Version not Specific enough?

[tommck]

When I try to follow the directions in the ReadMe, I get this when reopening VS Code:

C:/Users/tom/.vscode/extensions/ino: Version specified in engines.vscode (*) is not specific enough. For vscode versions before 1.0.0, please define at a minimum the major and minor desired version. E.g. ^0.10.0, 0.10.x, 0.11.0, etc.

Latest VS Code, Windows 10

It's the same with me on Linux Mint. When I type ^0.10.11 as suggeseted, syntax highlighting is gone but the issue is not displayed anymore.
