 # CHANGELOG - Whatsapp Bridge Integration
 
+## Release 0.3.0 - 2026-08-04
+- **Fix:** Discover the installed WhatsApp Bridge add-on through the Supervisor API instead of relying exclusively on the old hard-coded repository hostname.
+- **Fix:** Reuse Home Assistant's asynchronous HTTP session for status checks and message delivery.
+- **Fix:** Surface HTTP and add-on errors when sending a message instead of reporting failed requests as successful.
+
+## Release 0.2.4 - 2026-06-15
+- **Fix:** Resolved a `TypeError` in `async_get_or_create()` caused by stricter Home Assistant Core requirements demanding a `config_entry_id` for all device registry entries.
+- **Architecture Refinement:** The global "WhatsApp Bridge Hub" now utilizes a shared multi-entry architecture. It dynamically links to active configurations under a static identifier, ensuring the hub remains a single, non-duplicated entity that survives individual account deletions.
+
 ## Release 0.2.3 - 2026-06-15
 - **New (Orphaned Devices Cleaner):** Added an automatic database cleanup utility. On startup, the integration now automatically identifies and removes orphaned or "ghost" devices left behind by previous configuration changes or older versions.
 - **Fix:** Decoupled the central "WhatsApp Bridge Hub" device from specific config entry bindings. The Hub is now persistent and indestructible, preventing global entities (Broadcast and Live Status) from disappearing when individual user profiles are deleted or re-added.
@@ -21,4 +30,4 @@
 - **Improved:** The sensor is assigned to the new main device, which significantly simplifies automations (e.g., alert on connection loss).
 
 ## Release 0.1.7
-- Previous stable version
