What happened
Audacity 4.0 rebuilds the entire UI on Qt with native high-DPI rendering, replaces the old Select/Envelope/Draw/Multi-tool modes with context-sensitive interactions, and introduces a new clip-editing model where clips can be directly selected, grouped, moved freely between mono/stereo tracks, and overlapped. Sync-Lock has been removed; splitting now uses a dedicated tool (hold S). Workspaces (Modern, Classic, Music) and light/dark/high-contrast themes are new.
Why it matters
If you use Audacity in any pipeline (podcasts, audio datasets for ML, demo recordings), expect to relearn key workflows—tool modes are gone, clip handling is fundamentally different, and some controls have moved. No action needed if you don't use Audacity.
Discussion angle
The Qt rebuild is a notable engineering decision for a long-running open-source desktop project—worth a quick note on migration strategy when a major framework swap forces breaking UX changes.
