case 4628 - deleting a work order made from a service request reopens the request

The request's link to the work order item blocked the delete with a database
error (500). Deleting the item now unlinks any request accepted into it and
sets it back to Open, in the same transaction, with a history entry and no
notification. Service request manual page and changelog.

 - Server: relative date filters such as "today" or "last month" (in lists and dashboard widgets) now start and end the period at midnight in the user's own [time zone](ay-start-form-data-tables.md#filtering-dates-and-time-zones). Previously, for a user in a different time zone from the server, records close to the start or end of the period could be included or left out by mistake.
 - Server: when a report fails to render, objects and errors a report script passes to `console.error` are now shown with their contents and stack (line numbers within the script) in the error message, to help with [writing report scripts](ay-report-edit.md#script-errors).
 - Server: on servers in a time zone with daylight saving time, the automatic backup could run an hour earlier or later than the chosen [backup time](ops-form-backup.md#backup-time) for part of the year; it now always runs at the chosen time on the server's clock.
+- Server: a work order created from a [customer service request](svc-csr.md#accept-to-new-work-order) can now be deleted; the request goes back to Open. Previously the delete failed with a server error.
 - Server: the SuperUser account can no longer be deleted.
 - Server: role rights corrected to match the documentation: "Service technician - restricted" users can view tax codes, projects, unit models and meter readings; "Business administration" users can view server metrics; Accounting users can no longer enter unit meter readings; only "Business administration" users can switch an [integrated application](api-integrated-applications.md) on or off or delete it.
 - Server: fixed direct notification messages to a user: only the first one within 12 hours was delivered, now every message is.
