[Gimp-developer] does the current git master have 16/32-bit color channels and non-destructive editing?

[kcleung users sourceforge net]

I am new to gimp, and the website says that gimp 2.10 will use 16/32-bit
channels.  However does the current git master also have 16/32-bit
channels?  Also does the git master support non-destructive editing?

I have an important photo post-processing job, and I will use gimp for this
job only if it uses 16/32-bit channels.

Thanks!
