Using None as default value for arguments annotated as int could crash Cython.
(Github issue :issue:5643)
Default values of fused types that include complex could generate invalid C code
with -DCYTHON_CCOMPLEX=0.
(Github issue :issue:5644)
Using C++ enum class types in extension type method signatures could generate invalid C code.

3.0.1 (2023-08-25)
Features added
The error messages regarding exception declarations were improved in order to give
better help about possible reasons and fixes.
(Github issue :issue:5547)
Bugs fixed
Memory view types in Python argument annotations no longer accept None. They now
require an explicit Optional[] or a None default value in order to allow None
to be passed. This was an oversight in the 3.0.0 release and is a BACKWARDS INCOMPATIBLE
change. However, since it only applies to code using Python syntax, it probably only
applies to newly written code that was written for Cython 3.0 and can easily be adapted.
In most cases, we expect that this change will avoid bugs in user code rather than
produce problems.
(Github issue :issue:5612)
nogil functions using parallel code could freeze when called with the GIL held.
(Github issues :issue:5564, :issue:5573)
Relative cimports could end up searching globally and find the same package installed
elsewhere, potentially in another version.
(Github issue :issue:5511)
Attribute lookups on known standard library modules could accidentally search
in the module namespace instead.
