Enso 0.2.1 (2021-01-15)

Language

• Removed Uniform Function Call Syntax, making the language much more predictable and allowing the compiler to provide improved diagnostics for common mistakes.

Interpreter/Runtime

• Return correct qualified names for modules at runtime, ensuring that the compiler and interpreter agree.

Tooling

• Improve the handling of bundled components with the Project Manager, ensuring rapid startup and easy integration with the IDE.
• Fixed the reflection configuration for the Project Manager, fixing a bug where it was unable to extract archives on Windows.
• The Language Server now uses qualified names in its messages, fixing a class of bugs where the IDE and Tooling did not agree on what a given expression was.
• Fixed mis-handling of tags in the documentation parsing infrastructure.

Libraries

• Implemented a stub file for the functionality built into the interpreter. This allows us to provide comprehensive documentation about this functionality for display in the IDE and for reading by library users.
• Added aggregation functionality to the Table library, allowing users to group their data.

Known Issues

• This is a beta release, so please see the issue tracker for issues opened before the release date.
