There was a comment in another thread (can't locate it at the moment) relating to a supposed V28 with the same functionality of menu items (the 3 visible items) as V26.09A but with the later OE V26 codebase - it wasn't suggested that it was an 'official' release, more of a 'next release above the one Martin has provided us'.

It doesn't help when those releasing the software patches can't change the version number - I have about 5 CD's cut with various versions.
