=== Monday 26th December 2022 ===

==== Fedora Project ====

 * Updated `perl-JSON-PP` to 4.14:
  * Break up `099_binary.t` into 16 pieces that can be tested in parallel ([[https://github.com/makamaka/JSON-PP/pull/80|GH#80]])

==== Local Packages ====

 * Updated `dovecot` (2.3.x):
  * Updated dovecot to 2.3.20:
   * Add `dsync_features=no-header-hashes`
   . When this setting is enabled and one dsync side doesn't support mail GUIDs (i.e. `imapc`), there is no fallback to using header hashes; instead, dsync assumes that all mails with identical IMAP UIDs contains the same mail contents, which can significantly improve dsync performance with some IMAP servers that don't support caching `Date`/`Message-ID` headers
   * lua: HTTP client has more settings now (see https://doc.dovecot.org/admin_manual/lua/#dovecot.http.client)
   * replicator: "doveadm replicator status" command now outputs when the next sync is expected for the user
   * `LAYOUT=index`: Duplicate GUIDs were not cleaned out; also, the list recovery was not optimal
   * auth: Assert crash would occur when iterating multiple userdb backends
   * director: Logging into director using master user with `auth_master_user_separator character` redirected user to a wrong backend, unless `master_user_separator` setting was also set to the same value; merged these into `auth_master_user_separator`
   * dsync: Couldn't always fix folder GUID conflicts automatically with Maildir format; this resulted in replication repeatedly failing with "Remote lost mailbox GUID"
   * dsync: Failed to migrate INBOX when using `namespace prefix=INBOX/`, resulting in "Remote lost mailbox GUID" errors
   * dsync: INBOX was created too early with `namespace prefix=INBOX/`, resulting in a GUID conflict; this may have been resolved automatically, but not always
   * dsync: v2.3.18 regression: Wrong imapc password with dsync caused `Panic: file lib-event.c: line 506 (event_pop_global): assertion failed: (event == current_global_event)`
   * imapc: Requesting `STATUS` for a mailbox with `imapc` and `INDEXPVT` configured did not return correct (private) unseen counts
   * lib-dict: Process would crash when committing data to redis without dict proxy
   * lib-mail: Corrupted cached `BODYSTRUCTURE` caused panic during `FETCH` (v2.3.13 regression)
   . Fixes: `Panic: file message-part-data.c: line 579 (message_part_is_attachment): assertion failed: (data != NULL)`
   * lib-storage: `mail_attribute_dict` with `dict-sql` failed when it tried to lookup empty dict keys
   * lib: `ioloop-kqueue` was missing include, breaking some BSD builds
   * lua-http: Dovecot Lua HTTP client could not resolve DNS names in mail processes, because it expected "dns-client" socket to exist in the current directory
   * oauth2: Using `%{oauth2:name}` variables could cause useless introspections
   * pop3: Sending POP3 command with '`:`' character caused an assert-crash (v2.3.18 regression)
   * replicator: Replication queue had various issues, potentially causing replication requests to become stuck
   * stats: Invalid Prometheus label names were created with specific histogram `group_by` configurations; Prometheus rejected these labels
  * Updated pigeonhole to 0.5.20:
   * No changes - release done to keep version numbers synced
 * Updated `perl-JSON-PP` to 4.14 as per the Fedora version
