Greetings,

I have just released fetchmail 6.4.0-beta2, and can be
downloaded from
<https://sourceforge.net/projects/fetchmail/files/branch_6.4/>.

Important changes:
- SSL code reworked a bit with support for newer TLS protocols, more
options for --sslproto, and some decoupling of the SSL protocol version
versus if a service is SSL-wrapped (--ssl option) or uses STARTTLS
(default).
- SSLv2 dropped, SSLv3 deprecated and not negotiated by default.
- Compatibility improved with newer OpenSSL releases, and - albeit
unsupported - LibreSSL.
- --sslcertck is now default.
- Optimized UIDL handling in POP3 configurations with --keep and servers
supporting the UIDL command. I meant to ship this only with fetchmail
7.0.x but there is no point in holding it back.
- .tar.bz2 is no longer created, the .tar.xz is much smaller and xz is
now mature and widely available.

Important non-changes:
- except where deprecated protocol versions are in use, the
configuration file and data files (.fetchids, .fetchmail.pid) should be
compatible with recent 6.3.X releases.

Future directions:
I intend to release fetchmail 6.4.0 formally in a few weeks, and abandon
the fetchmail 6.3.X branch (legacy_63). There are no features, and I
intend to keep the 6.4.X branch (legacy_64) only for important bug
fixes, features are merged onto the master branch that should end up as
fetchmail 7.0 some day.

The SSL changes in particular need thorough testing and possibly a bit
more documentation.
Let me know what you'll find. I am looking forward to your beta test
findings.

Happy fetching!

Matthias
