Git 2.10 Release Notes
======================
Backward compatibility notes
----------------------------
Updates since v2.9
------------------
UI, Workflows & Features
* "git pull --rebase --verify-signature" learned to warn the user
that "--verify-signature" is a no-op when rebasing.
* An upstream project can make a recommendation to shallowly clone
some submodules in the .gitmodules file it ships.
* "git worktree add" learned that '-' can be used as a short-hand for
"@{-1}", the previous branch.
* Update the funcname definition to support css files.
* The completion script (in contrib/) learned to complete "git
status" options.
* Messages that are generated by auto gc during "git push" on the
receiving end are now passed back to the sending end in such a way
that they are shown with "remote: " prefix to avoid confusing the
users.
Performance, Internal Implementation, Development Support etc.
* "git fast-import" learned the same performance trick to avoid
creating too small a packfile as "git fetch" and "git push" have,
using *.unpackLimit configuration.
* When "git daemon" is run without --[init-]timeout specified, a
connection from a client that silently goes offline can hang around
for a long time, wasting resources. The socket-level KEEPALIVE has
been enabled to allow the OS to notice such failed connections.
(merge a43b68a ew/daemon-socket-keepalive later to maint).
* "git upload-pack" command has been updated to use the parse-options
API.
* The "git apply" standalone program is being libified; this is the
first step to move many state variables into a structure that can
be explicitly (re)initialized to make the machinery callable more
than once.
Also contains various documentation updates and code clean-ups.
Fixes since v2.9
----------------
Unless otherwise noted, all the fixes since v2.8 in the maintenance
track are contained in this release (see the maintenance releases'
notes for details).
* The commands in `git log` family take %C(auto) in a custom format
string. This unconditionally turned the color on, ignoring
--no-color or with --color=auto when the output is not connected to
a tty; this was corrected to make the format truly behave as
"auto".
(merge b15a3e0 et/pretty-format-c-auto later to maint).
* "git rev-list --count" whose walk-length is limited with "-n"
option did not work well with the counting optimized to look at the
bitmap index.
(merge fb85db8 jk/rev-list-count-with-bitmap later to maint).
* "git show -W" (extend hunks to cover the entire function, delimited
by lines that match the "funcname" pattern) used to show the entire
file when a change added an entire function at the end of the file,
which has been fixed.
(merge 6f8d9bc rs/xdiff-hunk-with-func-line later to maint).
* The documentation set has been updated so that literal commands,
configuration variables and environment variables are consistently
typeset in fixed-width font and bold in manpages.
(merge ae9f631 tr/doc-tt later to maint).
* "git svn propset" subcommand that was added in 2.3 days is
documented now.
(merge 19a7f24 ap/git-svn-propset-doc later to maint).
* The documentation tries to consistently spell "GPG"; when
referring to the specific program name, "gpg" is used.
(merge bc91316 dn/gpg-doc later to maint).
* "git reflog" stopped upon seeing an entry that denotes a branch
creation event (aka "unborn"), which made it appear as if the
reflog was truncated.
(merge 71abeb7 sg/reflog-past-root later to maint).
* The git-prompt scriptlet (in contrib/) was not friendly with those
who uses "set -u", which has been fixed.
(merge 34d8f5a vs/prompt-avoid-unset-variable later to maint).
* compat/regex code did not cleanly compile.
(merge bd8f005 rj/compat-regex-size-max-fix later to maint).
* A codepath that used alloca(3) to place an unbounded amount of data
on the stack has been updated to avoid doing so.
(merge b8ba412 jk/avoid-unbounded-alloca later to maint).
* "git update-index --add --chmod=+x file" may be usable as an escape
hatch, but not a friendly thing to force for people who do need to
use it regularly. "git add --chmod=+x file" can be used instead.
(merge 4e55ed3 et/add-chmod-x later to maint).
* Build improvements for gnome-keyring (in contrib/)
(merge 3cddb00 nb/gnome-keyring-build later to maint).
* "git status" used to say "working directory" when it meant "working
tree".
(merge 2a0e6cd lv/status-say-working-tree-not-directory later to maint).
* Comments about misbehaving FreeBSD shells have been clarified with
the version number (9.x and before are broken, newer ones are OK).
(merge 9b35cad em/newer-freebsd-shells-are-fine-with-returns later to maint).
* "git cherry-pick A" worked on an unborn branch, but "git
cherry-pick A..B" didn't.
(merge 0f974e2 mg/cherry-pick-multi-on-unborn later to maint).
* Other minor clean-ups and documentation updates
(merge 3a39f61 pc/occurred later to maint).
(merge 9e70233 jk/fetch-prune-doc later to maint).
(merge ed008d7 pb/strbuf-read-file-doc later to maint).
(merge 31da121 jc/deref-tag later to maint).
