We just pushed [v1.4.2](https://github.com/OpenCyphal/CETL/tree/v1.4.2) of CETL which includes a fix for a memory leak in the `variable_length_array` move constructor when using a new allocator as part of the move. See [issue #187](https://github.com/OpenCyphal/CETL/issues/187) for details and thanks to Jensen Reitz for finding this issue.
