+*   Add public method for checking if a table is ignored by the schema cache.
+
+    Previously, an application would need to reimplement `ignored_table?` from the schema cache class to check if a table was set to be ignored. This adds a public method to support this and updates the schema cache to use that directly.
+
+    ```ruby
+    ActiveRecord.schema_cache_ignored_tables = ["developers"]
+    ActiveRecord.schema_cache_ignored_tables?("developers")
+    => true
+    ```
