-+GIT v1.5.2.4 Release Notes
-+==========================
-+
-+Fixes since v1.5.2.3
-+--------------------
-+
-+ * Bugfixes
-+
-+   - "git-gui" bugfixes, including a handful fixes to run it
-+     better on Cygwin/MSYS.
-+
-+   - "git checkout" failed to switch back and forth between
-+     branches, one of which has "frotz -> xyzzy" symlink and
-+     file "xyzzy/filfre", while the other one has a file
-+     "frotz/filfre".
-+
-+   - "git prune" used to segfault upon seeing a commit that is
-+     referred to by a tree object (aka "subproject").
-+
-+   - "git diff --name-status --no-index" mishandled an added file.
-+
-+   - "git apply --reverse --whitespace=warn" still complained
-+     about whitespaces that a forward application would have
-+     introduced.
-+
-+ * Documentation Fixes and Updates
-+
-+   - A handful documentation updates.
