* `pymongo` is NOT a requirement now, and `bson` is opt-out by default even it's installed. To enable it, set env var `MONTY_ENABLE_BSON=1`
* **SQLite storage has changed the table structure, this is NOT backward compatible, which means pre-existing sqlite db file may not be read/write after this version** (see commit 8c6ef25)

* Internal module refactored
