-  - The API for the undo/redo features has been put into `re-frame.core`.
-    Detailed documentation is now available: https://github.com/Day8/re-frame/wiki/Undo-&-Redo
-    While undo and redo has been a part of re-frame from the beginning, the feature has been hidden
-    and not documented, so it is nice to see it given proper API status.
-    Plus, this release has [a couple of enhancements](https://github.com/Day8/re-frame/wiki/Undo-&-Redo#harvesting-and-re-instating)

-  - Thanks to @samroberton and @escherize, you can now run and debug your re-frame tests on the JVM.  
-    They've converted re-frame itself to `.cljc`, and stubbed out the necessary  `js` and `jvm` interop.
+  - You can now run and debug re-frame tests on the JVM.  This will be a really big deal for some.

+    Just to be clear: this does not mean you can run re-frame apps on the JVM (there's no React or 
+    Reagent available). But you can debug your handler tests using full JVM tooling goodness.
