   1 GIT v1.6.5 Release Notes
   2 ========================
   3
   4 In git 1.7.0, which was planned to be the release after 1.6.5, "git
   5 push" into a branch that is currently checked out will be refused by
   6 default.
   7
   8 You can choose what should happen upon such a push by setting the
   9 configuration variable receive.denyCurrentBranch in the receiving
  10 repository.
  11
  12 Also, "git push $there :$killed" to delete the branch $killed in a remote
  13 repository $there, when $killed branch is the current branch pointed at by
  14 its HEAD, will be refused by default.
  15
  16 You can choose what should happen upon such a push by setting the
  17 configuration variable receive.denyDeleteCurrent in the receiving
  18 repository.
  19
  20 To ease the transition plan, the receiving repository of such a
  21 push running this release will issue a big warning when the
  22 configuration variable is missing.  Please refer to:

  30 Updates since v1.6.4
  31 --------------------
  32
  33 (subsystems)
  34
  35  * various updates to gitk, git-svn and gitweb.
  36
  37 (portability)
  38
  39  * more improvements on mingw port.
  40
  41  * mingw will also give FRSX as the default value for the LESS
  42    environment variable when the user does not have one.
  43
  44  * initial support to compile git on Windows with MSVC.
  45
  46 (performance)
  47
  48  * On major platforms, the system can be compiled to use with Linus's
  49    block-sha1 implementation of the SHA-1 hash algorithm, which
  50    outperforms the default fallback implementation we borrowed from
  51    Mozilla.
  52
  53  * Unnecessary inefficiency in deepening of a shallow repository has
  54    been removed.
  55
  56  * "git clone" does not grab objects that it does not need (i.e.
  57    referenced only from refs outside refs/heads and refs/tags
  58    hierarchy) anymore.
  59
  60  * The "git" main binary used to link with libcurl, which then dragged
  61    in a large number of external libraries.  When using basic plumbing
  62    commands in scripts, this unnecessarily slowed things down.  We now
  63    implement http/https/ftp transfer as a separate executable as we
  64    used to.
  65
  66  * "git clone" run locally hardlinks or copies the files in .git/ to
  67    newly created repository.  It used to give new mtime to copied files,
  68    but this delayed garbage collection to trigger unnecessarily in the
  69    cloned repository.  We now preserve mtime for these files to avoid
  70    this issue.
  71
  72 (usability, bells and whistles)
  73
  74  * Human writable date format to various options, e.g. --since=yesterday,
  75    master@{2000.09.17}, are taught to infer some omitted input properly.
  76
  77  * A few programs gave verbose "advice" messages to help uninitiated
  78    people when issuing error messages.  An infrastructure to allow
  79    users to squelch them has been introduced, and a few such messages
  80    can be silenced now.
  81
  82  * refs/replace/ hierarchy is designed to be usable as a replacement
  83    of the "grafts" mechanism, with the added advantage that it can be
  84    transferred across repositories.
  85
  86  * "git am" learned to optionally ignore whitespace differences.
  87
  88  * "git am" handles input e-mail files that has CRLF line endings sensibly.
  89
  90  * "git am" learned "--scissors" option to allow you to discard early part
  91    of an incoming e-mail.
  92
  93  * "git archive -o output.zip" works without being told what format to
  94    use with an explicit "--format=zip".option.
  95
  96  * "git checkout", "git reset" and "git stash" learned to pick and
  97    choose to use selected changes you made, similar to "git add -p".
  98
  99  * "git clone" learned a "-b" option to pick a HEAD to check out
 100    different from the remote's default branch.
 101
 102  * "git clone" learned --recursive option.
 103
 104  * "git clone" from a local repository on a different filesystem used to
 105    copy individual object files without preserving the old timestamp, giving
 106    them extra lifetime in the new repository until they gc'ed.
 107
 108  * "git commit --dry-run $args" is a new recommended way to ask "what would
 109    happen if I try to commit with these arguments."
 110
 111  * "git commit --dry-run" and "git status" shows conflicted paths in a
 112    separate section to make them easier to spot during a merge.
 113
 114  * "git cvsimport" now supports password-protected pserver access even
 115    when the password is not taken from ~/.cvspass file.
 116
 117  * "git fast-export" learned --no-data option that can be useful when
 118    reordering commits and trees without touching the contents of
 119    blobs.
 120
 121  * "git fast-import" has a pair of new front-end in contrib/ area.
 122
 123  * "git init" learned to mkdir/chdir into a directory when given an
 124    extra argument (i.e. "git init this").
 125
 126  * "git instaweb" optionally can use mongoose as the web server.
 127
 128  * "git log --decorate" can optionally be told with --decorate=full to
 129    give the reference name in full.
 130
 131  * "git merge" issued an unnecessarily scary message when it detected
 132    that the merge may have to touch the path that the user has local
 133    uncommitted changes to. The message has been reworded to make it
 134    clear that the command aborted, without doing any harm.
 135
 136  * "git push" can be told to be --quiet.
 137
 138  * "git push" pays attention to url.$base.pushInsteadOf and uses a URL
 139    that is derived from the URL used for fetching.
 140
 141  * informational output from "git reset" that lists the locally modified
 142    paths is made consistent with that of "git checkout $another_branch".
 143
 144  * "git submodule" learned to give submodule name to scripts run with
 145    "foreach" subcommand.
 146
 147  * various subcommands to "git submodule" learned --recursive option.
 148
 149  * "git submodule summary" learned --files option to compare the work
 150    tree vs the commit bound at submodule path, instead of comparing
 151    the index.
 152
 153  * "git upload-pack", which is the server side support for "git clone" and
 154    "git fetch", can call a new post-upload-pack hook for statistics purposes.
 155
 156 (developers)
 157
 158  * With GIT_TEST_OPTS="--root=/p/a/t/h", tests can be run outside the
 159    source directory; using tmpfs may give faster turnaround.
 160
 161  * With NO_PERL_MAKEMAKER set, DESTDIR= is now honoured, so you can
 162    build for one location, and install into another location to tar it
 163    up.
