v0.3, (April 2021)

I also know that some people are waiting for an update of the
"cointARDL" package. Quick fixes for it should come, hopefully, at the
end of the week.
Also, you always can get an overview of recent updates of packages either
(1) here
http://ricardo.ecn.wfu.edu/gretl/cgi-bin/gretldata.cgi?opt=SHOW_FUNCS
or (2) via the GUI: File -> Function packages -> On server... -> Sort
the packages by Date.
Best,
