role disabled by configuration, the tlsproxy daemon
dereferenced a null pointer while handling a tlsproxy client
request. Reported by John Doe. File: tlsproxy/tlsproxy.c.

+
+ Bugfix (defect introduced: Postfix 3.0, date 20140731): the
+ smtpd 'disconnect' command counts did not count malformed
+ commands with "bad syntax" and "bad UTF-8 syntax" errors.
+ File: smtpd/smtpd.c.
+
+20250819
+
+ Bugfix: the 20250717 workaround broke DBM library support
+ which is still needed on Solaris. File: util/dict_dbm.c.
+
+20250823
+
+ Bugfix (defect introduced: Postfix 3.9, date 20230517):
+ posttls-finger logged a zero port number. Viktor Dukhovni.
+ File: posttls-finger/posttls-finger.c.
+
+20250829
+
+ Postfix 3.11 forward compatibility: allow a partial 'size'
+ record in maildrop queue files created with Postfix 3.11
+ or later, instead of logging an ugly warning. Files:
+ showq/showq.c, postcat/postcat.c.
+
+20250911
+
+ Bugfix (defect introduced: Postfix 3.0): the Postfix SMTP
+ client's connection reuse logic did not distinguish between
+ sessions that require SMTPUTF8 support, and sessions that
+ do not. The solution is to store sessions with different
+ SMTPUTF8 requirements under distinct connection cache storage
+ keys, and to preserve the availability of SMTPUTF8 support
+ in the connection cache, so that a reused connection will
+ be stored under the same keys as it was looked up with.
+ Finally, do not cache a connection when SMTPUTF8 is
+ required but the server does not support that feature.
+ Files: smtp/smtp.h, smtp/smtp_key.c, smtp/smtp_proto.c.
+
+20250919
+
+ Bugfix (defect introduced: Postfix 3.8, date 20220128): the
+ 'postconf -e' output order for new main.cf entries was no
+ longer deterministic. Problem reported by Oleksandr Natalenko,
+ diagnosis by Eray Aslan. File: postconf/postconf_edit.c.
+
+ Add missing meta_directory and shlib_directory settings to
+ the stock main.cf file. Problem diagnosed by Eray Aslan.
+ File: conf/main.cf.
+
+20251021
+
+ Cleanup: the change at 20250717 could result in warnings
+ with "database X is older than source file Y". Files:
+ util/dict.c, util/dict_db.c, util/dict_dbm.c, util/dict_lmdb.c,
+ util/dict_sdbm.c.
