Dear all,
The beta of the 2018.03 RDKit release has been tagged in github:
https://github.com/rdkit/rdkit/releases/tag/Release_2018_03_1b1
I will try to get some conda builds for python 3.6 up over the next day or
so. These will 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 python=3.6
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).
You can check to see if a build is available for your platform/python
version here:
https://anaconda.org/rdkit/rdkit/files?version=2018.03.1.b1
About the builds:
- These will be done using the most recent version of conda.
- I will do the conda builds somewhat differently than I've done them
before due to the transition to modern C++ on the backend. If you encounter
problems with the beta builds, particularly the windows or linux builds,
please let me know. It is, of course, also really nice to hear if you try
things and they work!
The relevant section of the release notes is below.
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
sometime next week.
Best,
-greg
# Release_2018.03.1
(Changes relative to Release_2017.09.1)
## C++11 notes
Starting with this release, the RDKit core C++ code is written in
modern C++; for this release that means C++11.
This means that the compilers used to build it cannot be completely
ancient. Here are the minimum tested versions:
- g++ v4.8: though note that the SLN parser code cannot be built with
v4.8. It will automatically be disabled when this older compiler is
used.
- clang v3.9: it may be that older versions of the compiler also work,
but we haven't tested them.
- Visual Studio 2015: it may be that older versions of the compiler
also work, but we haven't tested them.
## Backwards incompatible changes
This release includes a set of changes to make the default arguments
to common functions less error prone (github #1679).
- MolToSmiles() now generates isomeric SMILES by default.
- The embedding code now uses the ETKDG method by default.
- MolToMolBlock() will now by default generate a set of 2D coordinates
for molecules when the includeStereo option is set to True. The
changes are made to a copy of the molecule; the molecule itself will
not be modified.
- The Mol file (and SDF) parser now determines atomic stereochemisty
based on the 3D coordinates provided (if 3D coordinates are provided).
- The SMILES parser now supports CXSMILES by default (assuming that
additional text that looks like CXSMILES extensions is there).
In every case the old behavior can be obtained by providing an
optional argument to the function(s) mentioned.
