## Issue Addressed
Synchronize dependencies and edition on the workspace `Cargo.toml`
## Proposed Changes
with https://github.com/rust-lang/cargo/issues/8415 merged it's now possible to synchronize details on the workspace `Cargo.toml` like the metadata and dependencies.
By only having dependencies that are shared between multiple crates aligned on the workspace `Cargo.toml` it's easier to not miss duplicate versions of the same dependency and therefore ease on the compile times.
## Additional Info
this PR also removes the no longer required direct dependency of the `serde_derive` crate.
should be reviewed after https://github.com/sigp/lighthouse/pull/4639 get's merged.

## Issue Addressed
#4635
## Proposed Changes
Wrap the `SignedVoluntaryExit` object in a `GenericResponse` container, adding an additional `data` layer, to ensure compliance with the key manager API specification.
The new response would look like this:
```json
{"data":{"message":{"epoch":"196868","validator_index":"505597"},"signature":"0xhexsig"}}
```
This is a backward incompatible change and will affect Siren as well.
## Issue Addressed

## Proposed Changes
Bumps `quinn-proto` to address a QUIC-related vulnerability: https://rustsec.org/advisories/RUSTSEC-2023-0063
Fixes a `cargo audit` failure.
## Additional Info
NA
## Issue Addressed
Closes#4751
## Proposed Changes
Prevent `state_root_at_slot` and `block_root_at_slot` from erroring out due to a call to `self.slot()?` that fails before genesis. This fixes pre-genesis queries for:
- block at slot 0
- block by genesis block root
- state at slot 0
- state by genesis state root
- state at `finalized` tag
- state at `justified` tag
## Issue Addressed
#4531
## Proposed Changes
add SSZ support to the following block production endpoints:
GET /eth/v2/validator/blocks/{slot}
GET /eth/v1/validator/blinded_blocks/{slot}
## Additional Info
i updated a few existing tests to use ssz instead of writing completely new tests
## Issue Addressed
#4738
## Proposed Changes
See the above issue for details. Went with option #2 to use the async reqwest client in `Eth2NetworkConfig` and propagate the async-ness.
## Issue Addressed
We're OOM'ing on Docker builds on the Deneb branch https://github.com/sigp/lighthouse/issues/3929
Are we ok to self host automated docker builds?

Fix local testnet to generate keys in the correct folders when `BN_COUNT` and `VC_COUNT` don't match.
The current script place the generated validator keys in validator folders based on the `BN_COUNT` config, e.g. `node_1/validators`, `node_2/validators`..etc. We should be using `VC_COUNT` here instead, otherwise the number of validator clients may not match the number of directories generated, and would result in either:
1. a VC not having any keys (when `BN_COUNT` < `VC_COUNT`)
2. a validator key directory not being used (when `BN_COUNT` > `VC_COUNT`).
There is an issue with the file `scripts/local_testnet/start_local_testnet.sh` - when we use a non-default `$SPEC-PRESET` in `vars.env` it runs into an error:
```
executing: ./setup.sh >> /home/ck/.lighthouse/local-testnet/testnet/setup.log
parse error: Invalid numeric literal at line 1, column 7
```
@jimmygchen found the issue and the updated script includes the flag `--spec $SPEC-PRESET`
## Proposed Changes
This PR adds more logging prior to genesis, particularly on networks that start with execution enabled.
There are new checks using `eth_getBlockByHash/Number` to verify that the genesis state's `latest_execution_payload_header` matches the execution node's genesis block.
The first commit also runs the merge-readiness/Capella-readiness checks prior to genesis. This has two effects:
- Give more information on the execution node's status and its readiness for genesis.
- Prevent the `el_offline` status from being set on `/eth/v1/node/syncing`, which previously caused the VC to complain loudly.
I would like to include this for the Holesky reboot. It would have caught the misconfig that doomed the first Holesky.
## Additional Info
- Geth doesn't serve payload bodies prior to genesis, which is why we use the legacy methods. I haven't checked with other ELs yet.
- Currently this is logging errors with _Capella_ genesis states generated by `ethereum-genesis-generator` because the `withdrawals_root` is not set correctly (it is 0x0). This is not a blocker for Holesky, as it starts from Bellatrix (Pari is investigating).
## Issue Addressed
I went through the code base and look for places where we acquire fork choice locks (after the deadlock bug was found and fixed in #4687), and discovered an instance where we re-acquire a lock immediately after dropping it. This shouldn't cause deadlock like the other issue, but is slightly less efficient.
## Issue Addressed
CI is plagued by `AddrAlreadyInUse` failures, which are caused by race conditions in allocating free ports.
This PR removes all usages of the `unused_port` crate for Lighthouse's HTTP API, in favour of passing `:0` as the listen address. As a result, the listen address isn't known ahead of time and must be read from the listening socket after it binds. This requires tying some self-referential knots, which is a little disruptive, but hopefully doesn't clash too much with Deneb 🤞
There are still a few usages of `unused_tcp4_port` left in cases where we start external processes, like the `watch` Postgres DB, Anvil, Geth, Nethermind, etc. Removing these usages is non-trivial because it's hard to read the port back from an external process after starting it with `--port 0`. We might be able to do something on Linux where we read from `/proc/`, but I'll leave that for future work.
* Implement `SignedBlockContent` decoding and fixed bug in `SignedBlockContent::new`
* Update Cargo.lock file
* Use `make_genesis_spec` to simplify test setup.
* Fix syntax errors.
## Issue Addressed
On a new network a user might require importing validators before waiting until genesis has occurred.
## Proposed Changes
Starts the validator client http api before waiting for genesis

* typo persist_data_availabilty_checker -> persist_data_availability_checker
* unify cheap_state_advance_to_obtain_committees
## Issue Addressed
#4402
## Proposed Changes
This PR adds QUIC support to Lighthouse. As this is not officially spec'd this will only work between lighthouse <-> lighthouse connections. We attempt a QUIC connection (if the node advertises it) and if it fails we fallback to TCP.
This should be a backwards compatible modification. We want to test this functionality on live networks to observe any improvements in bandwidth/latency.
NOTE: This also removes the websockets transport as I believe no one is really using it. It should be mentioned in our release however.

I noticed a node.js version warning on our CI, and thought about updating the version to get rid of this warning, but then realized we may not need node.js anymore now we're using `anvil` instead of `ganache`.

Siren FAQ requires more information regarding network connections to lighthouse BN/VC
## Proposed Changes
Added more info regarding port, BN/VC flags, ssh tunneling and VPNs access

## Proposed Changes
The current Advanced Networking page references the ["--listen-addresses"](14924dbc95/book/src/advanced_networking.md (L124C8-L124C8)) argument, which does not exist in the beacon node. This PR changes such instances of "--listen-addresses" to "--listen-address".
Additionally, the page mentions using sockets that [both listen to IPv6](14924dbc95/book/src/advanced_networking.md (L151)) in a dual-stack setup? Hence, this PR also changes said line to "using one socket for IPv4 and another socket for IPv6".
## Additional Info
None.
## Proposed Changes
New release to replace the cancelled v4.4.0 release.
This release includes the bugfix #4687 which avoids a deadlock that was present in v4.4.0.
## Additional Info
Awaiting testing over the weekend this will be merged Monday September 4th.
## Issue Addressed
Fix a deadlock introduced in #4236 which was caught during the v4.4.0 release testing cycle (with thanks to @paulhauner and `gdb`).
## Proposed Changes
Avoid re-locking the fork choice read lock when querying a state by root in the HTTP API. This avoids a deadlock due to the lock already being held.
## Additional Info
The [RwLock docs](https://docs.rs/lock_api/latest/lock_api/struct.RwLock.html#method.read) explicitly advise against re-locking:
> Note that attempts to recursively acquire a read lock on a RwLock when the current thread already holds one may result in a deadlock.
