-------- update 19dec2014 -------------------------------------------------------------------------------------------------

     1.  Online help and the search index have been brought up to date for Stata Journal 14(4).

     2.  forecast solve using estimates from arima with no covariates exited with an error message.  This has been fixed.

     3.  gsort, when arranging observations to be in descending order of a numeric variable, replaced the results in r()
         even though gsort is not an r-class command.  gsort now preserves existing results in r().

     4.  mfp would not allow abbreviated variable names to be entered in the options zero() and catzero().  This has been
         fixed.

     5.  total with option over() and without prefix svy sometimes failed to estimate the variance matrix and reported
         the warning "variance matrix is nonsymmetric or highly singular".  This most commonly occurred when over() was
         combined with vce(cluster clustvar).  This has been fixed.

     6.  tsreport, when used with data that included repeated time values and had not been either xtset or tsset with a
         panel variable, returned an uninformative error message.  This has been fixed.
