+Started the long-pending rewrite of Easy Diffusion's server code. v4 intends to replace the Python (and PyTorch) based server with a simple C++ version. The reason for rewriting the server in C++ is to achieve sub-second startup time for the UI, and to reduce the download size (won't need to distribute Python along with Easy Diffusion) or mess with conda/venv etc. And it's also something that I want to do for personal taste, i.e. de-bloating what doesn't need to be bloated.
+
+This will also simplify the fairly messy internals and design of Easy Diffusion, which has grown organically over the years. The core of Easy Diffusion doesn't need a lot, and I plan on moving out some of the parts into server-side plugins (e.g. Cloudflare tunnels, model merging etc). v4 intends to have a clear API for plugins (on the UI side as well as on the server).
