+## [unreleased]
+
+### 🐛 Bug Fixes
+
+- Status Colors on Monitor tab now reflect status of host. Closes #7
+- Removed unused function.
+## [0.2.0] - 2026-09-24
+
+### 🚀 Features
+
+- Added changelog
+- Added Themes
+- Added Virtual Scrolling. This allows us to scan a whole /16 subnet without overloading the UI or using a lot of RAM.
+
+### 🐛 Bug Fixes
+
+- Fixed updater to only check for newer version using proper semver checking. Before it only checked if the current in use version was different than what was available.
