EVOLUTION — Per-compiler default-variant timeline of mainnet submissions, with an optional
preview teaser for the latest upcoming Plutus version.
Compilers with fewer than two mainnet versions are omitted (no improvement signal).
Note: preview Plutus versions may differ from the version deployed on the Cardano preview testnet. Alternative variants (BuiltinCasing, vanrossem, prepacked, …) live in the per-scenario production report.
