9.0.0-beta.4 (2026-10-14)

⚠ BREAKING CHANGES

• reporting: row storage tables, provider inputs and locators are renamed to the AdCP names above, REPORTING_ROW_ENCODING_V1 is replaced by REPORTING_ROW_FORMAT_V1 and REPORTING_ROW_ALGORITHM_V1, and {period_date} renders the source timezone date as YYYY-MM-DD instead of the UTC date as yyyy/MM/dd, and a custom key template without {revision_key} is refused unless its binding is read_only. create_schema migrates existing databases; stop older writers first.
