v1.20.2

Patch Changes

• c245519: AI Assistant's ChatComposer shows each attached file uploading, then done, and keeps a file that's too large (maxSize) or of a type it doesn't accept as a chip that says why, instead of dropping it. upload uploads each file as it's attached, and Send waits until every one is done.
• 6a5f6c4: AI Assistant's ChatConversation lets people edit a question in place and keeps the earlier version when they edit or regenerate, with buttons to step between versions under each question and reply. useChatStream keeps the versions, and AIChat takes versions and selectVersion for a chat that stores its own. sendMessage takes the messageId of the question an edit replaces, as the AI SDK's does.
• fbc253c: Kanban: a column can show an icon before its title, onMove can return false to refuse a move (the card stays where it was), and with onOpen a click, a tap or Enter opens a card while Space picks it up.
• 31910ff: AI Assistant's AIMarkdown shows text wrapped with markChange as added or removed, and markdownBlocks splits Markdown into its top-level blocks. HighlightedCode takes lineChanges to mark lines a change added or removed, and copyButton={false} to leave out its Copy button. Shortcut Button takes variant='secondary', and App Shell exports useDockedPanel, which says whether the screen is wide enough for a panel beside the page.
• ef3325a: ShortcutButton takes variant='default', for the one filled action of a view.
• 2110776: ShortcutButton with listen leaves a key alone while focus is inside an element marked data-key-scope, such as a list that handles its own keys.
• 5dd8d10: Adds Text Change, the mark for text a change added or removed: added text tinted in the chart colour, removed text struck through in muted text, with “added” or “removed” for screen readers.
• 0c8f9ad: Team has a WorkloadLegend, the key under a WorkloadBar: each part's swatch, amount and what it is. Shortcut Button works without a shortcut, as an icon button with its label in a tooltip.
