Production Evolution
EVOLUTION — Default-variant mainnet timeline for this compiler/author. Deltas highlight improvement between releases. The rightmost preview column (if present) is a sneak peek at a protocol version mainnet has not activated; its delta is computed against the latest mainnet column.
