+Django-components is still in active development.
+
+Since django-components is in pre-1.0 development, the public API is not yet frozen.
+This means that there may be breaking changes between minor versions.
+We try to minimize the number of breaking changes, but sometimes it's unavoidable.
+
+When upgrading, please read the [Release notes](../../release_notes).
+
+## Migrating in pre-v1.0
+
+If you're on older pre-v1.0 versions of django-components, we recommend doing step-wise
+upgrades in the following order:
+
+- [v0.26](../../release_notes/#v026)
+- [v0.50](../../release_notes/#v050)
+- [v0.70](../../release_notes/#v070)
+- [v0.77](../../release_notes/#v077)
+- [v0.81](../../release_notes/#v081)
+- [v0.85](../../release_notes/#v085)
+- [v0.92](../../release_notes/#v092)
+- [v0.100](../../release_notes/#v0100)
+- [v0.110](../../release_notes/#v0110)
+- [v0.140](../../release_notes/#v01400)
+
+These versions introduced breaking changes that are not backwards compatible.
