[tex-live] biber and biblatex incomaptible

[Uwe Siart]

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
the command line (win32):

d:\>biber testfile
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
