Zed Series Release Notes


Upgrade Notes

  • Python 3.6 & 3.7 support has been dropped. The minimum version of Python now supported is Python 3.8.

Bug Fixes

  • The BGP service plugin RPC queue has been added to RPC workers, like it is done in other Neutron service plugins (l3-plugin, metering, etc.). This fixes RPC requests and AMQP heartbeats not getting processed in time, causing AMQP connection dropping, and other unpredictable unwanted behavior. See bug 1974057.

  • In preparation for the upcoming SQLAlchemy 2.0 release, several fixes have been made regarding the use of context decorators. See bugs 1980671 and 1984238.

  • Multiple issues in the implementation of the StaticScheduler have been fixed that may have caused peers to be erroneously descheduled. See bug 1980235.


New Features

  • A new BGP scheduler has been added, called StaticScheduler. It will not perform any automatic scheduling of speakers to agents, instead relying on API calls to perform explicit scheduling, fulfilling the needs of larger deployments. See also bug 1920065. The plan is to make the StaticScheduler the default option for the next release and possibly deprecate the current default, ChanceScheduler.
