Comment (by mojca@…):

 I committed RC3 to my personal folder in r128087.

 Do we need `gnuplot-devel` perhaps? Here's a notice sent to the gnuplot
 mailing list (for me the nicest thing is "save to file" from wxt):

 {{{
 There is a source tarball on SourceForge for the 3rd (final) version 5.0
 release candidate.

 I do not expect much to change between -rc3  and the final 5.0 release,
 but if your valuable testing uncovers a problem there is still time to fix
 it.

 The user-visible changes since -rc2 are
 =============================

 - revised "fit" command
  + syntax:
        fit {<ranges>} <expression>
            '<datafile>' {datafile-modifiers}
            {{unitweights} | {y|xy|z}error | errors <var1>{,<var2>,...}}
            via '<parameter file>' | <var1>{,<var2>,...}
   + this is a CHANGE from -rc1 and -rc2
   + most version 4 "fit" syntax is detected and emulated even though
      the command options have changed. Also there is now an explicit
      command "set fit {v4|v5}" to force ambiguous commands to be
      interpreted as they were in version 4.

 - completion of time/date format changes begun in -rc1 and -rc2
  + formats used for input and output are now distinct
  + fime format used to read input data or range/position commands
     is specified by 'set timefmt' or  timecolumn(column,"timeformat')
  + timecolumn(column) uses default from 'set timefmt' as in version 4
  + time format used to output axis tic labels is specified by
     set {xyz}tics {timedate|geographic|numeric} format "..."
  + new format modifier "t" distinguishes a time interval from a date

 - wxt terminal has an Export-to-File widget on the toolbar

 - various bug fixes (see NEWS and ChangeLog)

 Known issues (no resolution expected before 5.0)
 ====================================

 - the wxt terminal emits runtime warnings and errors if gnuplot is
   built using wxWidgets 3.0 rather than 2.8
