  https://spdx.org/licenses/

is versioned. It's at version 3.5 and the -only/-or-later tags have been

Well, the problem was that people started to use them and argued that they
are the new standard, which is true. So we decided to allow both. See:

Nothing. Leave them alone. Both are valid and tools have to deal with them
anyway.
