+Changes for 1.0.0 'Peregrine Falcon':
+-------------------------------------
+
+1.0.0 is a major release of dav1d, adding important features and bug fixes.
+
+It notably changes, in an important way, the way threading works, by adding
+an automatic thread management.
+
+It also adds support for AVX-512 acceleration, and adds speedups to existing x86
+code (from SSE2 to AVX2).
+
+1.0.0 adds new grain API to ease acceleration on the GPU, and adds an API call
+to get information of which frame failed to decode, in error cases.
+
+Finally, 1.0.0 fixes numerous small bugs that were reported since the beginning
+of the project to have a proper release.
