API Impact Report: Custom Message Handlers

Audience: dapp developers, contract developers, wallet implementors

Breaking Changes

The one behavioral change is that unknown message types now panic instead of being silently ignored. Previously, a message with an unrecognized type ID would produce a debug log and be discarded. Now:

• An unrecognized ID in the reserved range (< 2^16) panics with a link to /errors/2
