+Subject: [PATCH] fixed: Python strDeviceLanguage accepts 3-char ISO codes
+ (SWIG char[3] typemap)
+
+The SWIG default char[ANY] setter uses SWIG_AsCharArray, which reserves a
+byte for a NUL terminator. strDeviceLanguage is a raw, non-terminated
+char[3] holding a 3-character ISO 639-2 code, so a valid 3-char value needs
+4 bytes and overflowed the buffer, raising a TypeError; only 2-char codes
+fit. Add member-name-scoped in/memberin typemaps that copy the raw bytes
+(str or bytes) so 3-char codes assign correctly. Scoped by name so the
+NUL-terminated strDeviceName keeps the default behaviour.

+Subject: [PATCH] fixed: build the Python wrapper against SWIG 4.5, which
+ removed the Python 2 compatibility macros
+
+SWIG 4.5 dropped the PyInt_*/PyString_* macros that pyhead.swg used to define
+for user typemaps. Two places here relied on them.
+
+The callback return handling keeps a PY_MAJOR_VERSION guard rather than moving
+to the Python 3 API outright, because the x86 Windows build still targets
+Python 2 for the EventGhost plugin. A Python 2 int is a PyIntObject, not a
+PyLongObject, so an unguarded PyLong_Check would compile there and then
+silently read every commandHandler and menuStateChanged return value as 0 - the
+one thing those callbacks exist to report. SWIG never reads SwigHelper.h, so
+the C preprocessor makes the choice and the file is SWIG-version independent.
+
+The cec_osd_name out-typemap is deleted rather than fixed, because it is dead:
+GetDeviceOSDName returns std::string, and cec_osd_name only survives as an out
+parameter in the C API, which is not wrapped. It could not have compiled if it
+ever did fire - cec_osd_name is a typedef for char[14], so the $1.name it
+dereferences has no member to name. Removing it leaves the generated wrapper
+byte-for-byte identical.
+
+Verified by preprocessing SwigHelper.h against both Python 3.10 and Python 2.7:
+Python 3 resolves to PyObject_CallObject/PyLong_AsLong with no removed macro
+surviving anywhere, Python 2 to PyEval_CallObject/PyInt_AsLong.
+
+closes #726
