 # Changes
 
+## 1.5 (2017-01-24)
+
+* allow arbitrary non-string data as input
+* dropped support of EOL Python versions (2.6, 3.2 and 3.3)
+* fixed a possible division-by-zero exception
+* fixed a formatting error in an exception message
+
 ## 1.4.1 (2016-07-18)
 * Clarified that this implementation is of the [optimal string alignment distance algorithm](https://en.wikipedia.org/wiki/Damerau%E2%80%93Levenshtein_distance#Optimal_string_alignment_distance) (see [this issue](https://github.com/gfairchild/pyxDamerauLevenshtein/issues/6) for more information).
 * Renamed `damerau_levenshtein_distance_withNPArray` to `damerau_levenshtein_distance_ndarray` and `normalized_damerau_levenshtein_distance_withNPArray` to `normalized_damerau_levenshtein_distance_ndarray`.

 This implementation is based on [Michael Homer's pure Python implementation](https://web.archive.org/web/20150909134357/http://mwh.geek.nz:80/2009/04/26/python-damerau-levenshtein-distance/), which implements the [optimal string alignment distance algorithm](https://en.wikipedia.org/wiki/Damerau%E2%80%93Levenshtein_distance#Optimal_string_alignment_distance). It runs in `O(N*M)` time using `O(M)` space. It supports unicode characters.
 
 ## REQUIREMENTS
-This code requires Python 2.6, 2.7 or Python 3.4+, [NumPy](http://www.numpy.org/), and a C compiler such as GCC. Although the code was written in Cython, Cython is not required for installation.
