+This is the first preview release of Samba 4.10. This is *not*
intended for production environments and is designed for testing
purposes only. Please report any defects via the Samba bug reporting
system at https://bugzilla.samba.org/.
-Samba 4.4 will be the next version of the Samba suite.
+Samba 4.10 will be the next version of the Samba suite.
UPGRADING
=========
-Nothing special.
-NEW FEATURES
-============
-
-Flush requests from SMB2/3 clients are handled asynchronously and do
-not block the processing of other requests. Note that 'strict sync'
-has to be set to 'yes' for Samba to honor flush requests from SMB
-clients.
-
-WINS nsswitch module
+NEW FEATURES/CHANGES
====================
-The WINS nsswitch module has been rewritten to address memory issues and to
-simplify the code. The module now uses libwbclient to do WINS queries. This
-means that winbind needs to be running in order to resolve WINS names using
-the nss_wins module. This does not affect smbd.

-Changes
-#######
-
-smb.conf changes
-----------------
-
- Parameter Name Description Default
- -------------- ----------- -------
- aio max threads New 100
-
-CTDB changes
-------------
-
-* CTDB now uses a newly implemented parallel database recovery scheme
- that avoids deadlocks with smbd.
-
- In certain circumstances CTDB and smbd could deadlock. The new
- recovery implementation avoid this. It also provides improved
- recovery performance.
-
-* All files are now installed into and referred to by the paths
- configured at build time. Therefore, CTDB will now work properly
- when installed into the default location at /usr/local.
-
-* Public CTDB header files are no longer installed, since Samba and
- CTDB are built from within the same source tree.
-* CTDB_DBDIR can now be set to tmpfs[:<tmpfs-options>]
+REMOVED FEATURES
+================
- This will cause volatile TDBs to be located in a tmpfs. This can
- help to avoid performance problems associated with contention on the
- disk where volatile TDBs are usually stored. See ctdbd.conf(5) for
- more details.
-* Configuration variable CTDB_NATGW_SLAVE_ONLY is no longer used.
- Instead, nodes should be annotated with the "slave-only" option in
- the CTDB NAT gateway nodes file. This file must be consistent
- across nodes in a NAT gateway group. See ctdbd.conf(5) for more
- details.
-
-* New event script 05.system allows various system resources to be
- monitored
-
- This can be helpful for explaining poor performance or unexpected
- behaviour. New configuration variables are
- CTDB_MONITOR_FILESYSTEM_USAGE, CTDB_MONITOR_MEMORY_USAGE and
- CTDB_MONITOR_SWAP_USAGE. Default values cause warnings to be
- logged. See the SYSTEM RESOURCE MONITORING CONFIGURATION in
- ctdbd.conf(5) for more information.
-
- The memory, swap and filesystem usage monitoring previously found in
- 00.ctdb and 40.fs_use is no longer available. Therefore,
- configuration variables CTDB_CHECK_FS_USE, CTDB_MONITOR_FREE_MEMORY,
- CTDB_MONITOR_FREE_MEMORY_WARN and CTDB_CHECK_SWAP_IS_NOT_USED are
- now ignored.
-
-* The 62.cnfs eventscript has been removed. To get a similar effect
- just do something like this:
-
- mmaddcallback ctdb-disable-on-quorumLoss \
- --command /usr/bin/ctdb \
- --event quorumLoss --parms "disable"
-
- mmaddcallback ctdb-enable-on-quorumReached \
- --command /usr/bin/ctdb \
- --event quorumReached --parms "enable"
-
-* The CTDB tunable parameter EventScriptTimeoutCount has been renamed
- to MonitorTimeoutCount
-
- It has only ever been used to limit timed-out monitor events.
-
- Configurations containing CTDB_SET_EventScriptTimeoutCount=<n> will
- cause CTDB to fail at startup. Useful messages will be logged.
-
-* The commandline option "-n all" to CTDB tool has been removed.
+smb.conf changes
+================
- The option was not uniformly implemented for all the commands.
- Instead of command "ctdb ip -n all", use "ctdb ip all".
+ Parameter Name Description Default
+ -------------- ----------- -------
-* All CTDB current manual pages are now correctly installed
