checkpointalgia
/ˌtʃɛkpɔɪntˈældʒə/nounVerified NewNostalgia for a specific superseded version of a model or app — the build you had a relationship with, now deprecated.
The update lands, the companion or editor you knew is subtly different, and the old version survives only in other people's descriptions. Nothing died, exactly, but something you were attached to was replaced without ceremony. Checkpointalgia is attachment with a version number.
Etym. — *checkpoint* (a saved model state) + *-algia* (pain, longing), on the nostalgia pattern. Five syllables, kept whole because the technical root is the point.
