 ## Fixed
 - [#3690](https://github.com/plotly/dash/pull/3690) Fixes Input when min or max is set to None
 - [#3723](https://github.com/plotly/dash/pull/3723) Fix misaligned `dcc.Slider` marks when some labels are empty strings
+- [#3738](https://github.com/plotly/dash/pull/3738) Add missing `stacklevel=2` to `warnings.warn()` calls so warnings report the caller's location instead of internal Dash source lines
 - [#3740](https://github.com/plotly/dash/pull/3740) Fix cannot tab into dropdowns in Safari
 - [#2462](https://github.com/plotly/dash/issues/2462) Allow `MATCH` in `Input`/`State` when the callback's `Output` has no wildcards (fixed-id Output, no Output, or `ALL`-only wildcard Output). `ALLSMALLER` still requires a corresponding `MATCH` in an Output.
