ScyllaDB Sphinx Theme 1.1 is now released 🥳

We’ve made a number of updates to update all our dependencies to the latest version and introduced new directives you can use to write great docs.

You can read more about all notable changes here.

⚠️Breaking changes

Before, the theme installed poetry 1.1.x as a dependency to manage Python dependencies. However, poetry 1.2.x changed the installation method. Therefore, we've decided to #307 Make poetry a prerequisite so that you can decide to install the poetry version you prefer.

To preview the docs locally, you should uninstall the previous version of poetry. Then, install the latest version:

1. Uninstall Poetry 1.1.x.

curl -sSL https://raw.githubusercontent.com/python-poetry/poetry/master/get-poetry.py | POETRY_UNINSTALL=1 python -

2. Install Poetry 1.2.x. For detailed instructions, see Poetry installation.

How to test this PR

2. Uninstall poetry 1.1 and install poetry 1.2. For more information, see Breaking changes notice above.

3. Enter the docs folder, and run:

4. Open http://127.0.0.1:5500/ with your favorite browser. The doc should render without errors, and the version should be Sphinx Theme version (see the footer) must be 1.1.x:
