It fixes the overflow issue by switching the tracked values that are in danger of overflowing from `CAmount` to `arith_uint256`. The current approach opts for a simple solution to ensure compatibility with datadirs including the previous version of the index: The new version of the index goes into a separate location in the datadir (`index/coinstatsindex/` rather than `index/coinstats/` before, the new naming is more consistent with the naming of the other indexes). There is no explicit concept of versioning of the index which earlier versions of this PR had. Having the two different versions of the index in separate places allows for downgrading of the node without having to rebuild the index. However, there will be a warning printed in the logs if the new code (v30) detects the old index still being present. A future version could delete a left-over legacy index automatically. The PR also includes several minor improvements but most notably it lets new entries be calculated and stored without needing to read any DB records.

Bitcoin Core
Setup
Bitcoin Core is the original Bitcoin client and it builds the backbone of the network. It downloads and, by default, stores the entire history of Bitcoin transactions, which requires several hundred gigabytes or more of disk space. Depending on the speed of your computer and network connection, the synchronization process can take anywhere from a few hours to several days or more.
To download Bitcoin Core, visit bitcoincore.org.
Running
The following are some helpful notes on how to run Bitcoin Core on your native platform.
Unix
Unpack the files into a directory and run:
bin/bitcoin-qt(GUI) orbin/bitcoind(headless)bin/bitcoin(wrapper command)
The bitcoin command supports subcommands like bitcoin gui, bitcoin node, and bitcoin rpc exposing different functionality. Subcommands can be listed with bitcoin help.
Windows
Unpack the files into a directory, and then run bitcoin-qt.exe.
macOS
Drag Bitcoin Core to your applications folder, and then run Bitcoin Core.
