### Deprecations

Support for compact Explore URLs is deprecated and will be removed in a future release. Until then, when navigating to Explore using the deprecated format the URLs are automatically converted. If you have existing links pointing to Explore update them using the format generated by Explore upon navigation.

You can identify a compact URL by its format. Compact URLs have the left (and optionally right) url parameter as an array of strings, for example `&left=["now-1h","now"...]`. The standard explore URLs follow a key/value pattern, for example `&left={"datasource":"test"...}`. Please be sure to check your dashboards for any hardcoded links to Explore and update them to the standard URL pattern. Issue [#50873](https://github.com/grafana/grafana/issues/50873)
