v0.1.6

What's Changed

• Added helpful ImportError messages for missing optional extras (ebm, anam, pin subpackages) so users get clear install guidance instead of cryptic ModuleNotFoundError
• Fixed Tweedie objective to pass variance_power parameter correctly
• Removed driver_age from monotone-increasing constraints (U-shaped relationship, not monotone)
• Fixed score() docstring to clarify units of y
• Added Python 3.13 to test matrix
• Closed 5 Dependabot security alerts via transitive dep pins (werkzeug, flask, pyasn1)
