+# MiniOS v2.1.3 | Architectural update & RP2350 support
+
+## Overview
+
+This update is mainly focused on RP2350 microcontroller support. I also added a new experimental GUI-style settings menu. It is mostly vibe-coded for now so it does not work very well yet, but I will improve it ASAP.
+
+I also added experimental wallpapers. I really liked the style, so in future updates I will probably make more wallpapers for each theme.
+
+## New Features
+
+- RP2350 support and new architectural changes to better separate devices from each other
+
+> Pin config for RP2350 Pi Zero Waveshare
+
+```c id="89x2ls"
+#define TFT_CS 17
+#define TFT_RST 20
+#define TFT_DC 26
+#define TFT_MOSI 19
+#define TFT_SCLK 18
+```
+
+- New experimental settings menu
+- Experimental wallpaper support
+
+## Improvements
+
+- **Improved `name` command** - now it works more like an actual app setup flow in the terminal and asks the user for a username
+- **Display buffering improvements & terminal bugs addressed** - I made a small mistake in the `renderScreen()` function that caused the last line to sometimes not render properly
