Steven released a new patch #474, it is available at
ftp://ftp.2bsd.com/2.11BSD/474
https://www.retro11.de/data/211bsd/patches/474
the other mirrors will follow soon.

This patch is probably the smallest ever made, exactly 2 bits changed in the
source code if you ignore comment changes. And in the compiled kernel also
only two bits are changed. The patch is a follow-up of patch #150, see
https://www.retro11.de/data/211bsd/patches/150
which was issued on August 23rd, 1993. So final touches come now, to the
day, 29 years later. Probably another record.

And what is it about: get the stack extension logic right on J11-based systems.
The full story is in #474 and #150. It came up as part of the 'MMR1 mysteries'
activities.
