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.

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.

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).

* Other minor clean-ups and documentation updates
