About 10 IDLE features were implemented as supposedly optional extensions. Their different behavior could be confusing or worse for users and not good for maintenance. Hence the conversion. The main difference for users is that user configurable key bindings for builtin features are now handled uniformly. Now, editing a binding in a keyset only affects its value in the keyset. All bindings are defined together in the system-specific default keysets in config-extensions.def. All custom keysets are saved as a whole in config-extension.cfg. All take effect as soon as one clicks Apply or Ok. The affected events are '<>', '<>', '<>', '<>', '<>', '<>', '<>', and '<>'. Any (global) customizations made before 3.6.3 will not affect their keyset-specific customization after 3.6.3. and vice versa.

Update and augment description of the configuration system. .. .. bpo: 30983 .. date: 2017-08-18-17-19-23 .. nonce: ggGz9z .. section: Tools/Demos gdb integration commands (py-bt, etc.) work on optimized shared builds now, too. :pep:`523` introduced _PyEval_EvalFrameDefault which inlines PyEval_EvalFrameEx on non-debug shared builds. This broke the ability to use py-bt, py-up, and a few other Python-specific gdb integrations. The problem is fixed by only looking for _PyEval_EvalFrameDefault frames in python-gdb.py.

CPython has provided the own implementation for thread-local storage (TLS) on Python/thread.c, it's used in the case which a platform has not supplied native TLS.
