5.0.11 was released a couple of days ago and the 5.0 branch is closed.

IIRC it doesn't cause any problem in 5.0 because all the calls are from
C and C does not expect %ecx to be preserved across calls.  In 5.1
console_putc is done totally differently and the PM to RM switch saves
%ecx.

No, you'll have to wait for 5.3. 5.1 is virtually closed except for some
last minute cleanups by me and will become 5.2 within a few days.

This is what I was trying to hint to you: 5.0 is no longer being
developed and 5.1 does things underneath rather differently.
