2sxc 19 with new Pickers and way more

Highlights

1. Finally released new EPIC picker system #3530 with things such as radio buttons and checkboxes #3179 preview features for svgs, icons and images; data-sources for App-Assets and more.
2. Created major improvements around URL parameters because of AI crawlers #3520 #3521 #3522
3. New feature to double-encrypt HTTP Post body to prevent CDN Snooping #3518
4. Language Features in UI so the user can select alternate language labels & buttons
5. Ability to delete entity-fields on content-types when the data still had relationships (old task) #1378

Minor & Chores

1. Updated UI to Angular 19 and moving most code to using Signals instead of RxJS #3527
2. Enhanced GPS fields with "my location" and custom search capabilities
3. Not a bug, but we removed an old, probably never user API called IBlockInstance (was the same as IDataSource)

Bugfixes

1. Validation on pickers caused some trouble #3525
2. Error shown on public forms because of some API being accessed for settings which wasn't needed #3477
