## Proposed Changes
To prevent breakages from `cargo update`, this updates the `arbitrary` crate to a new commit from my fork. Unfortunately we still need to use my fork (even though my `bound` change was merged) because of this issue: https://github.com/rust-lang/rust-clippy/issues/10185.
In a couple of Rust versions it should be resolved upstream.

Currently Lighthouse will remain uncontactable if users port forward a port that is not the same as the one they are listening on.
For example, if Lighthouse runs with port 9000 TCP/UDP locally but a router is configured to pass 9010 externally to the lighthouse node on 9000, other nodes on the network will not be able to reach the lighthouse node.
This occurs because Lighthouse does not update its ENR TCP port on external socket discovery. The intention was always that users should use `--enr-tcp-port` to customise this, but this is non-intuitive.
The difficulty arises because we have no discovery mechanism to find our external TCP port. If we discovery a new external UDP port, we must guess what our external TCP port might be. This PR assumes the external TCP port is the same as the external UDP port (which may not be the case) and thus updates the TCP port along with the UDP port if the `--enr-tcp-port` flag is not set.
Along with this PR, will be added documentation to the Lighthouse book so users can correctly understand and configure their ENR to maximize Lighthouse's connectivity.
This relies on https://github.com/sigp/discv5/pull/166 and we should wait for a new release in discv5 before adding this PR.
There is a race condition which occurs when multiple discovery queries return at almost the exact same time and they independently contain a useful peer we would like to connect to.
The condition can occur that we can add the same peer to the dial queue, before we get a chance to process the queue.
This ends up displaying an error to the user:
```
ERRO Dialing an already dialing peer
```
Although this error is harmless it's not ideal.
There are two solutions to resolving this:
1. As we decide to dial the peer, we change the state in the peer-db to dialing (before we add it to the queue) which would prevent other requests from adding to the queue.
2. We prevent duplicates in the dial queue
This PR has opted for 2. because 1. will complicate the code in that we are changing states in non-intuitive places. Although this technically adds a very slight performance cost, its probably a cleaner solution as we can keep the state-changing logic in one place.
## Proposed Changes
Fix the cargo audit failure caused by [RUSTSEC-2023-0018](https://rustsec.org/advisories/RUSTSEC-2023-0018) which we were exposed to via `tempfile`.
## Additional Info
I've held back the libp2p crate for now because it seemed to introduce another duplicate dependency on libp2p-core, for a total of 3 copies. Maybe that's fine, but we can sort it out later.
## Issue Addressed
Cleans up all the remnants of 4844 in capella. This makes sure when 4844 is reviewed there is nothing we are missing because it got included here
## Proposed Changes
drop a bomb on every 4844 thing
## Additional Info
Merge process I did (locally) is as follows:
- squash merge to produce one commit
- in new branch off unstable with the squashed commit create a `git revert HEAD` commit
- merge that new branch onto 4844 with `--strategy ours`
- compare local 4844 to remote 4844 and make sure the diff is empty
- enjoy

## Issue Addressed
NA
## Proposed Changes
- Bump versions
## Sepolia Capella Upgrade
This release will enable the Capella fork on Sepolia. We are planning to publish this release on the 23rd of Feb 2023.
Users who can build from source and wish to do pre-release testing can use this branch.
## Additional Info
- [ ] Requires further testing
## Issue Addressed
#3804
## Proposed Changes
- Add `total_balance` to the validator monitor and adjust the number of historical epochs which are cached.
- Allow certain values in the cache to be served out via the HTTP API without requiring a state read.
## Usage
```
curl -X POST "http://localhost:5052/lighthouse/ui/validator_info" -d '{"indices": [0]}' -H "Content-Type: application/json" | jq
```
```
{
"data": {
"validators": {
"0": {
"info": [
{
"epoch": 172981,
"total_balance": 36566388519
},
...
{
"epoch": 172990,
"total_balance": 36566496513
}
]
},
"1": {
"info": [
{
"epoch": 172981,
"total_balance": 36355797968
},
...
{
"epoch": 172990,
"total_balance": 36355905962
}
]
}
}
}
}
```
## Additional Info
This requires no historical states to operate which mean it will still function on the freshly checkpoint synced node, however because of this, the values will populate each epoch (up to a maximum of 10 entries).
Another benefit of this method, is that we can easily cache any other values which would normally require a state read and serve them via the same endpoint. However, we would need be cautious about not overly increasing block processing time by caching values from complex computations.
This also caches some of the validator metrics directly, rather than pulling them from the Prometheus metrics when the API is called. This means when the validator count exceeds the individual monitor threshold, the cached values will still be available.

## Proposed Changes
* Bump Go from 1.17 to 1.20. The latest Geth release v1.11.0 requires 1.18 minimum.
* Prevent a cache miss during payload building by using the right fee recipient. This prevents Geth v1.11.0 from building a block with 0 transactions. The payload building mechanism is overhauled in the new Geth to improve the payload every 2s, and the tests were failing because we were falling back on a `getPayload` call with no lookahead due to `get_payload_id` cache miss caused by the mismatched fee recipient. Alternatively we could hack the tests to send `proposer_preparation_data`, but I think the static fee recipient is simpler for now.
* Add support for optionally enabling Lighthouse logs in the integration tests. Enable using `cargo run --release --features logging/test_logger`. This was very useful for debugging.
On heavily crowded networks, we are seeing many attempted connections to our node every second.
Often these connections come from peers that have just been disconnected. This can be for a number of reasons including:
- We have deemed them to be not as useful as other peers
- They have performed poorly
- They have dropped the connection with us
- The connection was spontaneously lost
- They were randomly removed because we have too many peers
In all of these cases, if we have reached or exceeded our target peer limit, there is no desire to accept new connections immediately after the disconnect from these peers. In fact, it often costs us resources to handle the established connections and defeats some of the logic of dropping them in the first place.
This PR adds a timeout, that prevents recently disconnected peers from reconnecting to us.
Technically we implement a ban at the swarm layer to prevent immediate re connections for at least 10 minutes. I decided to keep this light, and use a time-based LRUCache which only gets updated during the peer manager heartbeat to prevent added stress of polling a delay map for what could be a large number of peers.
This cache is bounded in time. An extra space bound could be added should people consider this a risk.

## Proposed Changes
Our `ERRO` stream has been rather noisy since the merge due to some unexpected behaviours of builders and EEs. Now that we've been running post-merge for a while, I think we can drop some of these `ERRO` to `WARN` so we're not "crying wolf".
The modified logs are:
#### `ERRO Execution engine call failed`
I'm seeing this quite frequently on Geth nodes. They seem to timeout when they're busy and it rarely indicates a serious issue. We also have logging across block import, fork choice updating and payload production that raise `ERRO` or `CRIT` when the EE times out, so I think we're not at risk of silencing actual issues.
#### `ERRO "Builder failed to reveal payload"`
In #3775 we reduced this log from `CRIT` to `ERRO` since it's common for builders to fail to reveal the block to the producer directly whilst still broadcasting it to the networ. I think it's worth dropping this to `WARN` since it's rarely interesting.
I elected to stay with `WARN` since I really do wish builders would fulfill their API promises by returning the block to us. Perhaps I'm just being pedantic here, I could be convinced otherwise.
#### `ERRO "Relay error when registering validator(s)"`
It seems like builders and/or mev-boost struggle to handle heavy loads of validator registrations. I haven't observed issues with validators not actually being registered, but I see timeouts on these endpoints many times a day. It doesn't seem like this `ERRO` is worth it.
#### `ERRO Error fetching block for peer ExecutionLayerErrorPayloadReconstruction`
This means we failed to respond to a peer on the P2P network with a block they requested because of an error in the `execution_layer`. It's very common to see timeouts or incomplete responses on this endpoint whilst the EE is busy and I don't think it's important enough for an `ERRO`. As long as the peer count stays high, I don't think the user needs to be actively concerned about how we're responding to peers.
## Additional Info

## Issue Addressed
Resolves the cargo-audit failure caused by https://rustsec.org/advisories/RUSTSEC-2023-0010.
I also removed the ignore for `RUSTSEC-2020-0159` as we are no longer using a vulnerable version of `chrono`. We still need the other ignore for `time 0.1` because we depend on it via `sloggers -> chrono -> time 0.1`.

## 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.~~
