Update on the 2.0.0 release & the full manual

We are getting close to the 2.0.0 stable release and the full manual. The manual will soon become available on the website and also in PDF format. Both versions will be identical and once released, will start to follow the APP release cycle and thus will stay up-to-date to the latest APP version.

Once 2.0.0 is released, the price for APP will increase. Owner's license holders will not need to pay an upgrade fee to use 2.0.0, neither do Renter's license holders.

Very nice signal, maybe a bit too dark in the background?

@vincent-mod
Thank you!

Hmm, this might be a screen cal/difference issue? I mean, it's not clipped for sure...
I still see the BG differences and features.

Sorry for the delay. Yes partly, if it's not clipped that is good indeed. I personally simply prefer a slightly brighter background, but it's a great result nonetheless!

Yes of course, we all have our creative differences 🙂
The lower part of the photo below the "wall" is always brighter, the upper part is always darker, since it's kind of "blocked out".

I wanted something a bit dramatic, since the wall is very emphasized, and bold... That's partly why I went for gentler tones, less saturation, since the structure itself was very pronounced already.

This is for example, an early "playing around" version:

Re-process, from stacking (with the new v2 beta), Ha-Oiii algorithm to Ha than Oiii

A brighter version, (@vincent-mod remembered you preferred it 🙂 )
