Nightly Builds

Nightly builds are now fully functional 👍

For now we have builds for macOS and Windows. Hopefully Linux RPM and DEB packages will follow soon...

As usual, this builds capture the latest development version (develop branch) and will contain fixes introduced on top of the latest release... and most probably will have bugs too.

Warning

In MacOS, after installing DisplayCAL you need to run the following in Terminal:

sudo xattr -dr com.apple.quarantine /Applications/DisplayCAL

3.9.15

WARNING

In MacOS, after installining DisplayCAL you need to run:

xattr -dr com.apple.quarantine /Applications/DisplayCAL.app

Release Notes

Big Items:

• Windows version should now work without a major issue. So, the previous problems about not being able to run ArgyllCMS executables has been resolved, and paths containing empty spaces are handled correctly.
• The dependency to the RealDisplaySizeMM has been removed. So DisplayCAL doesn't require any C-Extensions to be compiled and this makes it easier to install on different OSes.
• Added CI GitHub workflow for Windows.
• Lots of code refactoring and cleanup many thanks to @oldgithubman for their hard work.
• As it was getting harder to test for wxPython 4.1.1, the minimum wxPython version that we test DisplayCAL with has been upgraded to 4.2.0.
• CI GitHub tests run much faster under Linux (45-50 minutes vs 6-7 minutes) now as the tests are now using the pre-compiled wheels from wxPython website.
• Updated DisplayCAL.lib.agw from 0.9.1 to 0.9.7 from wx.lib.agw and introduced a lot of code refactoring and TypeHints on top of the original source.
• DisplayCAL development is now using the Rust tools for package management and linting. So, uv is the main package manager instead of pip and ruff replaces black and flake8.
• Removed setup.cfg, DisplayCAL is now fully using pyproject.toml for configuration. Unfortunately, we are still depending on the setup.py.

3.9.13

Release Notes

This release introduces lots of fixes, especially for Windows. The big items are:

There was an error with setup.py preventing DisplayCAL to be installed on Linux systems (macOS was working fine), thus released a new version 3.9.10.
