• Added syntax for interleaved connections (#416)
• Created a new Rust target (#488, #628)

Platform support

• LF programs with the TypeScript target can now be compiled on Windows (#850).
• Added Windows support for the C and Python targets (#532)

Runtime

• Implemented the Savina benchmark suite in the C, C++, and Rust target (modulo those that require mutations)
• Improved performance of the C++ runtime considerably

Python

• Multiports and banks are now iterable in the Python target (#713)
• Fixed an issue where top-level custom Python classes were being serialized incorrectly

  that can be passed down the reactor hierarchy via parameter assignment.

Tool support

• Created an Language and Diagram Server that enables our new VS Code extension

VS Code extension

• Generated code is now validated when an LF file is saved for all targets except C (#828). Generated C code is only validated when it is fully compiled.

Utilities

• Added tools for exporting dependency information from the C++ runtime (#788)
