Delete Entry Versions plugin for Craft CMS
The plugin adds a utility to delete entry versions.
Delete Entry Versions is available in the Plugin Store. You can also install the plugin manually from the command line with the following commands.
> composer require carlcs/craft-deleteentryversions > ./craft install/plugin delete-entry-versions
You can find the utility in Utilities → Delete Entry Versions in the Control Panel.
The function provided deletes all entry versions of all of your entries. The current version of each entry is retained though, making it possible to revert back to it later.
