The latest (final?) #CLN release candidate fixes a long-standing bug where we could forget UTXO spends when we restart. This explains a variety of bug reports we have seen and been unable to reproduce over the years: the most recurrent being gossipd telling peers about channels which are long closed.
We no longer make this mistake, but we also have to walk back and revisit old UTXOs. We do this while running, but for older nodes (like mine!) that can be a lot of blocks. In fact, and I only vaguely recall this, my node tracks back to block 500 (!) so it's going to take a while.
Of course we remember progress, so you can restart slike normal during this process. Other than higher CPU consumption you shouldn't notice anything.
