The biber package is now at 2.14, but TextBibTeX is still required.
Few changes were needed for newly introduced scripts-extra path. This
broke some of our old tricks which were relying on having writable
script directories. The changes to the script locations made buildEnv
create symlinks to the script directories instead of directories of
symlinks to scripts. The changes to texlinks.sh and texlive/TeXLive
perl path were made because of this.
