== Summary
#checkuser database tables are undergoing a migration that will remove the `cuc_ip` column from `cu_changes`. #mediawiki-extensions-loginnotify uses this column, though for deprecated code. To avoid a migration the integration should be removed
== Background
* {T363487} describes the migration that is removing the `cuc_ip` column from the `cu_changes` table
** The #mediawiki-extensions-loginnotify extension reads data from the `cu_changes` table and uses `cuc_ip` to query for the data
*** This query uses a SQL LIKE query which won't be as easily replicable for the replacement `cuc_ip_hex` column
* To avoid a potentially costly migration, the deprecated functionality should be dropped to reduce the maintenance burden and solve the use of the deprecated database column that is slated for removal
== Acceptance criteria
* [ ] #mediawiki-extensions-loginnotify no longer queries CheckUser database tables
