Latest software/firmware for SG500X-48 Stackable Managed Switch

[dsnyder14]

I have inherited an SG500X-48 with the following:

Unit 1(Master): SG500X-48 48-Port Gigabit with 4-Port 10-Gigabit Stackable Managed Switch

Software Information
Firmware Version (Active Image): 1.4.2.4
Firmware Version (Non-active): 1.4.2.4
Boot Version: 1.4.0.02
Locale: en-US
Language Version: 1.4.2.4

What is (was) the latest firmware and boot software available for this switch?

Where can I get it?

Thanks

Since its product EoL, you won't be able to see any new software to download :

I figured.  I'm pretty sure this has never been updated in however long it's been in use.  I was just hoping to bring it up to the latest that was available before it EOL'd.

You'd think there'd be an archive somewhere......

Thanks!
