  Changed

  • /api/events no longer spends seconds of CPU expanding recurring events.
    v4.0.0 cut the CalDAV traffic to one REPORT per calendar, but a 7-day feed still
    took 4–5 s on the production host: the 12 requests finish in about half a second,
    and the rest was the app's own recurrence expansion, which ran once per day per
    master and leaned on dayjs timezone comparisons that are slow on the Alpine image.
    Every event is now resolved once over the whole window and attributed to its days
    locally, with instants compared numerically. The 7-day expansion drops from about
    1.2 s to 0.2 s of CPU on a workstation; production is several times faster than
    that ratio suggests, because the slow calls were disproportionately slow there.

  • The response is unchanged, apart from one process-timezone-independent edge:
    "all day" for an event that is exactly one day long is now a 24 h duration check
    rather than a date step in the process zone.

  Upgrade notes

  No configuration changes and no change to the container unit. Hosts that already
  run v4.0.0 with the /api/health healthcheck pull this via podman-auto-update
  as usual. Hosts still on v3.x must first update the healthcheck line as described
  in the v4.0.0 notes.
