H2O version 2.0.3 / 2.1.0-beta2 released

I am happy to announce the release of H2O HTTP/2 server version 2.0.3 and 2.1.0-beta2.

Version 2.0.3 is a maintenance release fixing issues found since the release of 2.0.2.

Version 2.1.0-beta2 introduces many features in addition to those introduced in 2.1.0-beta1, including mruby-based DSL for access control and DoS mitigation.

Please let us know if you find any issues in the beta release. We plan to release final version of 2.1.0 pretty soon.
