It gives me great pleasure to announce the release of STACK 4.1.
There are some important bug fixes and very useful additional interface features ("undeploy all") which I hope improve things. We strongly recommend you upgrade your existing servers.
I'm very grateful for the suggestions, code and examples from some new contributors. This is very welcome, and if you'd like to get involved you are welcome to contact me directly. Even improving the docs, contributing some example materials is welcome. I'd particularly appreciate some help with design and UI, so if you have these skills please do get involved.
I've released this today so we can upgrade our servers in Edinburgh in time for the start January teaching term. We do have a number of other new features (including a text-based markup language for questions, and I hope better support for numbers in base N) in the pipeline, so if we are able to do so there is likely to be another release before Easter.
