-The smb.conf parameter "write cache size" has been removed.
-
-Since the in-memory write caching code was written, our write path has
-changed significantly. In particular we have gained very flexible
-support for async I/O, with the new linux io_uring interface in
-development. The old write cache concept which cached data in main
-memory followed by a blocking pwrite no longer gives any improvement
-on modern systems, and may make performance worse on memory-contrained
-systems, so this functionality should not be enabled in core smbd
-code.
-
-In addition, it complicated the write code, which is a performance
-critical code path.
-
-If required for specialist purposes, it can be recreated as a VFS
-module.

-BIND9_FLATFILE deprecated
--------------------------
-
-The BIND9_FLATFILE DNS backend is deprecated in this release and will
-be removed in the future. This was only practically useful on a single
-domain controller or under expert care and supervision.
-
-This release removes the "rndc command" smb.conf parameter, which
-supported this configuration by writing out a list of DCs permitted to
-make changes to the DNS Zone and nudging the 'named' server if a new
-DC was added to the domain. Administrators using BIND9_FLATFILE will
-need to maintain this manually from now on.
-
-
-Retiring DES encryption types in Kerberos.
-------------------------------------------
-With this release, support for DES encryption types has been removed from
-Samba, and setting DES_ONLY flag for an account will cause Kerberos
-authentication to fail for that account (see RFC-6649).
-
-Samba-DC: DES keys no longer saved in DB.
------------------------------------------
-When a new password is set for an account, Samba DC will store random keys
-in DB instead of DES keys derived from the password. If the account is being
-migrated to Windbows or to an older version of Samba in order to use DES keys,
-the password must be reset to make it work.
-
-Heimdal-DC: removal of weak-crypto.
------------------------------------
-Following removal of DES encryption types from Samba, the embedded Heimdal
-build has been updated to not compile weak crypto code (HEIM_WEAK_CRYPTO).
-
-CTDB changes
-------------
-
-* The ctdb_mutex_fcntl_helper periodically re-checks the lock file
-
- The re-check period is specified using a 2nd argument to this
- helper. The default re-check period is 5s.
-
- If the file no longer exists or the inode number changes then the
- helper exits. This triggers an election.
