We have moved to using Sphinx's autodoc to create the Python API documentation.
epydoc
, the tool we used to use, is no longer actively developed and only supports
Python2. There will undoubtedly be problems associated with the change; if you notice
anything missing in the documetation or something that's really badly formatted,
please either let us know or submit a PR with a fix.
This release includes a set of changes to make the default arguments to common functions less error prone (github #1679).
- GetAtomSmiles() now generates isomeric SMILES by default.
- The ringMatchesRingOnly option to the FindMCS() function now applies to atom-atom matches as well as bond-bond matches.
- The Python functions EmbedMolecule() and EmbedMultipleConfs() now use the ETKDG algorithm by default instead of standard distance geometry.
- This release includes two contributions from the Google Summer of Code:
- A new generalized fingerprint generator.
- An integration/port of MolVS to the core RDKit. The API on both of these may change a bit with future releases.
- The rdkit.Chem.Draw module now includes functions for depicting fingerprint bits. Morgan and RDKit fingerprints are currently supported.

(Changes relative to Release_2017.09.1)
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.
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.

(Changes relative to Release_2015.09.2)
In order to build the RDKit, it is now necessary to have at least v1.7 of numpy installed.
Note: The RDKit has the wonderful "problem" that there are a lot of contributors and it's tough for me to capture them all to put together release notes. I don't even know many of the contributors (which is awesome!) The names here come largely from what I pull in an automated way from github. In cases where there's no real name listed in github, I either guessed or used just the github alias in quotes. If I got it wrong, please let me know!

new
Draw.PrepareMolForDrawing()
function takes care of standard tasks like wedging bonds, kekulization, and adding chiral Hs.Draw.MolsToGridImage()
can generate SVGs and uses the new molecular drawing code for PNGs when possible. The Jupyter notebook integration uses the new drawing code when possible. - Error and warning messages from the C++ core can now be displayed in the Jupyter notebook

The large scale changes in the handling of stereochemistry were made for this release. These should make the code more robust.
-
If you are building the RDKit yourself, changes made in this release require that you use a reasonably up-to-date version of flex to build it. This is likely to be a problem on Redhat, and redhat-derived systems. Specifically: if your version of flex is something like 2.5.4 (as opposed to something like 2.5.33, 2.5.34, etc.), you will need to get a newer version from http://flex.sourceforge.net in order to build the RDKit.
-
Changes only affecting C++ programmers:
- The code for calculating topological-torsion and atom-pair fingerprints has been moved from $RDBASE/Code/GraphMol/Descriptors to $RDBASE/Code/GraphMol/Fingerprints.
- The naming convention for methods of ExplicitBitVect and SparseBitVect have been changed to make it more consistent with the rest of the RDKit.
- the bjam-based build system should be considered deprecated. This is the last release it will be actively maintained.
(Changes relative to Release_Q42009_1)
- Andrew Dalke, Jean-Marc Nuzillard, Noel O'Boyle, Gianluca Sforna, Nik Stiefl, Anna Vulpetti
- Substantial improvements were made to the SLN parser
- A bad depiction case was fixed. (issue 2948402)
- Hs added to planar carbons are no longer in the same plane as the other atoms. (issue 2951221)
- Elements early in the periodic table (e.g. Mg, Na, etc.) no longer have their radical counts incorrectly assigned. (issue 2952255)

- The MaxMin diversity picker can now be given a seed for the random number generator to ensure reproducible results.
- the vflib source, which is no longer used, was removed from the External source tree. It's still available in svn at rev1323 or via this tarball: http://rdkit.svn.sourceforge.net/viewvc/rdkit/trunk/External/vflib-2.0.tar.gz?view=tar&pathrev=1323
- the directory Contrib has been added to the RDKit distribution to house contributions that don't necessarily fit anywhere else. The first contribution here is a collection of scripts required to implement local-environment fingerprints contributed by Anna Vulpetti.
- Some optimization work was done on the molecule initialization code: reading in molecules is now somewhat faster.
- Some optimization work was done on the RDK and Layered fingerprinting code.
(Changes relative to Release_Q32009_1)
- A bug fix in the SMARTS parser has changed the way atom-map numbers in Reaction SMARTS are parsed. Earlier versions of the RDKit required that atom maps be specified at the beginning of a complex atom query: [CH3:1,NH2]>>[:1]O The corrected version only accepts this form: [CH3,NH2:1]>>[:1]O This change may break existing SMARTS patterns.
- A switch to using cmake as the build system instead of bjam has made the RDKit much easier to build.
- Andrew Dalke, Kirk DeLisle, David Hall, Markus Kossner, Adrian Schreyer, Nikolaus Stiefl, Jeremy Yang
- the SMARTS parser now correctly requires tha atom-map numbers be at the end of a complex atom query. (issue 1804420)

- The KNN code now supports weighted nearest-neighbors calculations with a radius cutoff.
- The lapack dependency has been completely removed from the RDKit.
- The supported build system for the RDKit is now cmake (http://www.cmake.org) instead of bjam. See the file INSTALL for the new installation instructions. Files for bjam are still included in the distribution but are deprecated and will be removed in a future version.
(Changes relative to Release_Q22009_1)
- Due to bug fixes in the boost random-number generator, RDK fingerprints generated with boost 1.40 are not backwards compatible with those from earlier versions.

- $RDBASE/Projects/DbCLI/SDSearch.py has been removed; use the CreateDb.py and SearchDb.py scripts in the same directory instead.
- the BRICS code has been refactored
(Changes relative to Release_Q42008_1)
- The directory structure of the distribution has been changed in order to make installation of the RDKit python modules more straightforward. Specifically the directory $RDBASE/Python has been renamed to $RDBASE/rdkit and the Python code now expects that $RDBASE is in your PYTHONPATH. When importing RDKit Python modules, one should now do: "from rdkit import Chem" instead of "import Chem". Old code will continue to work if you also add $RDBASE/rdkit to your PYTHONPATH, but it is strongly suggested that you update your scripts to reflect the new organization.
- For C++ programmers: There is a non-backwards compatible change in the way atoms and bonds are stored on molecules. See the ## Other section for details.
- Kirk DeLisle, Noel O'Boyle, Andrew Dalke, Peter Gedeck, Armin Widmer
- Incorrect coordinates from mol2 files (issue 2727976)

- BRICS implementation
- Morgan/circular fingerprints implementation
- The 2D pharmacophore code now uses standard RDKit fdef files.
- Atom parity information in CTABs now written and read. If present on reading, atom parity flags are stored in the atomic property "molParity".
- An optional "fromAtoms" argument has been added to the atom pairs and topological torsion fingerprints. If this is provided, only atom pairs including the specified atoms, or torsions that either start or end at the specified atoms, will be included in the fingerprint.
- Kekulization is now optional when generating CTABs. Since the MDL spec suggests that aromatic bonds not be used, this is primarily intended for debugging purposes.
- the removeStereochemistry() (RemoveStereoChemistry() from Python) function has been added to remove all stereochemical information from a molecule.
- The Qt3-based GUI functionality in $RDBASE/rdkit/qtGui and $RDBASE/Projects/SDView is deprecated. It should still work, but it will be removed in a future release. Please do not build anything new on this (very old and creaky) framework.
- The function DaylightFingerprintMol() is now deprecated, use RDKFingerprintMol() instead.
- For C++ programmers: The ROMol methods getAtomPMap() and
getBondPMap() have been removed. The molecules themselves now support
an operator method that can be used to convert graph iterators
(e.g. ROMol:edge_iterator, ROMol::vertex_iterator,
ROMol::adjacency_iterator) to the corresponding Atoms and Bonds.
New API for looping over an atom's bonds:
... molPtr is a const ROMol * ...
... atomPtr is a const Atom * ...
ROMol::OEDGE_ITER beg,end;
boost::tie(beg,end) = molPtr->getAtomBonds(atomPtr);
while(beg!=end){
const BOND_SPTR bond=(*molPtr)[*beg];
... do something with the Bond ...
++beg;
}
New API for looping over a molecule's atoms:
... mol is an ROMol ...
ROMol::VERTEX_ITER atBegin,atEnd;
boost::tie(atBegin,atEnd) = mol.getVertices();
while(atBegin!=atEnd){ ATOM_SPTR at2=mol[*atBegin]; ... do something with the Atom ... ++atBegin; }
(Changes relative to Release_Q32008_1)
- A fix in the handling of stereochemistry in rings means that the SMILES generated with this release are different from those in previous releases. Note that the canonicalization algorithm does not work in cases of pure ring stereochemistry : the SMILES should be correct, but it is not canonical. Rings containing chiral centers should be fine.

- MolOps::getMolFrags() can now return a list of split molecules instead of just a list of atom ids. (request 1992648)
- ROMol::getPropNames() now supports the includePrivate and includeComputed options. (request 2047386)
- the pointers returned from Base64Encode/Decode are now allocated using new instead of malloc or calloc. the memory should be released with delete[].
- the generation of invariants for chirality testing is now quite a bit faster; this results in faster parsing of molecules.
- The use of C include files instead of their C++ replacements has been dramatically reduced.
- The new (as of May2008) hashing algorithm for fingerprints is now the default in the python fingerprinting code (Chem.Fingerprints.FingerprintMols).
- The functions MolOps::assignAtomChiralCodes() and MolOps::assignBondStereoCodes() are deprecated. Use MolOps::assignStereochemistry() instead.
- The RDKit no longer uses the old numeric python library. It now uses numpy, which is actively supported.
- By default Lapack++ is no longer used. The replacement is the boost numeric bindings: http://mathema.tician.de/software/boost-bindings.
(Changes relative to Release_Jan2008_1)
- A fix to the values of the parameters for the Crippen LogP calculator means that the values calculated with this version are not backwards compatible. Old values should be recalculated.
- topological fingerprints generated with this version may not be compatible with those from earlier versions. Please read the note below in the "## Other" section.
- Please read the point about dummy atoms in the "## New Features" section. It explains a change that affects backwards compatibility when dealing with dummy atoms.
- Some of the bugs fixed in this release were found and reported by Adrian Schreyer, Noel O'Boyle, and Markus Kossner.

- isotope information (and other atomic modifiers) are now correctly propagated by chemical reactions (issue 1934052)
- triple bonds no longer contribute 2 electrons to the count for aromaticity (issue 1940646)
- Two bugs connected with square brackets in SMILES were fixed (issues 1942220 and 1942657)
- atoms with coordination numbers higher than 4 now have tetrahedral stereochemistry removed (issue 1942656)
- Bond.SetStereo() is no longer exposed to Python (issue 1944575)
- A few typos in the parameter data for the Crippen logp calculator were fixed. Values calculated with this version should be assumed to not be backwards compatible with older versions (issue 1950302)
- Isotope queries are now added correctly (if perhaps not optimally) to SMARTS.
- some drawing-related bugs have been cleared up.
- A bug in Chem.WedgeMolBonds (used in the drawing code) that was causing incorrect stereochemistry in drawn structures was fixed. (issue 1965035)
- A bug causing errors or crashes on Windows with [r] queries was fixed. (issue 1968930)
- A bug in the calculation of TPSA values in molecules that have Hs in the graph was fixed. (issue 1969745)
- Support for supplying dummy atoms as "[Du]", "[X]", "[Xa]", etc. is now considered deprecated. In this release a warning will be generated for these forms and in the next release the old form will generate errors. Note that the output of dummy atoms has also changed: the default output format is now "*", this means that the canonical SMILES for molecules containing dummies are no longer compatible with the canonical SMILES from previous releases. (feature request 186217)
- Atom and bond query information is now serializable; i.e. query molecules can now be pickled and not lose the query information. (feature request 1756596)
- Query features from mol files are now fully supported. (feature request 1756962)
- Conformations now support a dimensionality flag. Dimensionality information is now read from mol blocks and TDT files. (feature request 1906758)
- Bulk Dice similarity functions have been added for IntSparseIntVect and LongSparseIntVect (feature request 1936450)
- Exceptions are no longer thrown during molecule parsing. Failure in molecule parsing is indicated by returning None. Failure to open a file when reading a molecule throws BadFileExceptions (feature requests 1932875 and 1938303)
- The various similarity functions for BitVects and SparseIntVects now take an optional returnDistance argument. If this is provided, the functions return the corresponding distance instead of similarity.
- Some additional query information from Mol files is now translated
when generating SMARTS. Additional queries now translated:
- number of ring bonds
- unsaturation queries
- atom lists are handled better as well (feature request 1902466)
- A new algorithm for generating the bits for topological fingerprints has been added. The new approach is a bit quicker and more robust than the old, but is not backwards compatible. Similarity trends are more or less conserved.
- The molecule drawing code in Chem.Draw.MolDrawing has been modified so that it creates better drawings. A new option for drawing that uses the aggdraw graphics library has been added.
- The RingInfo class supports two new methods: AtomRings() and BondRings() that return tuples of tuples with indices of the atoms or bonds that make up the molecule's rings.
- Changes in the underlying boost random-number generator in version 1.35 of the boost library may have broken backwards compatibility of 2D fingerprints generated using the old fingerprinter. It is strongly suggested that you regenerate any stored fingerprints (and switch to the new fingerprinter if possible). There is an explicit test for this in $RDBASE/Code/GraphMol/Fingerprints/test1.cpp
- The unofficial and very obsolete version of John Torjo's v1 boost::logging library that was included with the RDKit distribution is no longer used. The logging library has been replaced with the much less powerful and flexible approach of just sending things to stdout or stderr. If and when the logging library is accepted into Boost, it will be integrated.
- The DbCLI tools (in $RDBASE/Projects/DbCLI) generate topological fingerprints using both the old and new algorithms (unless the --noOldFingerprints option is provided). The default search uses the newer fingerprint.
- The directory $RDBASE/Data/SmartsLib contains a library of sample SMARTS contributed by Richard Lewis.
(Changes relative to Release_Aug2007_1)
- Bug fixes in the canonicalization algorithm have made it so that the canonical SMILES from this version are not compatible with those from older versions of the RDKit.
- Please read the point about dummy atoms in the "## New Features" section. It explains a forthcoming change that will affect backwards compatibility when dealing with dummy atoms.
- The build system has been completely changed. Makefiles and Visual Studio project files have been removed. See the "## Other" section for more info.
- Adrian Schreyer uncovered and reported a number of the bugs fixed in this release.
- the Recap code no longer generates illegal fragments for highly-branched atoms. (issue 1801871)
- the Recap code no longer breaks cyclic bonds to N (issue 1804418)
- A bug in the kekulization of aromatic nitrogens has been fixed (issue 1811276)
- Bugs in the Atom Type definitions for polar carbons and positive nitrogens in BaseFeatures.fdef have been fixed. (issue 1836242)
- A crash in the sanitization of molecules that only have degree 4 atoms has been fixed; it now generates an exception. The underlying problem with ring-finding in these systems is still present. (issue 1836576)
- Mol files for molecules that have more than 99 atoms or bonds are no longer incorrectly generated. (issue 1836615)
- Problems with the sping PIL and PDF canvases have been cleared up. The PIL canvas still generates a lot of warnings, but the output is correct.
- The query "rN" is now properly interpreted to be "atom whose smallest ring is of size N" in SMARTS queries. It was previously interpreted as "atom is in a ring of size N". (issue 1811276) This change required that the default feature definitions for aromaticity and lumped hydrophobes be updated.
- The MolSuppliers (SDMolSupplier, TDTMolSupplier, SmilesMolSupplier) no longer fail when reading the last element. (issue 1874882)
- A memory leak in the constructor of RWMols was fixed.
- A problem causing rapid memory growth with Recap analysis was fixed. (issue 1880161)
- The Recap reactions are no longer applied to charged Ns or Os (issue 1881803)
- Charges, H counts, and isotope information can now be set in reactions. (issue 1882749)
- The stereo codes from double bonds (used for tracking cis/trans) are now corrected when MolOps::removeHs is called. (issue 1894348)
- Various small code cleanups and edge case fixes were done as a result of things discovered while getting the VC8 build working.
- The SparseIntVect class (used by the atom pairs and topological torsions) is now implemented in C++.
- The package $RDKit/Python/Chem/MolDb has been added to help deal with molecular databases. (this was intended for the August release and overlooked)
- The module $RDKit/Python/Chem/FastSDMolSupplier has been added to provide a fast (at the expense of memory consumption) class for working with SD files. (this was intended for the August release and overlooked)
- A new directory $RDKit/Projects has been created to hold things that don't really fit in the existing directory structure.
- The new project $RDKit/Projects/DbCLI has been added. This contains command-line scripts for populating molecular database and searching them using substructure or similarity.
- The code for calculating some descriptors has been moved into C++ in the new module Chem.rdMolDescriptors. The C++ implementation is considerably faster than the Python one and should be 100% backwards compatible.
- The MaxMinPicker (in Code/SimDivPickers) supports two new options:
- the user can provide a set of initial picks and the algorithm will pick new items that are diverse w.r.t. to those
- the user can provide a function to calculate the distance matrix instead of calculating it in advance. This saves the N^2 step of calculating the distance matrix.
- A new piece of code demo'ing the use of the RDKit to add chemical functionality to SQLite is in Code/Demos/sqlite. This will eventually move from Demos into Code/sqlite once some more functionality has been added and more testing is done.
- The distance geometry embedding code now supports using random initial coordinates for atoms instead of using the eigenvalues of the distance matrix. The default behavior is still to use the eigenvalues of the distance matrix.
- The function Recap.RecapDecompose now takes an optional argument where the user can specify the minimum size (in number of atoms) of a legal fragment. (feature request 180196)
- Dummy atoms can be expressed using asterixes, per the Daylight spec. Dummy atoms are also now legal members of aromatic systems (e.g. c1cccc1 is a legal molecule). Support for supplying dummy atoms as "[Du]", "[X]", "[Xa]", etc. is now considered deprecated. In the next release a warning will be generated for these forms and in the release after that the old form will generate errors. Note that the output of dummy atoms will also change: in the next release the default output format will be "". (feature request 186217)
- A proof of concept for doing a SWIG wrapper of RDKit functionality has been added in: $RDBASE/Code/Demos/SWIG/java_example. This isn't even remotely production-quality; it's intended to demonstrate that the wrapping works and isn't overly difficult.
- The full set of tests is now easier to setup and run on new machines. (issue 1757265)
- A new build system, using Boost.Build, has been put into place on both the windows and linux sides. The new system does much better dependency checking and handles machine-specific stuff a lot better. The new system has been tested using Visual Studio 2003, Visual Studio Express 2005, Ubuntu 7.10, and RHEL5.
- The "Getting Started in Python" document has been expanded.
- There's now an epydoc config file for building the python documentation ($RDBASE/Python/epydoc.config).
(Changes relative to Release_April2007_1)
- operators and SparseIntVects. (issue 1716736)

- A preliminary implementation of the subshape alignment algorithm is available.
- The free version of MS Visual C++ is now supported.
- There is better support for queries in MDL mol files. (issue 1756962) Specifically: ring and chain bond queries; the not modifier for atom lists; R group labels.
- An EditableMol class is now exposed to Python to allow molecules to be easily edited. (issue 1764162)
- The RingInfo class is now exposed to Python.
- The replaceSidechains and and replaceCore functions have been added in the ChemTransforms library and are exposed to Python as Chem.ReplaceSidechains and Chem.ReplaceCore.
- pickle support added to classes: PointND
- atoms and bonds now support the HasQuery() and GetSmarts() methods from Python.
- Similarity scores can now be calculated from Python in bulk (i.e. calculating the similarity between one vector and a list of others). This can be substantially faster than calling the individual routines multiple times. The relevant functions are BulkTanimotoSimilarity, BulkDiceSimilarity, etc.
- The calculation of AtomPairs and TopologicalTorsions fingerprints is now a lot more efficient.
- Optimization of the Dice metric implementation for SparseIntVects
- The Visual Studio build files have been moved to the directories $RDBASE/Code/Build.VC71 and $RDBASE/Code/Build.VC80. This allows simultaneous support of both versions of the system and cleans up the source trees a bit.
- Boost version 1.34 is now supported (testing has been done on 1.34 and 1.34.1).
- Updates to the "Getting Started" documentation.
(Changes relative to Release_Jan2007_1)
- handing of isotope information in SMILES has been fixed
- "implicit" hydrogens are now added to charged atoms explicitly when writing SMILES. (issue 1670149)
- the 2D->3D code no longer generates non-planar conjugated 4-rings (e.g. C1=CC=C1). (issue 1653802)
- removing explicit hydrogens no longer produces incorrect smiles (issue 1694023)
- bit indices and signature lengths in the AtomPairs code no longer being calculated incorrectly. NOTE this changes the bits that are set, so if you have existing signatures, they will need to be regenerated.
- Fixed a bug causing MolSuppliers to generate incorrect length information when a combination of random access and iterator interfaces are used. (issue 1702647)
- Fixed a bug leading to incorrect line numbers in error messages from the SDMolSuppler. (issue 1695221)
- chemical reactions are now supported
- there is a new entry point into the 2D depictor code, compute2DCoordsMimicDistMat(), that attempts to generate 2D depictions that are similar to the structure described by the distance matrix. There's also a shorthand approach for calling this to mimic a 3D structure available as: AllChem.GenerateDepictionMatching3DStructure()
- DiscreteValueVect and UniformGrid3D now support the binary operators |, &, +, and -.
- a reader/writer for TPL files has been added.
- support has been added for MolCatalogs: hierarchical catalogs that can store complete molecules.
- the protrude distance metric for shapes has been added
- pickle support added to classes: UniformGrid, DiscreteValueVect, Point
- added the class DataStructs/SparseIntVect to improve performance and clarity of the AtomPairs code
- the non-GUI code now supports python2.5; the GUI code may work with python2.5, but that has not been tested
- the Mol and SD file parsers have been sped up quite a bit.
- the "Crippen" descriptors are now calculated somewhat faster.
- in-code documentation updates
- new documentation for beginners in $RDBASE/Docs/Book
(Changes relative to Release_Oct2006_1)
- zero-atom molecules now trigger an exception
- dummy atoms are no longer labelled 'Xe'
- core leak in the mol file writer fixed
- mol files with multiple charge lines are now correctly parsed
- a workaround was installed to prevent crashes in the regression tests on Windows when using the newest VC++ v7 series compiler. (http://sourceforge.net/tracker/index.php?func=detail&aid=1607290&group_id=160139&atid=814650)
- chirality perception (which requires partial sanitization) is no longer done by the MolFileParser when sanitization is switched off.
- Two potential memory corruption problems were fixed (rev's 150 and 151).
- optional use of chirality in substructure searches
- MolWriters can now all take a stream as an argument
- Chiral terms can now be included in the DistanceGeometry embedding.
- $RDBASE/Code/Demos/RDKit/BinaryIO is a demonstration of using boost IOStreams and the ROMol pickling mechanism to generate highly compressed, random-access files of molecules.
- the Point code has been refactored
