Toit v2.0.0 — Toit blog
Not investment advice. Muhabbit scores how much a story may matter, not which way to trade.
Toit, the open-source programming language for embedded systems, has released version 2.0.0 after more than four years of alpha development involving 2,000+ commits, 500,000+ lines changed, and 200+ alpha releases. The language began as closed-source software at Toitware, which shut down in 2024, and has since been maintained by volunteer contributors. The v2.0.0 milestone follows a final breaking change—a refactoring allowing peripheral APIs to accept pin numbers directly rather than requiring gpio.Pin objects. Key improvements since open-sourcing include broader hardware support spanning Arm-based EC618 and nearly all ESP32 variants, a rewritten package manager, mixins, and firmware envelopes for customizing firmware without SDK rebuilds. The release signals community-driven sustainability for a language orphaned by its original company's closure. Upcoming work includes a code formatter, compiler resolution improvements, and support for additional architectures.
