## Changes since 3.4.6

### Build changes

- Fixed: Cassandane tests now pass on Debian Bookworm

- PCRE2 is now supported and detected with pkg-config. If both PCRE and PCRE2 are available, the older PCRE will be preferred. To force use of PCRE2 in this situation, run configure with the `--disable-pcre` option. Please note that on Debian-based systems, PCRE (the old one, no longer maintained) is called "pcre3". Yes, this is confusing.

- Fixed Issue #4770: missing include when ssl unavailable (thanks Дилян Палаузов)

### Bug fixes

- Fixed: squat db reindexes are no longer always incremental

- Fixed: squat db corruption from unintentional indexing of fields intended to be skipped. Squat search databases may benefit from a full (non-incremental) reindex

- Fixed Issue #4660: squat db out of bounds access in incremental reindex docID map

- Fixed Issue #4692: squat db searches now handle unindexed messages correctly again (thanks Gabriele Bulfon)

- Fixed Issue #4717: pop3d now avoids splitting `".\r\n"` across packet boundaries, which can confuse some clients

- Fixed Issue #4756: potential uninitialized access in extract_convdata

### Other changes

- Fixed Issue #4790: some man pages were missing from distribution tarballs (thanks Jakob Gahde)
