Database Mirroring is available on SQL 2005 SP1 onwards. It is built in to the RTM versions of all more recent versions of SQL Server.
There will be fixes for data mirroring problems in all SPs of all versions, and in most CUs. It is best for a new build to be using the latest SP and CU.
Although Data Mirroring is deprecated, it will still be available in SQL 2016. From SQL 2016 onwards there is a basic form of Availability Groups that will replace database mirroring in subsequent versions of SQL Server.
