    🔄 Changed

    • ✂ Remove deprecation of Opal::Environment after popular request
    • Setting Opal::Config.dynamic_require_severity will no longer affect Opal.dynamic_require_severity which now needs to be explicitly set if it differs from the default value of "warning" (See also the Opal.dynamic_require_severity rename below).
    • The new default for Opal::Config.dynamic_require_severity is now :warning
    • Opal.dynamic_require_severity and OPAL_CONFIG are now merged into Opal.config.missing_require_severity (defaults to error, the expected ruby behavior) and Opal.config.unsupported_features_severity (defaults to warning, e.g. a one-time heads up that freezing isn't supported). Added variable __OPAL_COMPILER_CONFIG__ that contains compiler options that may be used in runtime.
    • Hash instances should now list the string map ($$smap) as the first key, making debugging easier (most hashes will just have keys there).
    • 🖐 Handle Pathname object in Pathname constructor

    🗄 Deprecated

    • Opal::Processor.stubbed_files and Opal::Processor.stub_file in favor of Opal::Config.stubbed_files

    ✂ Removed

    • ✂ Removed the previously deprecated Opal::Fragment#to_code

    • 💎 File::dirname and File::basename are now Rubyspec compliant
