Release Notes: ECB offers now two new interactors (special ECB windows): one for the semantic analyser (of cedet) and one for displaying the definition of the current symbol at point. In addition, the up and down arrow keys are now smart in the tree buffers. Much better maximizing and minimizing of the ECB windows was implemented. Support for (X)Emacs < 21 has been officially removed. Full documentation of the tree-buffer.el library was provided. Some important bugfixes were made.
Release Notes: Sorting of the Sources-buffer and the History-buffer is now more flexible. Bugs were fixed.
