Ryan from SlicEdit tries to address some of the compatibility issues for plug-in developers that arise out of each release cycle. "If you develop a plug-in for Eclipse, you know that each release cycle you have to deal with new incompatibilities between your plug-in and the new version of Eclipse. There is always a plug-in migration guide to help you, and typically they do a pretty nice job. Every cycle though, there is usually some compatibility issues which arise that I have trouble finding any concrete information about, and eventually end up scouring random Internet threads and API docs for hours. Hopefully this post helps to eliminate one such problem for other developers," says Ryan.
If you have had issues in migrating plugins from older versions of Eclipse to the new versions, this post is worth a read. Of course, more pointers like these (apart from posts on bug trackers) can only help create large awareness for Eclipse plug-in developers.
