As outlined in the 3.0 plan, the
eclipse team firmly believes in preserving API compatability. With this
mindset the team has produced a propsal that results in a good overall
Eclipse solution while keeping most API intact. There is a bugzilla report
for this plan item and documentation available on the UI team's home page.
If you are interested in this work or
are concerned about the proposed API changes I encourage you to review
the available information and send your comments to the platform-ui-dev@xxxxxxxxxxx
mailing list.
