I don't know how good we are at finding the next Mersenne Prime, but we're sure good at keeping you on your toes...

In the email the server sends if a computer is late contacting GIMPS, there is no space between "than" and the number of hours: e.g. "Your computer named foo is more than25 hours late reporting to the GIMPS server."

Server declares the absence of a reported proof is because of old software, even when the result is from a proof-capable software version. (Server is apparently ignoring the possibilities of user error such as failing to upload the proof file generated, or because of lengthy loss of connection to a network share, prime95 filling emergency memory and then losing necessary temporaries, or gpuowl having an error such as a checksum failure, such that it ceases to save needed temporaries to the local hard drive.)
Example: https://www.mersenne.org/report_expo...=1&swversion=1 gpuowl v6.11-380 is definitely proof-capable (as is -318 or above), but a combination of errors occurred such that past ~33%, temporaries were not saved. In this case it was not disk space issue, but some sort of execution issue. The last temporary saved in this case was at iteration 42506688, ~32.81%, so not enough to salvage a proof power of one or higher.

(In V6.11-380 and similar, there is a slight iteration count numbering difference versus proof power, such that a power 10 run saves iteration 506032 in the example run, while validation of power 8 seeks 506031, so fallback to 8 on a power 10 run fails. IIRC that was corrected in v7.x)

Second example, prime95 v30.8b14: 480000107
Occasionally in prime.log:
Code:
DOSerrno: 53

The criteria for "PRP without proof (old software)" is whether or not the JSON result contains the "proof" section. This message does not differentiate between "PRP software didn't generate a proof because it doesn't know how to" vs "PRP software didn't generate a proof because of some error on the user's system". What it is differentiating between is "PRP without proof because it wasn't uploaded" vs "PRP without proof because it wasn't generated".

So, perhaps it should say proof not generated, instead of claiming the sometimes-wrong "old software". Or better yet distinguish between them, but that would require more conditionals, on software-specific version thresholds.
There have been a tremendous number of improvements recently in server web page outputs and options. This is one more opportunity to better inform the users. As it stands, it is sometimes MISinforming the users.
