-TODO: gcf2, detached indices, JMAP, ...
+Another big release focused on multi-inbox search and scalability.
+
+* general changes
+
+  config file parsing is 2x faster with 50K inboxes
+
+* read-only public-inbox-daemon (-httpd, -nntpd, -imapd):
+
+  libgit2 may be used via Inline::C to avoid hitting system pipe
+  and process limits.  See public-inbox-tuning(7) manpage
+  for more details.
+
+* public-inbox-extindex
+
+  A new Xapian + SQLite index able to search across several inboxes.
+  This may be configured to replace per-inbox Xapian DBs,
+  (but not per-inbox SQLite indices) and speed up manifest.js.gz
+  generation.
+
+  See public-inbox-extindex-format(5) and
+  public-inbox-extindex(1) manpages for more details.
+
+* public-inbox-nntpd
+
+  - startup is 6x faster with 50K inboxes if using -extindex
+
+* PublicInbox::WWW
+
+  - mboxrd search results are returned in reverse Xapian docid order,
+    so more recent results are more likely to show up first
+
+  - d: and dt: search prefixes allow "approxidate" formats supported
+    by "git log --since="
+
+  - manifest.js.gz generation is ~25x faster with -extindex
+
+* lei - local email interface
+
+  An experimental, subject-to-change, likely-to-eat-your-mail tool for
+  personal mail as well as interacting with public-inboxes on the local
+  filesystem or over HTTP(S).  See lei(1), lei-overview(7), and other
+  lei-* manpages for details.
+
+* public-inbox-watch
+
+  - IMAP and NNTP code shared with lei, fixing an off-by-one error
+    in IMAP synchronization for single-message IMAP folders.
+
+  - \Deleted and \Draft messages ignored for IMAP, as they are for
+    Maildir.
+
+  - IMAP and NNTP connection establishment (including git-credential
+    prompts) ordering is now tied to config file order.
 
 Compatibility:
 
 * Rollbacks all the way to public-inbox 1.2.0 remain supported
 
+Internal changes
+
+* public-inbox-index switched to new internal IPC code shared
+  with lei
+
