typo3 awstats extension after upgrade changes hash for the upload folder

Question

I am facing some problems with cc_awstats extension.

I have upgraded my site to typo3 4.5 from typo3 4.3 After upgrading, awstats file in uploads/tx_ccawstats has changed the hash generated and stored the new log data in newly generated folder.

Before upgrade: folder was "\uploads\tx_ccawstats\my_domain_f0ea6d30"

After upgrade: folder was "\uploads\tx_ccawstats\my_domain_db774c72"

OK, here i edit my question..

what might be the reason for hash change?

domain, logfile absolute path, log file name - these parameters are exactly same
