The effective date on the DPA should have been February 7, because we
didn't actually update the zulip.com website until that day.
(This commit was added to the internal zulip.com branch during
deployment of the last DPA update, so users always saw the correct
information).
The clarification is in Section 4.1:
Previously: ... from time to time engage additional third parties for
the purpose of providing the Services, including without limitation
the processing of Personal Data.
New: ... from time to time engage additional third parties for the
purpose of providing the Services, including without limitation the
processing of Personal Data, in accordance with Section 4.2 below.
