# profileVersion

The version of the profile format.

## Declaration

```occ
UInt32 profileVersion;
```

## Discussion

 The first 8 bits indicate the major version number, followed by 8 bits indicating the minor version number. The following 2 bytes are reserved.

The profile version number is not tied to the version of the ColorSync Manager. Profile formats and their versions are defined by the ICC. For example, a major version change may indicate the addition of new required tags to the profile format; a minor version change may indicate the addition of new optional tags.
