Due to the current 2023.10.30 SRU cycle being scheduled to be released in the week of Dec-04 and most of Canonical’s teams being unavailable during the end of year/holiday season taking place between Dec-18 and Jan-01, the Kernel Team will not start a new SRU cycle in December 2023. Consequently, the next SRU cycle will begin on Jan-08. Any requests for critical or urgent fixes need to be communicated immediately to the Kernel Team.
For more details, please check the announcement post for the 2023.10.30 cycle schedule:
The up-to-date SRU schedule is also published on https://kernel.ubuntu.com/.
