[Gretl-users] Interval regression model

I was using gretl to do interval regression modeling using the function intreg. It was the gretl version 1.9.12 then. I was running the same analyses recently using the newer gretl version and found out that the intreg gives different coefficient estimates for the same data. I found out that I am getting different coefficient estimates since the gretl version 1.9.13. All upcoming versions of gretl (1.9.14 and 1.9.90) gives the same coefficient estimates as the gretl version 1.9.13. It seems that there have been some change in the algorithm for intreg at the version 1.9.13. However I do not see anything related to the intreg in the changelog (http://gretl.sourceforge.net/ChangeLog.html#v1-9-13). I am attaching the output files from the gretl 1.9.12 and 1.9.13 where you can see the differences in the coefficient estimates. Could you please explain briefly what has been changed for intreg at the gretl version 1.9.13?
