Patch release dates are always tentative so I'm afraid that's as good as its likely to get. The best I can say is it should release very soon.
You can sign up for McAfee's Support Notification Service (SNS) here to receive an email notification when it does release: http://my.mcafee.com/content/SNS_Subscription_Center
it is out now and available for download.
Where can I find the patch ?
On product download site is only the complete installation file.
The patch and full install are the same file. At least that's my understanding. I installed it today on a test system and had no issues. Also upgraded a test Agent Handler, and again no issues.
