  commit ca056f4499c259c0de68ed7cefad7ee7b62bfa43
  Author: Paolo Bonzini <pbonzini@xxxxxxxxxx>
  Date:   Wed May 3 12:48:02 2023 +0200
  
      Python: Drop support for Python 3.7
      
      Debian 10 is not anymore a supported distro, since Debian 12 was
      released on June 10, 2023.  Our supported build platforms as of today
      all support at least 3.8 (and all of them except for Ubuntu 20.04
      support 3.9):
      
      openSUSE Leap 15.5: 3.6.15 (3.11.2)
      CentOS Stream 8:    3.6.8  (3.8.13, 3.9.16, 3.11.4)
      CentOS Stream 9:    3.9.17 (3.11.4)
      Fedora 37:          3.11.4
      Fedora 38:          3.11.4
      Debian 11:          3.9.2
      Debian 12:          3.11.2
      Alpine 3.14, 3.15:  3.9.16
      Alpine 3.16, 3.17:  3.10.10
      Ubuntu 20.04 LTS:   3.8.10
      Ubuntu 22.04 LTS:   3.10.12
      NetBSD 9.3:         3.9.13*
      FreeBSD 12.4:       3.9.16
      FreeBSD 13.1:       3.9.18
      OpenBSD 7.2:        3.9.17
      
      Note: NetBSD does not appear to have a default meta-package, but offers
      several options, the lowest of which is 3.7.15. However, "python39"
      appears to be a pre-requisite to one of the other packages we request
      in tests/vm/netbsd.
      
      Since it is safe under our supported platform policy, bump our
      minimum supported version of Python to 3.8.  The two most interesting
      features to have by default include:
      
      - the importlib.metadata module, whose lack is responsible for over 100
        lines of code in mkvenv.py
      
      - improvements to asyncio, for example asyncio.CancelledError
        inherits from BaseException rather than Exception
      
      In addition, code can now use the assignment operator ':='
      
      Because mypy now learns about importlib.metadata, a small change to
      mkvenv.py is needed to pass type checking.

  commit ca056f4499c259c0de68ed7cefad7ee7b62bfa43
  Author: Paolo Bonzini <pbonzini@xxxxxxxxxx>
  Date:   Wed May 3 12:48:02 2023 +0200
  
      Python: Drop support for Python 3.7
      
      Debian 10 is not anymore a supported distro, since Debian 12 was
      released on June 10, 2023.  Our supported build platforms as of today
      all support at least 3.8 (and all of them except for Ubuntu 20.04
      support 3.9):
      
      openSUSE Leap 15.5: 3.6.15 (3.11.2)
      CentOS Stream 8:    3.6.8  (3.8.13, 3.9.16, 3.11.4)
      CentOS Stream 9:    3.9.17 (3.11.4)
      Fedora 37:          3.11.4
      Fedora 38:          3.11.4
      Debian 11:          3.9.2
      Debian 12:          3.11.2
      Alpine 3.14, 3.15:  3.9.16
      Alpine 3.16, 3.17:  3.10.10
      Ubuntu 20.04 LTS:   3.8.10
      Ubuntu 22.04 LTS:   3.10.12
      NetBSD 9.3:         3.9.13*
      FreeBSD 12.4:       3.9.16
      FreeBSD 13.1:       3.9.18
      OpenBSD 7.2:        3.9.17
      
      Note: NetBSD does not appear to have a default meta-package, but offers
      several options, the lowest of which is 3.7.15. However, "python39"
      appears to be a pre-requisite to one of the other packages we request
      in tests/vm/netbsd.
      
      Since it is safe under our supported platform policy, bump our
      minimum supported version of Python to 3.8.  The two most interesting
      features to have by default include:
      
      - the importlib.metadata module, whose lack is responsible for over 100
        lines of code in mkvenv.py
      
      - improvements to asyncio, for example asyncio.CancelledError
        inherits from BaseException rather than Exception
      
      In addition, code can now use the assignment operator ':='
      
      Because mypy now learns about importlib.metadata, a small change to
      mkvenv.py is needed to pass type checking.
