   1Git v1.7.5 Release Notes
   2========================
   3
   4Updates since v1.7.4
   5--------------------
   6
   7 * Various MinGW portability fixes.
   8
   9 * Various git-p4 enhancements (in contrib).
  10
  11 * Various vcs-svn, git-svn and gitk enhancements and fixes.
  12
  13 * Various git-gui updates (0.14.0).
  14
  15 * Update to more modern HP-UX port.
  16
  17 * The codebase is getting prepared for i18n/l10n; no translated
  18   strings nor translation mechanism in the code yet, but the strings
  19   are being marked for l10n.
  20
  21 * The bash completion script can now complete symmetric difference
  22   for "git diff" command, e.g. "git diff ...bra<TAB>".
  23
  24 * The default minimum length of abbreviated and unique object names
  25   can now be configured by setting the core.abbrev configuration
  26   variable.
  27
  28 * "git apply -v" reports offset lines when the patch does not apply at
  29   the exact location recorded in the diff output.
  30
  31 * "git config" used to be also known as "git repo-config", but the old
  32   name is now officially deprecated.
  33
  34 * "git checkout --detach <commit>" is a more user friendly synonym for
  35   "git checkout <commit>^0".
  36
  37 * "git checkout" performed on detached HEAD gives a warning and
  38   advice when the commit being left behind will become unreachable from
  39   any branch or tag.
  40
  41 * "git cherry-pick" and "git revert" can be told to use a custom merge
  42   strategy, similar to "git rebase".
  43
  44 * "git cherry-pick" remembers which commit failed to apply when it is
  45   stopped by conflicts, making it unnecessary to use "commit -c $commit"
  46   to conclude it.
  47
  48 * "git cvsimport" bails out immediately when the cvs server cannot be
  49   reached, without spewing unnecessary error messages that complain about
  50   the server response it never got.
  51
  52 * "git fetch" vs "git upload-pack" transfer learned 'no-done'
  53   protocol extension to save one round-trip after the content
  54   negotiation is done. This saves one HTTP RPC, reducing the overall
  55   latency for a trivial fetch.
  56
  57 * "git fetch" can be told to recursively fetch submodules on-demand.
  58
  59 * "git grep -f <filename>" learned to treat "-" as "read from the
  60   standard input stream".
  61
  62 * "git grep --no-index" did not honor pathspecs correctly, returning
  63   paths outside the specified area.
  64
  65 * "git init" learned the --separate-git-dir option to allow the git
  66   directory for a new repository created elsewhere and linked via the
  67   gitdir mechanism. This is primarily to help submodule support later
  68   to switch between a branch of superproject that has the submodule
  69   and another that does not.
  70
  71 * "git log" type commands now understand globbing pathspecs.  You
  72   can say "git log -- '*.txt'" for example.
  73
  74 * "git log" family of commands learned --cherry and --cherry-mark
  75   options that can be used to view two diverged branches while omitting
  76   or highlighting equivalent changes that appear on both sides of a
  77   symmetric difference (e.g. "log --cherry A...B").
  78
  79 * A lazy "git merge" that didn't say what to merge used to be an error.
  80   When run on a branch that has an upstream defined, however, the command
  81   now merges from the configured upstream.
  82
  83 * "git mergetool" learned how to drive "beyond compare 3" as well.
  84
  85 * "git rerere forget" without pathspec used to forget all the saved
  86   conflicts that relate to the current merge; it now requires you to
  87   give it pathspecs.
  88
  89 * "git rev-list --objects $revs -- $pathspec" now limits the objects listed
  90   in its output properly with the pathspec, in preparation for narrow
  91   clones.
  92
  93 * "git push" with no parameters gives better advice messages when
  94   "tracking" is used as the push.default semantics or there is no remote
  95   configured yet.
  96
  97 * A possible value to the "push.default" configuration variable,
  98   'tracking', gained a synonym that more naturally describes what it
  99   does, 'upstream'.
 100
 101 * "git rerere" learned a new subcommand "remaining" that is similar to
 102   "status" and lists the paths that had conflicts which are known to
 103   rerere, but excludes the paths that have already been marked as
 104   resolved in the index from its output.  "git mergetool" has been
 105   updated to use this facility.
 106
 107Also contains various documentation updates.

 110Fixes since v1.7.4
 111------------------
 112
 113All of the fixes in the v1.7.4.X maintenance series are included in this
 114release, unless otherwise noted.
 115
 116 * "git fetch" from a client that is mostly following the remote
 117   needlessly told all of its refs to the server for both sides to
 118   compute the set of objects that need to be transferred efficiently,
 119   instead of stopping when the server heard enough. In a project with
 120   many tags, this turns out to be extremely wasteful, especially over
 121   the smart HTTP transport (sp/maint-{upload,fetch}-pack-stop-early~1).
 122
 123 * "git fetch" run from a repository that uses the same repository as
 124   its alternate object store as the repository it is fetching from
 125   did not tell the server that it already has access to objects
 126   reachable from the refs in their common alternate object store,
 127   causing it to fetch unnecessary objects (jc/maint-fetch-alt).
 128
 129 * "git remote add --mirror" created a configuration that is suitable for
 130   doing both a mirror fetch and a mirror push at the same time, which
 131   made little sense.  We now warn and require the command line to specify
 132   either --mirror=fetch or --mirror=push.
