-current has moved to 7.4

With the following commit, Theo de Raadt (deraadt@) moved -current to version 7.4:

CVSROOT:	/cvs
Module name:	src
Changes by:	deraadt@cvs.openbsd.org	2023/09/26 07:27:32

Modified files:
	sys/conf       : newvers.sh 

Log message:
we are heading out of -beta

For those unfamiliar with the process: this is not the 7.4 release, but is part of the standard build-up to the release.

Remember: It's time to start using "-D snap" with pkg_add (and pkg_info).

(Regular readers will know what comes next…)
This serves as an excellent reminder to upgrade snapshots frequently, test both base and ports, and report problems [plus, of course, donate!].
