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].
