 ## Version 0.1.0 - 2025-12-13
 
-A new system monitoring tool, rtop, has been added. It provides real-time information about CPU, memory, processes, network, disk, and filesystem usage.
+The application now includes a CPU tab with core usage and temperature details. Users can view memory, process, network, disk, and filesystem statistics, along with improved memory detail views.
