================= =================
This release brings planned reforms to our database schema that provide substantial If [`v1.1.0`](https://github.com/status-im/nimbus-eth2/releases/tag/v1.1.0)
performance improvements and pave the way for an an improved doppelganger detection was the big I/O update, `v1.2.0` is all about the CPU - together, these
ready immediately to propose and attest to blocks (in a future release). updates help secure Nimbus against future network growth, and provide us
with a higher security margin and substantial [profitability improvements]
(https://twitter.com/ethnimbus/status/1384071918723092486).
Please be aware that we will remain committed to maintaining backwards compatibility between To highlight just one data point, this release offers **up to 40% performance
releases, but **this release does not support downgrading back to any previous 1.0.x release**. improvements** over `v1.1.0` ( 🙏 batched attestation processing).
This makes it the first release we can officially recommend for validating
on a Raspberry Pi 4.
As a safety precaution, we advise you to **please backup your Nimbus database before upgrading** > **N.B.** this release contains a **critical stability fix** so please
if possible. **make sure you upgrade!**
**New features:** **New features:**
* More efficient state storage format ==> reduced I/O load and lower storage requirements. * 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:on` command-line flag
* More efficient in-memory cache for non-finalized states ==> significant reduction in memory * Batched attestation verification and other reforms **->** massive
usage. reduction in overall CPU usage.
* More efficient slashing database schema ==> scales better to a larger number of validators. * Improved attestation aggregation logic **->** denser aggregations
which in turn improve the overall health of the network and improve
block production.
* The metrics support is now compiled by default thanks to a new and more secure HTTP back-end. * More efficient LibP2P connection handling code **->** reduction in
overall memory usage.
* Command-line tools for generating testnet keystores and JSON deposit files suitable for use **We've fixed:**
with the official network launchpads.
* `setGraffiti` JSON-RPC call for modifying the graffiti bytes of the client at run-time. * A critical stability issue in attestation processing.
* `scripts/run-*-node.sh` no longer prompts for a web3 provider URL
when the `--web3-url` command-line option has already been specified.
