๐ Bugs fixed
๐ป 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.๐ A memory corruption was fixed when garbage collection was triggered during calls to
PyType_Ready()
of extension type subclasses. (Github issue :issue:3603
