Bamboo Build Number Stamper plugin available for Bamboo 6.4?

[Tom Allen]

I'm preparing to upgrade from Bamboo 5.10 to 6.4. We use the Bamboo Build Number Stamper add-on to programmatically purge our build working directories whenever the most recent build is older than a week. We do this by examining the create date of the build-number.txt file.

This add-on's Version History in the Marketplace indicates is runs under Bamboo Server versions 5.0 to 5.14.5. Does anyone know if this add-on is compatible with Bamboo 6.4?
