Changes since the previous USCE release

Changes compared with USDX 2026.9.0

This release adds 24-player layouts, editor score breakdowns, shared synth and
beat-click timing, and expanded playlist controls. Windows can be resized and
themes adapt to the screen aspect ratio, including 16:9 and 21:9.

🚨 Breaking changes

• Avatars, themes and plugins are detected in home and application directories. On Linux, highscore plugins are no longer loaded from the installation directory. 365f9be, 167e14f

• Remove the obsolete basic editor and MIDI-import screens. The full song editor remains available. #68

• Use the built-in synthesizer for all MIDI previews. System and external MIDI output through PortMidi are no longer available. #78

• Allow medleys for any song with playable notes, including duets and relative songs. Explicit medley ranges still take priority; the legacy CALCMEDLEY=Off switch no longer excludes a song. #64

• Remove rap and medley badges from song selection; video and duet indicators remain. #65

📈 Enhancements

• Keep fonts, images and avatars in proportion across screen aspect ratios. #83
• Use generic player layouts across player selection, duet selection, singing and scoring, with selectable player counts up to 24. #70, #71, #72, #76, #77
• Show statistics in aligned detail tables, with adjustable row counts, time ranges, score-count filters, library coverage and activity summaries. Choose a Reduced or Full presentation in Options > Game. #82, #109
• Suggest recently used player and team names while typing, with shared name-entry behavior across solo, party and tournament screens. #108
• Accelerate note shifting while holding the editor keys. #49
• Improve built-in MIDI synthesis and unify editor beat and MIDI preview timing. #78
• Add a remaining-score bar showing the score still achievable, with rating-only, remaining-only and combined display modes. #62
• Add playlist search, sorting, reordering and controls for adding or removing the displayed songs. Refresh active playlists when their files change. #61, #46
• Start song previews through one scheduler for mouse, keyboard and playlist navigation, deferring video startup until selection and screen transitions settle. #58
• Draw fewer oscilloscope points to reduce rendering work, while keeping audio analysis and scoring unchanged. #31
• Keep preview music running consistently across player selection and results, and toggle fullscreen video previews with V. #55, #29
• Let K cycle through full vocals, a saved partial vocals volume and instrumental playback when a partial volume is configured. #37
• Show the perfect-score split between normal notes, golden notes and line bonuses in the editor, and add absolute pitch diagnostics in recording options. #44, #59
• Search by several characters while holding Alt, with improved navigation out of song folders. #40
• Improve chained theme and skin inheritance, including shared assets, themed sounds and category covers. #81, #52, #54
• All themes from the USCE Themes repository are included in the downloads. #20
• Duets save highscores. This can be disabled in Options > Advanced. 255e3bd, 6798291

🪲 Bug Fixes
