+Changelog
+=========
+
+9.0.1
+-----
+
+    * Fix potential ABI issue in SVE support, making ``xsimd::sve`` a type alias to
+      size-dependent type.
+
+9.0.0
+-----
+
+    * Support fixed size SVE
+
+    * Fix a bug in SSSE3 ``xsimd::swizzle`` implementation for ``int8`` and ``int16``
+
+    * Rename ``xsimd::hadd`` into ``xsimd::reduce_add``, provide ``xsimd::reduce_min`` and ``xsimd::reduce_max``
+
+    * Properly report unsupported double for neon on arm32
+
+    * Fill holes in xsimd scalar api
+
+    * Fix ``find_package(xsimd)`` for xtl enabled xsimd
+
+    * Replace ``xsimd::bool_cast`` by ``xsimd::batch_bool_cast``
+
+    * Native ``xsimd::hadd`` for float on arm64
+
+    * Properly static_assert when trying to instantiate an ``xsimd::batch`` of xtl complex
+
+    * Introduce ``xsimd::batch_bool::mask()`` and ``batch_bool::from_mask(...)``
+
+    * Flag some function with ``[[nodiscard]]``
+
+    * Accept both relative and absolute libdir and include dir in xsimd.pc
+
+    * Implement ``xsimd::nearbyint_as_int`` for NEON
+
+    * Add ``xsimd::polar``
+
+    * Speedup double -> F32/I32 gathers
+
+    * Add ``xsimd::slide_left`` and ``xsimd::slide_right``
+
+    * Support integral ``xsimd::swizzles`` on AVX
+
+8.1.0
+-----
+
+    * Add ``xsimd::gather`` and ``xsimd::scatter``
+
+    * Add ``xsimd::nearbyint_as_int``
+
+    * Add ``xsimd::none``
+
+    * Add ``xsimd::reciprocal``
+
+    * Remove batch constructor from memory adress, use ``xsimd::batch<...>::load_(un)aligned`` instead
+
+    * Leave to msvc users the opportunity to manually disable FMA3 on AVX
+
+    * Provide ``xsimd::insert`` to modify a single value from a vector
+
+    * Make ``xsimd::pow`` implementation resilient to ``FE_INVALID``
+
+    * Reciprocal square root support through ``xsimd::rsqrt``
+
+    * NEON: Improve ``xsimd::any`` and ``xsimd::all``
+
+    * Provide type utility to explicitly require a batch of given size and type
+
+    * Implement ``xsimd::swizzle`` on x86, neon and neon64
+
+    * Avx support for ``xsimd::zip_lo`` and ``xsimd::zip_hi``
+
+    * Only use ``_mm256_unpacklo_epi<N>`` on AVX2
+
+    * Provide neon/neon64 conversion function from ``uint(32|64)_t`` to ``(float|double)``
+
+    * Provide SSE/AVX/AVX2 conversion function from ``uint32_t`` to ``float``
+
+    * Provide AVX2 conversion function from ``(u)int64_t`` to ``double``
+
+    * Provide better SSE conversion function from ``uint64_t`` to ``double``
+
+    * Provide better SSE conversion function to ``double``
+
+    * Support logical xor for ``xsimd::batch_bool``
+
+    * Clarify fma support:
+
+        - FMA3 + SSE -> ``xsimd::fma3<sse4_2>``
+        - FMA3 + AVX -> ``xsimd::fma3<avx>``
