Undisclosed Integrator #1,
“I didn't think it was too much to ask to have access to new features for testing as soon as they are made available.” – You still have not asked.
Not sure you have adequate knowledge about me to know how I feel.
Our development partner agreed with shutting down the page you reference.
And yes I am well aware that all new releases were not posted to our site at the same time as the page you mention, which was never meant to be public. Since we are in the front line position to support all new releases, there are items we need fixed prior to release. Being the keen observer of the private page you reference, I am sure you noticed some of the patches that quickly followed each release; our support team may have had something to do with some of these patches.
Release notes are on our website - Release Notes
The DW Spectrum page on our website contains version 3.1, version 3.0 and a current link to previous versions.
