Multi Value PS Query Works in v2, but not v3 or 4

Question

I have been using the query below (and others like it) for a few years, but it didn't work on v3, and now it doesn't work on v4--which is supposed to be backwards compatible.
Get-ADUser test01 –properties memberof, DisplayName, employeeID | Select-Object SamAccountName, DisplayName, employeeID, @{label="Groups";Expression={[string]::join(";", ($_.memberof))}} | export-csv -notype -force c:\filepath\filename.csv
I must invoke PS with the -version 2 suffix to run it.  Any ideas?
Thanks!

Hi,
Here's the adjustment I'd make:
Get-ADUser testac1 -Properties memberOf, DisplayName, employeeID |
Select-Object SamAccountName, DisplayName, employeeID, @{label="Groups";Expression={ ($_.memberOf | % { Get-ADGroup $_ }).Name -join ';' }} |
Export-Csv -NoTypeInformation -Force c:\filepath\filename.csv
EDIT: Another option:
Get-ADUser testac1 -Properties DisplayName, employeeID |
Select-Object SamAccountName, DisplayName, employeeID, @{N='Groups';E={(Get-ADPrincipalGroupMembership -Identity $_.SamAccountName).Name -join ';'}} |
Export-Csv -NoTypeInformation -Force c:\filepath\filename.csv
