Git v2.2 Release Notes

======================

Updates since v2.1

------------------

UI, Workflows & Features

* "git config --edit --global" starts from a skeletal per-user

configuration file contents, instead of a total blank, when the

user does not already have any. This immediately reduces the

need for a later "Have you forgotten setting core.user?" and we

can add more to the template as we gain more experience.

Performance, Internal Implementation, etc.

* Looking up remotes configuration in a repository with very many

remotes defined has been optimized.

* There are cases where you lock and open to write a file, close it

to show the updated contents to external processes, and then have

to update the file again while still holding the lock, but the

lockfile API lacked support for such an access pattern.

* An in-core caching layer to let us avoid reading the same

configuration files number of times has been added.

* Various code paths have been cleaned up and simplified by using

"strbuf", "starts_with()", and "skip_prefix()" APIs more.

Also contains various documentation updates and code clean-ups.

Fixes since v2.1

----------------

* "git log --pretty/format=" with an empty format string did not

mean the more obvious "No output whatsoever" but "Use default

format", which was counterintuitive.

(merge b9c7d6e jk/pretty-empty-format later to maint).

* Implementations of "tar" that do not understand an extended pax

header would extract the contents of it in a regular file; make

sure the permission bits of this file follows the same tar.umask

configuration setting.

Unless otherwise noted, all the fixes since v2.1 in the maintenance

track are contained in this release (see the maintenance releases'

notes for details).
