Roadmap question: Any plan to re-base F-Stack from FreeBSD 13.x to 15.x?

Hi maintainers,

I noticed that the latest official release still carries the FreeBSD 13.x user-space stack (plus selective back-ports), while FreeBSD 15.0-CURRENT has already introduced a lot of network-stack improvements (e.g. updated TCP stacks, new KPIs, iflib enhancements, etc.).

Could you share the project’s upgrade roadmap?

• Is there any plan to migrate F-Stack to FreeBSD 15.x in the next few releases?
• If yes, is there a rough timeline or target branch that contributors can start testing against?
• If not, are there technical blockers (API changes, performance risk, lack of man-power) that the community could help with?

Knowing the plan (or the lack thereof) will help downstream users decide whether to wait for 15-based bits or continue patching 13.x ourselves.

Thanks for the great work on F-Stack!

We will update FreeBSD to 15.0, The release schedule is as follows:

1. FreeBSD-15.0 release : December 2025
2. F-Stack updata to FreeBSD-15.0 : Before April 30, 2026

The above is a planned timeframe and is not guaranteed.

Great, thanks for the roadmap update!

December 2025 → April 30, 2026 sounds reasonable for most downstream planning.
