As I mentioned a while back, Eclipse Helios M5 was made available for Download. There are number of New and Noteworthy features, but one really big feature was omitted from the N&N. The Eclipse provisioning platform, p2, finally has API! Really, go take a look at the code… all those internal.provisional packages are now gone!  This was actually a huge milestone for the p2 team, and Pascal did a great job steering us towards the API.

What does this mean to you? Well, if you are building anything on top of p2 you should grab M5 and see how the new API feels. We are going to be pushing hard to finalize the API for M6, so if there is anything missing, speak up now.
