v1.5

New Features

• Screen Annotation — Draw directly on your screen during recordings. 9 tools: Pen, Highlighter, Arrow, Line, Rectangle, Ellipse, Text, Eraser, and Laser Pointer (fades after 2s). Floating toolbar with keyboard shortcuts, 5-color palette, line width slider, undo/redo, and a record overlay toggle. Whiteboard mode (press W) gives you a clean canvas with 4 background patterns (Blank, Dots, Grid, Lines). Works across multiple displays and during active recordings via ScreenCaptureKit
• Cursor Highlight — A visual highlight follows your cursor during recordings and presentations. 4 shapes: Ring, Filled, Squircle, and Rhombus. Click animations for left click (scale) and right click (flash). Customizable size, color, opacity, and border width in Settings > Presentation
• Spotlight — A dim overlay covers the screen with a bright circular cutout following your cursor to focus viewer attention. Adjustable size, dim intensity, edge softness, and follow speed (Instant or Smooth). Works across multiple displays
• Menu Bar Status Item — New menu bar icon with recording state indicators (idle, recording, paused, countdown) and elapsed time. Dropdown menu for Start/Pause/Resume/Stop Recording, Show Lumary, and Quit
• Teleprompter Hotkeys — New global hotkeys for Play/Pause, Reset to Top, Speed Up, and Speed Down (configurable in Settings > Shortcuts)
• Presentation Tools Integration — Cursor Highlight and Spotlight buttons in the main toolbar, global hotkeys, URL scheme commands (lumary://toggle-cursor-highlight, lumary://toggle-spotlight), and Stream Deck plugin support

Improvements

• Metal Composite Rendering — Composite mode now uses a custom Metal compute shader instead of CoreImage, eliminating per-frame CIFilter graph rebuilds. SDF-based shape rendering with anti-aliased edges, separable Gaussian blur for shadows, and zero-copy IOSurface sharing between recording and preview
• Standard Mode Performance — Preview frames wrapped as Metal textures via CVMetalTextureCache (no GPU-to-CPU readback). Three separate timers consolidated into a single 30Hz timer with ~15ms/sec CPU savings
• Non-Blocking File Writing — FileSink.append() now dispatches writes asynchronously, removing usleep retry loops that could stall frame delivery by up to 2.5ms per frame
• Auto-transcription now skips sessions with no microphone source
• Fixed transcription spinner stuck indefinitely when transcription fails
• Settings Shortcuts section reorganized into groups: Recording, Teleprompter, Annotation, Presentation
• Removed 10fps preview cap during recording — preview runs at full framerate

Bug Fixes

• Fixed tooltips disappearing quickly across the entire app — now uses AppKit's native NSView.toolTip via NSViewRepresentable
• Fixed potential crash from force unwraps in AnnotationOverlayView and ScreenSource
• Fixed NotificationCenter observer leak in SessionsWindow/CoursesWindow on repeated open/close
• Fixed AVCaptureSession.commitConfiguration() not guaranteed on error paths
• Fixed potential deadlock in camera/video-source wait-for-ready continuations
• Fixed folder directory creation errors being silently discarded
