Dovecot news - Mar 2016 - Released Pigeonhole v0.4.13.rc1 for Dovecot v2.2.22.rc1.

Hello Dovecot users,

Pigeonhole v0.4.12 still compiles against Dovecot v2.2.22.rc1, but only
with warnings. That is the primary reason for this new release. However,
there are also a few significant changes as listed below. When no
significant problems are reported, a definitive release will follow
closely after Dovecot v2.2.22 is released.

Changelog v0.4.13:

* redirect action: Added the list-id header to the duplicate ID for
  mail loop prevention. This means that the message sent directly to
  the user and the message coming through the mailing list itself are
  treated as different messages by the loop detection of the redirect
  command, even though their Message-ID may be identical.
* Changed the Sieve number type to uint64_t, which means that Sieve
  numbers can now technically range up to 2^64. Some other Sieve
  implementation allowed this, making this change necessary for
  successful migration.
+ Implemented the sieve_implicit_extensions setting. The extensions
  listed in this setting do not need to be enabled explicitly using the
  Sieve "require" command. This behavior directkly violates the
  standard, but can be necessary for compatibility with some existing
  implementations of Sieve. Do not use this setting unless you really
  need to!
- redirect action: Made mail loop detection more robust by forcibly
  adding a Message-ID header if it is missing.
- Prevent logging a useless "script not found" error message for LDAP
  scripts for which the entry exists but no attribute containing a
  script. This is not necessarily an error.
- extprograms plugin: Changed the communication channel between parent
  and child process for a directly forked program from a socketpair to
  a double pipe. Linux does not support /dev/stdin, /dev/stdout and
  friends for sockets. For some shell program authors this may be
  confusing, so that is why it is changed. When using the script
  service, these device nodes are still not usable though.

The release is available as follows:
