[Fetchmail-devel] ANNOUNCE: fetchmail-6.4.2 has been released today, 2020-02-14 (fetchmailconf overhaul, bugfixes)

[Matthias A. <mat...@gm...>]

Greetings,

I have released fetchmail-6.4.2, it is available from sourceforge.net, see:
<https://sourceforge.net/projects/fetchmail/files/branch_6.4/>

It is a RECOMMENDED update for all users, it fixes one SSL bug, updates
the manual page and Chinese translation,
and brings fetchmailconf into the 2020's, by making it compatible with Python 3
(but it requires the future package, see below).

The distribution is now in lzip (*) format, but xz format remains available.

Older releases are herewith officially unsupported.

Status:

I plan to only do bug fixes to fetchmail-6.4.x so that upgrading
to newer 6.4.x releases should be acceptable under many "stable branch"
maintenance policies. More intrusive changes will happen to versions
that have higher numbers such as 6.5.y or 7.n.m (with m, n, y being numbers).


These are the release notes from NEWS:

--------------------------------------------------------------------------------
fetchmail-6.4.2 (released 2020-02-14, 27473 LoC):

## BREAKING CHANGES:
* fetchmailconf now supports Python 3 and currently requires the "future" 
  package, see https://pypi.org/project/future/.
* fetchmailconf: The minimum supported version is now Python 2.7.13, but it is 
  recommended to use at least 2.7.16 (due to its massive SSL updates).
  Older Python versions may check SSL certificates not strictly enough,
  which may cause fetchmail to complain later, if the certificate verify fails.
* fetchmailconf now autoprobes SSL-wrapped connections (ports 993 and 995 for 
  IMAP and POP3) as well and by preference.
* fetchmailconf now defaults newly created users to "ssl" if either of the
  existing users sets ssl, or if the server has freshly been probed and
  found supporting ssl.
  There is a caveat: adding a user to an existing server without probing it
  again may skip adding ssl. (This does not prevent STARTTLS.)

## BUG FIXES:
* Fix three bugs in fetchmail.man (one unterminated string to .IP macro, one
  line that ran into a .PP macro, .TH date format), and remove one .br request 
  from inside the table, which is unsupported by FreeBSD 12's mandoc(1) 
  formatter.  FreeBSD Bug#241032, reported by Helge Oldach.
* Further man page fixes and additions by Chris Mayo and Gregor Zattler.
* When evaluating the need for STARTTLS in non-default configurations (SSL 
  certificate validation turned off), fetchmail would only consider --sslproto 
  tls1 as requiring STARTTLS, now all non-empty protocol versions do.
* fetchmailconf now properly writes "no sslcertck" if sslcertck is disabled.
* fetchmailconf now catches and reports OS errors (including DNS errors) when 
  autoprobing.  Reported as Gitlab issue #12 by Sergey Alirzaev.
* fetchmailconf received a host of other bugfixes, see the Git commit log.

## CHANGES:
* Make t.smoke more robust and use temporary directory as FETCHMAILHOME, to make
  sure that the home directory resolves for the user running the test suite
  even if the environment isn't perfect. Reported by Konstantin Belousov,
  analysed by Corey Halpin, FreeBSD Bug#240914.
