A few minutes ago we made available the 61214 release of the AJAX Control Toolkit. We did this in parallel with the release of the ASP.NET AJAX v1.0 RC in order to accommodate some breaking changes introduced in that release. Though we did not make any functional changes to the Toolkit in this release, we did take the opportunity to fix a handful of bugs that we'd found.
Recall that you can sample any of the controls right now (no install required). Then you can browse the project web site, download the latest Toolkit, and start creating your own controls and/or contributing to the project!
