"Upload certificates" are a mechanism that keeps bad guys from DoS'ing your upload servers (note: such an attack has never happened, as far as I know).

We're changing the format of upload certificates, and we're starting to test a version of the client for which old-format certificates won't work. Volunteers testers won't be able to upload completed jobs, and they may complain to you.

I suggest that all projects disable upload certificates. To do so, add the following to your config.xml file:

<dont_generate_upload_certificates/>
<ignore_upload_certificates/>

To resume using upload certificates, if you wish:

1) upgrade to the current server source code (from trunk)
2) wait for all jobs with old-format certificates to be dispatched
3) re-enable certificates by removing the above lines.

Let me know if any questions.
