Dear all,
happy new year to everybody!
Now that the year 2022 is over, just a small piece of trivial 
information: There are 48 contributed function packages that have been 
updated during the last year - although it has to be said that in many 
cases the updates consisted of smaller syntax adjustments.
This number doesn't include the so-called "addons": those are also 
function packages written in the hansl scripting language (like the 
contributed packages), but they are more tightly integrated into the 
gretl infrastructure and are automatically shipped with each gretl 
install. Currently there are 10 addons (see Help / look for addons), 
half of which have been updated during 2022. For comparison, there are 
155 contributed packages in total.
We would like to encourage everybody to get in the business of authoring 
and contributing function packages. The scripting language hansl is easy 
to learn, but powerful. And in general gretl offers documentation that 
is quite comprehensive: See Help / A Hansl Primer for an introduction to 
the language (in combination with the general gretl user guide, of 
course), and Help / Gretl Function Packaging Guide.
Every package version has to go through a moderation process, where we 
as the moderation team make sure that (a) the package actually runs and 
works, and (b) has at least a minimal amount of documentation. 
Especially for first-time contributors, we're happy to help with 
problems and provide some hints. However, the package authors obviously 
remain responsible for what their code does and what results it 
produces. (Apart from the obvious fact that like any GPL'ed free / open 
source software, neither gretl itself nor the contributed packages come 
with any kind of warranties.)
cheers
