+* compat: Lower the minimum Cacti compatibility floor (INFO `compat`) from 1.2.23 to 1.2.29. On Cacti 1.2.31+ the CSP-safe `cactiReturnTo` Cancel buttons bind automatically; on 1.2.29/1.2.30 the README documents the one-time `applySkin()` snippet needed
+* security: Move the syslog pages' inline event handlers to CSP-safe bindings so the pages no longer trip Cacti's Content-Security-Policy script-src-attr directive: the confirmation Cancel buttons use the `cactiReturnTo` class, and the filter selects (plus the collapse-filters toggle) are bound via a delegated handler in `js/functions.js` keyed off a `data-onchange` attribute so each select still calls its own `applyFilter*` function
 * feature: Add Remote Data Collector processing, rules-sync, and record-storage options to the setup advisor; reject Aria selections whenever any collector option is enabled
 * change: Use TEXT for message columns previously limited to VARCHAR(2048), including existing installations
 * dev: Size the severity-legend chips to the longest label and lay them out as a CSS grid so every chip stays equal width as the legend wraps (matching the thold/monitor/servcheck/mactrack legends)

+## Cacti compatibility
+
+This plugin supports Cacti 1.2.29 and later. On Cacti 1.2.31 and later the
+confirmation-page Cancel buttons work automatically. If you are running Cacti
+between 1.2.29 and 1.2.31 (i.e. 1.2.29 or 1.2.30), please add the function
+below to the `applySkin()` function in `include/layout.js` to enable the Cancel
+buttons on forms to work:
+
+```js
+$(document).off('click.cactiReturnTo', '.cactiReturnTo')
+    .on('click.cactiReturnTo', '.cactiReturnTo', function(event) {
+        event.preventDefault();
+        cactiReturnTo($(this).attr('data-url'));
+    });
+```
+
 ## Installation
 
 To install the syslog plugin, simply copy the plugin_syslog directory to Cacti's
