+0.19.0 (Wednesday 24th April 2019)
+----------------------------------
+
+
+Added
+^^^^^
+
+
+* The ``--column`` option now accepts a file which contains a list of column
+  names to import.
+
+
+Changed
+^^^^^^^
+
+
+* The :func:`.icd10.codeToNumeric` and :func:`.icd10.numericToCode` functions
+  have been changed to use the integer node IDs in the ICD10 hierarchy
+  file. The previous approach could not handle parent categories, nor a small
+  number of ICD10 codes which do not have a ``<letter><number>`` structure.
+* The :func:`.fileinfo.has_header` function has been made more lenient for
+  files with a small number of columns.
