Hi All, Just received my NerdKit and was downloading the docs, tools, etc.

Quick question: I notice that the release on the NerdKits website for WinAVR is 20090313. If you go to WinAVR there is an updated stable release 20100110. I know WinAVR is a collection of different GNU tools, is there any reason not to go ahead and use the more current release of WinAVR?

No reason that I know of. I've been using the 2010 version for a while with no new problems.

But that leads to the classical question of why? Is there a overwhelming reason to upgrade beyond the fact that it is there?

This is a nagging question for all software (and device) users and developers.

If it works why upgrade?

I know crizzo99's question was about just starting out and in fact I would encourage him to use the latest "stable" release but thought

I'd just ask for us using WinAVR 20090313 is there anything in the newer release that might add a advantage?

I know "RTFM", sorry.

I upgraded because of bugs they fixed. Even things as common as the util/delay routines have bug fixes.
