Hi @mcrisp1972 @desrosj, Added the PR for the same, ​https://github.com/WordPress/wordpress-develop/pull/7159

Thank You,

@desrosj, We can continue with the PR raised up to 6.7, if there is any new version for underscore added before 6.7 update, I can add that version to this PR.

Thank You,

Thanks @hbhalodia! Could you also update wp-includes/script-loader.php to indicate the correct version for the scripts->add( 'underscore' ); call?

Sure, I would update the PR.
