+## [Python 0.1.1] - 2026-04-22
+
+### Changed
+
+- Linux and Windows x86_64 wheels now target `x86-64-v3` (Haswell, 2013+) to enable AVX2 + FMA auto-vectorization in the resonator hot loop. On Linux, this is typically a 20-50x speedup over the `0.1.0` wheel. Users on pre-Haswell CPUs should install from sdist with custom `RUSTFLAGS`.
