5.5.0 - Zawgyi

5.5.0 / 2021年09月19日

Zawgyi (Burmese: ဇော်ဂျီ) is a semi-immortal human alchemist and mystic with supernatural powers and often seen with a magic stick and a red hat. Zawgyi is one of the supernatural figures in Burmese mythology and folklore. Name chosen by new (Myanma!) contributor @​ye-lin-aung.

The headline feature of this release is a new integration with the localhost gem. Localhost takes care of creating a self-signed SSL certificate for you in development. Require it in your config.ru:

# Sinatra
require './app'
require 'localhost/authority'
run Sinatra::Application
Rails
require 'localhost/authority' if Rails.env.development?
run MyRailsApp::Application

... and in the development environment, Puma will use a self-signed SSL cert generated by Localhost if no other cert is provided. Note: Make sure you set up Puma to run on an SSL socket: puma -b 'ssl://localhost:9292' config.ru
