   4Updates since v2.5

   7UI, Workflows & Features
   8
   9 * An asterisk as a substring (as opposed to the entirety) of a path
  10   component for both side of a refspec, e.g.
  11   "refs/heads/o*:refs/remotes/heads/i*", is now allowed.
  12
  13 * New userdiff pattern definition for fountain screenwriting markup
  14   format has been added.
  15
  16 * "git log" and friends learned a new "--date=format:..." option to
  17   format timestamps using system's strftime(3).
  18
  19 * "git fast-import" learned to respond to the get-mark command via
  20   its cat-blob-fd interface.
  21
  22 * "git rebase -i" learned "drop commit-object-name subject" command
  23   as another way to skip replaying of a commit.
  24
  25 * A new configuration variable can enable "--follow" automatically
  26   when "git log" is run with one pathspec argument.
  27
  28 * "git status" learned to show a more detailed information regarding
  29   the "rebase -i" session in progress.
  30
  31 * "git cat-file" learned "--batch-all-objects" option to enumerate all
  32   available objects in the repository more quickly than "rev-list
  33   --all --objects" (the output includes unreachable objects, though).
  34
  35 * "git fsck" learned to ignore errors on a set of known-to-be-bad
  36   objects, and also allows the warning levels of various kinds of
  37   non-critical breakages to be tweaked.
  38
  39 * "git rebase -i"'s list of todo is made configurable.
  40
  41 * "git send-email" now performs alias-expansion on names that are
  42   given via --cccmd, etc.
  43
  44 * An environment variable GIT_REPLACE_REF_BASE tells Git to look into
  45   refs hierarchy other than refs/replace/ for the object replacement
  46   data.
  47
  48
  49Performance, Internal Implementation, Development Support etc.
  50
  51 * In preparation for allowing different "backends" to store the refs
  52   in a way different from the traditional "one ref per file in
  53   $GIT_DIR or in a $GIT_DIR/packed-refs file" filesystem storage,
  54   direct filesystem access to ref-like things like CHERRY_PICK_HEAD
  55   from scripts and programs has been reduced.
  56
  57 * Computation of untracked status indicator by bash prompt
  58   script (in contrib/) has been optimized.
  59
  60 * Memory use reduction when commit-slab facility is used to annotate
  61   sparsely (which is not recommended in the first place).
  62
  63 * Clean up refs API and make "git clone" less intimate with the
  64   implementation detail.
  65
  66 * "git pull" was reimplemented in C.
  67
  68 * The packet tracing machinery allows to capture an incoming pack
  69   data to a file for debugging.
  70
  71 * Move machinery to parse human-readable scaled numbers like 1k, 4M,
  72   and 2G as an option parameter's value from pack-objects to
  73   parse-options API, to make it available to other codepaths.
  74
  75 * "git verify-tag" and "git verify-commit" have been taught to share
  76   more code, and then learned to optionally show the verification
  77   message from the underlying GPG implementation.
  78
  79 * Various enhancements around "git am" reading patches generated by
  80   foreign SCM have been made.
  81
  82 * Ref listing by "git branch -l" and "git tag -l" commands has
  83   started to be rebuilt, based on the for-each-ref machinery.
  84
  85
  86Also contains various documentation updates and code clean-ups.

  89Fixes since v2.5
  90----------------
  91
  92Unless otherwise noted, all the fixes since v2.5 in the maintenance
  93track are contained in this release (see the maintenance releases'
  94notes for details).
  95
  96 * "git subtree" (in contrib/) depended on "git log" output to be
  97   stable, which was a no-no.  Apply a workaround to force a
  98   particular date format.
  99   (merge e7aac44 da/subtree-date-confusion later to maint).
 100
 101 * An attempt to delete a ref by pushing into a repositorywhose HEAD
 102   symbolic reference points at an unborn branch that cannot be
 103   created due to ref D/F conflict (e.g. refs/heads/a/b exists, HEAD
 104   points at refs/heads/a) failed.
 105   (merge b112b14 jx/do-not-crash-receive-pack-wo-head later to maint).
 106
 107 * The low-level "git send-pack" did not honor 'user.signingkey'
 108   configuration variable when sending a signed-push.
 109   (merge d830d39 db/send-pack-user-signingkey later to maint).
 110
 111 * "sparse checkout" misbehaved for a path that is excluded from the
 112   checkout when switching between branches that differ at the path.
 113   (merge 7d78241 as/sparse-checkout-removal later to maint).
 114
 115 * An experimental "untracked cache" feature used uname(2) in a
 116   slightly unportable way.
 117   (merge 100e433 cb/uname-in-untracked later to maint).
 118
 119 * A "rebase" replays changes of the local branch on top of something
 120   else, as such they are placed in stage #3 and referred to as
 121   "theirs", while the changes in the new base, typically a foreign
 122   work, are placed in stage #2 and referred to as "ours".  Clarify
 123   the "checkout --ours/--theirs".
 124   (merge f303016 se/doc-checkout-ours-theirs later to maint).
 125
 126 * The "rev-parse --parseopt" mode parsed the option specification
 127   and the argument hint in a strange way to allow '=' and other
 128   special characters in the option name while forbidding them from
 129   the argument hint.  This made it impossible to define an option
 130   like "--pair <key>=<value>" with "pair=key=value" specification,
 131   which instead would have defined a "--pair=key <value>" option.
 132   (merge 2d893df ib/scripted-parse-opt-better-hint-string later to maint).
 133
 134 * Often a fast-import stream builds a new commit on top of the
 135   previous commit it built, and it often unconditionally emits a
 136   "from" command to specify the first parent, which can be omitted in
 137   such a case.  This caused fast-import to forget the tree of the
 138   previous commit and then re-read it from scratch, which was
 139   inefficient.  Optimize for this common case.
 140   (merge 0df3245 mh/fast-import-optimize-current-from later to maint).
 141
 142 * Running an aliased command from a subdirectory when the .git thing
 143   in the working tree is a gitfile pointing elsewhere did not work.
 144   (merge d95138e nd/export-worktree later to maint).
 145
 146 * "Is this subdirectory a separate repository that should not be
 147   touched?" check "git clean" was inefficient.  This was replaced
 148   with a more optimized check.
 149   (merge 38ae878 ee/clean-remove-dirs later to maint).
 150
 151 * Code cleanups and documentation updates.
 152   (merge 1c601af es/doc-clean-outdated-tools later to maint).
 153   (merge 3581304 kn/tag-doc-fix later to maint).
 154   (merge 3a59e59 kb/i18n-doc later to maint).
