v0.14.0

Features

• before_send hook: new before_send= option on booboo.init(). Inspect or modify every event before
  transmission, or return None to drop it. Enables value-level PII scrubbing (IBANs, payment references, emails inside
  variable values) that the built-in name-based scrubber can't do. If the hook raises, the event is dropped — never sent
  unscrubbed.

See the docs for details and a scrubbing example.
