2025-09-15 Proof Release Notes – Proof Help Center

The 2025-09-15 Proof release (DEPLOY-1179) updates the system to honor API-set transaction expiration times—preventing signers from starting transactions past those times and applying account default timezones if none are specified—with this opt-in feature for business and real estate API users becoming the default later in September.

Summary: Transaction expiration times set by API will be respected instead of defaulting to midnight

Fixes

The system will respect the transaction expiry time if set by the API, rather than all transactions expiring at midnight. Now, signers will not be able to start transactions past the specified expiration time. If timezone offset is not provided, the account’s default timezone settings will be applied. See API documentation (BIZ-8344).
