The roadmap to Thunderbird 3 will look to include calendaring functions putting it on a par with Microsoft’s Outlook as well as migrating the entire MailNews framework (Netscape Communicator anyone?) which went onto become Mozilla Thunderbird from the old RDF/Mork framework to the new SQLite based MozStorage which also makes an appearance in Firefox 3.0.
Also included in Thunderbird 3.0 will be STEEL which is like Firefox’s FUEL extension library.
