v0.7.1

Fixed

• .ln() panic regression (0.2.10 -> 0.7.0) #46.

Changed

• Improve log implementation #38.

Documentation

• Documentation for Decimal::with_rounding_mode and Decimal::with_ctx:
  • Clarified that when changing the rounding mode, any existing extra precision (if present) is immediately rounded
    using the new rule.
  • Clarified that applying a new context may trigger traps if the current value already has signaling flags set (
    e.g., INEXACT) and the new context enables traps for those signals; this may result in a panic depending on
    build/configuration.
• Minor fixes.
