Re: [isabelle] Isabelle2021-1-RC3 available for testing

Hi List.

Following my experience report on porting isabelle-llvm from 2021 to
Summary: roughly 7h work for 70kLOC.
Fixing violations of context discipline took a while, and bigger
changes in word library (again) were getting a little annoying.
Otherwise, everything worked well.

Apart from the separate emails I already sent, one minor point I
noticed: substitutions work with a more efficient data structure now.
However, the existing NEWS entry does not mention Variable.import, 
where this change caused type errors for me at several points. 
Thus, I needed some time to find the relevant NEWS entry.
