Python 3.12

[EwoutH]

Python 3.12 is now in the Beta phase and will be released in a few months. This means it's going to be heavily tested the next few months. It would be great if AppVeyor could add Python 3.12 to it's images.

• Ubuntu images
• Windows images
  • Visual Studio 2019 image
  • Visual Studio 2022 image
• macOS

We wouldn't want to risk breaking any other users builds by installing a beta. But you could always add something like this to your appveyor.yml config file for your own testing.

install:
  - ps: |
      $version = "3.12.0"
      $beta = "b2"
      Write-Host "Installing Python $version" -ForegroundColor Cyan

      $downloadUrl = "https://www.python.org/ftp/python/$version/python-$version$beta-amd64.exe"
      Write-Host "Downloading $($downloadUrl)..."
      $exePath = "$env:TEMP\python-$version$beta.exe"
      (New-Object Net.WebClient).DownloadFile($downloadUrl, $exePath)
      
      Write-Host "Installing..."
      cmd /c start /wait $exePath /quiet TargetDir="$targetPath" Shortcuts=0 Include_launcher=1 InstallLauncherAllUsers=1 Include_debug=1
      Remove-Item $exePath
      
      Start-ProcessWithOutput "$targetPath\python.exe --version"
      
      Write-Host "Installed Python $version" -ForegroundColor Green

Users will only install 3.12 if they specifically select it right? I'm not talking about changing the default Python version, just adding another version.

The 3.12 release candidate 1 is now out (with RC2 due next week), and the release manager is asking maintainers to test:

There will be no ABI changes from this point forward in the 3.12 series, and the goal is that there will be as few code changes as possible.

Call to action

We strongly encourage maintainers of third-party Python projects to prepare their projects for 3.12 compatibilities during this phase, and where necessary publish Python 3.12 wheels on PyPI to be ready for the final release of 3.12.0.

Python 3.12.0 final is now out! 🚀

Is there an ETA for Python 3.12 support to be released? Thanks.

I know that people are saying to move to psycopg3 but I have a lot invested in psycopg2. So please release a version for python 3.12

Sadly it's hard to take Appveyor serious as a CI vendor anymore, especially with such a heads-up.

On GitHub Actions, Python 3.12 was natively available from the alpha phase, almost a year ago.
