   1Git v2.7.1 Release Notes
   2========================
   3
   4Fixes since v2.7
   5----------------
   6
   7 * An earlier change in 2.5.x-era broke users' hooks and aliases by
   8   exporting GIT_WORK_TREE to point at the root of the working tree,
   9   interfering when they tried to use a different working tree without
  10   setting GIT_WORK_TREE environment themselves.
  11
  12 * The "exclude_list" structure has the usual "alloc, nr" pair of
  13   fields to be used by ALLOC_GROW(), but clear_exclude_list() forgot
  14   to reset 'alloc' to 0 when it cleared 'nr' to discard the managed
  15   array.
  16
  17 * "git send-email" was confused by escaped quotes stored in the alias
  18   files saved by "mutt", which has been corrected.
  19
  20 * A few unportable C construct have been spotted by clang compiler
  21   and have been fixed.
  22
  23 * The documentation has been updated to hint the connection between
  24   the '--signoff' option and DCO.
  25
  26 * "git reflog" incorrectly assumed that all objects that used to be
  27   at the tip of a ref must be commits, which caused it to segfault.
  28
  29 * The ignore mechanism saw a few regressions around untracked file
  30   listing and sparse checkout selection areas in 2.7.0; the change
  31   that is responsible for the regression has been reverted.
  32
  33 * Some codepaths used fopen(3) when opening a fixed path in $GIT_DIR
  34   (e.g. COMMIT_EDITMSG) that is meant to be left after the command is
  35   done.  This however did not work well if the repository is set to
  36   be shared with core.sharedRepository and the umask of the previous
  37   user is tighter.  They have been made to work better by calling
  38   unlink(2) and retrying after fopen(3) fails with EPERM.
  39
  40 * Asking gitweb for a nonexistent commit left a warning in the server
  41   log.
  42
  43 * "git rebase", unlike all other callers of "gc --auto", did not
  44   ignore the exit code from "gc --auto".
  45
  46 * Many codepaths that run "gc --auto" before exiting kept packfiles
  47   mapped and left the file descriptors to them open, which was not
  48   friendly to systems that cannot remove files that are open.  They
  49   now close the packs before doing so.
  50
  51 * A recent optimization to filter-branch in v2.7.0 introduced a
  52   regression when --prune-empty filter is used, which has been
  53   corrected.
  54
  55 * The description for SANITY prerequisite the test suite uses has
  56   been clarified both in the comment and in the implementation.
  57
  58 * "git tag" started listing a tag "foo" as "tags/foo" when a branch
  59   named "foo" exists in the same repository; remove this unnecessary
  60   disambiguation, which is a regression introduced in v2.7.0.
  61
  62 * The way "git svn" uses auth parameter was broken by Subversion
  63   1.9.0 and later.
  64
  65 * The "split" subcommand of "git subtree" (in contrib/) incorrectly
  66   skipped merges when it shouldn't, which was corrected.
  67
  68 * A few options of "git diff" did not work well when the command was
  69   run from a subdirectory.
  70
  71 * dirname() emulation has been added, as Msys2 lacks it.
  72
  73 * The underlying machinery used by "ls-files -o" and other commands
  74   have been taught not to create empty submodule ref cache for a
  75   directory that is not a submodule.  This removes a ton of wasted
  76   CPU cycles.
  77
  78 * Drop a few old "todo" items by deciding that the change one of them
  79   suggests is not such a good idea, and doing the change the other
  80   one suggested to do.
  81
  82 * Documentation for "git fetch --depth" has been updated for clarity.
  83
  84 * The command line completion learned a handful of additional options
  85   and command specific syntax.
  86
  87Also includes a handful of documentation and test updates.
