October 2025 was focused on delivering user-centric features, stabilizing UI behavior, and advancing release readiness for ptx2pdf. Key features delivered include aligning Catalogue/TechRef viewer behavior, reworking UI borders for consistency, and UI/tabs refinements across Basic, Cover, and Styles areas. Major bugs fixed encompassed opening Ornaments Catalogue in the system viewer from modal dialogs and several UI stability issues, alongside fixes to editing behavior and project configuration states. The month also advanced release readiness with 2.9.9 release notes and release, plus groundwork for 3.0.x, including pre-release 3.0.0/3.0.1 and versioning adjustments. The Styles tab enhancements expanded font detail visibility, search/filter capabilities, and twisties display. Overall, these changes improve workflow reliability, reduce user friction, and strengthen the product’s maintainability and release discipline.
