The most visible feature of this release is support for using IIIF for image tiles, allowing all of that traffic to be scaled independently:

Other notable features:

  • OpenSeadragon has been updated to the latest version, gaining some extra performance and better touchscreen support
  • JP2 and PDF on each page are served through the bulk /data/ path, avoiding caching the same files twice and allowing that delivery subsystem to be optimized for transferring large files
  • Numerous views had significant database query optimizations, reducing page load times and server load significantly
  • Sitemaps are working again
  • The page count displayed throughout the site is AJAX-loaded and cached independently, which avoids inaccuracies due to caching and allows any page which doesn't otherwise do a Solr query to work even if Solr is overloaded
  • Search engine updates and batch loading is more efficient
  • Backslashes in Solr queries are now escaped, avoiding an HTTP 500 when Solr rejects them as invalid
