Backward compatibility notes

When installing and using the 0.6.0 and newer releases of YDK-Py, please note the below issues with backward compatibility.

Installation

When installing YDK-Py, there is a new system requirement which needs to be installed. This is the libydk library, which is available on the DevHub website for various OS platforms. Please refer to the system requirements for details.

Windows Support

From release 0.6.0 onwards, YDK no longer is supported on the Windows platform. We hope to add back support for this platform in the future.

API Changes

  1. NetconfServiceProvider no longer has the close() method. There is no need to explicitly close the provider as it will be automatically cleaned up when the object goes out of scope.

  2. YFilter has replaced the functionality of the READ and DELETE objects

  3. When using YDK’s Logging, the suggested level to be used is INFO

  4. The type names of enumerations and identities no longer have Enum or Identity in their names. For example, the identity InterfaceTypeIdentity in ydk.models.ietf.ietf_interfaces is now renamed to just InterfaceType.

  5. The is_config() method is no longer available for the YDK model APIs. This may be added back in a future release.

  6. For CRUDService and other services, using a child container or list, which is not the top-level node in a yang model is no longer supported. For example:

1from ydk.models.cisco_ios_xe import Cisco_IOS_XE_bgp_oper as bgp_oper
2
3# connect to provider etc ...
4
5neighbors = bgp_oper.BgpStateData.Neighbors()
6crud.read(provider, neighbors)

now has to be changed to:

1from ydk.models.cisco_ios_xe import Cisco_IOS_XE_bgp_oper as bgp_oper
2
3# connect to provider etc ...
4
5bgp_state = bgp_oper.BgpStateData()
6crud.read(provider, bgp_state)
