Best practices around Silverlight 2 GDR 1?

Question

I noticed a few tweets this morning about a new version of Silverlight having been released - Silverlight 2 GDR 1 (2.0.40115.0). Details of what/why/should I target it/is it backward compatible/etc seem incredibly thin on the ground.

Hitting this Silverlight page on Microsoft.com tells me my version (RTW) is now out of date and I should upgrade to GDR 1. But hitting silverlight.net - there's no mention of it, the Silverlight elements on the page don't tell me my version is out of date and the Getting Started page still links to RTW tools.

This kinda leads me to presume that if you upgrade your dev tools to target the GDR release, then your users will need to upgrade their Silverlight install also?

A few details on what's in GDR can be found in the release notes - but it sure would be nice if Microsoft would clarify it's purpose and suggested adoption. Anyone got any more details?

Answer 1

It seems to be only bug fixing.

So if your applications (so your users) are not concerned by those bugs, it is not mandatory to update your plugin for the moment.
