   1 Git v1.7.6 Release Notes
   2 ========================
   3
   4 Updates since v1.7.5
   5 --------------------
   6
   7  * Various git-svn updates.
   8
   9  * Updates the way content tags are handled in gitweb.  Also adds
  10    a UI to choose common timezone for displaying the dates.
  11
  12  * Similar to branch names, tagnames that begin with "-" are now
  13    disallowed.
  14
  15  * Clean-up of the C part of i18n (but not l10n---please wait)
  16    continues.
  17
  18  * The scripting part of the codebase is getting prepared for i18n/l10n.
  19
  20  * Pushing and pulling from a repository with large number of refs that
  21    point to identical commits are optimized by not listing the same commit
  22    during the common ancestor negotiation exchange with the other side.
  23
  24  * Adding a file larger than core.bigfilethreshold (defaults to 1/2 Gig)
  25    using "git add" will send the contents straight to a packfile without
  26    having to hold it and its compressed representation both at the same
  27    time in memory.
  28
  29  * Processes spawned by "[alias] <name> = !process" in the configuration
  30    can inspect GIT_PREFIX environment variable to learn where in the
  31    working tree the original command was invoked.
  32
  33  * A magic pathspec ":/" tells a command that limits its operation to
  34    the current directory when ran from a subdirectory to work on the
  35    entire working tree. In general, ":/path/to/file" would be relative
  36    to the root of the working tree hierarchy.
  37
  38    After "git reset --hard; edit Makefile; cd t/", "git add -u" would
  39    be a no-op, but "git add -u :/" would add the updated contents of
  40    the Makefile at the top level. If you want to name a path in the
  41    current subdirectory whose unusual name begins with ":/", you can
  42    name it by "./:/that/path" or by "\:/that/path".
  43
  44  * "git blame" learned "--abbrev[=<n>]" option to control the minimum
  45    number of hexdigits shown for commit object names.
  46
  47  * "git blame" learned "--line-porcelain" that is less efficient but is
  48    easier to parse.
  49
  50  * Aborting "git commit --interactive" discards updates to the index
  51    made during the interactive session.
  52
  53  * "git commit" learned a "--patch" option to directly jump to the
  54    per-hunk selection UI of the interactive mode.
  55
  56  * "git diff" and its family of commands learned --dirstat=0 to show
  57    directories that contribute less than 0.1% of changes.
  58
  59  * "git diff" and its family of commands learned --dirstat=lines mode to
  60    assess damage to the directory based on number of lines in the patch
  61    output, not based on the similarity numbers.
  62
  63  * "git format-patch" learned "--quiet" option to suppress the output of
  64    the names of generated files.
  65
  66  * "git format-patch" quotes people's names when it has RFC822 special
  67    characters in it, e.g. "Junio C. Hamano" <jch@example.com>.  Earlier
  68    it was up to the user to do this when using its output.
  69
  70  * "git format-patch" can take an empty --subject-prefix now.
  71
  72  * "git grep" learned the "-P" option to take pcre regular expressions.
  73
  74  * "git log" and friends learned a new "--notes" option to replace the
  75    "--show-notes" option.  Unlike "--show-notes", "--notes=<ref>" does
  76    not imply showing the default notes.
  77
  78  * They also learned a log.abbrevCommit configuration variable to augment
  79    the --abbrev-commit command line option.
  80
  81  * "git ls-remote" learned "--exit-code" option to consider it a
  82    different kind of error when no remote ref to be shown.
  83
  84  * "git merge" learned "-" as a short-hand for "the previous branch", just
  85    like the way "git checkout -" works.
  86
  87  * "git merge" uses "merge.ff" configuration variable to decide to always
  88    create a merge commit (i.e. --no-ff, aka merge.ff=no), refuse to create
  89    a merge commit (i.e. --ff-only, aka merge.ff=only). Setting merge.ff=yes
  90    (or not setting it at all) restores the default behaviour of allowing
  91    fast-forward to happen when possible.
  92
  93  * p4-import (from contrib) learned a new option --preserve-user.
  94
  95  * "git read-tree -m" learned "--dry-run" option that reports if a merge
  96    would fail without touching the index nor the working tree.
  97
  98  * "git rebase" that does not specify on top of which branch to rebase
  99    the current branch now uses @{upstream} of the current branch.
 100
 101  * "git rebase" finished either normally or with --abort did not
 102    update the reflog for HEAD to record the event to come back to
 103    where it started from.
 104
 105  * "git remote add -t only-this-branch --mirror=fetch" is now allowed. Earlier
 106    a fetch-mode mirror meant mirror everything, but now it only means refs are
 107    not renamed.
 108
 109  * "git rev-list --count" used with "--cherry-mark" counts the cherry-picked
 110    commits separately, producing more a useful output.
 111
 112  * "git submodule update" learned "--force" option to get rid of local
 113    changes in submodules and replace them with the up-to-date version.
 114
 115  * "git status" and friends ignore .gitmodules file while the file is
 116    still in a conflicted state during a merge, to avoid using information
 117    that is not final and possibly corrupt with conflict markers.
 118
 119 Also contains various documentation updates and minor miscellaneous
 120 changes.
