 Version `0.1.2` was prepared from [`mailschema/mailschema@eddc745`](https://github.com/mailschema/mailschema/commit/eddc7456910bf6a3c33de51c46ebf50f61ee7342).
 
 The included contribution schema has SHA-256 digest `a8a241b4837971a6251bcc135c704283536f4fb825fbbaedaf1598c6e688d564`. The canonical schemas live in the main MailSchema repository; this repository owns the Python package surface and its release history.

+The unreleased MAP contract projection is derived from [`mailschema/mailschema@ab91b37`](https://github.com/mailschema/mailschema/commit/ab91b37d29dbf95a2e208a34a144bf5f7c26d0a6). Its MAP schema digest is `d908a960f53fade9ab47876bf69b1b3d037adeb7096091e22ca71fbc3909429c`; its Content Review schema digest is `dba2a2f1e57f843f43080f5a40ced2d9c84e7c7036ec306c371a82d39f6d6c9f`. These files are projections of that source commit and do not independently define MAP.
