* Bug fixes and stability improvements.
Build 883592969v1.25.12026-03-24 21:35:53
New:
• Garmin Pilot (GPLT) format — Import and export checklists directly compatible with the Garmin Pilot™ app. Full round-trip support preserves your checklist structure, sections, and items.
Build 883039810v1.25.02026-03-20 16:06:43
- Improved Purchase Experience — Redesigned purchase history and streamlined paywall. Subscription status is now reflected instantly throughout the app.
- Live Fly Mode Fix — Resolved an issue where Live Fly mode could be inaccessible after a sync or export operation.
- Reliability Improvements — Fixed edge cases in checklist export timing and iCloud sync gates to ensure your data is always ready before sharing.
- Performance & Stability — Under-the-hood code quality improvements for faster, more reliable operation.
Build 882929552v1.24.02026-03-04 07:55:18
Fly Mode — Run your checklists hands-free in the cockpit.
- Sequential item runner with progress tracking and elapsed timer
- Voice callouts read checklist items aloud with automatic best-quality voice selection
- Auto-advance mode progresses through items hands-free when voice is enabled
- Challenge-response reveal mode (optional) — tap to reveal the response
- Configurable run options in the pre-flight setup sheet
Other Improvements
- Checklists now support group categories (Normal, Abnormal, Emergency) with color-coded icons for better ForeFlight interop
- Performance and stability improvements
Build 882627376v1.22.02026-02-23 09:59:59
- Export checklists as professionally styled PDF documents with multiple template options — save, share, or print directly from the app

- Dynamic Type support — icons and UI elements scale with your preferred text size
- Respects Reduce Motion and Increased Contrast accessibility settings
- Smoother, faster checklist editing experience with rebuilt editor architecture
- Visual feedback when opening share and print so the app never appears frozen
Build 882455739v1.21.12026-02-14 21:25:36
New Features
- New export formats: AFS, GRT, MSFS, XChecklist, and RTF — import and export checklists in more industry-standard formats
- macOS support preparation
Bug Fixes
- Fixed fullscreen checklist preview hiding under the Dynamic Island — now truly edge-to-edge with overlay Done button positioned
inline with the camera cutout
- Fixed presenting page's navigation bar changing color when opening checklist preview
- Removed duplicate checkmarks in all sort-by menus (SwiftUI Picker already renders its own)
- Fixed fake sync completion notification firing before actual sync finished
- Fixed potential data races in NSItemProvider drag-and-drop callbacks (extracted Sendable values before Task boundaries)
- Fixed race condition where subscription accumulation could occur when SwiftUI calls onAppear multiple times
- Fixed suppression timer leak in FileSyncMonitor (new subscriptions accumulated without cancelling old ones)
- Fixed dead Combine chain in FileSyncMonitor (scan/map/removeDuplicates assigned to _, doing nothing)
- Removed redundant DispatchQueue.main.async wrappers inside @MainActor classes
- Fixed double file parsing in PremiumTemplate.fromFile (same ACE file was read and parsed twice)
- Merged duplicate .onAppear blocks in MainTabView iOS branch
Performance & Memory
- Introduced DownsampledImageView for photo gallery — decodes images at screen size via ImageIO instead of full-resolution
UIImage(data:), significantly reducing memory usage
- Added file size validation in import service to prevent out-of-memory errors with very large files
- Added memory warning handler for OCR workflow with [weak self] in progress closures to prevent retention after view dismissal
- Replaced all DispatchQueue.main.async/asyncAfter with Swift 6 structured concurrency (Task { @MainActor in })
Stability & Crash Prevention
- SwiftData corruption no longer crashes the app — falls back to in-memory store so the user can still see UI and report the issue
- Removed all force unwraps (as!) and force-try across the codebase
- Added safeSave method on ModelContext with error logging
- Changed delete rules to .nullify for audit/compliance records (prevents data loss)
Code Quality
- Removed CockpitModeManager — no longer needed after switching to overlay-only fullscreen preview layout
- Centralized notification names as Notification.Name constants (replaced 6+ scattered raw strings)
- Replaced all print() calls with structured logDebug/logInfo/logWarning/logError via AsyncLogger
- Removed dead/deprecated code: unused properties (photoIdentifiers, needsSoftwareUpdate), unreachable DriveMonitor block
- Added regression test suite: sync correctness, notification names, drive connection events
Build 882432508v1.19.02026-02-13 19:45:16
- Fixed: Exporting checklists with slashes in the title (e.g., "Bonanza Operating Checklists 1/16/26") no longer fails with "26.gcl does not exist" error (#55)
- New String.sanitizedFilename API — robust, single-pass filename sanitizer handling FAT32/iOS/macOS illegal characters, control characters, length limits, and Unicode
- Fixed Swift 6 compile error in GPLTSBinaryAnalyzer (withUnsafeMutableBufferPointer)
- 50 new filename sanitization tests (illegal chars, consecutive collapse, control chars, edge cases, Unicode/emoji, length caps, write-to-disk integration)
- 5 new FMD tests
