Work History
October 2025
53 Commits • 12 Features
Oct 1, 2025October 2025: Consolidated stability, privacy, and UI/UX improvements for telegramdesktop/tdesktop. Deliveries include: threading UI enhancements, folder actions from recent/top peers, privacy hardening (link hiding in groups and spam reports), and UI polish (correct direct userpic, removal of NEW badge). Also significantly improved macOS stability by avoiding forced OpenGL for the main window, and strengthened cross-platform build reliability (Windows, Xcode, GCC). OpenGL surface renderer interface simplification and screen share controls enablement contributed to maintainability and feature readiness. Versioning and submodule updates align with 6.2.x release cadence. These changes reduce crash surfaces, improve privacy and usability, and accelerate future feature work.
