Ethereum (Go) - v1.12.2

Hot on the heels of v1.12.1 comes our next release, fixing some regressions reported by the community.

Here are the changes:

• A crash related to leveldb metrics is resolved (#27904)
• Metrics names used by the blobpool have been changed to be compatible with Prometheus (#27901)
• The c-kzg-4844 and blst libraries have been updated, hopefully fixing some build issues (#27890, #27907, #27910)
• We have also adapted go-ethereum to the latest changes in the 'slices' package provided by the golang.org/x/exp module. The Go authors decided to push an incompatible update, but didn't create a new release of that module, causing build issues when consumers mix-and-match dependency versions. (#27909)
• A note about the PPA: we are still working on resolving some build issues on Ubuntu 14.04 (Trusty) and Ubuntu 20.04 (Focal), packages might be missing for these Ubuntu versions.

For a full rundown of the changes please consult the Geth 1.12.2 release milestone.

As with all our previous releases, you can find the:

• Pre-built binaries for all platforms on our downloads page.
• Docker images published under ethereum/client-go.
• Ubuntu packages in our Launchpad PPA repository.
• OSX packages in our Homebrew Tap repository.
