Hi, First let me say Thank you Emmanuel for your great work in the last days fixing some old bugs and applying some of the patches that were sleeping in the Jira :-) I have hope that someday i can build Sequoia from the SVN directly :-)
To the future plans. I must stand up and raise my finger, i can't find any point about making Sequoia stable. The last point in 4.x is the only thing that goes this way. I hope i can help you as much as i can with the Test Suite and writing Tests. Another feature/bug* that would make Sequoia more stable is the WAN-scenario that is not yet supported by Sequoia. Any Ideas?
