NEW-0618-1: grouping in deal aggregation
POST /v1/deals/aggregate accepts groupBy: "stageSemanticId" — a breakdown by stage semantics (in progress, won, lost) for funnel analytics.
NEW-0618-2: pagination and filter for stage history
GET /v1/stage-history supports pagination (meta.total, meta.hasMore) and a filter by entity type entityTypeId.
FIX-0618-3: task time tracking does not reassign the author
Before
PATCH /v1/tasks/:taskId/time/:id accepted a userId field, but Bitrix24 does not reassign the record author — the value was silently ignored.
After
The userId field is rejected with 400 — the author of a time-tracking record cannot be changed.
Impact on integrators
Do not pass userId when updating a time-tracking record.
FIX-0618-4: calendar event time zone
Before
PATCH /v1/calendar-events/:id could save the time in the Bitrix24 user's time zone rather than the event's own.
After
The event time zone is preserved on update.
