## 1 SNMP Release Notes

### 1.1 SNMP Development Toolkit 4.2

Version 4.2 supports code replacement in runtime from/to version 4.1.5.

#### 1.1.1 Improvements and new features

- [manager] Added another get, get-next and set function with another argument, `ExtraInfo` (see synchroneous get, asynchroneous get, synchroneous set, asynchroneous set, synchroneous get-next and asynchroneous get-next). This argument is passed on to the net-if process. The net-if process included in this application makes no use of this info, but other implementations might.
  Own Id: OTP-5574
  Aux Id: Seq 9850
- [manager] `report` message with incorrect security info (e.g. securtyModel and/or securityLevel) was ignored (dropped, except for incrementing the proper error counter) even if all other info was correct. This has been changed so that in this situation, the user will be informed, either via the return value from a synchronous call (see synchroneous get, synchroneous set and synchroneous get-next) or via a call to the handle_error callback function.
