+### Update notes:
+##### BrkRaw v0.3.2
+
+1. Improved BIDS converter. 
+    - Bruker FieldMap will be accommodated into the BIDS excel sheets. With new feature, bids_converter separates fieldmap and magnitude image.  
+    - Multi-echo sequenced data will be converted as separate format.
+2. Bug patches.
+    - GUI visualization or crash issues related to certain conditions are patched.
+    - Matrix size instability has been patched, except multi-echo, all data will be converted to 3D + frame
+    - DTI slope correction issue is patched.

 #### Known issues
-- the last released version 0.3.1 does not convert DTI image correctly, please use 0.3.2 via github installation method.
-- The module have been tested for PV 5 to PV 6.0.1 datasets. but it may have issue with higher version.
-- The GUI may not work if the python does not be built with tkinter, please check above instruction.
-- If GUI popped up but not working after selecting the dir, make sure you entered to dataset dir.
-- If GUI cannot load zipped file, please check our example file located at 'examples' folder.
-- If you experience any other issue, please use 'issue' tab in Github to report.
-- The issues with lower priority.
-    - The GUI preview will show the image as matrix view not subject view and Magnitude dataset only.
+- The converter has not been tested the Paravision 360
+- Most of the GUI issues could be related to tkinter, please follow the above instruction first before open a issue.
+- Few update committed since the first stable version release, if you have any issue, please try the latest version.
+- For other unexpected issues, please use the issue channel.
+- There will be potential bug that occurred with new version updated, please let developer knows those issue by openning
+issue channel. Thank you for your contribution!
