The new version (WeBWorK-2.7) of WeBWorK has been merged into the "master" branch on github.com/openwebwork. If you are already using version 2.6 from the master branch then updating from github will get the new software with the new features. There are instructions and release notes at http://webwork.maa.org/wiki/Release_notes_for_WeBWorK_2.7
WeBWorK-2.7 is what you should plan to be using for this coming fall.
For those using software from the SVN repository there are instructions for switching over safely. (The use of github makes it much easier to upgrade in the future and to back out to earlier versions if that is desired.)
The separate branch release/2.7 in github.com/openwebwork has been completely merged into the master branch and is no longer needed. It will be removed shortly. The same 2.7 software can now be obtained by "pulling" from the master branch.
Within a few weeks we hope to have a new release candidate release/2.8. We are building toward a significant overhaul of the instructor's user interface which will make it more web2.0 interactive. The reports we hear so far are that the student interface already works well, even on tablets, so we will be more cautious about making changes on that aspect of WeBWorK.
There are several initiatives this summer to reorganize the OpenProblemLibrary, to organize problems sets for modelCourses (Calc1, MultiVariableCalc, Statistics1, et.) and to create and improve problem types such as those using Sage interacts and "compound" or "progressive" problems which present questions sequentially.
Many features of this release have been developed at the code camps
WeBWorK::Rochester, WeBWorK::Winona, WeBWorK::Fitchburg, WeBWorK::Raleigh, WeBWorK::AnnArbor. (see the blogs linked to http://webwork.maa.org/planet for news about camps and the features developed). Thanks to all those participants and to everyone else who has contributed to this new release. Next planned code camp is WeBWorK::Vancouver. Anyone interested in organizing, helping to organize, or participating in a code camp to work on WeBWorK projects please feel free step up, and to contact me (Mike Gage) if you wish help or advice.
Enjoy the new release. I encourage those who helped build this release to continue to write blog posts describing the new features and how to use them. We'll also create more permanent "manual" pages on the wiki.
