Nexen v1.4.30 brings UI stability fixes, TAS editor improvements, recording UX enhancements, additional performance optimizations, and code quality improvements.

Fixed

• Menu crash: Debug → Event Viewer — Event Viewer window initialization could fail because a required control field was null during XAML-backed control setup; switched the grid control to x:Name and hardened constructor lookup to resolve controls by name before creating the ViewModel (#1245)
• Menu crash: Tools → TAS Editor → Open/Create New Movie/Record — TAS Editor window initialization could throw NullReferenceException during control wiring when named controls were not initialized as expected; switched key controls (SearchBox, FrameList, PianoRoll) to x:Name for reliable code-behind binding (#1245)
• TAS Editor fire-and-forget async — LoadTasMovieAsync was called with _ = (fire-and-forget), masking potential exceptions; replaced with proper await (#1263)
• Recent Files menu disabled when empty — File → Recent Files submenu was disabled when no recent files existed; made it always enabled with an "(empty)" placeholder item (#1264)
• Event subscription leaks — AssemblerWindow and PaletteViewerWindow now properly unsubscribe from events in OnClosing to prevent memory leaks (#1235)

Changed

• Recent Play retention expanded — Increased rolling Recent Play checkpoint capacity from 12 to 36 slots (5-minute cadence, about 3 hours of history) (#1241)
• Auto Save behavior upgraded to persistent log — Auto Saves now use timestamped _auto_ filenames and are no longer single-file overwrite snapshots; save list origin detection supports both legacy and new naming patterns (#1241)
• Debugger close path hardening — Moved final debugger workspace save/release work off the UI thread and resumed execution before debugger release to reduce close-path deadlock risk when closing the last debugger window (#1242)
• TAS Editor improvements — ReactiveUI [Reactive] property generation, piano roll button label caching, bare catch elimination, async void safety, undo stack optimization (#1250–#1258)
• Bare catch elimination (phases 6–8) — Replaced bare catch / catch { } blocks across UI with typed catch (Exception ex) + Debug.WriteLine for diagnosability (#1260–#1262)
• Box-style action notifications — Tools menu actions (audio/video recording, screenshot, export) now display as centered box-style OSD notifications instead of bottom-left text; simplified message text removes file paths (#1264)
• Recording filename timestamps — Sound and video recorder default filenames now include yyyy-MM-dd_HH-mm-ss timestamps to prevent silent overwrites of previous recordings (#1265)
• GitHub Actions metadata — Added missing description properties to setup-ccache-action and build-sha1-action composite actions

Performance

• HexEditor per-frame allocation removed — HexEditorDataProvider.Prepare() called .ToArray() on every frame to produce a byte array from an existing byte array; eliminated the redundant copy (#1263)
• BreakpointManager LINQ → manual loop — GetMatchingBreakpoint() replaced LINQ .FirstOrDefault() with a manual foreach loop on the hot path (#1263)
