+### Patch Changes

+- [#118](https://github.com/CrowdStrike/ember-headless-table/pull/118) [`c02d49d`](https://github.com/CrowdStrike/ember-headless-table/commit/c02d49d0fe4f98d77404abe87ff2d8e1aefb4139) Thanks [@NullVoxPopuli](https://github.com/NullVoxPopuli)! - Address an issue where instances of plugins would be held on to after a Table is destroyed.
+
+  This caused a memory leak due how plugins, and their associated metadata, held on to
+  Table instances, which in turn, held on to the owner / container.
+
+  This was caused by the utility methods in `ember-headless-table/plugins`,
+
+  - `preferences`
+  - `meta`
+  - `options`
+
+  Because data was stored in (Weak)Maps in module-space.
+  This alone isn't a problem, but they were never cleaned up when the table was destroyed.
+
+  Cleanup of these objects could have occured via `associateDestroyableChild` and `registerDestructor`
+  from `@ember/destroyable`, but it was easier to instead have this happen automatically via hosting the
+  data needed for the "plugins utils" on the table itself. Since each plugin util requires "some instance of something",
+  be that a row, column, or table, there is a direct path to the table, and therefor a direct way to access
+  memory-scoped (Weak)Maps.
+
