After today's update there's an incomaptibility between biber and
biblatex that prevents working with biber at all. Here's what I get on
INFO - This is Biber 2.7
INFO - Logfile is 'testfile.blg'
INFO - Reading 'testfile.bcf'
ERROR - Error: Found biblatex control file version 3.4, expected version 3.3.
This means that your biber (2.7) and biblatex (3.8) versions are incompatible.
See compat matrix in biblatex or biber PDF documentation.
INFO - ERRORS: 1
CTAN received yesterday night an update of biblatex to Version 3.8.
The comment said that this required biber 2.8 .
However, AFAICS biber has not yet been updated on CTAN.
Moreover, we received this morning a re-upload of a "corrected
biblatex 3.8" that was still labelled "3.8".
I asked for a re-upload of the same, but with a slightly
increased version number, to avoid confusion.
At the moment, we have not got any further.
Therefore I'd recommend, for the time being, that TeX Live
revert to biblatex 3.7.
