Dear all, The beta of the 2019.03 RDKit release has been tagged in github: https://github.com/rdkit/rdkit/releases/tag/Release_2019_03_1b1
There are a couple more bug fixes and maybe one more feature expected before the actual release, but I wanted to go ahead and get the beta out there. I've done conda builds for Python 3.6 and 3.7 for Windows, Mac, and Linux. 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 is below, or you can see a nicely formatted version here: https://github.com/rdkit/rdkit/releases/tag/Release_2019_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 early next week. Best, -greg # Release_2019.03.1 (Changes relative to Release_2018.09.1) ## REALLY IMPORTANT ANNOUNCEMENT - As of this realease (2019.03.1) the RDKit no longer supports Python 2. Please read this rdkit-discuss post to learn what your options are if you need to keep using Python 2: https://www.mail-archive.com/rdkit-discuss@lists.sourceforge.net/msg08354.html ## Backwards incompatible changes - The fix for github #2245 means that the default behavior of the MaxMinPicker is now truly random. If you would like to reproduce the previous behavior, provide a seed value of 42. - The uncharging method in the MolStandardizer now attempts to generate canonical results for a given molecule. This may result in different output for some molecules. ## Highlights: - There's now a Japanese translation of large parts of the RDKit documentation - SGroup data can now be read from and written to Mol/SDF files - The enhanced stereo handling has been improved: the information is now accessible from Python, EnumerateStereoisomers takes advantage of it, and it can be read from and written to CXSmiles ## Acknowledgements: Michael Banck, Francois Berenger, Thomas Blaschke, Brian Cole, Andrew Dalke, Bakary N'tji Diallo, Guillaume Godin, Jan Holst Jensen, Sunhwan Jo, Brian Kelley, Petr Kubat, Karl Leswing, Susan Leung, John Mayfield, Adam Moyer, Dan Nealschneider, Noel O'Boyle, Stephen Roughley, Takayuki Serizawa, Gianluca Sforna, Ricardo Rodriguez Schmidt, Matt Swain, Paolo Tosco, Ricardo Vianello, 'John-Videogames', 'magattaca', 'msteijaert', 'paconius', 'sirbiscuit' ## Bug Fixes: - PgSQL: fix boolean definitions for Postgresql 11 (github pull #2129 from pkubatrh) - update fingerprint tutorial notebook (github pull #2130 from greglandrum) - Fix typo in RecapHierarchyNode destructor (github pull #2137 from iwatobipen) - SMARTS roundtrip failure (github issue #2142 from mcs07) - Error thrown in rdMolStandardize.ChargeParent (github issue #2144 from paconius) - SMILES parsing inconsistency based on input order (github issue #2148 from coleb) - MolDraw2D: line width not in python wrapper (github issue #2149 from greglandrum) - Missing Python API Documentation (github issue #2158 from greglandrum) - PgSQL: mol_to_svg() changes input molecule.
