Latest firmware for Mediaflex 7811 and 7111

[g_ran_olofsson_]

Where can I find the latest firmware for my pair of Ruckus Mediaflex 7811/7111?
The ftp address in older answers in this forum doesn't work for me.

Goran do you still need this firmware? If so, please let me know at matt (@) dycom.com.au and I'll send you the version I have.

What are the changes between 5.3.3.0.21 and 5.3.3.0.24?

Now I also want to update my 7811 and 7111. But mentioned FTP-links are not working for me. Could somebody help to find the latest firmware?
