Exception position reporting could run into race conditions on threaded code. It now uses function-local variables again.
Error handling early in the module init code could lead to a crash.
Error handling in cython.array creation was improved to avoid calling C-API functions with an error held.
A memory corruption was fixed when garbage collection was triggered during calls to PyType_Ready() of extension type subclasses. (Github issue #3603)
Memory view slicing generated unused error handling code which could negatively impact the C compiler optimisations for parallel OpenMP code etc. Also, it is now helped by static branch hints. (Github issue #2987)
Cython's built-in OpenMP functions were not translated inside of call arguments. Original patch by Celelibi and David Woods. (Github issue #3594)
Complex buffer item types of structs of arrays could fail to validate. Patch by Leo and smutch. (Github issue #1407)
Decorators were not allowed on nested async def functions. (Github issue #1462)
C-tuples could use invalid C struct casting. Patch by MegaIng. (Github issue #3038)
Optimised %d string formatting into f-strings failed on float values. (Github issue #3092)
When importing the old Cython build_ext integration with distutils, the additional command line arguments leaked into the regular command. Patch by Kamekameha. (Github issue #2209)
When using the CYTHON_NO_PYINIT_EXPORT option in C++, the module init function was not declared as extern "C". (Github issue #3414)
Three missing timedelta access macros were added in cpython.datetime.
The signature of the NumPy C-API function PyArray_SearchSorted() was fixed. Patch by Brock Mendel. (Github issue #3606)
