   1Git v1.8.4 Release Notes
   2========================
   3
   4Updates since v1.8.3
   5--------------------
   6
   7Foreign interface
   8
   9 * Remote transport helper has been updated to report errors and
  10   maintain ref hierarchy used to keep track of its own state better.
  11
  12
  13UI, Workflows & Features
  14
  15 * "check-ignore" (new feature since 1.8.2) has been updated to work
  16   more like "check-attr" over bidi-pipes.
  17
  18 * "git describe" learned "--first-parent" option to limit its closest
  19   tagged commmit search to the first-parent chain.
  20
  21 * "git merge foo" that might have meant "git merge origin/foo" is
  22   diagnosed with a more informative error message.
  23
  24 * "git log -L<line>,<range>:<filename>" has been added.  This may
  25   still have leaks and rough edges, though.
  26
  27 * We used the approxidate() parser for "--expire=<timestamp>" options
  28   of various commands, but it is better to treat --expire=all and
  29   --expire=now a bit more specially than using the current timestamp.
  30   "git gc" and "git reflog" have been updated with a new parsing
  31   function for expiry dates.
  32
  33 * Updates to completion (both bash and zsh) helpers.
  34
  35 * "git fetch origin master" unlike "git fetch origin" or "git fetch"
  36   did not update "refs/remotes/origin/master"; this was an early
  37   design decision to keep the update of remote tracking branches
  38   predictable, but in practice it turns out that people find it more
  39   convenient to opportunisticly update them whenever we have a
  40   chance, and we have been updating them when we run "git push" which
  41   already breaks the original "predictability" anyway.
  42
  43
  44Performance, Internal Implementation, etc.
  45
  46 * The codepath to read from marks files in fast-import/export did not
  47   have to accept anything but 40-hex representation of the object
  48   name.  Further, fast-export did not need full in-core object
  49   representation to have parsed wen reading from them.  These
  50   codepaths have been optimized by taking advantage of these access
  51   patterns.
  52
  53 * Object lookup logic, when the object hashtable starts to become
  54   crowded, has been optimized.
  55
  56 * When TEST_OUTPUT_DIRECTORY setting is used, it was handled somewhat
  57   inconsistently between the test framework and t/Makefile, and logic
  58   to summarize the results looked at a wrong place.
  59
  60 * Many warnings from sparse source checker in compat/ area has been
  61   squelched.
  62
  63 * The code to reading and updating packed-refs file has been updated,
  64   correcting corner case bugs.
  65
  66
  67Also contains various documentation updates and code clean-ups.

  70Fixes since v1.8.3
  71------------------
  72
  73Unless otherwise noted, all the fixes since v1.8.3 in the maintenance
  74track are contained in this release (see release notes to them for
  75details).
  76
  77 * "git merge @{-1}~22" was rewritten to "git merge frotz@{1}~22"
  78   incorrectly when your previous branch was "frotz" (it should be
  79   rewritten to "git merge frotz~22" instead).
  80   (merge 84cf246 jc/strbuf-branchname-fix later to maint).
  81
  82 * "git diff -c -p" was not showing a deleted line from a hunk when
  83   another hunk immediately begins where the earlier one ends.
  84   (merge aac3857 mk/combine-diff-context-horizon-fix later to maint).
  85
  86 * "git log --ancestry-path A...B" did not work as expected, as it did
  87   not pay attention to the fact that the merge base between A and B
  88   was the bottom of the range being specified.
  89   (merge a765499 kb/ancestry-path-threedots later to maint).
  90
  91 * Mac OS X does not like to write(2) more than INT_MAX number of
  92   bytes; work it around by chopping write(2) into smaller pieces.
  93   (merge 6c642a8 fc/macos-x-clipped-write later to maint).
  94
  95 * Newer MacOS X encourages the programs to compile and link with
  96   their CommonCrypto, not with OpenSSL.
  97   (merge be4c828 da/darwin later to maint).
  98
  99 * "git clone foo/bar:baz" cannot be a request to clone from a remote
 100   over git-over-ssh specified in the scp style.  This case is now
 101   detected and clones from a local repository at "foo/bar:baz".
 102   (merge 6000334 nd/clone-local-with-colon later to maint).
 103
 104 * When $HOME is misconfigured to point at an unreadable directory, we
 105   used to complain and die. Loosen the check.
 106   (merge 4698c8f jn/config-ignore-inaccessible later to maint).
 107
 108 * "git subtree" (in contrib/) had one codepath with loose error
 109   checks to lose data at the remote side.
 110   (merge 3212d56 jk/subtree-do-not-push-if-split-fails later to maint).
 111
 112 * "git fetch" into a shallow repository from a repository that does
 113   not know about the shallow boundary commits (e.g. a different fork
 114   from the repository the current shallow repository was cloned from)
 115   did not work correctly.
 116   (merge 71d5f93 mh/fetch-into-shallow later to maint).
 117
 118 * "git checkout foo" DWIMs the intended "upstream" and turns it into
 119   "git checkout -t -b foo remotes/origin/foo". This codepath has been
 120   updated to correctly take existing remote definitions into account.
 121   (merge 229177a jh/checkout-auto-tracking later to maint).
