+- Updated 8th December 2025 with ComfyUI version `0.3.76`
 
-The current official ComfyUI portable has two disadvantages, firstly it does not come with Git portable which is occasionally required by custom node packs,
-and the latest version come with Python 3.13 by default which still has (few) compatibility issues with some extensions.
+The current official ComfyUI portable has two slight disadvantages, firstly it does not come with Git portable which is occasionally required by custom node packs or
+to automatically models etc, and the latest versions come with Python 3.13 by default which still has (few) compatibility issues with some extensions.
 
-0.3.49 was the last version that came with Python 3.12.10, you can still download it from the official github, and I placed a backup in this HF.

+So I am updating this version based on Python 3.12 with the latest updates and included Git and the [ComfyUI-Manager](https://github.com/Comfy-Org/ComfyUI-Manager) node.
+Recently I added some custom scripts with which you can easily modify the embedded Python environment too.

+This portable version contains all components required to use ComfyUI without needing to install any additional components. The only thing your system needs are the Microsoft
+Visual C++ runtimes, but if you are not using a naked Windows install it is very likely that you already have those. If you don't have them you can download them here:  
+
+* Latest Microsoft Visual C++ Redistributable Installer  
+https://aka.ms/vc14/vc_redist.x64.exe
 
-Additionally I created a "v2" version that includes Git and the ComfyUI-manager custom node (which is really essential). If you don't have a
-system-wide Git installation you should run it with the "_v2.bat" so it sets up the path correctly. Otherwise no modifications have been made.
+After you unzip the archive you will find a few batch files in the main directory which must be used to run and modify the portable environment.
 
-Occasionally I will post updated versions of the UI that will still include Python 3.12.
