+ * Fix use of concurrent TLS connections under GnuTLS:
+ 80_01-GnuTLS-fix-hanging-callout-connections.patch
+ 80_02-GnuTLS-tls_write-wait-after-uncorking-the-session.patch
+ 80_03-GnuTLS-Do-not-care-about-corked-data-when-uncorking.patch

+ upstream git (already included in 4.94), on TLS connections to a CNAME
+ verify the certificate against the original CNAME instead of against
+ the A record. Closes: #985243
+ * In README.Debian explicitly document the limitation/extent of server
+ certificate checking (authenticity not enforced) in the default
+ configuration (Thanks, Jö Fahlke). This Closes: #985244 (improved
+ documentation and Closes: #985344 (Yes, without required cert
+ checking MitM attacks are possible, but for a stable update documenting
+ this is the best compromise.)
