More changes are needed, see here for example: https://github.com/PowerShell/PSScriptAnalyzer/pull/1965/files
I always to search replace and just make sure to exclude CHANGELOG.MD: https://github.com/PowerShell/PSScriptAnalyzer/blob/master/CHANGELOG.MD

@bergmeister as an aside perhaps it's worth having a test to check the version number is updated in all the right places, so that in future this isn't missed

That or build a script that will replace it across all those files based on what GitVersion outputs for the next version, as that would allow this to be caught in local builds as well as hosted pipeline builds too
