To make life a bit easier, recent versions can now be accessed on the install page, http://pmem.uk/joinfs/install.html. This is in case you need to roll back to a previous version for whatever reason.
There is currently a minor instability since version 1.2.8. It might show up in other aircraft as systems being repeatedly switched on and off, or can be seen quite a lot in the shared cockpit as wandering instruments. There should be an attempted fix in 1.3.0 due out in a week or so.
