 Notmuch 0.29 (UNRELEASED)
 =========================
 
+General
+-------
+
+Add "body:" field to allow searching for terms that occur only in the
+message body. Users will need to reindex their mail to take advantage
+of this feature.
+
+Add support for indexing user specified headers (e.g. List-Id). See
+notmuch-config(1) for details. This requires reindexing after changing
+the set of headers to be indexed.
+
+Fix bug for searching in some headers for Xapian keywords in quoted
+strings.
+
+Add support for gzip compressed mail messages (/not/ multi-message
+mboxes); e.g. `gzip -9 $MAIL/archive/giant-message && notmuch new`
+should work. Note that maildir flag syncing for gzipped messages is
+currently untested.
+
 Command Line Interface
 ----------------------
 
 `notmuch show` now supports --body=false and --include-html with
 --format=text
