Released Pigeonhole v0.4.10.rc2 for Dovecot v2.2.20

[Stephan Bosch]

Hello Dovecot users,

Here's the Pigeonhole RC that goes with Dovecot v2.2.20. Due to the
earlier described conflict, RC1 will not compile with the new Dovecot
release.

I am not really in hurry to make a definitive release of Pigeonhole,
since v0.4.9 still compiles fine with Dovecot v2.2.20. Still, if no big
bugs emerge in the next few days, I will make a final release. So,
please test this new RC and especially the new features.

Changelog v0.4.10:

+ Implemented the Sieve mime and foreverypart extensions (RFC 5703).
  These are fully implemented. The interaction with the editheader
  extension needs some work, but this should not influence most uses;
  i.e., changes by the editheader extension are not always visible
  using foreverypart/mime.
+ Sieve body extension: Properly implemented the `:text' body
  transform. It now extracts text for HTML message parts.
+ Sieve enotify extension: mailto method: Implemented the
  sieve_notify_mailto_envelope_from setting. This allows configuring
  the source of the notification sender address for e-mail
  notifications. This is similar to what already can be configured for
  redirect.
+ Added a sieve_enabled (defaults to 'yes') setting that allows
  explicitly disabling Sieve processing for particular users. This used
  to be possible by setting `sieve=', but ever since the sieve_before,
  sieve_after and sieve_default settings were added, this method was
  not reliable anymore.
- variables extension: Fixed handling of empty string by the `:length'
  set modifier. An empty string yielded an empty string rather than "0".
- Fixed memory leak in the Sieve script byte code dumping facility.
  Extension contexts were never actually freed.
- Fixed handling of implicit keep when the last Sieve script is a
  global one. In that case the implicit keep action was executed in
  global context, which could mean that trivial (quota) errors ended up
  in the system log file, rather than the user log file.
- doveadm sieve plugin: Fixed crashes caused by incorrect context
  allocation in the sieve command implementations.

The release is available as follows:

hesitate to notify me when there are any problems.
