Nov 1, 2025November 2025: Delivered key features and stability improvements across the Zed editor, driving developer productivity and code quality. Highlights include: - Inlay Hints stability and UX improvements: stabilized inlay hints queries, added tooltips for inlay label parts, and ensured proper chunking for the visible range to reduce flicker and duplication with multiple editors. - Outline panel navigation and scroll restoration: fixed search ranges for outline rendering, ensured scroll position is preserved, and refreshed outline on file renames for accurate navigation. - Diagnostics and LSP robustness: do not pull diagnostics when disabled, tone down extension errors, and skip buffer registration when LSP data should be ignored, reducing noise and improving stability. - UI polish and task UX: Show modal on hover for one-off tasks and improve focus behavior for the first window open; added rainbow brackets for better code readability. - Language server reliability and security: deduplicated inlays from multiple language servers, kept a single default PHP language server to reduce config complexity, and redact environment variables in server info view; also upgraded protocol library (proto v0.2.3) to bring fixes and improvements. - Technical highlights: notable Rust/LSP/tree-sitter work, performance-conscious UI fixes, and improved release-note traceability across commits.
