Learn about how to interface to this framework. The data model is pretty much unchanged, although there are some new tables in the database corresponding to new functionality. An upgrade to version 0.2 should come relatively painlessly. One big piece of functionality to be included is the new alerts system. Each event carries with it a description of how it originated, and the handlers are polled to see if any are interested in each alert.
Handlers execute arbitrary code out of the database for fully scripted responses to alerts.
User account management is sporting more features, with a variety of options for email verification of new accounts, manager approval before account activation, or a combination of the two being supported alongside instant approval. Or if you find bugs or incompatibilities with the 0.1 version, I'd appreciate knowing about that too. Integrated management tools make it easy to manipulate counter records in the database, and including a counter in a file is a one-line matter. The counter tool then makes getting information about the current counter for in-page display very straightforward. The parser comes in handy for guestbooks, weblogs, forums, etc.
