A member of the OpenSSL project gave me a "go ahead" and we now have branch:
https://svn.apache.org/repos/asf/httpd/httpd/branches/tlsv1.3-for-2.4.x as a copy of 2.4.x with 1827912,1827924,1827992,1828222,1828720,1828723,1833588,1833589,1839920,1839946 merged in. If was not a clean merge as some feature from trunk are not present in 2.4.x, so peer review/test is definitely desired. I put a backport proposal into 2.4.x/STATUS Cheers, Stefan > Am 03.09.2018 um 15:45 schrieb Jim Jagielski <j...@jagunet.com>: > > +1! for backporting > >> On Sep 3, 2018, at 5:17 AM, Stefan Eissing <stefan.eiss...@greenbytes.de> >> wrote: >> >> Dear SSL care takers and stake holders, >> >> trunk has TLSv1.3 support for some time.
