I received an email from the TechNet evaluation Centre this morning, stating that the CTP for SQL Server 2016 (v2.2) has been replaced as of yesterday. Apparently the previous release caused downtime with AlwaysOn Availability Groups during rolling upgrades. Though I have SQL Server 2016 installed on an Azure box, I’ve not played around with AlwaysOn in 2016. An upgrade is recommended for any users who wish to upgrade to SQL Server 2016 CTP 2.2, including AlwaysOn users. If you have already downloaded the English parts from 28th July onwards, you already have the latest build. The previous release for CTP 2.2 was 23rd of July.
