Thanks for reporting this. Would you mind dropping us a screenshot of where you're seeing this error? I suspect that this error is likely coming from a plugin or theme that needs an update to work with 6.1.0 -- but a little additional information will help me track down the issue!

The culprit for me is: sequential woocommerce order numbers I had to deactivate it for it to work

+1, another report for this happening with 'WooCommerce Sequential Order Numbers Pro' in 4685271-zd-woothemes. Looks like something the plug-in authors need to fix.

Another case in 4683773-zd-woothemes where WP-CLI shows the message: The is_ajax function is deprecated since version 6.1.0. Replace with wp_doing_ajax.

Thanks for bringing this up. Best to get in touch with SkyVerge for support on this issue -- hopefully they'll be able to get an update out for their plugin quickly!
