Don't trust me?

Wireguard, I know it can be updated from the plugin itself but other images update it from the image itself, it's just for naming it, x-klass, x-streamity, bouquetmakerxtreme, ajpanel...
This are some I noticed but there might be more.
There are probably more than one thousand possible plugins for enigma2 which was the reason for asking about the plugin names.
Some of the plugins you mentioned are maintained by Kiddac. XStreamity was updated 3 days ago, or around 2 days when you started this thread. Here is the update from the source:
Add in vod default sort order, updated finnish translations
github.com
The last XStreamity update added in vod default sort order and updated finnish translations. I assume you speak and read Finnish?
Some other Plugins are here:

OpenATV and some other image groups have nightly builds. You will almost get instant updates with OpenATV image nightly builds, and you may also get instant bugs in the plugins and image because there has not been time to test these things.
Open Black Hole, OpenVix, and most other images update when there is enough changes to make an update worthwhile. Unless you are setup for automatic build, someone has to build the images and the feeds, then upload these things to the internet so your receiver can get them.
So if you want the latest and the greatest plugins along with any bugs they may have, go for the OpenATV nightly build. Sure there can be bugs and errors in OBH, but allowing for a little time after something has been updated also allows a little time to see how the updates perform.
He who updates the most in enigma2 has the most problems. If things are running good, don't worry about updating. And if you don't know why you are updating, then you probably shouldn't. The Finnish language update shown above is a common example. The Finnish update is great if you speak that language, but mostly useless to others that don't.
