We have just posted the second Release Candidate for .NET Micro Framework version 4.2.  We decided to do another release candidate so that we could take a few more features from the community and so that we could get a little more exposure to some fairly esoteric bug fixes.  So, in addition to the stuff that was already in 4.2, the new release includes:

- support for the STM32 family processors form ST Micro.  This port was contributed by Oberon Micro Systems (Cuno Pfister and Beat Heeb).  They have provided ports for the STM32 Stamp and for the MCBSTM32E development board.  EE Times already posted on this. 

- support for transcendental functions in System.Math contributed by Richard Scott.

- Several bug fixes from RC1

If you are not familiar with the term, a release candidate will be the final bits that we go with (ie no further changes are planned) unless there is something that is really broken.  The RC code is available at http://netmf.codeplex.com/SourceControl/changeset/changes/13011, Changeset 13011 and the pre-compiled PK and SDK are at  http://netmf.codeplex.com/releases/view/52341.

The planned release date is 9/12/2011.  As always, we look forward to your feedback. 

As a footnote, there is a new review of Cuno’s book at ZDNet UK
