-This version is a maintenance release. 
+This is a major feature release.
 
-The focus of this release has been adding WordPress sites to Panopticon. This is now working far more reliably, allowing us to now consider support for WordPress a stable feature.

 ## 🔮 What's coming next?
 
 Development of Akeeba Panopticon takes place _in public_. You can see what we're planning, thinking of, and working on in [our issues tracker](https://github.com/akeeba/panopticon/issues).
 
+## ✨ Highlights
+
+**User Self-Registration.** Users can now register for an account on your Panopticon installation. Supports multiple registration modes (immediate, email activation, admin approval), CAPTCHA providers (ALTCHA, reCAPTCHA Invisible, hCaptcha), and password complexity validation.
+
+**Web Push Notifications.** Receive instant browser notifications for important events alongside email. Web Push works as a complementary channel, notifying you of CMS updates, backup results, security issues, and more without checking your inbox.
+
+**Core File Integrity Check.** Verify that your Joomla site's core files haven't been tampered with by comparing SHA-256 checksums against known-good values. Detects core hacks, failed updates, and potentially compromised files. Schedulable for automatic periodic checks.
+
+**PII Self-Management.** Users can now manage their personal data directly: view legal policies, manage consent, export their data, and delete their own account. Helps you comply with GDPR and similar privacy regulations.
+
+**CLI Commands for Administration.** New command-line tools for managing groups, mail templates, tasks, and backup/scanner schedules, making it easier to automate and script your Panopticon administration.
