 +------------------ + +Unless otherwise noted, all the fixes since v1.7.9 in the maintenance +releases are contained in this release (see release notes to them for +details). + + * Build with NO_PERL_MAKEMAKER was broken and Git::I18N did not work + with versions of Perl older than 5.8.3. + (merge 5eb660e ab/perl-i18n later to maint). + + * "git tag -s" honored "gpg.program" configuration variable since + 1.7.9, but "git tag -v" and "git verify-tag" didn't. + (merge a2c2506 az/verify-tag-use-gpg-config later to maint). + + * "configure" script learned to take "--with-sane-tool-path" from the + command line to record SANE_TOOL_PATH (used to avoid broken platform + tools in /usr/bin) in config.mak.autogen.
