Description Michael Catanzaro 2017-05-15 18:10:31 PDT 
Based on discussion with Nikos in https://bugzilla.gnome.org/show_bug.cgi?id=782218, we should remove LATEST_RECORD_VERSION from our GnuTLS priority string. This causes GnuTLS to use the latest TLS record version (the record format is separate from the TLS protocol version), which we needed a couple years ago (after dropping SSLv3) for maximum compatibility with broken web servers. But it's not needed anymore, and is causing new compatibility problems with other broken web servers, so let's get rid of it.

All reviewed patches have been landed.  Closing bug.
Comment 4 Michael Catanzaro 2017-05-16 10:29:08 PDT 
By the way, since this only fixes compatibility with extremely broken TLS servers, and since there is a significant risk of unexpected regressions with other broken servers, I would not recommend backporting this.
