 +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).
 +
 + * Updated command line arguments completion script for zsh (in contrib).
 +
 + * "vcs-svn"/"svn-fe" learned to read dumps with svn-deltas and
 +   support incremental imports.
 +
 + * "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.
 +
 + * The commands in the "git diff" family and "git apply --stat" that
 +   count the number of files changed and the number of lines
 +   inserted/deleted have been updated to match the output from
 +   "diffstat".  This also opens the door to i18n this line.
 +
 + * 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.
 +
 + * "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.
 +
 + * "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
 +
 + * 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 slowly getting removed, to make it
 +   possible to cleanly restructure the overall refs API.
 +
 + * The test suite supports the new "test_pause" helper function.
 +
 + * 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).
 +
-  * Many small corner case bugs on "git tag -n" was corrected.
-    (merge 31fd8d7 jk/maint-tag-show-fixes later to maint).
- 
 + * The error message emitted when we see an empty loose object was
 +   not phrased correctly.
 +   (merge 33e42de mm/empty-loose-error-message later to maint).
 +
 + * "git commit" refused to create a commit when entries added with
 +   "add -N" remained in the index, without telling Git what their content
 +   in the next commit should be. We should have created the commit without
 +   these paths.
 +   (merge 3f6d56d jc/maint-commit-ignore-i-t-a later to maint).
 +
 + * Search box in "gitweb" did not accept non-ASCII characters correctly.
 +   (merge 84d9e2d jn/gitweb-search-utf-8 later to maint).
 +
 + * The code to ask for password did not fall back to the terminal
 +   input when GIT_ASKPASS is set but does not work (e.g. lack of X
 +   with GUI askpass helper).
 +   (merge 84d7273 jk/prompt-fallback-to-tty later to maint).
 +
 + * map_user() was not rewriting its output correctly, which resulted
 +   in the user visible symptom that "git blame -e" sometimes showed
 +   excess '>' at the end of email addresses.
 +   (merge f026358 jc/maint-mailmap-output later to maint).
 +
 + * "checkout -b" did not allow switching out of an unborn branch.
 +   (merge abe1998 jc/checkout-out-of-unborn later to maint).
