New ZFSSA code release today - 2010.Q3.4.2
By Steve Tunstall on Oct 06, 2011
A new code was released on MOS today. We are now on code 2010.Q3.4.2. (ak-2010.08.17.4.2)
Our minimum recommended version is still 2010.Q3.4.0, but if you have the time and opportunity to upgrade to this new Q3.4.2 release, it would be a very good idea. It includes many minor bug fixes. You can view the readme file it comes with to see what it includes.
Download it under the "patches & upgrades" tab in My Oracle Support.
