Hi, I just pushed version v5020 to github (https://github.com/RIPE-NCC/ripe-atlas-software-probe/tree/v5020) The main change is to the 'SOS' mechanism. Probes look up a special DNS name just before they try to connect. This can be used to diagnose probes that have trouble connecting. For hardware probes we rely on the probe's ethernet address to distinguish between probes. For software probes that doesn't work because we don't record ethernet addresses for software probes. We made a change to have software probes send the hash of the probe's public key instead. With this change the network tab of the probe page shows the 'SOS History'.
From this release we now also support CentOS 8 binary packages, though I noticed that we did not yet add that to the installation instructions.
Finally, we changed the way we accept SSH public keys. We now accepts longer RSA keys (max. 4096 bits) as well as ECDSA and ED25519 Philip Homburg
