WordPress 2.7 Beta 1 has been released. I am going to test it with both the current version as well as the upcoming version to see if it works.
Also, the development of WordPress 2.7 is 2 weeks behind and hence 10th November will not be the release date for the final version, but rather a release candidate. The final version is expected to be at the end of November 2008.
Speaking of the final release, it will not be available on November 10th as originally scheduled. We are two weeks behind schedule at the moment. We need a little more time to finish the visual design, do a round of user testing against that finished design, and do a proper round of public beta testing. Our plan is to keep working as if Nov. 10 is still the release date. However, instead of releasing the final 2.7 on the 10th, we will make a release candidate available instead. The release candidate is intended to be a high-quality, almost-finished release that we are comfortable recommending for broad use. After Nov. 10, the focus will be on fixing high impact bugs turned up by those of you testing the release candidate. I suspect 2.7 will be ready for final release by the end of November. A specific date will be set as we progress through the public beta cycle and get a feel for how solid the release is.
