• Fix for bug #21754, the failure of the grace.view user function on MS Windows in opening a file in qtgrace when the path includes spaces, as reported by Mengjun Xue (mengjun dott xue att mailbox dott tu-berlin dott de). The fix was to run the program with the file name in double quotes.
• Fix for bug #21763, the problem of the chi2 value not being visible in the parameter list of the grace.write and value.write user functions in the GUI. The problem was that when asking for the parameter name list, the minimisation parameters were not being asked for.
