What's New in This Version Liquun 2.0 turns the original research notebook into a more complete personal research workflow. • A new experiment workflow connects objectives, hypotheses, protocol snapshots, timepoints, structured results, conclusions, and next steps. • Link local files or folders to experiments and retain paths, modification times, sizes, and SHA-256 fingerprints without copying or uploading the original data. • The new Lab Knowledge Hub keeps people, equipment, reagent locations, and working protocols findable. • A redesigned research desk brings overdue tasks, pending timepoints, active experiments, unread papers, key findings, and upcoming meetings together. • Tasks and meetings now retain their project, experiment, and discussion context, making it easier to turn feedback into action. • Command-K global search finds records across the entire workspace. • Full Chinese localization with quick switching between English and Chinese. • Improved local backups, export, restore, and database migration protection. • Better macOS menus, keyboard shortcuts, and window reopening behavior. • A redesigned app icon with clearer recognition at Dock and small sizes. All research records remain on your Mac by default.
