Changelog

4.4.0a1

---

⭐ New Features

• Introduce impersonation support (#599).
• Add bearer authentication support (single sign-on) (#579).
• Add Bolt 4.4 support (#560).

🩹 Fixes

• Time types use Decimals and integers instead of floats for sub-seconds (#551).
  This fixes rounding issues and allows for an exact representation of nanoseconds, but comes at the cost of a slightly altered API. Please refer to the documentation.

👏 Improvements

• Fail fast on transaction begin (#586).
• Only send qid parameter over the wire when necessary (#585).
• Reduce the number of RESET messages send over the wire to the bare minimum (#572).
• Fail fast on re-using a broken transaction (#566).

🧹Clean-up

• Drop support for Python 3.5 (end of life 2020-11-13) (#560).
