The short version

What changed, and why it matters

This commit updates the Tron coin support in Trezor firmware to use the newer 'session' API and changes the Tron message type numbers. It also removes unused Tron transaction-signing message definitions and limits Tron support to debug builds only. There is no direct evidence in the commit of a security vulnerability being fixed; it appears to be a maintenance and integration cleanup change.

Recommended action

No immediate security action required. Treat as routine maintenance. If Tron support is intended for production, ensure follow-up commits re-enable it for release builds and complete security review of the full Tron app (address derivation, path validation, and any future signing logic).

Security signals we found

01

API migration from client to session (architectural hardening)

02

Removal of unused Tron transaction signing protobuf messages reduces attack surface

03

Tron support restricted to debug builds only

04

Message type renumbering to avoid collision with future message IDs

05

No changelog entry, but commit title describes routine fix
