Is there a good way to retrieve the latest migration version number?

I need to implement a method in a model which behaves differently on and beyond a specific migration version.

I found assume_migrated_upto_version in connection adapter is retrieving version from database but can’t find others.

    Rails 5.2 and higher:

    > ApplicationRecord.connection.migration_context.current_version
   (0.3ms)  SELECT "schema_migrations"."version" FROM "schema_migrations" ORDER BY "schema_migrations"."version" ASC
=> 20200510093804

> ApplicationRecord.connection.migration_context.get_all_versions
   (0.3ms)  SELECT "schema_migrations"."version" FROM "schema_migrations" ORDER BY "schema_migrations"."version" ASC
=> [20191005164928,
    20191006111502,
   ...

     
    Rails up to 5.1.7:

    > ActiveRecord::Migrator.current_version
   (0.2ms)  SELECT "schema_migrations"."version" FROM "schema_migrations" 
=> 20120110085802

> ActiveRecord::Migrator.get_all_versions
   (0.3ms)  SELECT "schema_migrations"."version" FROM "schema_migrations" 
=> [20111114121610,
    20111115091108,
