+    codebase.
+  * Added BW_CXX_NO_ARRAY to control the inclusion of features depending on
+    C++ <array>.
+  * Relaxed sidechain APIs in bw_comp and bw_noise_gate to accept BW_NULL to
+    represent null sidechain inputs.
+  * Added setThreshLin() and setThreshDb() methods to the C++ APIs of bw_comp
+    and bw_noise_gate to fix naming typos without breaking the API.

+    C++/WebAssembly targets.
+  * Fixed gain compensation in bw_satur_process_multi().
+  * Fixed rounding bug in bw_phase_gen when frequency is tiny and negative.
+  * Fixed smoothing of decay parameter in bw_reverb.
