+- `defaultMoverJointDef` and `defaultPogoJointDef` called C shims that were
+  missing from the package. Calling either one failed with
+  `undefined symbol: hs_b2DefaultMoverJointDef` (or `hs_b2DefaultPogoJointDef`).
+  Loading the library could fail the same way without either function being
+  called, as reported when using Template Haskell.

 ## 0.1.0.0 - 2026-11-08
 
 Initial release, bundling Box2D `v3.2.0` (upstream commit `178495b`).
