From this page you can follow a trail all the way back to 0.00 if you're so inclined:

Okay, maybe not. A number of the oldest versions aren't available. Anyway, there's also:

This is problem with Powershell. (May by need to create bugreport ?)

This example runs fine from CMD (but i recommend FAR for conveniety) and fails from PS.

Tested Win10.1909, dmd 2.095

Then you could keep the old documentation around for the old version, and create new documentation for the new version and no matter which version someone is using they would have documentation (within limits.)

The website is *supposed* to keep documentation for old versions around, and allow you to select them using the drop-down menu at the top-right:

However, it looks like this feature is currently broken, since the archived documentation stops at version 2.081. I've filed an issue in the appropriate repository [1], so hopefully that will be fixed soon.

note that in some cases my website lets you pull old versions too:

http://phobos.dpldocs.info/v2.068.0/

for example. But since I rarely use old versions it probably won't be in cache and thus you have to wait for the slow process of it downloading and generating the files.

The file never includes the quote marks for some reason, I've tried a few different ways although I haven't been able to figure out why yet. The documentation for powershell says it should work. This undocumented feature works though:

PS> rdmd --eval='writeln(format!`"%b`"(78));'

Thanks, I bookmarked this.
