### v1.0.3 Changelog
**Privacy & Network Optimization**
* **Strict P2P Replication Filtering:** Nodes now only download and track hypercores from direct contacts or peers who share a Hub or Group Whisper with you. This prevents private activity from leaking to unrelated peers and significantly reduces background bandwidth.
* **Strict Message Validation:** Fixed an issue causing phantom unread badges and leaked notifications. The local database now strictly verifies your membership in a Hub or Group Whisper before accepting and storing incoming messages.
* **Transitive Group Chat Support:** You can now seamlessly receive and view messages from non-contacts inside a shared Group Whisper without needing to add them as a friend first.
**UI/UX & Bug Fixes**
* **Sidebar Hover Glitch Fixed:** Resolved the severe flickering on sidebar icons. Optimized the React component lifecycle to prevent the DOM from destroying and recreating the icons during background state updates.
* **Members Drawer Overlap Fix:** The chat area and input bar now smoothly resize and shift out of the way when the Online Users list is opened, ensuring the chat bar is never obscured on smaller screens.
