The first Postfix 3.0 stable release candidate is out, to be followed
by the Postfix 3.0 stable release in a few days time.
You can review the RELEASE_NOTES file (on the source-code mirror
sites) for a long list of improvements, from main.cf/master.cf
syntax, DNS lookup result filters, and delivery status notification
filters, to work-in-progress support for internationalized email
addresses.
The experimental release Postfix-3.1-20150201 contains the same
code as the Postfix 3.0 stable release candidate.
