[Rdkit-announce] 2018.03.1 RDKit release

[Greg L. <gre...@gm...>]

 I'm pleased to announce that the next version of the RDKit - 2018.03 - is
released. The release notes are below.

The release files are on the github release page:
https://github.com/rdkit/rdkit/releases/tag/Release_2018_03_1

Binaries have been uploaded to anaconda.org (https://anaconda.org/rdkit).
The available conda binaries for this release are:
Linux 64bit: python 2.7, 3.5, 3.6
Mac OS 64bit: python 2.7, 3.5, 3.6
Windows 64bit: python 3.5, 3.6

The missing binary for python 2.7 on windows is explained here:
https://www.mail-archive.com/rdk...@li.../msg07850.html

Some things that will be finished over the next couple of days:
- The conda build scripts will be updated to reflect the new version and
new conda builds will be available in the RDKit channel at anaconda.org (
https://anaconda.org/rdkit).
- The homebrew script
- The online version of the documentation at rdkit.org (I'm traveling this
week, so this is unlikely to be done before next weekend).

Thanks to everyone who submitted code, bug reports, and suggestions for
this release!

Please let me know if you find any problems with the release or have
suggestions for the next one, which is scheduled for Octobera 2018.

Best Regards,
-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.

## Highlights:
  - An initial version of an integration with Schrodinger's coordgen
library is
    included. This produces much better 2D coordinates for complex
molecules.
  - Thanks to the move to modern C++ the RDKit is now faster and uses less
    memory
  - A number of improvements were made to the PDB reader
  - v2 of the ETKDG torsions and potentials is now available
