Version 1.10-RC1 Highlights

  • TLS versions 1.0, 1.1, and 1.3 are now always enabled in addition to the previously default 1.2. It will be up to a client which version to negotiate. Nowadays TLS 1.0 and 1.1 are considered insecure but there are still API servers that support them and clients that don’t “speak” 1.2 or 1.3.
  • Fix for a problem with the “not equals” matching operation.
