Private Last Mile checks for new versions of itself every 120 minutes (2 hours), in a two-step process.
The peer downloads a small text file from
http://220.127.116.11/p3/kernel/version.xmlthat contains checksums of the latest versions of each file in the peer's installation tree.
Any files that differ from the checksum contained in the file are fetched from the same Web server.
In most cases, Private Last Mile automatically restarts following a version update in order to load the new files.
