Sep 1, 2025September 2025 (Month: 2025-09) focused on UX refinements for mpv's command-line and menu interfaces, delivering precise enhancements to reduce user errors and improve readability. Key features include Smart Console Completion Refinement, which prevents unintended autocompletion when partially typed, and Menu Spacing Improvements with configurability to tailor item gaps and line height for console and context menus. The latter introduced a configurable gap (gap script-opt) and a font-size-aware gap for context menus, improving readability across font sizes.

Jul 1, 2025July 2025 — mpv-player/mpv: Delivered user-facing configuration editing UI, a bug fix for path normalization, and documentation enhancements. These changes improve configurability, correctness, and developer-facing clarity, while reducing support overhead and aligning docs with behavior. Key outcomes: - In-app UI for configuration editing and docs access: UI bindings to edit mpv.conf and input.conf from the application menu, creation of missing config files as needed, and opening them in the system editor; added a menu entry to open online documentation. Commits: 7c1a4acdb24b2be82b9cb9bbfd3d7bc55bf17e70; f147b133f0a06dd98baeb0b1cd3d08bacc346260. - Normalize stream-open-filename and fix documentation claim: Fixed normalization by applying mp_normalize_path before returning; corrected docs that claimed it was already normalized. Commit: b47fd2842a295fca9d7681a7a85a8371faad0c47. - Documentation improvements: Key binding clarity and file path references; clarified multi-key sequence matching/overrides and corrected PATHS → FILES typo where appropriate.

Mar 1, 2025March 2025 monthly summary for mpv-player/mpv: A focused sprint delivering stability, UX enhancements, and scripting flexibility. The month encompassed 11 commits across Lua code, commands, and docs, with notable work on console scripting reliability, user preferences, and UI alignment. Key UX and feature deliveries include remembering input between sessions, centering the console within OSD margins, adding a monospace font option, showing chapters when the first chapter appears after playback, and expanding the type command handler to accept variadic arguments. Critical stability fixes addressed crashes in console script handling and selection mode, plus safeguards against verbose logging recursion. These changes reduce user friction, improve customization, and strengthen the console subsystem. Tech stack highlights include Lua scripting, script-opt integration, and codebase standards (double quotes) and docs formatting for consistency.
