Description Ionen Wolkens gentoo-dev 2025-04-23 12:20:21 UTC
<qtbase-6.8.0 (incl. Qt5), and qtbase-6.9.0 are not affected, but 6.9.0 is masked and not a stable candidate, so 6.8.3-r1 is patched instead.

Given Qt 6.8.3 is still in middle of stabilization (bug #953873), and that I'd rather not split stabling a new revbump in another bug. I went ahead and did 6.8.3-r1 by keeping current stable keywords while hoping patch won't regress anything.

Still need bug #953873 to be done to stabilizes on the remaining arches then cleanup 6.8.2+6.8.3-r0 though.
