   - git-blame on a very long working tree path had buffer
     overrun problem.
 
+  - git-apply did not like to be fed two patches in a row that created
+    and then modified the same file.
+
+  - git-svn was confused when a non-project was stored directly under
+    trunk/, branches/ and tags/.
+
+  - git-svn wants the Error.pm module that was at least as new
+    as what we ship as part of git; install ours in our private
+    installation location if the one on the system is older.
+
+  - An earlier update to command line integer parameter parser was

 * Documentation updates
 
   - Various documentation updates from J. Bruce Fields, Frank
     Lichtenheld, Alex Riesen and others.  Andrew Ruder started a
     war on undocumented options.

+GIT v1.5.1.3 Release Notes (draft)
+==========================
+
+Fixes since v1.5.1.2
+--------------------
+
+* Bugfixes
+
+  - git-add tried to optimize by finding common leading
+    directories across its arguments but botched, causing very
+    confused behaviour.
+
+  - unofficial rpm.spec file shipped with git was letting
+    ETC_GITCONFIG set to /usr/etc/gitconfig.  Tweak the official
+    Makefile to make it harder for distro people to make the
+    same mistake, by setting the variable to /etc/gitconfig if
+    prefix is set to /usr.
+
+  - git-svn inconsistently stripped away username from the URL
+    only when svnsync_props was in use.
+
+  - git-send-email was not quoting recipient names that have
+    period '.' in them.  Also it did not allow overriding
+    envelope sender, which made it impossible to send patches to
+    certain subscriber-only lists.
+
+  - built-in write_tree() routine had a sequence that renamed a
+    file that is still open, which some systems did not like.
+
+  - when memory is very tight, sliding mmap code to read
+    packfiles incorrectly closed the fd that was still being
+    used to read the pack.
