   1GIT v1.6.1 Release Notes
   2========================
   3
   4Updates since v1.6.0
   5--------------------
   6
   7When some commands (e.g. "git log", "git diff") spawn pager internally, we
   8used to make the pager the parent process of the git command that produces
   9output.  This meant that the exit status of the whole thing comes from the
  10pager, not the underlying git command.  We swapped the order of the
  11processes around and you will see the exit code from the command from now
  12on.
  13
  14(subsystems)
  15
  16* gitk can call out to git-gui to view "git blame" output; git-gui in turn
  17  can run gitk from its blame view.
  18
  19* Various git-gui updates including updated translations.
  20
  21* Various gitweb updates from repo.or.cz installation.
  22
  23(portability)
  24
  25* A few test scripts used nonportable "grep" that did not work well on
  26  some platforms, e.g. Solaris.
  27
  28* Sample pre-auto-gc script has OS X support.
  29
  30(performance)
  31
  32* The underlying diff machinery to produce textual output has been
  33  optimized, which would result in faster "git blame" processing.
  34
  35* Most of the test scripts (but not the ones that try to run servers)
  36  can be run in parallel.
  37
  38* Bash completion of refnames in a repository with massive number of
  39  refs has been optimized.
  40
  41* Cygwin port uses native stat/lstat implementations when applicable,
  42  which leads to improved performance.
  43
  44* "git push" pays attention to alternate repositories to avoid sending
  45  unnecessary objects.
  46
  47* "git svn" can rebuild an out-of-date rev_map file.
  48
  49(usability, bells and whistles)
  50
  51* When you mistype a command name, git helpfully suggests what it guesses
  52  you might have meant to say.  help.autocorrect configuration can be set
  53  to a non-zero value to accept the suggestion when git can uniquely
  54  guess.
  55
  56* "git add -N path..." adds the named paths as an empty blob, so that
  57  subsequent "git diff" will show a diff as if they are creation events.
  58
  59* "git apply" learned --include=paths option, similar to the existing
  60  --exclude=paths option.
  61
  62* "git bisect" is careful about a user mistake and suggests testing of
  63  merge base first when good is not a strict ancestor of bad.
  64
  65* "git checkout --track origin/hack" used to be a syntax error.  It now
  66  DWIMs to create a corresponding local branch "hack", i.e. acts as if you
  67  said "git checkout --track -b hack origin/hack".
  68
  69* "git checkout --ours/--theirs" can be used to check out one side of a
  70  conflicting merge during conflict resolution.
  71
  72* "git checkout -m" can be used to recreate the initial conflicted state
  73  during conflict resolution.
  74
  75* "git cherry-pick" can also utilize rerere for conflict resolution.
  76
  77* "git commit --author=$name" can look up author name from existing
  78  commits.
  79
  80* "git count-objects" reports the on-disk footprint for packfiles and
  81  their corresponding idx files.
  82
  83* "git daemon" learned --max-connections=<count> option.
  84
  85* "git diff" learned to mimic --suppress-blank-empty from GNU diff via a
  86  configuration option.
  87
  88* "git diff" learned to put more sensible hunk headers for Python,
  89  HTML and ObjC contents.
  90
  91* "git diff" learned to vary the a/ vs b/ prefix depending on what are
  92  being compared, controlled by diff.mnemonicprefix configuration.
  93
  94* "git diff" learned --dirstat-by-file to count changed files, not number
  95  of lines, when summarizing the global picture.
  96
  97* "git for-each-ref" learned "refname:short" token that gives an
  98  unambiguously abbreviated refname.
  99
 100* "git grep" learned to accept -z similar to GNU grep.
 101
 102* "git help" learned to use GIT_MAN_VIEWER environment variable before
 103  using "man" program.
 104
 105* "git imap-send" can optionally talk SSL.
 106
 107* "git index-pack" is more careful against disk corruption while
 108  completing a thin pack.
 109
 110* "git log --check" and "git log --exit-code" passes their underlying diff
 111  status with their exit status code.
 112
 113* "git log" learned --simplify-merges, a milder variant of --full-history;
 114  "gitk --simplify-merges" is easier to view than with --full-history.
 115
 116* "git log --pretty=format:" learned "%d" format element that inserts
 117  names of tags that point at the commit.
 118
 119* "git merge --squash" and "git merge --no-ff" into an unborn branch are
 120  noticed as user errors.
 121
 122* "git merge -s $strategy" can use a custom built strategy if you have a
 123  command "git-merge-$strategy" on your $PATH.
 124
 125* "git reflog expire branch" can be used in place of "git reflog expire
 126  refs/heads/branch".
 127
 128* "git submodule foreach" subcommand allows you to iterate over checked
 129  out submodules.
 130
 131* "git submodule sync" subcommands allows you to update the origin URL
 132  recorded in submodule directories from the toplevel .gitmodules file.
 133
 134* "git svn branch" can create new branches on the other end.
 135
 136(internal)
 137
 138* "git hash-object" learned to lie about the path being hashed, so that
 139  correct gitattributes processing can be done while hashing contents
 140  stored in a temporary file.
 141
 142* various callers of git-merge-recursive avoid forking it as an external
 143  process.
 144
 145
 146Fixes since v1.6.0
 147------------------
 148
 149All of the fixes in v1.6.0.X maintenance series are included in this
 150release, unless otherwise noted.
 151
 152* "git add" and "git update-index" incorrectly allowed adding S/F when S
 153  is a tracked symlink that points at a directory D that has a path F in
 154  it (we still need to fix a similar nonsense when S is a submodule and F
 155  is a path in it).
 156
 157* "git diff --stdin" used to take two trees on a line and compared them,
 158  but we dropped support for such a use case long time ago.  This has
 159  been resurrected.
 160
 161* Giving 3 or more tree-ish to "git diff" is supposed to show the combined
 162  diff from second and subsequent trees to the first one.  b75271d ("git
 163  diff <tree>{3,}": do not reverse order of arguments, 2008-10-10) needs
 164  to be cherry-picked to 'maint'.
 165
 166* "git filter-branch" failed to rewrite a tag name with slashes in it.
 167
 168* "git push --tags --all $there" failed with generic usage message without
 169  telling saying these two options are incompatible.
 170
 171* "git log --author/--committer" match used to potentially match the
 172  timestamp part, exposing internal implementation detail.  Also these did
 173  not work with --fixed-strings match at all.
