 Changelog/News
 --------------
 
+**Version 3.0.0.0 - 08/03/2018**
+
+- UPGRADE: upgrade the xcms version from 1.46.0 to 3.0.0. So refactoring of a lot of underlining codes and methods
+
+- IMPROVMENT: a new dedicated tool "xcms plot chromatogram" will allow you to get TIC and BPI of your raw data.
+
+- IMPROVMENT: the tool will now generate a sampleMetadata file if any was provided. It will be useful to add some further information for the normalization and statistics steps.
+
 **Version 1.0.1 - 13/02/2017**
 
 - IMPROVMENT: the tool will now raise an error if a sample isn't describe in the sampleMetadata file

+
+    | Ions' identifiers are constructed as MxxxTyyy where 'xxx' is the ion median mass and 'yyy' the ion median retention time.

+    | Theses parameters do not affect decimal places in columns other than the identifier one.
+
+**Reported intensity values**
+
+    | This parameter determines which values should be reported as intensities in the dataMatrix table; it correspond to xcms 'intval' parameter:
+    | - into: integrated area of original (raw) peak

 Changelog/News
 --------------
 
+**Version 3.0.0.0 - 08/03/2018**
+
+- UPGRADE: upgrade the xcms version from 1.46.0 to 3.0.0. So refactoring of a lot of underlining codes and methods
+
+- IMPROVMENT: a new dedicated tool "xcms plot chromatogram" will allow you to get TIC and BPI of your raw data.
+
+- IMPROVMENT: the tool will now generate a sampleMetadata file if any was provided. It will be useful to add some further information for the normalization and statistics steps.
+
 **Version 1.0.1 - 13/02/2017**
 
 - IMPROVMENT: the tool will now raise an error if a sample isn't describe in the sampleMetadata file
 
-
 **Version 1.0.0 - 03/02/2017**
 
 - NEW: a new tool to merge individual xcmsSet outputs to be used by xcms.group
