Toit v2.0.0

# Toit v2.0.0 — Toit blog Source: [https://toit.io/blog/toit-v2-0-0/](https://toit.io/blog/toit-v2-0-0/) After more than four years of alpha development, 2,000\+ commits, 500,000\+ lines changed, and 200\+ alpha releases, Toit[v2\.0\.0](https://github.com/toitlang/toit/releases/tag/v2.0.0)is finally here\. Toit began as closed\-source software developed by Toitware\. It later became an open\-source project, and volunteers have continued improving it even after Toitware shut down in 2024\. Despite the "alpha" label, Toit has been stable for a long time\. Two things kept us from calling it v2\.0\.0: we still had some breaking changes planned, and there was always another important feature we wanted to include\. Recently, we landed a refactoring that lets peripheral APIs accept pin numbers directly instead of requiring`gpio\.Pin`objects\. That was the last major breaking change on our list for v2\.0\.0\. As for waiting until all the important features are finished: we have accepted that this moment will never come\. Even now, there are open PRs for a formatter, compiler resolution improvements, and support for more architectures, among other major features\. Those will follow in future releases\. Here are a few highlights since Toit was open\-sourced: - Broader hardware support, including the Arm\-based EC618 and almost all ESP32 variants\. - A unified`toit`command and improvements that make Toit a more capable desktop scripting language\. - A rewritten package manager and a growing package ecosystem\. - Mixins for sharing implementations across classes\. - Firmware envelopes, allowing users to customize their firmware without rebuilding the SDK\. - Compiler and runtime improvements\. - Significantly better hardware testing\. - Syntax highlighting for Toit on GitHub\. Enjoy\!
