We are pleased to announce the Pyodide v0.29.0 release. This is a small feature release. toJs() and to_js() now convert dictionaries to Object instead of Map by default After much feedback from users, we changed toJs() and to_js() to convert dictionaries to Object by default. To opt into the old behavior, you can pass toJsLiteralMap: true to loadPyodide(). This will be removed in a future release. This was the main change motivating the feature release.
