Happy New Year!
WaveMaker 6.5.2 is a bug fix release that resolves a couple important issues, most notably the Java Types issue (WM-4717). We recommend that anyone using WaveMaker 6.5.x upgrade to 6.5.2.

For the complete list of fixes see the WaveMaker 6.5.2 Release Notes.
I expect that WaveMaker 6.5.2 will provide the functionality and stability to enable you to deliver on your ambitious goals for 2013. If your goals for 2013 are not ambitious, WaveMaker 6.5.2 will work for you too. 🙂
