This release converts Hastie to Python and starts adding in various new features. If you were using any older version, it will require using all new Jinja templates and variables. Only switch if you want to redo your site, but I'll be honest I don't think anyone is using this besides myself.
The old Go code is archived on the golang branch. I do not plan to update or maintain further, which I haven't done in 4 years anyways. If you need that code fork from that branch.
Switching to Python and Jinja will give a lot more flexibility and basically renewed my interest in the tool. I've switched my mkaz.blog site over to using it. So will be adding features as I need them.
