+- Update bitvec to version 1.1.5.0.
+  # 1.1.5.0
+
+  * Make `zipBits` unconditionally strict in its second bit
+    vector argument (thanks to @treeowl).
+
+  * Add `simd` flag (enabled by default) to use a C SIMD
+    implementation for `zipBits`, `invertBits`, `countBits`,
+    `bitIndex`, `nthBitIndex`, `selectBits`, `excludeBits`,
+    `reverseBits` (thanks to @konsumlamm).
+
+  * Decomission `libgmp` flag.
