v1.4.0

• Added autocert: Integrated Let's Encrypt support activated and controlled by the following environment variables:
  • HTTPS_AUTOCERT_ENABLED: Set to true to enable autocert.
  • HTTPS_AUTOCERT_HOSTS: A comma-separated list of hostnames that autocert applies to. If not defined then applies to every host.
  • HTTPS_AUTOCERT_DIR_CACHE: A directory where Let's Encrypt data is cached. If not defined then the data is cached in memory.
• INFO_URI_TEMPLATE: RFC 6570-style URI template for fetching extra information to each trace hop.
