Hello!

It is my pleasure to announce the *3.6.5* and *3.4.18* minor releases,
which include over 60 distinct fixes and improvements since
the previous minor releases.  This also marks the End-of-Life for
the *3.4* branch, according to the release policy 
<https://www.opensips.org/Development/Development>.

To name some improved areas: TLS handling, TCP/core stability,
Push Notification support, registrar and mid_registrar behavior, RTP and
media handling, B2B logic/entities, AAA Diameter, JSON-RPC, RabbitMQ
events, database and cache backends, plus several build and packaging
updates around Debian 13, Python, PCRE2/PCRE3, libcurl/OpenSSL, RedHat
and wolfSSL.

Some notable fixes include TLS client certificate handling and OpenSSL
per-thread cleanup, TCP file descriptor and Content-Length safety fixes,
MySQL prepared statement recovery, SQLite/sql_cacher interaction fixes,
Redis/Cassandra/Memcached error handling fixes, rtpengine/rtp_relay/Janus
stability fixes, and registrar handling of Re-REGISTERs with equal CSeq.

Do make sure to roll out an update as soon as possible -- it is highly
recommended.
