Geth 1.12.1 updated info

[Martin Holst Swende]

Hi list,

The 1.12.1 version released yesterday contains one bug which may cause
problems for users with extremely large leveldb databases -- that is,
archive nodes that have not resynched recently.

The issue is a "crash on startup", and is described here:
https://github.com/ethereum/go-ethereum/issues/27902

We have fixed the issue on the master branch, but have not yet made any
new release. For now, if you are running an archive node and have not
updated, then we advise you not to update to the new release. Either
wait for a new release, or use the latest master code.

If you have already upgraded and experienced no problem, then you should
be fine (until your database reaches the critical size).

Cheers,

The go-ethereum maintainers
