• Add: Convert a WordPress Gallery block into a Gallery Display block from the
  block toolbar, and convert it back again. Images, captions, alt text,
  columns, link settings, alignment, spacing and colours all carry across.
• Add: A caption for the gallery itself, shown below the images. Supports bold,
  italic and links.
• Add: Left, centre and right alignment, alongside the existing wide and full.
• Add: An HTML anchor, so a gallery can be linked to directly.
• Add: Per-image alt text and captions can now be set on the block. Where they
  are, they take precedence; images without them keep following the media
  library as before, so editing an image still updates every gallery using it.
• Add: Images can open in a new tab, and images marked decorative in a
  converted gallery stay decorative.
• Change: The gallery wrapper is now a element rather than a
  , so
  the gallery caption is valid HTML. Custom CSS targeting the old element name
  may need updating.

v1.1.0

= 1.1.0 =

• Add: Image ordering controls. Order a gallery by date, title, random, or the
  order you arranged it in, with a best-fit option that places wide images in
  the mosaic layout's larger cells.
• Add: Filters that let a companion plugin register its own layout —
  gallery_display_valid_layouts in PHP, galleryDisplay.layouts and
  galleryDisplay.previewStylesheets in JavaScript.
• Security: Escape and validate block attributes before they reach the editor
  preview. A crafted attribute could previously inject markup that ran in the
  admin. The preview is now sandboxed as well.
• Security: Validate the aspect-ratio and block-gap values used in the block's
  inline styles.
• Fix: Masonry and mosaic layouts no longer keep their load-time widths when
  the browser is resized.
• Fix: The lightbox stylesheet now loads in the document head instead of after
  the page content, removing a flash of unstyled links.
• Fix: Gallery links fall back to the attachment title or caption for their
  accessible name when the image has no alt text.
• Fix: Asset cache-busting used a stale version number, so browsers could keep
  serving outdated CSS and JavaScript after an update.
• Change: Image-size labels in the block sidebar are now translatable.
