The changes to the variable innodb_purge_threads was made in the same revision -- https://bazaar.launchpad.net/~percona-core/percona-server/5.5/revision/234.1.13

The only changes to purge it seems to have done are to make
purges less aggressive (by introducing os_thread_sleep) and
waking up the purge irrespective of batch size.

However, it was a bulk import (not broken into logical patches),
so it has changes to adaptive flushing and log flushing, since
purge thread also syncs log buffer, it has effect.

Changing the default won't break it, but many seemed to have assumed it to be 1 in PS (because of all those changes), so we should make it clear in release notes if we change it.
