Thanks for the suggestion.
You are right that this skin does not require the latest version to work, and I usually do set required versions based on the requirements of the skin, but in this case, I just used the default version of Rainmeter set by the packager.
Since it is an update of another author's creation, I will not be posting it anywhere else for distribution to the masses.
I may change the requirement level to an earlier version, but we no longer offer beta
releases and using the latest version of Rainmeter is what I recommend.
It may reduce who can install it using skininstaller.exe, but it can always be manually extracted and copied to SKINS, or it may prompt people to update to the latest version of Rainmeter. Any of those are not necessarily bad, so it may just remain as it is for now.
