Release notes

This release includes new features and improvements.

  • Adds a new run mode for web apps. This mode allows accessing web apps from the client browser directly instead of interacting with a browser running on the server. This will drastically reduce the server resources used by this type of app.
  • Adds support for JSON-RPC. The server detects if the request is XML-RPC or JSON-RPC and responds appropriately. This feature allows using the server with older clients (Moodle VPL plugin version < 4.0.0) and new clients that run on PHP 8 or higher without XML-RPC support. Using JSON-RPC also removes the limits of XML-RPC ints.
  • Adds a new RPC call named “update”. This RPC call allows updating files in the execution environment from the client without stopping the executing task. This call is useful for interpreted languages such as PHP in a web app.
  • Adds a new RPC call named “directrun”. This RPC call will allow new future features.
  • The WebSocket protocol is improved to accept larges packets and fragmented packets.
  • Adds SSL_CIPHER_SUITES configuration parameter. This parameter is used to set ciphers for TLSv1.3 if available.
  • Adds HSTS_MAX_AGE configuration parameter. This parameter allows HTTP Strict-Transport-Security by setting the max-age parameter of the Strict-Transport-Security header. This parameter requires the use of PORT = 0.
  • The installer adds Julia programming language to the list of development software installable.
