Wallaby Series Release Notes


Upgrade Notes

  • Python 2.7 support has been dropped. Last release of ceilometermiddleware to support python 2.7 is OpenStack Train. The minimum version of Python now supported by ceilometermiddleware is Python 3.6.


Bug Fixes

  • Corrects retrieval of (notification) transport_url for oslo.messaging. Issue would occur when oslo.messaging RPC and Notification backends were separated.


New Features

  • Introduced option to send notifications from a background thread instead of blocking the service response to send the notification. This option is disabled by default, retaining previous behavior. Enable by setting nonblocking_notify to True in the middleware configuration. When enabled notifications will be queued for delivery in a single thread. Set send_queue_size to customize the length of this delivery queue (default size 1000).

  • Introduced option to customize the logging level using the log_level option (default WARNING).
