+Git v1.6.5.6 Release Notes
+==========================
+
+Fixes since v1.6.5.5
+--------------------
+
+ * "git add -p" had a regression since v1.6.5.3 that broke deletion of
+   non-empty files.
+
+ * "git archive -o o.zip -- Makefile" produced an archive in o.zip
+   but in POSIX tar format.
+
+ * Error message given to "git pull --rebase" when the user didn't give
+   enough clue as to what branch to integrate with still talked about
+   "merging with" the branch.
+
+ * Error messages given by "git merge" when the merge resulted in a
+   fast-forward still were in plumbing lingo, even though in v1.6.5
+   we reworded messages in other cases.
+
+ * The post-upload-hook run by upload-pack in response to "git fetch" has
+   been removed, due to security concerns (the hook first appeared in
+   1.6.5).

-post-upload-pack
-----------------
-
-After upload-pack successfully finishes its operation, this hook is called
-for logging purposes.
-
-The hook is passed various pieces of information, one per line, from its
-standard input.  Currently the following items can be fed to the hook, but
-more types of information may be added in the future:
-
-want SHA-1::
-    40-byte hexadecimal object name the client asked to include in the
-    resulting pack.  Can occur one or more times in the input.
-
-have SHA-1::
-    40-byte hexadecimal object name the client asked to exclude from
-    the resulting pack, claiming to have them already.  Can occur zero
-    or more times in the input.
-
-time float::
-    Number of seconds spent for creating the packfile.
-
-size decimal::
-    Size of the resulting packfile in bytes.
-
-kind string:
-    Either "clone" (when the client did not give us any "have", and asked
-    for all our refs with "want"), or "fetch" (otherwise).
