Claude Opus 4.8 migration notice replaces 4.7 reference
Anthropic updated the Claude Opus model documentation to reference migration to version 4.8 instead of 4.7. This indicates a new model version (Opus 4.8) has been launched, replacing the previously documented 4.7. Users on Opus 4.6 or older should migrate to 4.8.
