# Events Calendar Pro 6.1.2

### Summary

Maintenance Release

The latest update ensures support for user-defined custom CSS classes in the block editor, optimizes queries for condensing recurring events when the Condense events in Series setting is enabled, and corrects the passing of null to `json_decode()` for PHP 8.1 compatibility.

As always, we recommend [testing updates](https://docs.nexcess.com/software/the-events-calendar/creating-and-using-a-wordpress-staging-site/) on a staging site first, but it should all be smooth sailing.
