2022-03-12 v22.4.0
==================
Nimbus `v22.4.0` is a `low-urgency` upgrade which brings with it further optimisations, and better user experience around [trusted node sync](https://nimbus.guide/trusted-node-sync.html). It lays the foundations for upcoming the merge hard-fork which will be fully supported in our next release (`v22.5.0`).
### Improvements:
* All CPU cores are now used by default: previously enabled by passing `--threads:0` on the command-line
https://github.com/status-im/nimbus-eth2/pull/3493
* 250 MB reduction in memory usage: thanks to more efficient data structures for the finalized portion of the chain history
https://github.com/status-im/nimbus-eth2/pull/3513
* Higher performance historic queries (using REST API) after trusted node sync: Nimbus now re-indexes the backfilled chain of blocks
https://github.com/status-im/nimbus-eth2/pull/3452
* Broadcasted attestations are more likely to be included in blocks by other nodes: thanks to a tweak to the attestation sending time
https://github.com/status-im/nimbus-eth2/pull/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
https://github.com/status-im/nimbus-eth2/pull/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`)
https://github.com/status-im/nimbus-eth2/pull/3346
* An [ERA files](https://our.status.im/nimbus-update-march/#era-files-a-proposed-solution-to-historical-data-queries) developer preview: ERA files are an ultra-efficient long-term storage format for finalized chain history
https://github.com/status-im/nimbus-eth2/blob/unstable/docs/e2store.md
### We've fixed:
* Nimbus no longer crashes when a HTTP URL is specified as a `--web3-url` end-point:
https://github.com/status-im/nimbus-eth2/pull/3582
* The REST end-point `/eth/v1/beacon/headers` is now able to return backfilled blocks:
https://github.com/status-im/nimbus-eth2/pull/3472
* The Nimbus status bar has been disabled on Windows in order to avoid sporadic hangs in certain terminal emulators:
https://github.com/status-im/nimbus-eth2/pull/3484
* A large start-up delay after backfilling:
https://github.com/status-im/nimbus-eth2/pull/3516
* A rare problem which prevented the node from starting successfully after a trusted node sync:
https://github.com/status-im/nimbus-eth2/pull/3517
* Confusing error messages when Nimbus lacks the necessary file system permissions to create its database:
https://github.com/status-im/nimbus-eth2/pull/3536
### Removed functionality:
* The support for the Pyrmont testnet has been removed in order to reduce the Nimbus binary size:
https://github.com/status-im/nimbus-eth2/pull/3568
