This is a specific list of the features needed to make releases towards Jython 2.5. The first alpha will be made once Jython supports all CPython 2.5 language level features. After the alphas have stabilized, all the library and Jython-only features will be completed in the beta series of releases. Once all the features are present in the betas, we'll go into release candidate mode until 2.5 is finally released.
Just because a feature is in the beta list, that doesn't mean it can't land before the alpha release. It only means it isn't necessary before the alpha. Actually since all of the alpha features are dependent on the new compiler and parser, the beta tasks can be a good starting point. PEPs 292, 305, 324 and 327 should be doable with trunk as can the template removal tasks and bugtests migration at the end of the list.

- Move antlr parser in /trunk/sandbox/ast to trunk
- Translate summer of code compiler to Java and hook up to antlr
