   4 Subject: [PATCH] Follow PEP-384 when finding and opening python3 library
   5
   6 Instead of maintaining a list of all Python versions the Python 3
   7 standard defines that there MUST be a stable ABI and we can always
   8 rely on a "python3.dll" or a "libpython3.so" existing.
   9
  10 This also fixes library loading on Linux distributions that use
  11 SO versioned libraries.
