+# Changelog
+
+## v0.5.0 - 2020-10-15
+
+✨ NEW: Add `tabbed` directive, to create tab groups!
+See [this documentation section](https://sphinx-panels.readthedocs.io/en/latest/#tabbed-content).
+
+♻️ REFACTOR: Move from CSS to SCSS:
+Under the hood, sphinx-panels now utilises CSS compiled from source SCSS,
+allowing for a better development environment.
+The CSS files are also "hashed", to ensure that documentation using sphinx-panels will not show
+old, cached CSS stylings after future updates to sphinx-panels.
