    • ➕ Added route GET /languages/:id for getting all attributes of specified language.
    • ➕ Added route GET /languages/all for getting a list of all languages (archived and active).
    • ➕ Added route DELETE /submissions/:token for deleting specified submission. Only authorized requests (users) are allowed to delete a submission.
    • Added configuration variable ENABLE_SUBMISSION_DELETE with default value set to false. By default you cannot delete a submission as long as this variable is set to false. When set to true then only authorized requests (users) can delete specific submission.
    • ➕ Added info routes GET /about, GET /version, GET /license and GET /isolate. Last route GET /isolate returns result from isolate --version command.

    👌 Improvements

    • 🚀 Updated base image to judge0/api-base:1.0.0 which uses Debian "buster" and has installed Ruby 2.7.0.
    • 👌 Improved handling of an server error when one or more submission attributes cannot be serialized to JSON without Base64 encoding. User now gets an error with instructions to use base64_encoded=true query parameter.

    🐛 Bug Fixes

    • 🛠 Fixed example in configuration for using ALLOW_ORIGIN variable with multiple origins.
    • Fixed a bug where value of MAX_MAX_PROCESSES_AND_OR_THREADS was used as default value for max_processes_and_or_threads attribute of submission, whereas MAX_PROCESSES_AND_OR_THREADS should be used.

    Other Changes

    • Increased maximum allowed compiler_options and command_line_arguments length to 512 characters.
    • 🖨 Increased default value of MAX_PROCESSES_AND_OR_THREADS to 60.
    • Increased default value of MAX_MAX_PROCESSES_AND_OR_THREADS to 120.
    • 🔄 Changed default value of RAILS_ENV to production.
    • 🔄 Changed default value of INTERVAL to 0.1.
    • ⚡️ Updated year in LICENSE.
    • Added environment variables JUDGE0_{HOMEPAGE,SOURCE_CODE,MAINTAINER,VERSION}. Isolate sandbox inherits these variables and they are now available for use in user code.
