Simon Willison released micropython-wasm 0.1a2, with the main change being a new CLI. The CLI was added from issue #7 and was inspired while drafting a related post about MicroPython in a sandbox. Its purpose is to make the post's “Try it yourself” section easier to demonstrate and follow, especially for readers experimenting with Python, WebAssembly, and sandboxing.
Simon Willison released micropython-wasm 0.1a1, a small update connected to Python, sandboxing, and WebAssembly. The release fixes limitations that appeared while he was trying to use it to build datasette-agent-micropython. The post does not list detailed changes, so this should be read as an early usability and compatibility improvement rather than a major feature launch.
