 # version
 
-`version`, while related to the app’s own versioning, doesn’t have to follow it exactly. It is common to change it slightly so it can be [interpolated](https://en.wikipedia.org/wiki/String_interpolation#Ruby) in other stanzas, usually in `url` to create a Cask that only needs `version` and `sha256` changes when updated. This can be taken further, when needed, with [ruby String methods](https://ruby-doc.org/core/String.html).

+The special value `:latest` is used on casks which:
+
+1. `url` doesn’t contain a version.
+2. Having a correct value to `version` is too difficult or impractical, even with our automated systems.

 ## version methods
 
 The examples above can become hard to read, however. Since many of these changes are common, we provide a number of helpers to clearly interpret otherwise obtuse cases:
