 ## [2.0.0] - 2019-08-08
+### Changed
+- python library: split class `SubfieldVolumeFile` from `VolumeFile`
+
+### Added
+- python library: class `ashs.IntracranialVolumeFile`
+- examples:
+  - added ASHS
+  - added comparison FreeSurfer vs. ASHS
+
+### Fixed
+* install: no longer require runtime dependencies to run `setup.py`
 
 ## [1.0.0] - 2019-05-05
+### Changed
+- console entry point `freesurfer-volume-reader`:
+  - exit with code `EX_NOINPUT`/`66` in case no matching volume files were found
+    (previously: exception with exit code `1`)
+  - renamed param `--filename-regex` to `--freesurfer-hipposf-filename-regex`
+- python library:
+  - renamed `read_hippocampal_volume_file_dataframe()`
+    to `freesurfer.HippocampalSubfieldsVolumeFile.read_volumes_dataframe()`
+  - renamed `read_hippocampal_volumes_mm3()`
+    to `freesurfer.HippocampalSubfieldsVolumeFile.read_volumes_mm3()`
+  - renamed `parse_hippocampal_volume_file_path()`
+    to `freesurfer.HippocampalSubfieldsVolumeFile.__init__()`
+  - renamed `find_hippocampal_volume_files()`
+    to `freesurfer.FreesurferHippocampalVolumeFile.find()`
+
+### Added
+- console entry point `freesurfer-volume-reader`:
+  - flag `--version` to show version
+  - param `--source-types` to optionally enable collection of ASHS `*volumes.txt` files
+    (default: freesurfer only)
+  - param `--ashs-filename-regex`
+- python library: added class `ashs.HippocampalSubfieldsVolumeFile`
+  to find & read ASHS *volumes.txt files
 
 ## [0.2.1] - 2019-04-28
+### Fixed
+- added pandas version constraint (required for `pandas.DataFrame.drop`)
 
 ## [0.2.0] - 2019-04-28

+
+### Fixed
+- invalid root path when `$SUBJECTS_DIR` is set and root dir path is provided as positional arg
 
 ## [0.1.1] - 2019-04-27
+### Fixed
+- test `read_hippocampal_volume_file_dataframe` on python3.5
 
 ## [0.1.0] - 2019-04-26
+### Added
+- script `freesurfer-volume-reader`:
+  - recursively collect Freesurfer's hippocampal subfield volume files
+  - output in CSV-format
+- python module `freesurfer_volume_reader`
