this is to inform you that unfortunately in the current release (gretl
2022a) a nasty bug crept in that makes it impossible to apply seasonal
adjustment with the (standard but external) X13-ARIMA procedure, at
least in the gretl GUI program -- that is, "normal" gretl with a window
and menus and so on.
Thanks to Ignacio for noticing and reporting this.!
The bug has already been fixed in the meantime, so current development
snapshots work as expected. But still it is quite regrettable, for
example because gretl 2022a was targeted at Ubuntu Linux 22.04, a
long-term support version, and so the bug will potentially have a long
An additional remark: One factor that led to the bug is that it is not
possible to test the GUI functionality in an automated way, in contrast
to what we can do for the scripts and commands. So that's where the
gretl user base comes in and is really needed! For example, right now
the next release will happen quite soon, so it would be very useful if
you can test the graphical gretl program more than you would do usually.
And then please report any bugs you find!
