deprecations:
  - |
    OSM Information Model (IM) Debian package is no longer required, therefore
    its usage has been removed.
security:
  - |
    Security scanning has been added through the usage of the Gitlab scanners.
fixes:
  - |
    Fixes [bug 1407](https://osm.etsi.org/bugzilla/show_bug.cgi?id=1407). This
    bug was introduced due to the change from the old descriptor models into
    the new SOL006 descriptors. The Resource Orchestrator (RO) didn't received
    the information relating to port security, therefore it couldn't determine
    if the network interface should have it enabled or disabled, which in turn
    always applied the default for the used substrate.

    Fixes [bug 1408](https://osm.etsi.org/bugzilla/show_bug.cgi?id=1408). This
    bug was introduced due to the change from the old descriptor models into
    the new SOL006 descriptors. The Resource Orchestrator (RO) didn't received
    the information relating to Virtual Link Descriptor (VLD) IP Profile,
    therefore it couldn't apply the desired values for subnets and DHCP.

    Fixes [bug 1446](https://osm.etsi.org/bugzilla/show_bug.cgi?id=1446). This
    bug was introduced due to the change from the old Resource Orchestrator to
    the new Next-Generation Resource Orchestrator. For some Network Services,
    we have observed that sometimes the NS remains in state BUILDING. Checking
    in the database for ro_task we have seen that this happens because the RO
    keeps on locking always the same ro_task that has dependencies on another
    ro_task that is never executed.

    Fixes [bug 1445](https://osm.etsi.org/bugzilla/show_bug.cgi?id=1445). This
    bug was introduced due to the change from the old Resource Orchestrator to
    the new Next-Generation Resource Orchestrator. When we try to instantiate a
    service with SRIOV interfaces it fails. Debugging the error we have seen
    that the mac does not arrive to the onosof sdn plugin.

    Fixes [bug 1386](https://osm.etsi.org/bugzilla/show_bug.cgi?id=1386). This
    bug was introduced due to the change from the old Resource Orchestrator to
    the new Next-Generation Resource Orchestrator. RO has a database locking
    system intended for HA. Every worker locks a "ro_task" by writting at
    database, before performing it at the VIM, and unlocks afterwards. In case
    of a crash (e.g. POD is destroyed) the ro_task becames locked during many
    time until lock expires. The expiration time is set to 1 hour as this is
    the time that can take some ro_task (some VMs can take this time). It will
    be better having a shorter expiration time, and re-new it when needed if
    the thread that perform the VIM task is still alive. In that a way after a
    crash, new RO POD will take over the locked ro_task quite soon. The change
    has a new asyncio task that performs the renew of the locks of all the
    needed vim_threads. Vim_thread cannot do it by themselves because some VIM
    plugin operations are synchronous.

    Fixes [bug 1385](https://osm.etsi.org/bugzilla/show_bug.cgi?id=1385). This
    bug was introduced due to the change from the old Resource Orchestrator to
    the new Next-Generation Resource Orchestrator. Code creates vim_threads
    when there is new VIMs to handle (NS deployed at this VIM). However when
    the VIM is not used anymore (NS is deleted), vim_thread is not re-used in
    the next assignation. This is something that can be easily see with the
    logs. This bug does not causes malfunction, but can lead to have some
    threads overloaded. In addition resources are not free when VIM is not
    used.
