Unbound 1.19.3rc2 pre-release

Hi Wouter,

I tried out 1.19.3rc2 and I still see the same issue:

unbound-checkconf: no errors in C:\Program Files\Unbound\service.conf
error: could not SSL_read
185B0000:error:0A000418:SSL routines:ssl3_read_bytes:tlsv1 alert unknown ca:ssl/record/rec_layer_s3.c:865:SSL alert number 48

Hi,

Unbound 1.19.3rc2 pre-release is available:
https://nlnetlabs.nl/downloads/unbound/unbound-1.19.3rc2.tar.gz
sha256 d5519cdd078d29c2b16bbebf7361374e356b79e8632e6e2c9f1dbe2532518eec
pgp https://nlnetlabs.nl/downloads/unbound/unbound-1.19.3rc2.tar.gz.asc

This is RC2 of the 1.19.3rc2 pre-release of Unbound.

The changes in RC2 compared to RC1 are an update to the windows unbound-control-setup.cmd, so that it creates valid self-signed certificates for use with unbound-control. And a fix for the synthesized CNAME ttl value.

Bug Fixes:
- Fix unbound-control-setup.cmd to use 3072 bits so that certificates
   are long enough for newer OpenSSL versions.
- Fix TTL of synthesized CNAME when a DNAME is used from cache.
- Fix unbound-control-setup.cmd to have CA v3 basicConstraints,
   like unbound-control-setup.sh has.

Best regards, Wouter
