<commit_before>******  Release_XXX2007_1 *******
(Changes relative to Release_Aug2007_1)

Bug Fixes
 - the Recap code no longer generates illegal fragments for
   highly-branched atoms. (issue 1801871)
 
New Features
 - The SparseIntVect class (used by the atom pairs and topological
   torsions) is now implemented in C++.
   
Other
 - The full set of tests is now easier to setup and run on new
   machines. (issue 1757265) 


******  Release_Aug2007_1 *******
(Changes relative to Release_April2007_1)

Bug Fixes
 - operators and SparseIntVects. (issue 1716736)
 - the Mol file parser now calculates cis/trans labels for double
   bonds where the two ends had the same substituents. (issue 1718794)
 - iterator interface to DiscreteValueVects and UniformGrid3D. (issue
   1719831)
 - improper removal of stereochemistry from ring atoms (issue
   1719053)
 - stereochemistry specifications and ring bonds.  (issue 1725068)
 - handling of aromatic bonds in template molecules for chemical
   reactions. (issue 1748846)
 - handling of unrecognized atom types in the descriptor calculation
   code. (issue 1749494)
 - ChemicalReactionException now exposed to Python. (issue 1749513)
 - some small problems in topological torsions and atom pairs

New Features
 - The Atom Pairs and Topological Torsions code can now provide
   "explanations" of the codes. See $RDBASE/Python/Chem/AtomPairs for
   details.
 - The PointND class has been exposed to Python
 - The "Butina" clustering algorithm [JCICS 39:747-50 (1999)] is now<commit_msg>try to keep this up to date<commit_after>******  Release_XXX2007_1 *******

Bug Fixes
 - 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)
 
New Features
 - 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.
 - 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.

Other
 - The full set of tests is now easier to setup and run on new
   machines. (issue 1757265)
