Unfortunately, this is a little confusing to me.
On the download page, Wine 5.17 is marked as the development release. However, when I initially downloaded it via my package manager (pamac), it downloaded version 5.16 (latest development version at the time.)
The package manager did not say anything about it being a development version. But on their website, 5.0.2 is listed as the stable version.
Pyxel Edit works in 5.17 now though :)
I think that 5.0.2 should be considered the "Slow" release channel, and 5.17 should be a "Rolling Release".
My distro (Manjaro Linux) is considered a rolling release distro, so this would make sense.
