get_currentuserinfo is depricated

Using the WordPress query monitor plugin, I see many errors that look like they are originating from the amember plugin. The errors all read as follows:

There is an article about this on Stack Ooverflow : https://stackoverflow.com/questions...4-5-use-wp-get-current-user-i#answer-36595049

Can I just do a straight up replace operation?
get_currentuserinfo
to
wp_get_current_user()

Might want to consider updating the code as get_currentuserinfo
appears to be outdated.

Here is wp-content/plugins/amember4.php from the plugin.
Is there a newer version of this plugin I should be using, my amember install is at the latest version.

PHP:

Yep, installed new plugin and all errors have cleared. Might be a good idea to rename the plugin to amember5.x to reflect the fact that it has been updated. Thanks
