RELEASE_NOTES

@@ -1,3 +1,129 @@
+1.4.5:
+------
+
+- Introduced 2 new variables in /etc/piler/piler.conf affecting piler-smtp
+
+  ; max message size in bytes
+  ; piler-smtp will reject any message that's bigger than this number
+  max_message_size=50000000
+
+  ; max memory in bytes piler-smtp uses for buffering messages
+  ; when this limit is exceeded, no new emails will be accepted
+  ; until the used memory for all in progress emails decreases
+  ; below this level
+  max_smtp_memory=500000000
+
+  Be sure to adjust these values to your environment!
+
+- Added read-only connection support for manticore
+  If using sphinx, add the following to config-site.php:
+  $config['SPHINX_HOSTNAME_READONLY'] = '127.0.0.1:9306';
+
+- pilerimport supports Zimbra IMAP impersonation
+
+  Generate the following base64 encoded string:
+  (Be sure to use the actual usernames and password):
+
+  pw="$( printf '%s\0%s\0%s' 'username' 'zimbra_admin_username' 'zimbra_admin_password' | base64 )"
+
+  Then specify -u ZIMBRA -p "$pw" for pilerimport, eg.
+
+  pilerimport -i imap.server -u ZIMBRA -p "$pw" ...
+
+  Note that "ZIMBRA" is a special username, it indicates for pilerimport
+  to actually use the imap impersonation for Zimbra.
+
+

+  Be sure to run util/db-upgrade.sql on the mysql piler database

+  - TLSv1.2 (default)
+  - TLSv1.3

+  of protocol://hostname:port, eg. ldaps://ldap.example.com:636
+
+1.3.10:
+-------
+
+- Added security header feature
+- Introduced the smtp acl list, and obsoleted the tcp_wrappers check
