+==========================
+
+Fixes since v1.6.6.1
+--------------------
+
+ * recursive merge didn't correctly diagnose its own programming errors,
+   and instead caused the caller to segfault.
+
+ * The new "smart http" aware clients probed the web servers to see if
+   they support smart http, but did not fall back to dumb http transport
+   correctly with some servers.
+
+ * Time based reflog syntax e.g. "@{yesterday}" didn't diagnose a misspelled
+   time specification and instead assumed "@{now}".
+
+ * "git archive HEAD -- no-such-directory" produced an empty archive
+   without complaining.
+
+ * "git blame -L start,end -- file" misbehaved when given a start that is
+   larger than the number of lines in the file.
+
+ * "git checkout -m" didn't correctly call custom merge backend supplied
+   by the end user.
+
+ * "git config -f <file>" misbehaved when run from a subdirectory.
+
+ * "git cvsserver" didn't like having regex metacharacters (e.g. '+') in
+   CVSROOT environment.
+
+ * "git fast-import" did not correctly handle large blobs that may
+   bust the pack size limit.
+
+ * "git gui" is supposed to work even when launched from inside a .git
+   directory.
+
+ * "git gui" misbehaved when applying a hunk that ends with deletion.
+
+ * "git imap-send" did not honor imap.preformattedHTML as documented.
+
+ * "git log" family incorrectly showed the commit notes unconditionally by
+   mistake, which was especially irritating when running "git log --oneline".
+
+ * "git status" shouldn't require an write access to the repository.
+
+Other minor documentation updates are included.
