How it got here

2018–2019 · Fyne v2 architecture and feature expansion

This period focused on the development of the Fyne v2 toolkit, introducing a comprehensive set of new UI components, layout managers, and rendering capabilities. Key additions included a hardware-accelerated OpenGL painter, accessibility support, and platform-specific features like system tray management and mobile device interaction. The release also standardized the internal architecture by removing abstract driver interfaces and bundling default assets.

31 changes

2020–2021 · Architecture modernization and platform expansion

This period focused on modernizing the codebase with Go generics and a modular CLI structure, while introducing a pluggable storage and rendering architecture. Significant efforts were made to support mobile platforms through OpenGL ES bindings, Android DEX generation, and accessibility integrations. The release also expanded the toolkit with new container types, validation utilities, and headless rendering capabilities.

26 changes

2022–2026 · Infrastructure and platform abstraction

This period focused on establishing a robust internal architecture, introducing internationalization, and enhancing platform integration through new driver interfaces and build configurations. The work also added core utility packages for scaling, scheduling, and geometric calculations to support future feature development.

About this page

  • The description of this project is derived from its own commit history, not from its README.
  • The score is its highest published measurement, taken on 1 August 2026 at a pinned commit. It is not a live figure and does not change until the project is measured again.
  • Measured at commit c8a24083d0 — the exact code this score is about.
  • Scored under rubric rubric-2026.08.18. Score the same commit under that rubric and you get the same number.
