[Gretl-users] Seasonal adjustment: Use of X13 in the GUI program has been restored

Hi everybody, 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 life there. 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! thanks sven
