This is the new release of COPS for PHP 8.x as this fork is called (although it still supports PHP 7.4 for now).
The release file cops-1.4.3.zip has been replaced with cops-1.4.3b.zip as it was missing a few files - sorry about that...
Note: older devices may have issues with bootstrap v5 template, so your feedback would be appreciated...
Main changes include:
1.4.3 - 20230831 Sort & Filter in OPDS Catalog + Add bootstrap v5 template
incl. pull request #22 from @dunxd and php-epub-meta updates from https://github.com/epubli/epub
plus the usual code clean-up compared to previous releases
Full Changelog: 1.4.2...1.4.3
