Git v2.4.5 Release Notes
========================

Fixes since v2.4.4
------------------

 * The setup code used to die when core.bare and core.worktree are set
   inconsistently, even for commands that do not need working tree.

 * There was a dead code that used to handle "git pull --tags" and
   show special-cased error message, which was made irrelevant when
   the semantics of the option changed back in Git 1.9 days.

 * "color.diff.plain" was a misnomer; give it 'color.diff.context' as
   a more logical synonym.

 * The configuration reader/writer uses mmap(2) interface to access
   the files; when we find a directory, it barfed with "Out of memory?".

 * Recent "git prune" traverses young unreachable objects to safekeep
   old objects in the reachability chain from them, which sometimes
   showed unnecessary error messages that are alarming.

 * "git rebase -i" fired post-rewrite hook when it shouldn't (namely,
   when it was told to stop sequencing with 'exec' insn).

Also contains typofixes, documentation updates and trivial code
clean-ups.
