[2.2.4] - 2 October 2026

Version 2.2.4 is a stability release. Upgrading is recommended for all RPC operators.

Changed

• The executionPlan returned by sonic_prepareBundle is now the root group of the plan itself, instead of an object holding the root group as its only step.
• sonic_prepareBundle and sonic_submitBundle no longer collapse groups with a single step into that step.
• The transaction pool now rejects bundles whose execution plan, or the plan of any bundle nested in it, has a single transaction as its root.

Fixed

• Fixed sonic_prepareBundle building single-transaction bundles without an enclosing group, which let a failing transaction be dropped from the block without its effects rolled back.
