[plt-scheme] Announce: mzgtk2 release 2 version 2.6.10.002

The "mred is based on wx windows" thought is so very very old.

mred is completely rewritten and has been under very active
development for a very long time. There are lots of things that parts
of our system are "based on" from more than a decade ago.

Its not relevant anymore.
