2 days ago I had 548 filters and today 550.
How do I identify the 2 new ones?

I don't know either.
Hope someone more "inside" G'mic can answer.

best place to goto find out would be
GMIC Community

sallyanne, I think that here on GC some should know ....

@level_0
I posted your question on the GMIC Community as suggested by Sallyanne.
Let's see if I get the answer.

Maybe, but in that link I gave it is the same link as on the GMIC page and the people on that page who go there are the contributors to GMIC (some of them anyway)

First answer received:
"No, but the authors usually add the updated date in the description."

For some time I have thought too many filters, mostly appear in the testing section and most frequently from reptorian, afre, sometimes joan rake.

from 547 to 550 filters comparing updatexxx.gmic files.
The latest three are all reptorian: dynamic contrast / reverse engineer gradient map / reverse engineer color map

For info, the list of filters is here: https://gmic.eu/gui_filters.txt but it is the current list and unless you keep a record of old versions nothing to compare.

I received additional replies from G'mic experts, but the answer is still "no" (there is currently no way to ask about what is new after an internet update).

@level_0
good news, David T. (the "boss" of G'mic) is saying that it could be created a new filter to show what's new after an update.

Thank you all for your responses.





Thank you dinasset

...and David just did it!
Received :
New filter About / What’s New? has been added.
It will list the added and deleted filters from your last visit (to the filter).

I only see today that the problem is solved!
Thanks to dinasset and thanks to David Tschumperlé for his responsiveness!
