June 2026 (2026-06) monthly summary for ladybirdbrowser/ladybird focused on stability and correctness improvements across core subsystems. Delivered critical bug fixes in rendering, DNS parsing, and WebAssembly validation, with clear impact on user experience and reliability. Key outcomes include preventing crashes in SVG coordinate parsing, hardening DNS label handling against invalid inputs, and guarding WebAssembly module validation against out-of-range indices. Added tests to validate LibWasm type index handling, reinforcing long-term stability. Technologies demonstrated include C++, LibWeb/SVG, LibDNS, and LibWasm, with improved error handling, test coverage, and cross-component collaboration.

May 2025: Nextcloud Desktop delivered HSTS-based SSL error handling to reduce unnecessary security prompts. The feature parses and applies HTTP Strict Transport Security hints to suppress the 'Cannot connect securely' dialog when the HSTS policy is valid and not expired. On first connection, HSTS status is cached via QNetworkAccessManager; on subsequent connections, if a server presents an invalid certificate but an valid HSTS hint exists, the connection will fail early, avoiding confusing prompts. Implemented by enabling enableStrictTransportSecurityStore and setStrictTransportSecurityEnabled in the AccessManager-provided QNetworkAccessManager. Commit: 6ee12311485745cb92fd022ef328f9010bf6a773.
