    One nit from ralph here

12. sock: align exception monitoring between poll() and select() backends

13. net: enforce timeout interval for paused send peers

    No need to waste a connection slot on a peer that is so slow to read as to not
    drain our send buffer down to the 1MB threshold within 20 minutes.

16. flatfile: store position as a 64 bits integer

    This is the last field that is only bounded by the usage callers make of it
    (unlike the file number, for instance). Promoting it to a 64 bits integer also
    does not change on-disk representation since we serialize positions as varints.
    Therefore, widen them to prevent any possible future misuse.

    Reviewed every cherry-pick manually and the rest automatically: all four backports match upstream exactly, and the release preparation looks correct.

    nit: this may deserve its own bullet - unless you're deliberately grouping it with the previous one

    this may need some nuance because of https://github.com/bitcoin/bitcoin/pull/36666

    fanquake commented at 6:25 PM on October 26, 2026:

    I think this is still ok, as the releases are happening at the same time, and we don't expect 29.x to receive more updates in the future.
