sg15 pseudo set incorrectly treated as an expermiental feature
According to the documentation, the sg15 pseudopotentials set is not experimental. However, 9.x versions of the program treat it as experimental, thus requiring ExperimentalFeatures = yes
in the input in order to avoid a Fatal Error
.
As far as I can see, the sg15 pseudos had their experimental status consciously removed in commit 076714cd (June 2018, between 8.0 and 8.1 releases).
I believe the source of the issue is commit b9dd0f66, which was a descendant of 076714cd and reintroduced a call
to messages_experimental
for sg15 pseudos. This later made its way to develop and to the 9.0 release.
