@jfgrimm Is there a public statement somewhere that announces this?

If so, we should mention it in the PR description, maybe also in the commit message?

[jfgrimm]

@boegel I haven't been able to find one, still looking

[boegel]

Recent release announcements still point to xorg.freedesktop.org/archive, see for example https://lists.x.org/archives/xorg/2025-June/062056.html

@jfgrimm As discussed in Slack, a better alternative is probably to introduce new XORG_* constants that provide tuples of source URLs, so both will be tried?

@boegel The page indicates that freedesktop.org and x.org are both primary download sites for X, and there are multiple mirrors as well. I support introducing new XORG_* constant tuples containing primary download sites and mirrors to improve this.

@jfgrimm Can you look into failing CI?

[jfgrimm]

@boegel will take a look, I think it's failing on the from-commit test

[jfgrimm]

@boegel not sure how to best tackle the failing from_commit tests hitting the deprecation warning

@jfgrimm We'll need to update those to using a different/newer commit.

If we already open an easyconfig PR for easyconfigs using the SYSTEM toolchain (like ncurses-6.2.eb) to stop using the deprecated constants like GNU_SOURCE, we can already bump the commit used in test_from_commit even though the easyconfig PR isn't merged yet (it can only be merged after this PR got merged)...

[jfgrimm]

I've currently got easybuilders/easybuild-easyconfigs#23299 open, which updates the use in all easyconfigs
Want me to split ncurses out into a separate PR, or is one large PR OK for the test?
