 ## Migration from Geomap WMS Panel Plugin v1.0.1
 Due to the capability of using multiple WMS endpoints as base map layer a change in the plugin configuration object was required, not being backwards compatible with the configuration object used for plugins of version 1.y.z.

+## Dependency resolution
+Note that some of the `@grafana/*` packages also include `Openlayers` as part of their dependencies. Since the plugin itself also uses Openlayers as dependency it is required that the Openlayer versions of the `@grafana/*` packages and the one used in the panel plugin are compatible.
+This is achieved by hard-coding the `ol` version in the [`overrides` section](https://docs.npmjs.com/cli/v9/configuring-npm/package-json#overrides) of the `package.json`:
+```json
+...
+  "overrides": {
+    "ol": "7.2.2",
+    "jspdf": "3.0.2",
+    "uplot": "1.6.31"
+  },
+...
+```
+
+> ⚠️ When running in build errors after updating certain packages with [transitive dependencies](https://en.wikipedia.org/wiki/Transitive_dependency) listed in the `overrides` section it is recommend to check if the overriding versions conflict with the versions required by the updated packages
