 ### Changed 🔧
 
+- ⚠️ BREAKING: Removed `slice_join_eps` from `PlineBooleanOptions`. This is breaking for any code
+  that interacts with this option struct directly (does not use defaults). `slice_join_eps` was
+  also removed from the equivalent `cavc_pline_boolean_o` struct in the C FFI.
+  ([#31](https://github.com/jbuckmccready/cavalier_contours/pull/31))
 - ⚠️ BREAKING: `PlineSource::create_aabb_index` and `PlineSource::create_approx_aabb_index` now
   just return a `StaticAABB2DIndex` rather than an `Option<StaticAABB2DIndex>`. The equivalent C api
   calls `cavc_pline_create_aabbindex` and `cavc_pline_create_approx_aabbindex` also no longer
   return an error code of 2 when polyline has less than 2 vertexes (empty aabb index is returned).
-  ([#29](https://github.com/jbuckmccready/cavalier_contours/pull/29)).
+  ([#29](https://github.com/jbuckmccready/cavalier_contours/pull/29))
 - Updated `StaticAABB2DIndex` dependency to version 1.0.
 - Bumped rust edition to 2021.
