IMPORTANT NOTICE (SRU CYCLE ANNOUNCEMENTS):
Beginning with the current (2025.10.13) cycle, we will not be announcing
the start of the SRU cycles through mailing lists as done in the past.
Please follow the “Kernel SRU” posts at discourse.ubuntu.com for the
start of the cycle announcements.
[1] Due to internal events taking place, 2025.10.13 cycle is scheduled to
take 5 weeks instead of 4. And this is the last SRU cycle in 2025.
For CVEs and important fixes/changes we plan to use the s2025.10.13
security cycle as a cleanup release. It will contain no upstream
stable sets and changes submitted after Oct-08 will require explicit
requesting and approval to be picked into s2025.10.13!
[2] Tentative versions, subjected to change.
