<Update label="v1.1.1" description="13 Aug 2026">
  `improvement`

  Relative time-range inputs now reject week and year units up front with a clear message instead of failing as a provider error, since Fourth supports only days and calendar months. List actions that take only optional filters now state that the query object must always be included in the call, because omitting it entirely is rejected before the request is made. Documented the response-size and filtering limits of the list actions so callers stop hitting truncated results and gateway timeouts. List Employees now explains that its time range filters by when a record last changed rather than by hire date, and that showFormer=false and no time range should be used to look up a specific person. List Absences and List Pay Parts now explain that each call covers the whole organisation and that the date range must be kept narrow enough to complete within the gateway timeout. List Next of Kin, List Accrual and List Employments now state that Fourth offers no pagination and no per-employee filter, so results must be matched client-side.

<Update label="v1.1.0" description="5 Aug 2026">
  `bugfix`

  Fixed List Employees and List Next of Kin returning HTTP 400 (absent optional query parameters were sent as the literal string "null"). Corrected create/update/delete success messages for absences, holidays, and multiple employments to reflect that Fourth processes these asynchronously, so a SubmissionID does not confirm the change was applied. Clarified that relative time-range inputs accept only days and calendar months (weeks and years are not supported by the provider).
