"Over Yet" follows on from last month's "Roses/Lotus/Violet/Iris", which features additional vocals from boygenius (Phoebe Bridgers, Lucy Dacus and Julien Baker).
The new single is the seventh track to be lifted from Petals For Armor, after Williams dropped the first part of her debut album as an EP in February.
She was going to release a second EP before the full album, but due to the coronavirus pandemic, Williams has chosen to "release each song from Petals For Armor II, individually."
