* Fixed Drop All Indexes on multisite subsites dropping indexes across every subsite instead of only the current one
* Indexes button now reads "Create All Indexes" when no indexes are selected, and "Update Active Indexes" when one or more are selected; "Create All Indexes" now creates every index regardless of checkbox state
* Promoted the existing Drop All Indexes link to a proper secondary button so it is visible whenever any indexes exist
* Checkboxes now update live as each index is created or dropped during Create/Update, and the Create/Drop buttons swap visibility automatically when the index set becomes empty or non-empty
* Added new WP All Export optimisation for when editing exports to speed up or avoid the wp_postmeta scan to grab all postmeta keys
* Added preview and customizer check for "Remove OR check for private items on front end" optimisation
* Added full namespacing for plugin update checker to prevent conflicts with 3rd party plugins
* Fixed bug with admin notice for term filtering where if you ran the rebuild from the GUI, it kept telling you it was in progress (term rebuild required to clear the notice though)
* Removed 'remove private check' option - it was causing many support issues and has limited value - it can still be added through Custom Query alterations where desired
* Moved the 'optimise group by' to operate in all cases when enabled as it has its own built-in safety checks to ensure query functionality remains identical, just faster
* Moved the 'Remove CAST' option to operate in all cases when enabled since it safely only affects the WHERE clause when implicit casting is enough for equality/inequality checks - it never runs on comparison checks like >, <, BETWEEN etc
* Performance boost for term filtering maintenance
* Removed excess debug from term maintenance optimisation
* Term filtering re-enabled with improved table maintenance performance
* Additional conditional logic added to 'remove private' optimisation to fix Mollie Payments payment-status update issue
* Term filtering optimisation disabled - accidentally went out too early
* Removed 'WHERE EXISTS' optimisation
* Upgraded check for Scalability Pro hooks to ensure JS loads on settings page
