Language
- Significantly improved the way that dataflow errors and panics are handled in the interpreter. They now flow through the program in a far more seamless fashion, and panics are supported properly in the IDE without the whole program dying (#1433).
- Significantly improved the syntax and semantics for FFI with JVM languages, making it far more of a first-class citizen in Enso (#1443).
- Added support for polyglot JavaScript definitions to Enso (#1451). These allow users to write JavaScript inside Enso, and seamlessly call between Enso and JS code.
Interpreter/Runtime
- Fixed an issue where executing a host value could result in a
NullPointerExceptiondue to a missing null check (#1413). - Fixed an issue where dataflow analysis was incorrectly tracking usages of undefined variables. This resulted in problems for the runtime server (#1421).
Tooling
- Added support for collection of profiling information about the running program to the language server protocol (#1407). Initial support is for collection of execution-time information.
- Updated the default
mainin a new Enso project to be more IDE friendly (#1419). - Added support for panic sentinels in the runtime instrument, allowing the language server to trace the expressions affected by a panic while still executing others (#1436).
- Added support for checking the Enso version for a particular project in the project manager, allowing the IDE to improve compatibility with multiple versions (#1454).
Libraries
- Updated the way that we use dataflow errors in the standard libraries, making our
Basefunctionality much more amenable to working in the IDE (#1446).
