• Consider a function returning the data calculated by DrawMol::extractSGroupData() (github issue #7829 from ZontaNicola)
• Legend position (github issue #9023 from PaulC61)
• Speed-up tautomer canonicalization, no API changes (github pull #9134 from pechersky)
• If templates match, skip ring number check (github pull #9217 from ZontaNicola)
• Add some std::ranges support (github pull #9218 from greglandrum)
• [bot] Update molecular templates header file (github pull #9234 from github-actions[bot])

Documentation:

• Add more pyi patches, 2026-03 (github pull #9214 from pechersky)
• mention AI tools in the contrib guidelines (github pull #9224 from greglandrum)

Bug Fixes:

• Tautomer insensitive hash v2, E/Z and stereocenter-preservation (github pull #9128 from eloyfelix)
• Misplaced parentheses in shape code (github pull #9222 from DavidACosgrove)
• Incorrect UFF Inversion term gradient for P/As/Sb/Bi centers (github issue #9229 from scal444)
• Make setDoubleBondNeighborDirections() more consistent (github pull #9239 from ricrogz)
• Heap-use-after-free in RDKit cleanupStereoGroups via duplicate CXSMILES stereo group atom index (github issue #9259 from arthurscchan)

Cleanup work:

• Cleanup/get atoms and bonds (github pull #9243 from greglandrum)

Highlights

Backwards incompatible changes:

• Since #9208, atom rings are "normalized" so that the first atom in the ring definition is the one with the lowest index, and the second one is the neighbor to the first which also has the lowest index.

Code removed in this release:

Deprecated code (to be removed in a future release):

Highlights

• A significant number of known SMILES canonicalization problems were resolved.
• It's now possible to provide your own matching functions to supplement or replace the defaults when doing substructure matching.
• An experimental new implementation of shape-based alignment using Gaussians.
• Improvements to the molecular templates for 2D depiction and handling of macrocycles in the templates.

Backwards incompatible changes:

• The Dict class (and therefore all the properties interfaces) has been updated to std::string_view keys. This is transparent to the Python interfaces,
