+GIT v1.5.1 Release Notes
+========================
+
+Updates since v1.5.0
+--------------------
+
+* Deprecated commands and options.
+
+  - git-diff-stages and git-resolve have been removed.
+
+* New commands and options.
+
+  - "git log" and friends take --reverse.  This makes output
+    that typically goes reverse order in chronological order.
+    "git shortlog" usually lists commits in chronological order,
+    but with "--reverse", they are shown in reverse
+    chronological order.
+
+  - "git diff" learned --ignore-space-at-eol.  This is a weaker
+    form of --ignore-space-change.
+
+  - "git name-rev" learned --refs=<pattern>, to limit the tags
+    used for naming the given revisions only to the ones
+    matching the given pattern.
+
+* Updated behaviour of existing commands.
+
+  - "git diff" outputs a trailing HT when pathnames have embedded
+    SP on +++/--- header lines, in order to help "GNU patch" to
+    parse its output.  "git apply" was already updated to accept
+    this modified output format since ce74618d (Sep 22, 2006).
+
+* Hooks
+
+  - The sample update hook to show how to send out notification
+    e-mail was updated to show only new commits that appeared in
+    the repository.  Earlier, it showed new commits that appeared
+    on the branch.
