From the Erlang mailing list:
"This release is mainly a stabilization of the R14A release (which was a beta) but there are some new functionality also."
"This release is mainly a stabilization of the R14A release (which was a beta) but there are some new functionality also."
The R14B release is the real release of R14. Will then be incremented with R14B-1 etc.
I would recommend Erlang developers to use the B releases in development, but wait for the B-1 release before upgrading production servers.
