Version 0.7a (2019-04-04)

See v0.7...v0.7a

Fixed

• Bug in the env option to \printbibtabular. The old version would
  check for a bib environment as defined with \defbibenvironment
  and not a bibtabular environment as defined with \defbibtabular.
  Hence, the option would throw an error if there was no bib
  environment of the same name as the bibtabular environment passed
  to env.

Changed

• biblatex-ext-doiapi warns about missing email just a tad earlier.
