In recent weeks, the team behind Zed has embarked on a significant overhaul of its UI framework, transitioning to GPUI2 to redefine the application's foundation before opening its source. This transformation is driven by the need to address the limitations of the previous GPUI version while preserving its strengths, and it emphasizes enhanced ergonomics and performance. GPUI2 introduces a single object, AppContext, to manage application state and employs a new model for handling documents and events, using Rust's type system to facilitate refactoring. Team members like Marshall and Mikayla have been deeply involved in implementing new systems, such as a theme system based on color scales, and integrating tailwind CSS-inspired styling helpers. Despite challenges posed by dependencies and remote work, the team's collaborative efforts, aided by Zed's synchronous programming capabilities, have made significant progress, with approximately half of the application rewritten. The team remains optimistic about releasing a preview soon and is actively seeking new members to join their mission of advancing software development.
