[ANN] U-Boot v2024.04-rc3 released

Hey all,

It's late in the day, but still release day and so here's -rc3. I've also pushed this to the next branch and that is now open.

In terms of a changelog, git log --merges v2024.04-rc2..v2024.04-rc3 contains what I've pulled but as always, better PR messages and tags will provide better results here.

I hope to get back on schedule and that means the rest of the rcs every other Monday, and with final release on Tuesday, April 2nd, 2024. Thanks all!
