 **The changes made in the Version 0.5 and 0.51 updates are described in our recent FreeSolv update/mini-review paper in the [Journal of Chemical and Engineering Data](http://pubs.acs.org/doi/abs/10.1021/acs.jced.7b00104)**.
 
 ## Changes not yet in a formal release:
+- Remove redundant molecule mobley_4689084 (which duplicates  mobley_352111 had the same experimental value, and a calculated value within uncertainty) 
+- Add utility functionality to easily check for duplicates; rebuild database after removing above duplicate and checking for others
+- Update reference for calculated values to refer to the J Chem Engr Data reference.
