   1Git v1.7.7 Release Notes
   2========================
   3
   4Updates since v1.7.6
   5--------------------
   6
   7 * The scripting part of the codebase is getting prepared for i18n/l10n.
   8
   9 * Interix, Cygwin and Minix ports got updated.
  10
  11 * Various updates to git-p4 (in contrib/), fast-import, and git-svn.
  12
  13 * Gitweb learned to read from /etc/gitweb-common.conf when it exists,
  14   before reading from gitweb_config.perl or from /etc/gitweb.conf
  15   (this last one is read only when per-repository gitweb_config.perl
  16   does not exist).
  17
  18 * Various codepaths that invoked zlib deflate/inflate assumed that these
  19   functions can compress or uncompress more than 4GB data in one call on
  20   platforms with 64-bit long, which has been corrected.
  21
  22 * Git now recognizes loose objects written by other implementations that
  23   use a non-standard window size for zlib deflation (e.g. Agit running on
  24   Android with 4kb window). We used to reject anything that was not
  25   deflated with 32kb window.
  26
  27 * Interaction between the use of pager and coloring of the output has
  28   been improved, especially when a command that is not built-in was
  29   involved.
  30
  31 * "git am" learned to pass the "--exclude=<path>" option through to underlying
  32   "git apply".
  33
  34 * You can now feed many empty lines before feeding an mbox file to
  35   "git am".
  36
  37 * "git archive" can be told to pass the output to gzip compression and
  38   produce "archive.tar.gz".
  39
  40 * "git bisect" can be used in a bare repository (provided that the test
  41   you perform per each iteration does not need a working tree, of
  42   course).
  43
  44 * The length of abbreviated object names in "git branch -v" output
  45   now honors the core.abbrev configuration variable.
  46
  47 * "git check-attr" can take relative paths from the command line.
  48
  49 * "git check-attr" learned an "--all" option to list the attributes for a
  50   given path.
  51
  52 * "git checkout" (both the code to update the files upon checking out a
  53   different branch and the code to checkout a specific set of files) learned
  54   to stream the data from object store when possible, without having to
  55   read the entire contents of a file into memory first. An earlier round
  56   of this code that is not in any released version had a large leak but
  57   now it has been plugged.
  58
  59 * "git clone" can now take a "--config key=value" option to set the
  60   repository configuration options that affect the initial checkout.
  61
  62 * "git commit <paths>..." now lets you feed relative pathspecs that
  63   refer to outside your current subdirectory.
  64
  65 * "git diff --stat" learned a --stat-count option to limit the output of
  66   a diffstat report.
  67
  68 * "git diff" learned a "--histogram" option to use a different diff
  69   generation machinery stolen from jgit, which might give better
  70   performance.
  71
  72 * "git diff" had a weird worst case behaviour that can be triggered
  73   when comparing files with potentially many places that could match.
  74
  75 * "git fetch", "git push" and friends no longer show connection
  76   errors for addresses that couldn't be connected to when at least one
  77   address succeeds (this is arguably a regression but a deliberate
  78   one).
  79
  80 * "git grep" learned "--break" and "--heading" options, to let users mimic
  81   the output format of "ack".
  82
  83 * "git grep" learned a "-W" option that shows wider context using the same
  84   logic used by "git diff" to determine the hunk header.
  85
  86 * Invoking the low-level "git http-fetch" without "-a" option (which
  87   git itself never did--normal users should not have to worry about
  88   this) is now deprecated.
  89
  90 * The "--decorate" option to "git log" and its family learned to
  91   highlight grafted and replaced commits.
  92
  93 * "git rebase master topci" no longer spews usage hints after giving
  94   the "fatal: no such branch: topci" error message.
  95
  96 * The recursive merge strategy implementation got a fairly large
  97   fix for many corner cases that may rarely happen in real world
  98   projects (it has been verified that none of the 16000+ merges in
  99   the Linux kernel history back to v2.6.12 is affected with the
 100   corner case bugs this update fixes).
 101
 102 * "git stash" learned an "--include-untracked option".
 103
 104 * "git submodule update" used to stop at the first error updating a
 105   submodule; it now goes on to update other submodules that can be
 106   updated, and reports the ones with errors at the end.
 107
 108 * "git push" can be told with the "--recurse-submodules=check" option to
 109   refuse pushing of the supermodule, if any of its submodules'
 110   commits hasn't been pushed out to their remotes.
 111
 112 * "git upload-pack" and "git receive-pack" learned to pretend that only a
 113   subset of the refs exist in a repository. This may help a site to
 114   put many tiny repositories into one repository (this would not be
 115   useful for larger repositories as repacking would be problematic).
 116
 117 * "git verify-pack" has been rewritten to use the "index-pack" machinery
 118   that is more efficient in reading objects in packfiles.
 119
 120 * test scripts for gitweb tried to run even when CGI-related perl modules
 121   are not installed; they now exit early when the latter are unavailable.
 122
 123Also contains various documentation updates and minor miscellaneous
 124changes.

 126
 127Fixes since v1.7.6
 128------------------
 129
 130Unless otherwise noted, all fixes in the 1.7.6.X maintenance track are
 131included in this release.
 132
 133 * "git branch -m" and "git checkout -b" incorrectly allowed the tip
 134   of the branch that is currently checked out updated.
