JDO Hits Final
It's no longer news, and people are talking about it elsewhere, but it is still worth noting that JDO 2.0 released its final specficiation on May 1, 2006, and 10 days later, EJB 3 released its final specification.
Once again, we have to thank JDO's author and expert group lead, Craig Russell, whose diligent pursuit of simplicity and effectiveness has given rise to JDO, even as some controversy remains.
If you want to learn more about JDO 2.0, you may also want to take a look at its TCK, now available at Apache.org. JDO 2.0 is now a subproject of the Apache / DB project. Take a look, too, at the download page, where you can find the official release.
For an open-source reference implementation of JDO 2.0, take a look at JPOX 1.1.0.
