- Fix crashes when /proc is not available in the chroot (bsc#947458)
- Correctly parse GSSAPI KEX algorithms (bsc#961368)
- More verbose FIPS mode/CC related documentation in README.FIPS (bsc#965576, bsc#960414)
- Fix PRNG re-seeding (bsc#960414, bsc#729190)
- Disable DH parameters under 2048 bits by default and allow lowering the limit back to the RFC 4419 specified minimum through an option (bsc#932483, bsc#948902)");
