* Improved reliability by preventing crashes or hangs during handwriting recognition, page thumbnails, the study navigator, Library Search indexing, and large text-selection changes. * Better protection for your work: fixed sync cases where unshared documents stayed visible, local unsynced work could be removed after certain sync errors, and web audio recordings only appeared after reopening a document. * Fixed several image rendering issues where cached images, imported images, embedded thumbnail images, or updated child images could disappear or appear invisible. * Improved exported and previewed content: highlighter colors on dark paper now look correct, cropped screenshots stay cropped, and highlighter or tape content moves with handwriting during whiteboard reflow. * Fixed several toolbar and picker issues, including hidden bottom toolbars, inconsistent button colors, clipped eraser/font/line-height settings, missing Font back buttons, and popovers shifting when the keyboard is visible. * Improved navigation and window-layout polish, including tab bar gaps after leaving Split View, inconsistent back buttons, compact account-menu animation, Settings menu widths, and clipped dropdown values. * Improved text editing reliability: Enter works after IME composition on iPad, text document menus stay accessible in tight spaces, and text inside shapes no longer jumps when selected. * Fixed link, search, and sharing controls: clearing search no longer returns you to the Library, Remove Link stays visible above the keyboard, and unavailable sharing toggles no longer snap back abruptly. * Fixed visual issues in panels and popovers, including empty bookmarks overlapping headers, template metadata corners, iPhone document-action borders, outline modal backgrounds, transparent audio-list popovers, and the Mac inspiration gallery layout. * Education: Improved audio, study, and class flows: transcription highlighting continues until playback ends, duplicate Class Folders are prevented, and Practice study sets stay visible after a back-swipe gesture. * Fixed drawing and connector behavior: connector endpoints snap correctly, deleted elbow waypoints stay deleted, erasing unaffected content no longer changes Undo or Redo, and handwriting selection/reflow borders behave correctly. * Fixed an issue where calendar integration could appear signed out after restarting the app. * Image and media captions in text documents now work correctly with undo and redo. * Copying a video block from a text document into a Notebook now copies only the video URL. * General bug fixes and stability improvements.
