My latest version, with basic JavaScript support, improved widget embedding features, and more kinks worked out. Version 4 is the most stable and full featured TkinterWeb release to date!
In version 4.3, TkinterWeb was split into TkinterWeb and TkinterWeb-Tkhtml. This was done to work towards Bug #52 and to reduce download size when updating. Some minor bugs were also addressed. Python 3.2+ is now required.
The API changed significantly in version 4. See https://tkinterweb.readthedocs.io/en/latest/upgrading.html for details on how to migrate your code. Enjoy!
