Time-based rules
Rules that use time functions now evaluate correctly. You can write conditions such ashour_of_day(created_at) >= 22 or day_of_week(created_at) in ("Saturday", "Sunday") and Watch applies them using the transaction’s created_at timestamp.Time functions also support in and not_in for lists of hours, weekdays, or day names.Setting conditions → · Time-based examples →Previous transaction rules
Theprevious_transaction() function now works as documented. Watch looks back from the current transaction’s created_at and checks whether a matching transaction exists in that window.You can match on table fields such as source and status, or metadata paths such as meta_data.status.Setting conditions → · Compound examples →Private HTTPS rule repositories
Watch can clone and pull private rule repos over HTTPS withWATCH_SCRIPT_GIT_USERNAME and WATCH_SCRIPT_GIT_TOKEN. Username defaults to x-access-token when unset. Credentials stay out of logs and Git status responses.Configuration → · Cloud Watch config →Rule name on verdicts
