- New feature: offer a choice of plotting styles or themes,
via GUI and also via a new "set" variable, graph_theme;
plus set the default to the "dark2" theme
- Add new bincoeff() function, giving binomial coefficients
- Add new sgn() function: returns the sign of its argument
- Improve error message in case of invalid gnuplot path
- loop: make "quiet" operation the default
- Path-searching for inputs: improve the mechanism for
storing likely locations based on the opening of scripts
- Packaged datasets: show type and size in the GUI, as well
as a brief description
- GUI data access: add convenience menu items for accessing
files supplied by "addons" such as SVAR
- bwrite() and bread() functions: support JSON as well as
XML for representing gretl bundles
- atof() function: allow giving a string-valued series as
argument
- strlen() function: generalize to allow strings array and
string-valued series arguments
- pshrink() function: add an optional argument to avoid
skipping missing values
- mshape() function: make the third argument optional and
document the new behavior
- Fix bug: failure of negative matrix index (exclusion)
when a value of -999 was given
- Fix bug: the "restrict" command as applied to VECMs could
emit an unwanted newline even given the --silent option
- Fix bug: "panel plot" coud crash under certain conditions
- Fix bug: ensure greater precision when printing values
to 15 or more significant digits
- Fix bug: possible error in Spearman's rho for the case of
no ties
- "fractint" and "hurst" commands: make the estimated
fractional difference or exponent accessible via the
$result accessor
- "xtab" command: fix for the case when one or more of the
series to be cross-tabulated are string-valued
- "summary" command: don't provide spurious results for
string-values series
- "scatters" command, time-series variant: try harder to get
appropriate time-axis tics
- "pkg" command: enable variant "pkg index addons" to update
the index of installed "addon" packages
- "set" command, "initvals" keyword: clarify the status of
this setting (non-persistent)
- String-valued series: drop any unused strings when sub-
sampling with the --permanent flag, and when saving a
sub-sampled dataset via the "store" command
- Arrays of strings: support union and intersection via the
"||" and "&&" operators respectively
- Error reporting: be more specific when the problem is an
out-of-bounds index value
- Datasets supplied with gretl: include a version of R's
"swisspharma" data; enhance the grunfeld panel dataset
- User's Guide: incorporate the previously stand-alone MIDAS
documentation as two new Guide chapters
- MS Windows and macOS builds: update to gnuplot 5.2.6
