September 2025 monthly summary for wireapp repositories focusing on reliability, security, and user experience improvements across web client products. The work delivered strengthened data integrity, cross-device UX, and robust error handling while advancing secure session management. Key achievements: - Emoji rendering stability (wire-webapp): Removed the old Android-specific hack for heart emoji generation and simplified Unicode handling, improving cross-device emoji rendering and consistency (#19476, WPB-4736). - Conversations data integrity and participant management (wire-webapp): Preserved participants on shell updates to avoid “Name Not Found” after connection requests; removed deleted users from all affected conversations and groups (#19451, WPB-19630; #19487, WPB-19791). - Security hardening and logout robustness (wire-webapp): Prevented reuse of cryptographic material; updated dependencies; hardened logout flow to handle client removal, flush typing indicators, and signout reasons (#19539). - User experience improvement: auto-focus for login (wire-webapp): Introduced useAutoFocus hook to auto-focus the password field when an email is pre-filled and locked, improving login UX (#19452, WPB-17650). - Backend error handling and local deletion robustness (wire-web-packages): Refactored BackendErrorMapper to use handler functions with fallbacks for unknown errors and made deleteLocalClient safe when no client exists, ensuring only local state is deleted and preserving safety/return semantics (#7323, WPB-19061; #7347, WPB-19348).

August 2025 monthly summary focusing on onboarding improvements and authentication reliability. Delivered a Team signup flow routing update in wire-webapp to direct Create a Team to the new signup page and centralized signup URL for maintainability. Hardened authentication error handling in wire-web-packages by mapping invalid token errors to InvalidTokenError, fixing endless loading after password reset, and expanding error mappings; added/tested coverage to prevent regressions. Impact: smoother onboarding for team accounts and more reliable sign-in flows, reducing user friction and regression risk.
