Vinegar 2.1
When upgrading from Vinegar 1.x to Vinegar 2.x, there are a number of breaking changes, so please be sure to read the release notes for Vinegar 2.0 as well.
When upgrading from Vinegar 2.0 to 2.1, no special precautions have to be taken. As long as you do not modify the configuration, Vinegar 2.1 will behave exactly like Vinegar 2.0.
If you want, you can use the new provide_python_modules option that is now
supported by the vinegar.template.jinja module. Please refer to the module
documentation for details
