CBC SDK 1.5.10

Bug Fixes

• Removed backports-datetime-fromisoformat C extension dependency. Replaced with a pure-Python fallback for Python < 3.11 that handles the Z UTC timezone designator. This fixes ModuleNotFoundError in embedded/vendored environments (e.g. Splunk) where platform-specific compiled extensions are unavailable.
