   1GIT v1.6.0 Release Notes
   2========================

   5--------------------
   6
   7With the default Makefile settings, most of the programs are now
   8installed outside your $PATH, except for "git", "gitk", "git-gui" and
   9some server side programs that need to be accessible for technical
  10reasons.  Invoking a git subcommand as "git-xyzzy" from the command
  11line has been deprecated since early 2006 (and officially announced in
  121.5.4 release notes); use of them from your scripts after adding
  13output from "git --exec-path" to the $PATH is still supported in this
  14release, but users are again strongly encouraged to adjust their
  15scripts to use "git xyzzy" form, as we will stop installing
  16"git-xyzzy" hardlinks for built-in commands in later releases.
  17
  18An earlier change to page "git status" output was overwhelmingly unpopular
  19and has been reverted.
  20
  21Source changes needed for porting to MinGW environment are now all in the
  22main git.git codebase.
  23
  24By default, packfiles created with this version uses delta-base-offset
  25encoding introduced in v1.4.4.  Pack idx files are using version 2 that
  26allows larger packs and added robustness thanks to its CRC checking,
  27introduced in v1.5.2 and v1.4.4.5.  If you want to keep your repositories
  28backwards compatible past these versions, set repack.useDeltaBaseOffset
  29to false or pack.indexVersion to 1, respectively.
  30
  31GIT_CONFIG, which was only documented as affecting "git config", but
  32actually affected all git commands, now only affects "git config".
  33GIT_LOCAL_CONFIG, also only documented as affecting "git config" and
  34not different from GIT_CONFIG in a useful way, is removed.
  35
  36The ".dotest" temporary area "git am" and "git rebase" use is now moved
  37inside the $GIT_DIR, to avoid mistakes of adding it to the project by
  38accident.
  39
  40An ancient merge strategy "stupid" has been removed.
  41

  43Updates since v1.5.6
  44--------------------
  45
  46(subsystems)
  47
  48* git-p4 in contrib learned "allowSubmit" configuration to control on
  49  which branch to allow "submit" subcommand.
  50
  51* git-gui learned to stage changes per-line.
  52
  53(portability)
  54
  55* Changes for MinGW port have been merged, thanks to Johannes Sixt and
  56  gangs.
  57
  58* Sample hook scripts shipped in templates/ are now suffixed with
  59  *.sample.  We used to prevent them from triggering by default by
  60  relying on the fact that we install them as unexecutable, but on
  61  some filesystems this approach does not work.  Instead of running
  62  "chmod +x" on them, the users who want to activate these samples
  63  as-is can now rename them dropping *.sample suffix.
  64
  65* perl's in-place edit (-i) does not work well without backup files on Windows;
  66  some tests are rewritten to cope with this.
  67
  68(documentation)
  69
  70* Updated howto/update-hook-example
  71
  72* Got rid of usage of "git-foo" from the tutorial and made typography
  73  more consistent.
  74
  75* Disambiguating "--" between revs and paths is finally documented.
  76
  77(performance, robustness, sanity etc.)
  78
  79* index-pack used too much memory when dealing with a deep delta chain.
  80  This has been optimized.
  81
  82* reduced excessive inlining to shrink size of the "git" binary.
  83
  84* verify-pack checks the object CRC when using version 2 idx files.
  85
  86* When an object is corrupt in a pack, the object became unusable even
  87  when the same object is available in a loose form,  We now try harder to
  88  fall back to these redundant objects when able.  In particular, "git
  89  repack -a -f" can be used to fix such a corruption as long as necessary
  90  objects are available.
  91
  92* Performance of "git-blame -C -C" operation is vastly improved.
  93
  94* git-clone does not create refs in loose form anymore (it behaves as
  95  if you immediately ran git-pack-refs after cloning).  This will help
  96  repositories with insanely large number of refs.
  97
  98* core.fsyncobjectfiles configuration can be used to ensure that the loose
  99  objects created will be fsync'ed (this is only useful on filesystems
 100  that does not order data writes properly).
 101
 102* "git commit-tree" plumbing can make Octopus with more than 16 parents.
 103  "git commit" has been capable of this for quite some time.
 104
 105(usability, bells and whistles)
 106
 107* even more documentation pages are now accessible via "man" and "git help".
 108
 109* A new environment variable GIT_CEILING_DIRECTORIES can be used to stop
 110  the discovery process of the toplevel of working tree; this may be useful
 111  when you are working in a slow network disk and are outside any working tree,
 112  as bash-completion and "git help" may still need to run in these places.
 113
 114* By default, stash entries never expire.  Set reflogexpire in [gc
 115  "refs/stash"] to a reasonable value to get traditional auto-expiration
 116  behaviour back
 117
 118* Longstanding latency issue with bash completion script has been
 119  addressed.  This will need to be backmerged to 'maint' later.
 120
 121* pager.<cmd> configuration variable can be used to enable/disable the
 122  default paging behaviour per command.
 123
 124* "git-add -i" has a new action 'e/dit' to allow you edit the patch hunk
 125  manually.
 126
 127* git-am records the original tip of the branch in ORIG_HEAD before it
 128  starts applying patches.
 129
 130* git-apply can handle a patch that touches the same path more than once
 131  much better than before.
 132
 133* git-apply can be told not to trust the line counts recorded in the input
 134  patch but recount, with the new --recount option.
 135
 136* git-apply can be told to apply a patch to a path deeper than what the
 137  patch records with --directory option.
 138
 139* git-archive can be told to omit certain paths from its output using
 140  export-ignore attributes.
 141
 142* git-archive uses the zlib default compression level when creating
 143  zip archive.
 144
 145* With -v option, git-branch describes the remote tracking statistics
 146  similar to the way git-checkout reports by how many commits your branch
 147  is ahead/behind.
 148
 149* git-branch's --contains option used to always require a commit parameter
 150  to limit the branches with; it now defaults to list branches that
 151  contains HEAD if this parameter is omitted.
 152
 153* git-branch's --merged and --no-merged option used to always limit the
 154  branches relative to the HEAD, but they can now take an optional commit
 155  argument that is used in place of HEAD.
 156
 157* git-bundle can read the revision arguments from the standard input.
 158
 159* git-cherry-pick can replay a root commit now.
 160
 161* git-clone can clone from a remote whose URL would be rewritten by
 162  configuration stored in $HOME/.gitconfig now.
 163
 164* git-cvsserver learned to respond to "cvs co -c".
 165
 166* git-diff --check now checks leftover merge conflict markers.
 167
 168* When remote side used to have branch 'foo' and git-fetch finds that now
 169  it has branch 'foo/bar', it refuses to lose the existing remote tracking
 170  branch and its reflog.  The error message has been improved to suggest
 171  pruning the remote if the user wants to proceed and get the latest set
 172  of branches from the remote, including such 'foo/bar'.
 173
 174* fast-export learned to export and import marks file; this can be used to
 175  interface with fast-import incrementally.
 176
 177* fast-import and fast-export learned to export and import gitlinks.
 178
 179* git-rebase records the original tip of branch in ORIG_HEAD before it is
 180  rewound.
 181
 182* "git rerere" can be told to update the index with auto-reused resolution
 183  with rerere.autoupdate configuration variable.
 184
 185* git-rev-parse learned $commit^! and $commit^@ notations used in "log"
 186  family.  These notations are available in gitk as well, because the gitk
 187  command internally uses rev-parse to interpret its arguments.
 188
 189* git-rev-list learned --children option to show child commits it
 190  encountered during the traversal, instead of shoing parent commits.
 191
 192* git-send-mail can talk not just over SSL but over TLS now.
 193
 194* git-shortlog honors custom output format specified with "--pretty=format:".
 195
 196* "git-stash save" learned --keep-index option.  This lets you stash away the
 197  local changes and bring the changes staged in the index to your working
 198  tree for examination and testing.
 199
 200* git-stash also learned branch subcommand to create a new branch out of
 201  stashed changes.
 202
 203* git-status gives the remote tracking statistics similar to the way
 204  git-checkout reports by how many commits your branch is ahead/behind.
 205
 206* "git-svn dcommit" is now aware of auto-props setting the subversion user
 207  has.
 208
 209* You can tell "git status -u" to even more aggressively omit checking
 210  untracked files with --untracked-files=no.
 211
 212* Original SHA-1 value for "update-ref -d" is optional now.
 213
 214* Error codes from gitweb are made more descriptive where possible, rather
 215  than "403 forbidden" as we used to issue everywhere.
 216
 217(internal)
 218
 219* git-merge has been reimplemented in C.
 220
 221
 222Fixes since v1.5.6
 223------------------
 224
 225All of the fixes in v1.5.6 maintenance series are included in
 226this release, unless otherwise noted.
 227
 228* git-clone ignored its -u option; the fix needs to be backported to
 229  'maint';
 230
 231* git-mv used to lose the distinction between changes that are staged
 232  and that are only in the working tree, by staging both in the index
 233  after moving such a path.
