# Fedora's own librandombytes spec (Georg Sauthoff, rhbz#2464809), from Fedora 45's
# librandombytes-20240318-2, rebuilt in the PQConnect COPR for the Fedora releases that do not
# ship it yet. Release 2 matches Fedora 45, so upgrading replaces it with Fedora's build; the
# only change is a fixed Release instead of rpmautospec's %%autorelease.
