By end of November per usual testing period.
dev-libs/icu-75.1, this time for real.
Note that boost-1.86.0 won't be a candidate for this. It looks like a bad 'un.
There are problems with installed poppler headers in app-text/poppler-24.10.0 for which the fix is too big for my taste to backport. Hence the early switch to app-text/poppler-24.11.0-r1 stabilisation.
