A new HTML-aware ERB engine is landing in Rails, and it could change how you write templates.

The big news is the proposed Herb engine [1], which parses HTML and ERB into a single syntax tree, using Prism for the Ruby parts, promising a more semantic understanding of your templates. Jean Boussier is also shipping fixes across the stack: a RedisCacheStore bug with redis-client that broke clear and stats [2], a PostgreSQL exclusion constraint parsing fix for multiline expressions [3], and in Sprockets, a fix so the "ignore_mtime" option is properly inherited between environments [4], all culminating in the 4.4.1 release [5]. These are the maintenance touches that keep production humming, and Herb is the one to watch for the future.

Action items

→ Review the Herb pull request and test it against your ERB templates rails/rails [plan]
→ Upgrade sprockets to 4.4.1 to get the ignore_mtime inheritance fix rails/sprockets [immediate]
→ Verify your RedisCacheStore clear/stats methods work with redis-client after the fix rails/rails [monitor]
