H2O version 2.3.0-beta1 released, improvements presented at Rubykaigi 2018

Today, I am happy to announce the release of H2O version 2.3.0-beta1.

Version 2.3 is going to be the largest release in the history of H2O. Beta-1 already includes more than 50 changes contributed by more than 10 developers.

Improvements include:
  • more powerful mruby handler with Rack and Rack middleware support
  • load balancing in the reverse proxy handler (#1277, #1361)
  • more flexible configuration through the use of !env and stash directives (#1524, 1739)
  • support for new and upcoming HTTP extensions: Server-Timing (#1646, #1717), 103 Early Hints (#1727, #1767), 425 Too Early (#1344)

The improvements related to mruby and HTTP extensions were covered in today's our talk at RubyKaigi 2018 and the slides are below. Please enjoy!
