With the release of Volta 1.1.0, the get.volta.sh installer only works for that version, due to the change in release artifacts.
We have a section in our docs about installing old versions, from the last time we had a breaking change in the install script (Volta 0.7.0).
However, Volta 0.7.0 is 2.5 years old now (Volta 1.0.0 itself is almost 2 years old!) and far from supported.
Rather than adding an extra section and trying to explain to use script A for Volta < 0.7.0 and script B for Volta between 0.7.0 and 1.1.0, we can likely drop the reference to the 0.6.8 installer entirely.
Changes
Updated the minimum supported Volta version for the default installer in the Installing Old Versions
Update the code sample to use the appropriate 1.0 installer and example version
