 # Recent Changes
 
+-   0.5.5
+    - [#116](https://github.com/petgraph/fixedbitset/pull/116): Add functions for counting the results of a set operation (`union_count`, 
+       `intersection_count`, `difference_count`, `symmetric_difference_count`) by @james7132.
+    - [#118](https://github.com/petgraph/fixedbitset/pull/118): Shrink the stack size of FixedBitset. There should be zero stack size overhead
+      compared to a Vec.
+    - [#119](https://github.com/petgraph/fixedbitset/pull/119): Fix builds for wasm32.
+    - [#121](https://github.com/petgraph/fixedbitset/pull/121): Add support for SIMD acceleration for AVX builds.
 -   0.5.4
     - [#112](https://github.com/petgraph/fixedbitset/pull/112): Fix undefined behavior in IntoOnes and setup testing with MIRI by @SkiFire13
