This is a “heads-up” email about a (non-breaking) major version update
with a (non-disruptive) license change in the fast_float package in Rawhide.
Once I have a successful scratch build in the PR[1], I plan to update
fast_float from 4.0.0 to 5.0.0.
ABI changes are impossible because this is a header-only library; the
upstream release notes[2] do not describe any breaking API changes; and
I have verified compatibility of all dependent packages via local mock
builds. Given all of that, I am not treating this as a breaking update
even though the major version number is incremented.
A significant change in this release is the addition of Boost (BSL-1.0)
as an additional disjunctive license option. The package license
therefore changes from
Apache-2.0 OR MIT
to
Apache-2.0 OR MIT OR BSL-1.0
Since fast_float is a header-only library, and our guidelines treat
these as a kind of static library, directly-dependent packages
should—strictly speaking—include fast_float’s SPDX license expression in
their own. I will take care of the necessary change for c4core[3].
