F5 release cadence calendar
F5 moved to a monthly security cadence in July 2026. This computes the upcoming hardened-release and security-notification dates so you can plan patch windows. Local, no network.
Networking| Date (third Wednesday) | Hardened release | Security notification | Notification covers |
|---|---|---|---|
| Jul 15, 2026 | Yes | none yet | — |
| Aug 19, 2026 | Yes | Yes | Jul 15, 2026 |
| Sep 16, 2026 | Yes | Yes | Aug 19, 2026 |
| Oct 21, 2026 | Yes | Yes | Sep 16, 2026 |
| Nov 18, 2026 | Yes | Yes | Oct 21, 2026 |
| Dec 16, 2026 | Yes | Yes | Nov 18, 2026 |
Every date is a third Wednesday: that month's hardened release ships, and the previous month's security notification is published one month after the release it covers.
These are the scheduled dates. F5 also issues out-of-band security alerts and engineering hotfixes for urgent issues at any time, and retains flexibility to adjust notification timing.
