status-im/nimbus-eth2 v22.4.0

on GitHub

Notes

Nimbus v22.4.0 is a low-urgency upgrade which contains numerous fixes, optimisations, and a better user experience around trusted node sync. It lays the foundations for upcoming the merge hard-fork which will be fully supported in our next release (v22.5.0).

Improved:

• All CPU cores are now used by default: this was previously enabled by passing --num-threads:0 on the command-line
  #3493

• 250 MB reduction in memory usage: thanks to more efficient data structures for the finalized portion of the chain history
  #3513

• Higher performance historic queries (using REST API) after trusted node sync: Nimbus now re-indexes the backfilled chain of blocks
  #3452

• Broadcasted attestations are more likely to be included in blocks by other nodes: thanks to a tweak to the attestation sending time
  #3518

• The REST API now only returns current and relevant information in response to VC queries: in other words, information from the recent non-finalized portion of the chain history
  #3538

• Better and more consistent gossip mesh health: the --max-peers option now works as a target that can be exceeded by the client temporarily in order to maintain good gossip mesh health; the newly introduced --hard-max-peers option now acts as the hard limit that should not be exceeded (default set to max-peers * 1.5)
  #3346

• An ERA files developer preview: ERA files are an ultra-efficient long-term storage format for finalized chain history

Fixed:

• Nimbus no longer crashes when a HTTP URL is specified as a --web3-url end-point:
  #3582

• The REST end-point /eth/v1/beacon/headers is now able to return backfilled blocks:
  #3472

• The Nimbus status bar has been disabled on Windows in order to avoid sporadic hangs in certain terminal emulators:
  #3484

• A large start-up delay after backfilling:
  #3516

• A rare problem which prevented the node from starting successfully after a trusted node sync:
  #3517

• Confusing error messages when Nimbus lacks the necessary file system permissions to create its database:
  #3536

Removed:

• The support for the Pyrmont testnet has been removed in order to reduce the Nimbus binary size:
  #3568

Urgency guidelines

low-urgency: update at your own convenience, sometime within our normal update cycle of two weeks

medium-urgency: may contain an important stability fix, it is better to update sooner rather than later

high-urgency: update as soon as you can, this is a critical update required for Nimbus to function correctly

Binaries

Scroll to the bottom of this release and click on the tar.gz which corresponds to your OS and architecture: unpack the archive, read the README and run the binary directly (or through one of our provided wrapper scripts).

We've designed the build process to be reproducible. In practice, this means that anyone can verify that these exact binaries were produced from the corresponding source code commits. For more about the philosophy and importance of this feature see reproducible-builds.org.

For instructions on how to reproduce the build, see the included "README.md" file. See pre-built binaries documentation for more.
