+## New Features and Enhancements:
+  - Exclude Zero order bonds  from FindRingFamilies() and add arguments for includeDativeBonds, includeHydrogenBonds
+ (github pull #9118 from ricrogz)
+
+## Bug Fixes:
+  - Get things working with numpy 2.4 and pandas 3.0
+ (github pull #9072 from greglandrum)
+  - Chemdraw build fails on Big-endian: `cs_swapBytes.h: error: parse error in template argument list`
+ (github issue #9077 from barracuda156)
+  - Another canonicalization fix
+ (github pull #9082 from ricrogz)
+  - CopyMolSubset silently rewires bonds when bondIndices reference atoms not in atomIndices
+ (github issue #9084 from mcs07)
+  - CopyMolSubset ignores bondIndices when all atoms are included
+ (github issue #9088 from mcs07)

+  - Further refactoring in SSSR finding
+ (github pull #9104 from ricrogz)
+
+## Documentation:
+  - fix the python docs for CanonicalRankAtomsInFragment
+ (github pull #9087 from greglandrum)
+ - Confusing Deprecation Warning regarding GetImplicitValence
