## Proposed Changes
Remove the `[patch]` for `fixed-hash`.
We pinned it years ago in #2710 to fix `arbitrary` support. Nowadays the 0.7 version of `fixed-hash` is only used by the `web3` crate and doesn't need `arbitrary`.
~~Blocked on #3916 but could be merged in the same Bors batch.~~

## Proposed Changes
Clippy 1.67.0 put us on blast for the size of some of our errors, most of them written by me ( 👀 ). This PR shrinks the size of `BeaconChainError` by dropping some extraneous info and boxing an inner error which should only occur infrequently anyway.
For the `AttestationSlashInfo` and `BlockSlashInfo` I opted to ignore the lint as they are always used in a `Result<A, Info>` where `A` is a similar size. This means they don't bloat the size of the `Result`, so it's a bit annoying for Clippy to report this as an issue.
I also chose to ignore `clippy::uninlined-format-args` because I think the benefit-to-churn ratio is too low. E.g. sometimes we have long identifiers in `format!` args and IMO the non-inlined form is easier to read:
```rust
// I prefer this...
format!(
"{} did {} to {}",
REALLY_LONG_CONSTANT_NAME,
ANOTHER_REALLY_LONG_CONSTANT_NAME,
regular_long_identifier_name
);
// To this
format!("{REALLY_LONG_CONSTANT_NAME} did {ANOTHER_REALLY_LONG_CONSTANT_NAME} to {regular_long_identifier_name}");
```
I tried generating an automatic diff with `cargo clippy --fix` but it came out at:
```
250 files changed, 1209 insertions(+), 1469 deletions(-)
```
Which seems like a bad idea when we'd have to back-merge it to `capella` and `eip4844` 😱
## Issue Addressed
Currently there is a race between receiving blocks and receiving light client optimistic updates (in unstable), which results in processing errors. This is a continuation of PR #3693 and seeks to progress on issue #3651
## Proposed Changes
Add the parent_root to ReprocessQueueMessage::BlockImported so we can remove blocks from queue when a block arrives that has the same parent root. We use the parent root as opposed to the block_root because the LightClientOptimisticUpdate does not contain the block_root.
If light_client_optimistic_update.attested_header.canonical_root() != head_block.message().parent_root() then we queue the update. Otherwise we process immediately.
## Additional Info
michaelsproul came up with this idea.
The code was heavily based off of the attestation reprocessing.
I have not properly tested this to see if it works as intended.

We recently ran a large-block experiment on the testnet and plan to do a further experiment on mainnet.
Although the metrics recovered from lighthouse nodes were quite useful, I think we could do with greater resolution in the block delay metrics and get some specific values for each block (currently these can be lost to large exponential histogram buckets).
This PR increases the resolution of the block delay histogram buckets, but also introduces a new metric which records the last block delay. Depending on the polling resolution of the metric server, we can lose some block delay information, however it will always give us a specific value and we will not lose exact data based on poor resolution histogram buckets.

No issue has been raised for these broken links.
## Proposed Changes
Update links with the new URLs for the same document.
## Additional Info
~The link for the [Lighthouse Development Updates](https://eepurl.com/dh9Lvb/) mailing list is also broken, but I can't find the correct link.~

## Issue Addressed
#3853
## Proposed Changes
Added `INFO` level logs for requesting and receiving the unsigned block.
## Additional Info
Logging for successfully publishing the signed block is already there. And seemingly there is a log for when "We realize we are going to produce a block" in the `start_update_service`: `info!(log, "Block production service started");
`. Is there anywhere else you'd like to see logging around this event?

## Issue Addressed
#3780
## Proposed Changes
Add error reporting that notifies the node operator that the `voting_keystore_path` in their `validator_definitions.yml` file may be incorrect.
## Additional Info
There is more info in issue #3780

## Proposed Changes
Decouple the stdout and logfile formats by adding the `--logfile-format` CLI flag.
This behaves identically to the existing `--log-format` flag, but instead will only affect the logs written to the logfile.
The `--log-format` flag will no longer have any effect on the contents of the logfile.
## Additional Info
This avoids being a breaking change by causing `logfile-format` to default to the value of `--log-format` if it is not provided.
This means that users who were previously relying on being able to use a JSON formatted logfile will be able to continue to use `--log-format JSON`.
Users who want to use JSON on stdout and default logs in the logfile, will need to pass the following flags: `--log-format JSON --logfile-format DEFAULT`
## Issue Addressed
Issue #3112
## Proposed Changes
Add `Filter::recover` to the GET chain to handle rejections specifically as 404 NOT FOUND
## Additional Info
Making a request to `http://localhost:5052/not_real` now returns the following:
```
{
"code": 404,
"message": "NOT_FOUND",
"stacktraces": []
}
```

## Proposed Changes
Update all dependencies to new semver-compatible releases with `cargo update`. Importantly this patches a Tokio vuln: https://rustsec.org/advisories/RUSTSEC-2023-0001. I don't think we were affected by the vuln because it only applies to named pipes on Windows, but it's still good hygiene to patch.

## Proposed Changes
Myself and others (#3678) have observed that when running with lots of validators (e.g., 1000s) the cardinality is too much for Prometheus. I've seen Prometheus instances just grind to a halt when we turn the validator monitor on for our testnet validators (we have 10,000s of Goerli validators). Additionally, the debug log volume can get very high with one log per validator, per attestation.
To address this, the `bn --validator-monitor-individual-tracking-threshold <INTEGER>` flag has been added to *disable* per-validator (i.e., non-aggregated) metrics/logging once the validator monitor exceeds the threshold of validators. The default value is `64`, which is a finger-to-the-wind value. I don't actually know the value at which Prometheus starts to become overwhelmed, but I've seen it work with ~64 validators and I've seen it *not* work with 1000s of validators. A default of `64` seems like it will result in a breaking change to users who are running millions of dollars worth of validators whilst resulting in a no-op for low-validator-count users. I'm open to changing this number, though.
Additionally, this PR starts collecting aggregated Prometheus metrics (e.g., total count of head hits across all validators), so that high-validator-count validators still have some interesting metrics. We already had logging for aggregated values, so nothing has been added there.
I've opted to make this a breaking change since it can be rather damaging to your Prometheus instance to accidentally enable the validator monitor with large numbers of validators. I've crashed a Prometheus instance myself and had a report from another user who's done the same thing.
## Additional Info
NA
## Breaking Changes Note
A new label has been added to the validator monitor Prometheus metrics: `total`. This label tracks the aggregated metrics of all validators in the validator monitor (as opposed to each validator being tracking individually using its pubkey as the label).
Additionally, a new flag has been added to the Beacon Node: `--validator-monitor-individual-tracking-threshold`. The default value is `64`, which means that when the validator monitor is tracking more than 64 validators then it will stop tracking per-validator metrics and only track the `all_validators` metric. It will also stop logging per-validator logs and only emit aggregated logs (the exception being that exit and slashing logs are always emitted).
These changes were introduced in #3728 to address issues with untenable Prometheus cardinality and log volume when using the validator monitor with high validator counts (e.g., 1000s of validators). Users with less than 65 validators will see no change in behavior (apart from the added `all_validators` metric). Users with more than 65 validators who wish to maintain the previous behavior can set something like `--validator-monitor-individual-tracking-threshold 999999`.
