Tao asks about the process of updating from Hyrax 3 to 4
- Mostly changes related to the blacklight, bootstrap and rails updates will be needed in the application.
Chris asked about Ruby 3 support being added for Hyrax 4 release
- Not blocking the release for it, but would nicve to have.
Jonathan asks about tesseract 4/5 use
- Heroku makes custom software install difficult. tesseract 4 is latest version available there
- How is it being used?
  - IU uses it on every work to provide search in universal viewer
    - Using this gem:https://github.com/boston-library/blacklight_iiif_search
    - With some modification: https://github.com/IU-Libraries-Joint-Development/essi/blob/main/app/models/concerns/essi/blacklight_iiif_search/annotation_behavior.rb
- IIIF level 0 where files are just on disk, anyone using?
  - Has been used for static manifest generation
    - Chris: https://github.com/IIIF-Commons/biiif
      is the tool I was thinking of for static generation of manifests and tiles from a filesystem directory.
  - Jonathan had trouble early on getting performant IIIF server.
    - Used non-IIIF format until discovering level 0.
    - Need to use pyramidal tiff images for good performance in IIIF.
    - Number of tile files is a concern.
    - Iiliad(?) Cramer presented new image archive format. Essentially zip file with http range request support. Can IIIF level 0 support this style of files on disk?
