The headline is performance: Active Record serialization and record-building just got significantly faster, with gains from ten percent to nearly two times.
First, theme: less work per record. Four related changes streamline how hashes and JSON are built — skipping full attribute construction just to list names, avoiding repeated string allocations for symbol options, and skipping extra option building when tables have an inheritance column. Pull request 59655, for…
Second, theme: correctness in edge cases. For SQLite, a stacked trio fixes batched schema reading when temporary tables shadow permanent ones, when index names collide across schemas, and when table names differ only by letter case. For errors, pull request 59482 stops exception reporting from copying every view…
What's next: watch the unmerged compatibility stack for version eight point two — navigation helpers, frozen parameter parsers, and default attribute freezing — which will determine how smooth upgrades feel.
