pdfcomment.sty v2.4a
I’ve just uploaded the new version v2.4a to Bitbucket. The following excerpt from the README briefly describes the new version:
Changes in v2.4a:
fix issue #22: fix "Wrong driver 'hpdftex.def'" warning when using lualatex
The new version v2.4a is already available on CTAN and surely soon in the package managers of the distributions.
