If v1.1.0 was the big I/O update, v1.2.0 is all about the CPU - together, these updates help secure Nimbus against future network growth, and provide us with a higher security margin and substantial profitability improvements.
To highlight just one data point, CPU usage has been cut by up to 50% over v1.1.0 ( 🙏 batched attestation processing). This makes it the first release we can officially recommend for validating on a Raspberry Pi 4.
N.B. this release contains a critical stability fix so please make sure you upgrade!
New features:
-
Beta support for the official Beacon Node REST API:
https://ethereum.github.io/eth2.0-APIs/. Enable it by launching the client with the--rest:oncommand-line flag -
Batched attestation verification and other reforms -> massive reduction in overall CPU usage.
-
Improved attestation aggregation logic -> denser aggregations which in turn improve the overall health of the network and improve block production.
-
More efficient LibP2P connection handling code -> reduction in overall memory usage.
We've fixed:
-
A critical stability issue in attestation processing.
-
scripts/run-*-node.shno longer prompts for a web3 provider URL when the--web3-urlcommand-line option has already been specified.
