After a long wait, I am happy to bring you the second beta release of the new Doctrine persistence layer for MongoDB. This release includes dozens of bug fixes and improvements and it is recommended that you upgrade as soon as possible. You can learn about how to get the code here.
About the Release
My full-time job is working at OpenSky, where we use the MongoDB ODM and many of the improvements and work are a result of the development we've been doing there. The changelog is very large as the development spanned almost 5 months with commits from over 15 developers all over the world. Here are some of the people who've contributed this release:
Check out the documentation as it is has been completely updated and improved for this release. We fully migrated the docs to use reST and Sphinx to generate our documentation so it is much improved over the previous versions.
Doctrine Project as a Whole
The MongoDB ODM is one of a few new projects under the Doctrine umbrella. You may also want to take a look at the CouchDB ODM and the PHP Content Repository ODM. These projects are all very exciting for the Doctrine Project but more for PHP as a whole. They are a new generation of libraries built for PHP 5.3 that bring a higher level of code quality to your PHP projects.
If you encounter any problems, bugs or issues please report them in Jira. If you have any questions you can try a mailing list or IRC. Read more about the Doctrine community here.
