+= 1.2.5 =
+
+_Release date: 2026-08-18_
+
+**Fixed**
+
+* The Hello menu item is now registered at position 1000 instead of PHP_INT_MAX. Positions are array keys in the WordPress menu array, and on WordPress 4.0-6.4 two top-level items registered at the same position overwrite each other, silently removing one of the menus. PHP_INT_MAX is one of the most popular "bottom" values in the ecosystem, so collisions were likely; 1000 sits past the last core separator (99), keeps the item at the bottom of the menu, and WordPress 6.5+ resolves any remaining collision automatically.
+
+**Compatibility**
+
+* WordPress: 4.0 - 7.1
+* PHP: 5.6 - 8.5
+* MariaDB: 11.8 (staging)
+
+**Tests**
+
+* PHP Coding Standards: 3.13.6
+* WordPress Coding Standards: 3.4.1
+* PHPStan: 2.2.8 with wp-compat (Requires at least 4.0)
+* PHPUnit: 9.6.36 (plugin header tests included, line coverage 88.5%)
+
+= 1.2.4 =
+
+_Release date: 2026-08-18_
+
+**Highlights**
+
+* Automatic updates are now handled by the ROBOTSTXT ecosystem: the bundled auto-updater was removed in favor of Manager (by ROBOTSTXT).
+
+**Added**
+
+* Dismissible notice on the Plugins screen (single site and network) when Manager (by ROBOTSTXT) is not installed and active, with a link to its plugin page.
+* Permanent, non-dismissible notice on the plugin settings page when Manager (by ROBOTSTXT) is not available.
+* Setting to remove plugin data on uninstall. Data is preserved by default unless the user explicitly opts in.
+* Uninstall routine that honors the data-removal setting.
+
+**Changed**
+
+* Author, contributor order and plugin URLs now point to the ROBOTSTXT software site (https://www.robotstxt.software/).
+* Restored the real minimum requirements after a full-range compatibility review: WordPress 4.0+ and PHP 5.6+.
+
+**Removed**
+
+* Bundled JSON-based auto-updater (robotstxt-updater.php) and update.json.
+
+**Compatibility**
+
+* WordPress: 4.0 - 7.1
+* PHP: 5.6 - 8.5
+* MariaDB: 11.8 (staging)
+
+**Tests**
+
+* PHP Coding Standards: 3.13.6
+* WordPress Coding Standards: 3.4.1

+* PHPUnit: 9.6.36 (plugin header tests included, line coverage 88.5%)
+
 = 1.2.3 =
 * Test release for update validation.

 == Description ==
-Provides a minimal Hello admin page for demonstration purposes.
+
+Adds a Hello admin page for demonstration purposes.
+
+This plugin receives its automatic updates through Manager (by ROBOTSTXT). If the manager plugin is not installed and active, a dismissible notice on the Plugins screen — and a permanent notice on the plugin settings page — will remind you to install it.
+
+== Installation ==
+
+= Automatic download =
+
+Visit the plugin section in your WordPress, search for Hello (by ROBOTSTXT); download and install the plugin.
+
+= Manual download =
+
+Extract the contents of the ZIP and upload the contents to the `/wp-content/plugins/robotstxt-hello/` directory. Once uploaded, it will appear in your plugin list.
+
+== Frequently Asked Questions ==
+
+= Why do I see a notice about Manager (by ROBOTSTXT)? =
+
+Automatic updates for this plugin are delivered through the ROBOTSTXT ecosystem by Manager (by ROBOTSTXT). Install and activate it to receive updates.
+
+== Compatibility ==
+
+* WordPress: 4.0 - 7.1
+* PHP: 5.6 - 8.5
 
 == Changelog ==
+
+= 1.2.5 =
+* Fixed a conflict on WordPress 4.0-6.4 where the Hello menu item could remove another plugin's top-level menu (and vice versa) when both used the same menu position. The menu is now registered at position 1000, past the last core separator (99), so it renders at the bottom of the menu.
+
+= 1.2.4 =
+* Updates are now delivered through Manager (by ROBOTSTXT): the bundled auto-updater was removed and a dismissible notice on the Plugins screen recommends installing the manager plugin when it is not active.
+* Added a permanent notice on the plugin settings page when Manager (by ROBOTSTXT) is not available.
+* Added a setting to remove plugin data on uninstall (data is preserved by default).
+* Restored the real minimum requirements: WordPress 4.0 and PHP 5.6, verified with a full-range compatibility scan.
+* Author, contributors and plugin URLs now point to the ROBOTSTXT software site.
+
 = 1.2.3 =
 * Test release for update validation.
 
-= 1.2.2 =
-* Removed Plugin ID (DID) from plugin header.
+= Previous versions =
 
-= 1.2.1 =
-* Test release to validate the Auto-Updater system is working correctly.
+If you want to see the full changelog, visit the [changelog](https://www.robotstxt.software/plugins/robotstxt-hello/) page.
 
-= 1.2.0 =
-* Added generic JSON-based Auto-Updater system. Plugin now updates automatically from git.robotstxt.es without depending on WordPress.org repository.
+== Compliance ==
 
-= 1.1.2 =
-* Raised the minimum WordPress requirement to 6.5 and PHP to 8.2 so the plugin matches the AGENTS development guidelines while keeping the Hello admin page untouched.
+This plugin adheres to the following security measures and review protocols for each version:
 
-= 1.1.1 =
-* Added compiled translation catalogs for supported locales (Catalan, German, Spanish, Basque, French, Galician, Italian, Polish, Portuguese) so localized greetings render without requiring manual compilation.
-
-= 1.1.0 =
-* DID Support
-
-= 1.0.5 =
-* Expanded the translation catalog to cover 202 locales with updated greetings.
-
-= 1.0.4 =
-* Documented the plugin internals with PHPDoc blocks and loaded the text domain to ensure translations are available in WordPress.
-
-= 1.0.3 =
-* Added translation files for 50 locales to improve WordPress i18n coverage.
-
-= 1.0.2 =
-* Confirmed compatibility with PHP 5.6 through PHP 8.4 via PHPCompatibilityWP checks.
-
-= 1.0.1 =
-* Broadened compatibility to cover WordPress 4.7+ and PHP 5.6+ while keeping the Hello admin page unchanged.
-
-= 1.0.0 =
-* Added the Hello admin page and menu entry.
