+> This document records feature updates and bug fixes for the Luxsin B9 controller. Entries are listed in reverse chronological order — the newest release appears first.

+## v2026.08.17
+
+### Changes
+- Removed the "Legacy version" entry from the home page. The legacy Web UI is no longer being updated or maintained — please use this new Web UI for the best experience.
 
 ## v2026.08.06
 
 ### New Features
 - Added a "What's New" entry on the home page, allowing you to view release notes online.
-- Added Undo support on the EQ page: tap the Undo button to revert your most recent change. It covers band parameter edits (frequency / gain / Q / filter type), slider drag adjustments, preamp and auto-preamp changes, A/B mode copy & switch, and batch edits. Each undo shows a toast describing exactly what was reverted (e.g. "A Band 3 GAIN +2.0 → 0.0").
