Verifying LinuxCNC ISO download.

I am just getting started and have been working through the excellent series of videos by Joe Hildreth.  These videos are now 6 years old and so I think things may have moved on.  When it comes to downloading the latest version from the Downloads page, Joe recommends checking the download with a check sum using md5sum or sha256sum.  On the video the checksum is on the download page, as is a link to zsync - the method of downloading he recommends.  This is not on the current downloads page.  Do I still need to check my download (to a flash drive) before i install it on my new control computer?  If this has been covered elsewhere I am sorry but I have tried searching and cannot find an answer.

The cheksum I get with sha256sum linuxcnc_2.9.4-amd64.hybrid.iso is:

ef0d0cc7142444d8793233e516105f0c9f3dee667cfede1539e2190b39a29060  linuxcnc_2.9.4-amd64.hybrid.iso

Which does not match the checksum listed on the getting linuxcnc page which is given as:
I have done several dowloads and thus far none of the checksums have matched.

zsync is listed as an alternative on the getting linuxcnc page.  It does  not find a control file that it wants on the server and it will not download linuxcnc_2.9.4-amd64.hybrid.iso.

I share your frustration.

Just give it a go,
I get
ef0d0cc7142444d8793233e516105f0c9f3dee667cfede1539e2190b39a29060

and all seems fine.

I woud not mind betting the checksum was never updated on the last release. I am sure checksums are unecessary today.
As said, just use it!
