It depends. Regarding smaller details (like a removed sticker, windows layout modification or some trace of jetways, gone painting on fuselage and wings…) yes, I will usually apply these changes when they happen.
For exemple, I am planing to get the AV400 F-GZNE. From the preview picture, I have noticed they kept 2025 state of this reg, with the 2014 La Première 4 windows (by referring to the latest pictures of F-GZNE until 2025). However this aircraft received the new config in 2026 (1 or 2 months ago) so I will have to modify the windows layout myself (5 windows for the new La Première)
This how it looked like until 2025 (previous config):

And this is how it looks like now (new config):

I might wait before taking the decision of modifying the layout or not. I still don’t know if I will prefer matching its current state or if I will prefer keeping the 2014 configuration which is being replaced. NG potentially releasing a four class AF77W might influence my decision on this.
