New fields can appear in payloads as part of normalised-schema updates.

New fields can appear in payloads as part of normalised-schema updates. These additive changes are treated as backward-compatible and may not be announced in advance, since the wire format is kept additive-only. They arrive with null values where not yet computed.

• Configure your deserializer to allow (ignore) unknown fields rather than reject the whole payload.

• Rely on the webhook signature to authenticate that the payload came from Terra.

New fields are also reflected on the docs changelog.
