### Corrected Bugs
* Fixed: [CLI Show config JSON with multiple top-level elements is broken](https://github.com/clicon/clixon/issues/381)
* Fixed: [Non-obvious behavior of clixon_snmp after snmpset command when transaction validation returns an error](https://github.com/clicon/clixon/issues/375)
* Fixed by validating writes on ACTION instead of COMMIT since libnetsnmp seems not to accept commit errors
* Fixed: [YANG when condition evaluated as false combined with a mandatory leaf does not work](https://github.com/clicon/clixon/issues/380)
