Re: 5.4 application-version still required?
Coda: The application version IS still used in exception reports (both the
HTML version and, if memory servers, the new text file written to the file
system).

That is correct; tapestry.application-version is no longer needed. Each
individual asset gets its own content fingerprint. This has huge
implications for upgrades of you application, as often, all the unchanged
assets will maintain the same fingerprint, and already be present in the
end-user's browser cache.
