Hello Dovecot users,

Here is the Pigeonhole release candidate that goes with the Dovecot
v2.3 release candidate. Of course, a large part of this release consists
of compatibility changes for Dovecot v2.3. Apart from that, not much
changed, just a few additions and fixes that accumulated over the last
few months.

Most of these changes will be back-ported to Pigeonhole v0.4, but that
release will happen a little later.

Changelog v0.5.0:

* editheader extension: The implementation of header modifications is
  heavily updated. Although the functionality has not changed, the
  underlying code was updated to address several static analysis
  warnings, runtime integer arithmetic warnings (Clang), and to match
  updates in the Dovecot stream API.
+ variables extension: Made the maximum scope and variable size
+ subaddress: Support multiple recipient_delimiters.
- enotify extension: mailto method: Fixed parsing of mailto URI with
  only a header part.
- enotify plugin: mailto method: Make sure the "From:" header is set to
  a usable address and not "(null)".
- Fixed writing address headers to outgoing messages. Sometimes headers
  were MIME-encoded twice, yielding invalid results.

The release is available as follows:

Refer to and the Dovecot wiki for
more information. Have fun testing this release candidate and don't
hesitate to notify me when there are any problems.
