## Changes since 3.8.1

### 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 Please note that on Debian-based systems, PCRE (the old one, no longer maintained) is called "pcre3".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 Issue #4650: cyr_info(8) `conf`, `conf-all`, and `conf-default` subcommands no longer crash

- 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 #4710: crash on copy/append fail in mailbox with custom user flags

- Fixed: GETMETADATA no longer shows internal DAV mailboxes (unless `imapmagicplus` is enabled and the user is authenticated as `username+dav@domain`)

- 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

- Fixed Issue #4771: potential invalid read in message_parse_received_date (thanks Дилян Палаузов)

- Fixed Issue #4663: strip known-timezones from iCalendar object (thanks Дилян Палаузов)

- Fixed Issue #4722: failure in dav_reconstruct(1) when last message in mailbox was expunged (thanks Дилян Палаузов)

- Fixed Issue #4758: fix renaming mailbox between users

- Fixed Issue #4424: DAV requests now respond with 507 rather than 500 when mailbox_maxmessages limits exceeded

- Fixed Issue #4804: mailbox_maxmessages limits now applied correctly

- Fixed Issue #4785: crashes during TLS shutdown (thanks Дилян Палаузов)

- Fixed Issue #4820: PREVIEW message attribute must be qstring/literal, not an atom

- Fixed Issue #4828: the default addressbook can no longer be deleted

### Other changes

- Fixed Issue #4671: leniently handle unencoded valid UTF-8 strings in MIME headers

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