1) perhaps there was an old link to a previous webpage left on the help pages, as I assure you I can tell the difference between a 5.6 and 6.7 especially when I specifically checked those versions. However now too busy to check caches as it appears I need to update the OS on scores of servers.
2) Both mathLM and Mathematica v10.2 dated late 2015 do run on centos 5, and I am running both, which is why I have been caught out with the minor upgrade to 10.3. which doesn't.
3) In paces such as Universities with thousands of users, all of whom like to run software on their laptops, with OS' s dating back to win2000 up to win10, macos leopard to El capitan, solaris, Irix, scores of different linux flavous, compatibility changes are a real nightmare. They are far far more important than the latest new functionality that wolfram email us about on weekly basis. As the sysadmin for apps like maple, matlab etc I know they at least provide patches for these issues --as matlab have done for El capitan. So if anyone from Wolfram reads this --- make sure you draw attention to compatibility issues, especially if no longer supporting an OS with as much notice as possible. (plus a specific email to all site licence holders, with subject line "OS compatibility" ).
Then at least I can point these issues out to users and keep a copy of old versions.
- How about providing a statically linked version of mathinfo as that appears to be the issue at least with MathLM script.
