   1 Git v1.7.11 Release Notes
   2 =========================
   3
   4 Updates since v1.7.10
   5 ---------------------
   6
   7 UI, Workflows & Features
   8
   9  * A new mode for push, "simple", which is a cross between "current"
  10    and "upstream", has been introduced. "git push" without any refspec
  11    will push the current branch out to the same name at the remote
  12    repository only when it is set to track the branch with the same
  13    name over there.  The plan is to make this mode the new default
  14    value when push.default is not configured.
  15
  16  * A couple of commands learned the "--column" option to produce
  17    columnar output.
  18
  19  * A third-party tool "git subtree" is distributed in contrib/
  20
  21  * A remote helper that acts as a proxy and caches ssl session for the
  22    https:// transport is added to the contrib/ area.
  23
  24  * Error messages given when @{u} is used for a branch without its
  25    upstream configured have been clarified.
  26
  27  * Even with the "-q"uiet option, "checkout" used to report setting up
  28    tracking.  Also "branch" learned the "-q"uiet option to squelch
  29    informational message.
  30
  31  * Your build platform may support hardlinks but you may prefer not to
  32    use them, e.g. when installing to DESTDIR to make a tarball and
  33    untarring on a filesystem that has poor support for hardlinks.
  34    There is a Makefile option NO_INSTALL_HARDLINKS for you.
  35
  36  * The smart-http backend used to always override GIT_COMMITTER_*
  37    variables with REMOTE_USER and REMOTE_ADDR, but these variables are
  38    now preserved when set.
  39
  40  * "git am" learned the "--include" option, which is an opposite of
  41    existing the "--exclude" option.
  42
  43  * When "git am -3" needs to fall back to an application of the patch
  44    to a synthesized preimage followed by a 3-way merge, the paths that
  45    needed such treatment are now reported to the end user, so that the
  46    result in them can be eyeballed with extra care.
  47
  48  * The output from "diff/log --stat" used to always allocate 4 columns
  49    to show the number of modified lines, but not anymore.
  50
  51  * "git difftool" learned the "--dir-diff" option to spawn external
  52    diff tools that can compare two directory hierarchies at a time
  53    after populating two temporary directories, instead of running an
  54    instance of the external tool once per a file pair.
  55
  56  * The "fmt-merge-msg" command learned to list the primary contributors
  57    involved in the side topic you are merging in a comment in the merge
  58    commit template.
  59
  60  * "git rebase" learned to optionally keep commits that do not
  61    introduce any change in the original history.
  62
  63  * "git push --recurse-submodules" learned to optionally look into the
  64    histories of submodules bound to the superproject and push them
  65    out.
  66
  67  * A 'snapshot' request to "gitweb" honors If-Modified-Since: header,
  68    based on the commit date.
  69
  70  * "gitweb" learned to highlight the patch it outputs even more.
  71
  72 Foreign Interface
  73
  74  * "git svn" used to die with unwanted SIGPIPE when talking with an HTTP
  75    server that uses keep-alive.
  76
  77  * "git svn" learned to use platform specific authentication
  78    providers, e.g. gnome-keyring, kwallet, etc.
  79
  80  * "git p4" has been moved out of the contrib/ area and has seen more
  81    work on importing labels as tags from (and exporting tags as labels
  82    to) p4.
  83
  84 Performance and Internal Implementation (please report possible regressions)
  85
  86  * Bash completion script (in contrib/) have been cleaned up to make
  87    future work on it simpler.
  88
  89  * An experimental "version 4" format of the index file has been
  90    introduced to reduce on-disk footprint and I/O overhead.
  91
  92  * "git archive" learned to produce its output without reading the
  93    blob object it writes out in memory in its entirety.
  94
  95  * "git index-pack" that runs when fetching or pushing objects to
  96    complete the packfile on the receiving end learned to use multiple
  97    threads to do its job when available.
  98
  99  * The code to compute hash values for lines used by the internal diff
 100    engine was optimized on little-endian machines, using the same
 101    trick the kernel folks came up with.
 102
 103  * "git apply" had some memory leaks plugged.
 104
 105  * Setting up a revision traversal with many starting points was
 106    inefficient as these were placed in a date-order priority queue
 107    one-by-one.  Now they are collected in the queue unordered first,
 108    and sorted immediately before getting used.
 109
 110  * More lower-level commands learned to use the streaming API to read
 111    from the object store without keeping everything in core.
 112
 113  * The weighting parameters to suggestion command name typo have been
 114    tweaked, so that "git tags" will suggest "tag?" and not "stage?".
 115
 116  * Because "sh" on the user's PATH may be utterly broken on some
 117    systems, run-command API now uses SHELL_PATH, not /bin/sh, when
 118    spawning an external command (not applicable to Windows port).
 119
 120  * The API to iterate over the refs/ hierarchy has been tweaked to
 121    allow walking only a subset of it more efficiently.
 122
 123 Also contains minor documentation updates and code clean-ups.

 126 Fixes since v1.7.10
 127 -------------------
 128
 129 Unless otherwise noted, all the fixes since v1.7.10 in the maintenance
 130 releases are contained in this release (see release notes to them for
 131 details).
 132
 133  * "git submodule init" used to report "registered for path ..."
 134    even for submodules that were registered earlier.
 135    (cherry-pick c1c259e jl/submodule-report-new-path-once later to maint).
 136
 137  * "git diff --stat" used to fully count a binary file with modified
 138    execution bits whose contents is unmodified, which was not quite
 139    right.
