michaelhkay: Saxon 9.3 has been out for 8 days: only two bugs so far, one found by me. I think that's a record.

Not necessary. We, for example, who use Saxon HE, have found nothing new in Saxon 9.3, while expected to see xslt 3.0. Disappointed. No actual reason to migrate.

P.S. We were among the first who were finding early bugs in previous releases.
