June 2026 monthly summary for ghostty-org/ghostty. Focused on accessibility, memory safety, and robust selection handling to deliver reliable, accessible user interactions and reduce support risk. Key work consolidated selection state changes, improved screen reader synchronization, and strengthened stability across input paths. What changed: - Implemented a unified selection_changed notification path with a debounced macOS Accessibility signal, ensuring the active selection is accurately announced without latency or stale reads. Cross-platform groundwork prepared; GTK remains a no-op until a consumer is present. - Added automated tests to verify that selecting new pins frees previously selected pins, preventing memory leaks and ensuring correct active selection tracking. - Fixed a use-after-free in the selection flow by removing an optimization that read freed memory; ensured safe, correct copying of selection data and stable behavior across input events. - Consolidated selection state changes to route through setSelection, with the new setSelectionAndCopy extension adding copy_on_select semantics for consistent behavior across mouse and keyboard interactions and clipboard timing. Impact: - Improves accessibility accuracy and responsiveness for screen readers, reducing user-perceived latency and stale content. - Increases stability and memory safety, mitigating crash and leak risks during selection gestures. - Creates a clearer, single path for selection state updates, simplifying future enhancements and maintenance. Technologies/skills demonstrated: - Accessibility integration on macOS (NSAccessibility signals, debouncing) - Memory safety and use-after-free remediation in C-like code paths - Test-driven validation for resource lifecycle in selection handling - Cross-input-path coordination and state management
