#acl PaulHowarth:read,write,admin,revert,delete All:read

=== Monday 9th August 2021 ===

==== Local Packages ====

 * Updated `dovecot`:
  * Updated `dovecot` to 2.3.16:
   * Any unexpected `exit()` will now result in a core dump; this can especially help notice problems when a Lua script causes `exit(0)`
   * `auth-worker` process is now restarted when the number of auth requests reaches `service auth-worker { service_count }`; the default is still unlimited
   * Event improvements: Added `data_stack_grow` event and `http-client` category; see https://doc.dovecot.org/admin_manual/list_of_events/
   * `oauth2`: Support RFC 7628 `openid-configuration` element, which allows clients to support `OAUTH2` for any server, not just a few hardcoded servers like they do now (see `openid_configuration_url` setting in `dovecot-oauth2.conf.ext`)
   * mysql: Single statements are no longer enclosed with `BEGIN`/`COMMIT`
   * `dovecot-sysreport --core` supports multiple core files now and does not require specifying the binary path
   * `imapc`: When `imap_acl` plugin is loaded and `imapc_features=acl` is used, `IMAP ACL` commands are proxied to the remote server; see https://doc.dovecot.org/configuration_manual/mail_location/imapc/
   * `dict-sql` now supports the "`UPSERT`" syntax for SQLite and PostgreSQL
   * `imap`: If IMAP client disconnects during a `COPY` command, the copying is aborted, and changes are reverted; this may help to avoid many email duplicates if client disconnects during `COPY` and retries it after reconnecting
   * `master` process was using 100% CPU if service attempted to create more processes due to `process_min_avail`, but `process_limit` was already reached (v2.3.15 regression)
   * Using attachment detection flags wrongly logged unnecessary "Failed to add attachment keywords" errors (v2.3.13 regression)
   * `IMAP QRESYNC`: Expunging UID 1 mail resulted in broken `VANISHED` response, which could have confused IMAP clients (v2.3.13 regression)
   * `imap`: `STORE` didn't send untagged replies for `\Seen` changes for (shared) mailboxes using `INDEXPVT` (v2.3.10 regression)
   * `rawlog_dir` setting would not log input that was pipelined after authentication command
   * Fixed potential infinite looping with autoexpunging
   * Log event exporter: Truncate long fields to 1000 bytes
   * `LAYOUT=index`: ACL inheritance didn't work when creating mailboxes
   * Event filters: Unquoted '`?`' wildcard caused a crash at startup
   * `fs-metawrap`: Fix to handling zero sized files
   * `imap-hibernate`: Fixed potential crash at de-init
   * `acl`: `dovecot-acl-list` files were written for `acl_ignore_namespaces`
   * `program-client` (used by Sieve `extprograms`, `director_flush_socket`) may have missed status response from UNIX and network sockets, resulting in unexpected failures
  * Updated `pigeonhole` to 0.5.16:
   * `.dovecot.sieve.log` file now includes year in the header
   * Change Sieve script result execution to delay definitive action execution to the end of a successful Sieve script execution session, which is part of an effort to solve problems with the Sieve duplicate test; as a side-effect, some rare temporary-error cases yield different results, in which partial failure is more likely
 * Updated `nmap` to 7.92 (see [[https://github.com/nmap/nmap/blob/0d2323f0397d058fce16f5000c8f5397466aab52/CHANGELOG|CHANGELOG]] for details)
