Version 9.1.219.4 (Support Release - 3 March 2026)

Theme Management 
 Add stable version stamp to theme background URL to ensure it is cleaned from cache when changed (#147274) 
 Problem 
 
 When you change the default login background image for a theme, it does not reflect on the login page. 
 Because the browser/server caches the image, it never reloads the latest from the persistent volume on the pod. 
 
   
 Solution 
 
 Added a stable version stamp to the background image. 
 When it changes on the theme setup, it creates a new version tick; this value is retrieved by the login page and appended to the image URL. If no stamp, then we will fetch fresh from the volume. 
 
   
 Themes drop-down not loading for system menu items (#146750) 
 Problem 
 
 When a menu item is selected, the page content is loaded dynamically. 
 The themes dropdown was not being initialised as part of that process, so clicking it had no effect. 
 
   
 Solution 
 
 Added code to explicitly initialise the themes dropdown each time the page content is loaded, so it responds correctly when clicked. 
 
   
 
 Ruleset Management 
 Change Icon button on System Menu tab not working (#147268) 
 Problem 
 
 When setting up a Ruleset's System Menu, clicking the Change Icon button on any menu item had no effect — the icon picker dropdown never opened, making it impossible to change the icon for a menu item. 
 
   
 Solution  
 
 Fixed the dropdown so it opens and works correctly. When an item is clicked, the icon preview updates immediately and the selection is saved when the form is submitted. The original curated list of available icons is preserved.
