Aug 1, 2025August 2025 focused on performance, reliability, and maintainability across Geoviite. Major deliverables include: 1) version->object multifetch for layout assets with tests and review fixes; 2) stabilization of spatial referenceline/locationtrack queries through targeted cleanup and performance fixes; 3) publication asset base versions with non-null end-state to ensure consistent end-state handling; 4) relaxed node reconnection requirements on edge inner nodes to better support intermediate states in multi-switch linking; 5) progress on topology-based validations for track geometry (WIP). Additional code quality work included UI library upgrades, stricter geocoding types, Publication data class refactor with CSV handling improvements, and removal of streaming parseLines to simplify autoclose behavior.
