 +Git v1.7.10 Release Notes
 +=========================
 +
 +Updates since v1.7.9
 +--------------------
 +
 +UI, Workflows & Features
 +
 + * Improved handling of views, labels and branches in git-p4 (in contrib).
 +
 + * "git-p4" (in contrib) suffered from unnecessary merge conflicts when
 +   p4 expanded the embedded $RCS$-like keywords; it can be now told to
 +   unexpand them.
 +
 + * Some "git-svn" updates.
 +
 + * "vcs-svn"/"svn-fe" learned to read dumps with svn-deltas and
 +   support incremental imports.
 +
 + * The configuration mechanism learned an "include" facility; an
 +   assignment to the include.path pseudo-variable causes the named
 +   file to be included in-place when Git looks up configuration
 +   variables.
 +
 + * "git am" learned to pass "-b" option to underlying "git mailinfo", so
 +   that bracketed string other than "PATCH" at the beginning can be kept.
 +
 + * "git clone" learned "--single-branch" option to limit cloning to a
 +   single branch (surprise!).
 +
 + * "git clone" learned to detach the HEAD in the resulting repository
 +   when the source repository's HEAD does not point to a branch.
 +
 + * When showing a patch while ignoring whitespace changes, the context
 +   lines are taken from the postimage, in order to make it easier to
 +   view the output.
 +
 + * "diff-highlight" filter (in contrib/) was updated to produce more
 +   aesthetically pleasing output.
 +
 + * "git tag --list" can be given "--points-at <object>" to limit its
 +   output to those that point at the given object.
 +
 + * "git merge" in an interactive session learned to spawn the editor
 +   by default to let the user edit the auto-generated merge message,
 +   to encourage people to explain their merges better. Legacy scripts
 +   can export MERGE_AUTOEDIT=no to retain the historical behaviour.
 +   Both "git merge" and "git pull" can be given --no-edit from the
 +   command line to accept the auto-generated merge message.
 +
 + * "gitweb" allows intermediate entries in the directory hierarchy
 +   that leads to a projects to be clicked, which in turn shows the
 +   list of projects inside that directory.
 +
 +Performance
 +
 + * During "git upload-pack" in respose to "git fetch", unnecessary calls
 +   to parse_object() have been eliminated, to help performance in
 +   repositories with excessive number of refs.
 +
 +Internal Implementation (please report possible regressions)
 +
 + * Recursive call chains in "git index-pack" to deal with long delta
 +   chains have been flattened, to reduce the stack footprint.
 +
 + * Use of add_extra_ref() API is now gone, to make it possible to
 +   cleanly restructure the overall refs API.
 +
 + * The command line parser of "git pack-objects" now uses parse-options
 +   API.
 +
 + * The test suite supports the new "test_pause" helper function.
 +
 + * Parallel to the test suite, there is a beginning of performance
 +   benchmarking framework.
 +
 + * t/Makefile is adjusted to prevent newer versions of GNU make from
 +   running tests in seemingly random order.
 +
 +Also contains minor documentation updates and code clean-ups.
 +
 +
 +Fixes since v1.7.9
 +------------------
 +
 +Unless otherwise noted, all the fixes since v1.7.9 in the maintenance
 +releases are contained in this release (see release notes to them for
 +details).
 +
-  * The config.mak.autogen generated by optional autoconf support tried
-    to link the binary with -lintl even when libintl.h is missing from
-    the system.
-    (merge a8356d4 js/configure-libintl later to maint).
- 
-  * "git add --refresh <pathspec>" used to warn about unmerged paths
-    outside the given pathspec.
-    (merge 3d1f148 jc/add-refresh-unmerged later to maint).
- 
 + * "gitweb" used to drop warnings in the log file when "heads" view is
 +   accessed in a repository whose HEAD does not point at a valid
 +   branch.
