Extensions updates Started By cjsailer Hello, I'm a bit confused by the Extensions screen where it shows all your installed extensions (with your current version) and also the upgrade versions available. Two extensions as an example, IFrame and Links I'm on version 8.1.3 and 8.0.2 respectively, and versions 9.1.3 and 8.2.0 are listed as available upgrades.

CSS Priority changing between releases? Started By cjsailer Hello, I attempted to update our test enviornment from 10.02.02 to 10.02.05.

What’s inside this new version Better performance Fewer bugs That one annoying thing finally fixed after ...	1	211	1	4/15/2026 7:05 AM by Mariette Knap (SU)
