I think GP is referring to the 2.9 release (or was it 2.8 or 3.0?) that had a major UI overhaul a few years back, I would say that the real explosion of Blender usage co-incided with that release.
Coming from 3ds, 3dsmax and Lightwave mainly (some Maya), I had previously tried Blender a couple of times and usually rage-quite within 15 minutes due to the flaky-feeling UI.
After actually using that big UI release I went back to the previous major release to see what I had missed.
The general context (mesh mode->mesh edit->vertices) that in newer releases is placed somewhat in a sane order, was placed so that your major context was selected in the _middle of the screen_, then secondary was at the top and tertiary somewhere else.
That's just a big no-no in terms of UI design but had probably made some sense when Blender evolved and people who got used to Blender had probably internalized it (and staunchly defended it).
No they probably do mean the jump between the interface in 2.49 which was somewhat unique and very, very different to the current UI, to that in 2.5 which the current interface mostly resembles. 2.8 was a smaller jump that introduced left click select as the default, along with various cosmetic enhancements and a rework of the depsgraph.No idea what you're talking about with contexts being selected in the middle of the screen etc. I suspect you're using "context" in a way unique to you
