October 2025 monthly summary focusing on improving docs UX, pricing clarity, and maintainability across ASFHyP3/hyp3-docs and hyp3 repositories. Key features delivered include branding/navigation overhaul of the Hyp3 docs site with logos, home page updates, and a dedicated About section integrated via asf_theme; introduction of Hyp3+ intro and pricing changes (HyP3 Free to HyP3 Basic, credits expiration, and a revised usage/credits comparison); centralization of application language configuration by moving it to a snippet; and enhancements to usage guidance and credits documentation (move hyp3+ usage to guide; add cost). Supporting work included documentation hygiene (filename spacing, changelog maintenance), stability fixes (branding asset links), and quality assurances (UI fixes for footer map rendering and stray X element visibility). In addition, we rolled back an unintended deployment change, removed NASA tophat, and expanded HyP3 family support. The Hyp3 project also updated the Tibet-JPL throughput changelog to reflect improvements for operators. The overall result is a more maintainable docs platform, clearer pricing for users, and reduced maintenance overhead with centralized configuration and stable assets.
