July 2025: Stabilized the metadata batch editing flow in langgenius/dify by delivering a critical bug fix for cross-page document selections. Selections now clear when the search query changes and all selected IDs are correctly passed to the batch edit backend, addressing issue #23000 (commit 665fcad6551dfa0f95709692b05db927b98071bf). This improvement reduces the risk of incorrect batch edits and enhances data integrity, resulting in a smoother user experience.
