stupid question on OpenJPA's version : 1.2.1 = ready for production ?

[Jean-Baptiste BRIAUD -- Novlog]

Hi,
Suddenly, I'm wondering if OpenJPA version 1.2.1 is the lattest stable  
version or the "dev" version that will implement JPA 2.0 ?
In other words, witch one is the stable "production ready" version :  
1.2.1 or 1.1.0 ?
