TL;DR

Open Library — Aug 18, 2026

Browsing is faster. Subject pages load results immediately while filters catch up in the background.

Book carousels are smoother, with better mobile scrolling and improved accessibility.

Search is healthier. Monitoring graphs that were broken since our Solr upgrade are restored, giving the team visibility into search performance again.

Views are now shareable. Users can bookmark or share URLs that preserve their list vs. grid preference.
