January 2025 monthly summary for keymanapp/keyman. Delivered centralized Sentry logging via KMSentryHelper with detailed breadcrumbs and architecture-specific tags, wired across input method lifecycle and UI actions, introduced test build support and logging refactors to improve error reporting and analytics. Improved macOS Keyman lifecycle handling for robust debugging and resilience when contexts change. Fixed On-Screen Keyboard activation when a KVK is missing and ensured OSK visibility adheres to activation settings. Corrected architecture tag logic to default to Unknown for unrecognized processor types, improving robustness of issue categorization. These efforts enhance observability, reliability, and developer experience, enabling faster triage, better analytics, and more predictable user experiences on macOS.

December 2024 (2024-12) monthly summary for keymanapp/keyman: Key features delivered: - macOS About box UI polish: updated SIL logo to include Andika glyph and corrected three-color stripe rendering for branding fidelity and a more polished user experience. - iOS keyboard height handling foundation: introduced a new constant unknownDeviceKeyboardHeight to gracefully handle unknown device keyboard heights, establishing groundwork for stable height calculations; plus groundwork for improved keyboard height logging and layout stability. - Cross-platform maintenance and readability improvements: targeted refactoring and enhanced logging to improve maintainability and troubleshooting for future releases. Major bugs fixed: - iOS keyboard handling and layout stability: fixes around keyboard height changes, orientation handling, layout updates, and asynchronous layout to stabilize iOS keyboard interactions across rotations and transitions. - macOS KMX data loading reliability: refactored to pass KMX data blob to Keyman core instead of a file path and added error handling when KMX data cannot be read. - OSK and keyboard modifier synchronization: ensured OSK modifiers stay in sync with the physical keyboard and reset modifiers when the OSK window closes to prevent stray states. - Mac internal maintenance and refactoring: split up timerAction, rename log statements, and perform general refactoring for clarity to reduce future regression risk. Overall impact and accomplishments: - Significant improvement in keyboard input stability and user experience on iOS and macOS, with reduced layout glitches and fewer data-read failures. - Branding and UI polish enhanced on macOS, contributing to a more cohesive and professional product appearance. - Improved data reliability for KMX assets through blob-based data handling and explicit error reporting. - Strengthened code quality and future maintainability via targeted refactoring and enhanced logging. Technologies/skills demonstrated: - Cross-platform development (iOS/macOS), including keyboard handling, OSK integration, and layout management. - Keyman core data handling with KMX blob usage and robust error handling. - UI polish, asynchronous layout considerations, constraint management, and comprehensive logging. - Branding fidelity and accessibility-conscious UI improvement.
