Dear all, The beta of the 2020.03 RDKit release has been tagged in github: https://github.com/rdkit/rdkit/releases/tag/Release_2020_03_1b1
I've done conda builds for Python 3.6 and 3.7 for Mac, and Linux and I'm working on the Windows builds now. These all use the beta label so that they do not install by default; you'll need to run "conda install" as follows: conda install -c rdkit/label/beta rdkit Be sure to confirm that it's installing the right version when you are prompted (if there's no build available, it will pick the current production release instead). The relevant section of the release notes (which still may need a highlight or two added) is below, or you can see a nicely formatted version here: https://github.com/rdkit/rdkit/releases/tag/Release_2020_03_1b1 As usual, if you have time to try out the new release I would love feedback. If nothing major comes up, I plan to do the actual release next Monday. Best, -greg # Release_2020.03.1 (Changes relative to Release_2019.09.1) ## Backwards incompatible changes - Searches for equal molecules (i.e. `mol1 @= mol2`) in the PostgreSQL cartridge now use the `do_chiral_sss` option. So if `do_chiral_sss` is false (the default), the molecules `CC(F)Cl` and `C[C@H](F)Cl` will be considered to be equal. Previously these molecules were always considered to be different. - Attempting to create a MolSupplier from a filename pointing to an empty file, a file that does not exist or sometihing that is not a standard file (i.e. something like a directory) now generates an exception. - The cmake option `RDK_OPTIMIZE_NATIVE` has been renamed to `RDK_OPTIMIZE_POPCNT` # Highlights: - The drawings generated by the MolDraw2D objects are now significantly improved and can include simple atom and bond annotations (#2931 and #3010) - An initial implementation of a modified scaffold network algorithm is now available (#2911) - A few new descriptor/fingerprint types are available - BCUTs (#2957), Morse atom fingerprints (#1773), Coulomb matrices (#2993), and MHFP and SECFP fingerprints (#2643) ## Acknowledgements: Marcel Baltruschat, Jason Biggs, Eliane Briand, Ben Cornett, David Cosgrove, Zhenting Gao, Guillaume Godin, Gareth Jones, Zachary Kaplan, Eisuke Kawashima, Steven Kearnes, Brian Kelley, Maxim Koltsov, Mieszko Manijak, Dan Nealschneider, Daniil Polykovskiy, Daniel Probst, Steve Roughley, Kevin Ryan, Vincent F.

Both `message()` and `Invariant::getMessage()` will be removed in the next release. - The old MolHash code should be considered deprecated. This release introduces a more flexible alternative. Specifically the following pieces will be removed in the next release: - The python functionality `rdkit.Chem.rdMolHash.GenerateMoleculeHashString()` - The C++ functionality directly present in the header file `GraphMol/MolHash/MolHash.h`
