July 2025 performance snapshot: Delivered a broad set of features and reliability improvements across tiptap-docs and tiptap, with a strong emphasis on developer experience, documentation quality, and scalable packaging. In tiptap-docs, implemented Pages extension enhancements with demos integrated in the docs, refined API and documentation consistency, and tightened UI layout by hiding secondary sidebars for larger page formats. Completed a migration to the alpha package version (update of import paths and package name via tag), and refreshed installation/docs flows with naming changes and back- sidebar removal where appropriate. Expanded demo pipelines by switching pages demos to the new source, added restricted tags to guides, and enhanced docx export documentation (headers/footers and page size) plus licensing callouts. Fixed a key packaging usage bug and improved browser robustness in the Firefox demo by ensuring safe boolean handling. In tiptap, resolved Firefox rendering and editor state reliability issues by introducing nullish checks and safe defaults. These efforts collectively reduce onboarding friction, improve API discoverability, and increase maintainability for future iterations.
