Effects of newer version of MDK-ARM compiler onto firmware already in production (beginner’s question)

I was tasked with overseeing and potentially, maintenance of a firmware package (LPC1788 and LPC2478) built with MDK-ARM 5.10. I noticed that the latest version is 5.34 of March 15, 2021:

Q1: Is there any problem to use the latest MDK-ARM? Where can I read more about it?


Q2: MDK-ARM 5.10 still available for download?

Thank you,

Eugene L.
