** Flymake
+++
-*** Emacs no longer prompts the user before killing Flymake processes on exit.
+*** Flymake has been completely redesigned
+
+Flymake now annotates arbitrary buffer regions, not just lines. It
+supports arbitrary diagnostic types, not just errors and warnings (see
+variable 'flymake-diagnostic-types-alist').
+
+It also supports multiple simultaneous backends, meaning that you can
+check your buffer from different perspectives (see variable
+'flymake-diagnostic-functions'). Backends for Emacs Lisp mode are
+provided.
+
+The old Flymake behaviour is preserved in the so-called "legacy
+backend", which has been updated to benefit from the new UI features.
