Is there a SQL Server 2008 R2 specific target for SSDT projects?

I am making a SQLCLR stored procedure in Visual Studio 2012. I have these options for target platform:

Is there not a SQL Server 2008 R2 specific option? Is this because SQL 2008 R2 shares the same compatibility level of 100 with SQL Server 2008?

A 2008 and 2008R2 user database is schema compatible, hence one version for both in SSDT. In other words, there aren't any schema objects that you could add to a 2008R2 SSDT model that couldn't be created in 2008.

This isn't the same as either database version or database compatibility level.

Database version:


The database version is a number stamped in the boot page of a
database that indicates the SQL Server version of the most recent SQL
Server instance the database was attached to. The database version
number does not equal the SQL Server version.

Database compatibility level:


The database compatibility level determines how certain database
behaviors work. For instance, in 90 compatibility, you need to use the
OUTER JOIN syntax to do an outer join, whereas in earlier
compatibility levels, you can use = and =.
