+# Changelog
+
+All notable changes to this project will be documented in this file.
+
+This project does not have a real release cycle (yet).
+Upstream projects usually depend on development snapshots of this project.
+Still, to have some kind of indicator of small versus big change,
+we try to bump the version number (in `openeo_driver/_version.py`)
+roughly according to [Semantic Versioning](https://semver.org/).
+
+When adding a feature/bugfix without bumping the version number:
+just describe it under the "In progress" section.
+When bumping the version number in `openeo_driver/_version.py`
+(possibly accompanying a feature/bugfix):
+"close" the "In Progress" section by changing its title to the new version number
+(and describe accompanying changes, if any, under it too)
+and start a new "In Progress" section above it.
+
+
