**This release is breaking backward compatibility.**
The optional argument `config_lock` defaults to `False` now (i.e. after initialising the connection with the network device, it will not attempt to acquire the config DB.). NAPALM will request config lock only when required, just before trying to to load the configuration. To release (unlock), one needs to discard config or commit.
Although it was a bug, the outer key of the dictionary returned by `get_bgp_neighbors_detail` becomes `global` (previously `default`). For more info, consult https://github.com/napalm-automation/napalm-base/issues/227.
Enhancements:
- `get_route_to` returns also IPv6 routes thanks to manuel-domke, thorko and juergen-geinitz: https://github.com/napalm-automation/napalm-iosxr/pull/117
- More optional arguments: `keepalive`, `use_keys`, `key_file `, `ssh_strict`, `system_host_keys`, `alt_host_keys`, `alt_key_file`, `ssh_config_file` - https://github.com/napalm-automation/napalm-iosxr/pull/121
