TinyGo 0.42 Adds Recoverable Panics, UEFI Support; Releases Starter Kit
Key points
- TinyGo 0.42 introduces recoverable runtime panics.
- New UEFI target allows Go code to run before OS boot.
- TinyGo 0.42 supports Go 1.27 and LLVM 22.
- TinyGo Starter Kit with Seeed Studio XIAO was released.
TinyGo 0.42 Software Updates
TinyGo released version 0.42, which includes significant software updates. A key feature is the introduction of recoverable runtime panics, allowing developers to catch errors like nil pointer dereferences and out-of-bounds accesses using standard defer and recover constructs. This brings TinyGo closer to standard Go's error handling capabilities.
The new release also adds a UEFI target, enabling Go code to execute natively as a UEFI application before an operating system boots. TinyGo 0.42 supports Go 1.27 and LLVM 22, ensuring compatibility with recent language and compiler versions.
Previous Version Enhancements
These software advancements follow TinyGo 0.41, which focused on native wireless capabilities and cross-environment execution. Version 0.41 expanded native Wi-Fi and Bluetooth networking for ESP32-C3 and ESP32-S3 chips via the espradio library and simplified device deployment with espflasher. It also added support for hybrid boards like the Arduino UNO Q.
WebAssembly and WASI Capabilities
TinyGo continues to support serverless, edge, and browser environments by compiling Go into WebAssembly (.wasm) and WebAssembly System Interface (WASI) binaries. Leveraging Binaryen's Asyncify, TinyGo supports standard Go goroutines within WebAssembly runtimes. The ecosystem demonstrated its advanced Wasm and reflection performance by compiling typescript-go, Microsoft's TypeScript compiler written in Go, entirely into WebAssembly.
New Hardware Starter Kit
In addition to software updates, TinyGo announced the TinyGo Starter Kit with Seeed Studio XIAO. This kit was developed in partnership with Seeed Studio and provides a hardware bundle for developers.
