## Issue Addressed
Partially addresses #3707
## Proposed Changes
Drop `ERRO` log to `WARN` until we identify the exact conditions that lead to this case.
Add a message which hopefully reassures users who only see this log once 😅
Add the block hash to the error message in case it will prove useful in debugging the root cause.

## Proposed Changes
With a few different changes to the gossip topics in flight (light clients, Capella, 4844, etc) I think this simplification makes sense. I noticed it while plumbing through a new Capella topic.
## Issue Addressed
Closes#3709
## Proposed Changes
Add the job `compile-with-beta-compiler` to `test-suite`. This job has the following steps:
1. Use `actions/checkout@v3`. (Needed to run make in a later step.)
2. Install the dependencies listed in [build from source guide](https://lighthouse-book.sigmaprime.io/installation-source.html).
3. Change the compiler to the current beta version with `rustup override`.
4. Run `make`.
This PR adds some health endpoints for the beacon node and the validator client.
Specifically it adds the endpoint:
`/lighthouse/ui/health`
These are not entirely stable yet. But provide a base for modification for our UI.
These also may have issues with various platforms and may need modification.
## Issue Addressed
Closes https://github.com/sigp/lighthouse/issues/3656
## Proposed Changes
* Replace `set-output` by `$GITHUB_OUTPUT` usage
* Avoid rate-limits when installing `protoc` by making authenticated requests (continuation of https://github.com/sigp/lighthouse/pull/3621)
* Upgrade all Ubuntu 18.04 usage to 22.04 (18.04 is end of life)
* Upgrade macOS-latest to explicit macOS-12 to silence warning
* Use `actions/checkout@v3` and `actions/cache@v3` to avoid deprecated NodeJS v12
## Additional Info
Can't silence the NodeJS warnings entirely due to https://github.com/sigp/lighthouse/issues/3705. Can fix that in future.
## Issue Addressed
Closes#3612
## Proposed Changes
- Iterates through BNs until it finds a non-optimistic head.
A slight change in error behavior:
- Previously: `spawn_contribution_tasks` did not return an error for a non-optimistic block head. It returned `Ok(())` logged a warning.
- Now: `spawn_contribution_tasks` returns an error if it cannot find a non-optimistic block head. The caller of `spawn_contribution_tasks` then logs the error as a critical error.

## Issue Addressed
Part of https://github.com/sigp/lighthouse/issues/3651.
## Proposed Changes
Add a flag for enabling the light client server, which should be checked before gossip/RPC traffic is processed (e.g. https://github.com/sigp/lighthouse/pull/3693, https://github.com/sigp/lighthouse/pull/3711). The flag is available at runtime from `beacon_chain.config.enable_light_client_server`.
Additionally, a new method `BeaconChain::with_mutable_state_for_block` is added which I envisage being used for computing light client updates. Unfortunately its performance will be quite poor on average because it will only run quickly with access to the tree hash cache. Each slot the tree hash cache is only available for a brief window of time between the head block being processed and the state advance at 9s in the slot. When the state advance happens the cache is moved and mutated to get ready for the next slot, which makes it no longer useful for merkle proofs related to the head block. Rather than spend more time trying to optimise this I think we should continue prototyping with this code, and I'll make sure `tree-states` is ready to ship before we enable the light client server in prod (cf. https://github.com/sigp/lighthouse/pull/3206).
## Additional Info
I also fixed a bug in the implementation of `BeaconState::compute_merkle_proof` whereby the tree hash cache was moved with `.take()` but never put back with `.restore()`.

## Proposed Changes
`blocks` and `block_min_delay` are never updated in the epoch summary
Co-authored-by: Michael Sproul <micsproul@gmail.com>
## Issue Addressed
This PR addresses partially #3651
## Proposed Changes
This PR adds the following methods:
* a new method to trait `TreeHash`, `hash_tree_leaves` which returns all the Merkle leaves of the ssz object.
* a new method to `BeaconState`: `compute_merkle_proof` which generates a specific merkle proof for given depth and index by using the `hash_tree_leaves` as leaves function.
## Additional Info
Now here is some rationale on why I decided to go down this route: adding a new function to commonly used trait is a pain but was necessary to make sure we have all merkle leaves for every object, that is why I just added `hash_tree_leaves` in the trait and not `compute_merkle_proof` as well. although it would make sense it gives us code duplication/harder review time and we just need it from one specific object in one specific usecase so not worth the effort YET. In my humble opinion.

## Proposed Changes
* Add v3.2 and v3.3 to database migrations table
* Remove docs on `--subscribe-all-subnets` and `--import-all-attestations` from redundancy docs
* Clarify that the merge has already occurred on the merge migration page
## Issue Addressed
NA
## Proposed Changes
Adds clarification to an error log when there is an error submitting a validator registration.
There seems to be a few cases where relays return errors during validator registration, including spurious timeouts and when a validator has been very recently activated/made pending.
Changing this log helps indicate that it's "just another registration error" rather than something more serious. I didn't drop this to a `WARN` since I still have hope we can eliminate these errors completely by chatting with relays and adjusting timeouts.

## Summary
The deposit cache now has the ability to finalize deposits. This will cause it to drop unneeded deposit logs and hashes in the deposit Merkle tree that are no longer required to construct deposit proofs. The cache is finalized whenever the latest finalized checkpoint has a new `Eth1Data` with all deposits imported.
This has three benefits:
1. Improves the speed of constructing Merkle proofs for deposits as we can just replay deposits since the last finalized checkpoint instead of all historical deposits when re-constructing the Merkle tree.
2. Significantly faster weak subjectivity sync as the deposit cache can be transferred to the newly syncing node in compressed form. The Merkle tree that stores `N` finalized deposits requires a maximum of `log2(N)` hashes. The newly syncing node then only needs to download deposits since the last finalized checkpoint to have a full tree.
3. Future proofing in preparation for [EIP-4444](https://eips.ethereum.org/EIPS/eip-4444) as execution nodes will no longer be required to store logs permanently so we won't always have all historical logs available to us.
## More Details
Image to illustrate how the deposit contract merkle tree evolves and finalizes along with the resulting `DepositTreeSnapshot`
## Other Considerations
I've changed the structure of the `SszDepositCache` so once you load & save your database from this version of lighthouse, you will no longer be able to load it from older versions.

## Issue Addressed
This PR partially addresses #3651
## Proposed Changes
This PR adds the following containers types from [the lightclient specs](https://github.com/ethereum/consensus-specs/blob/dev/specs/altair/light-client/sync-protocol.md): `LightClientUpdate`, `LightClientFinalityUpdate`, `LightClientOptimisticUpdate` and `LightClientBootstrap`. It also implements the creation of each updates as delined by this [document](https://github.com/ethereum/consensus-specs/blob/dev/specs/altair/light-client/full-node.md).
## Additional Info
Here is a brief description of what each of these container signify:
`LightClientUpdate`: This container is only provided by server (full node) to lightclients when catching up new sync committees beetwen periods and we want possibly one lightclient update ready for each post-altair period the lighthouse node go over. it is needed in the resp/req in method `light_client_update_by_range`.
`LightClientFinalityUpdate/LightClientFinalityUpdate`: Lighthouse will need only the latest of each of this kind of updates, so no need to store them in the database, we can just store the latest one of each one in memory and then just supply them via gossip or respreq, only the latest ones are served by a full node. finality updates marks the transition to a new finalized header, while optimistic updates signify new non-finalized header which are imported optimistically.
`LightClientBootstrap`: This object is retrieved by lightclients during the bootstrap process after a finalized checkpoint is retrieved, ideally we want to store a LightClientBootstrap for each finalized root and then serve each of them by finalized root in respreq protocol id `light_client_bootstrap`.
Little digression to how we implement the creation of each updates: the creation of a optimistic/finality update is just a version of the lightclient_update creation mechanism with less fields being set, there is underlying concept of inheritance, if you look at the specs it becomes very obvious that a lightclient update is just an extension of a finality update and a finality update an extension to an optimistic update.
## Extra note
`LightClientStore` is not implemented as it is only useful as internal storage design for the lightclient side.

## Issue Addressed
This reverts commit ca9dc8e094 (PR #3559) with some modifications.
## Proposed Changes
Unfortunately that PR introduced a performance regression in fork choice. The optimisation _intended_ to build the exit and pubkey caches on the head state _only if_ they were not already built. However, due to the head state always being cloned without these caches, we ended up building them every time the head changed, leading to a ~70ms+ penalty on mainnet.
fcfd02aeec/beacon_node/beacon_chain/src/canonical_head.rs (L633-L636)
I believe this is a severe enough regression to justify immediately releasing v3.2.1 with this change.
## Additional Info
I didn't fully revert #3559, because there were some unrelated deletions of dead code in that PR which I figured we may as well keep.
An alternative would be to clone the extra caches, but this likely still imposes some cost, so in the interest of applying a conservative fix quickly, I think reversion is the best approach. The optimisation from #3559 was not even optimising a particularly significant path, it was mostly for VCs running larger numbers of inactive keys. We can re-do it in the `tree-states` world where cache clones are cheap.
## Issue Addressed
NA
## Proposed Changes
Bump version to `v3.2.0`
## Additional Info
- ~~Blocked on #3597~~
- ~~Blocked on #3645~~
- ~~Blocked on #3653~~
- ~~Requires additional testing~~
## Issue Addressed
I missed this from https://github.com/sigp/lighthouse/pull/3491. peers were being banned at the behaviour level only. The identify errors are explained by this as well
## Proposed Changes
Add banning and unbanning
## Additional Info
Befor,e having tests that catch this was hard because the swarm was outside the behaviour. We could now have tests that prevent something like this in the future
## Issue Addressed
I noticed that [this build](https://github.com/sigp/lighthouse/actions/runs/3269950873/jobs/5378036501) wasn't marked failed by Bors when the `syncing-simulator-ubuntu` job failed. This is because that job is absent from the `bors.toml` config.
## Proposed Changes
Add missing jobs to Bors config so that they are required:
- `syncing-simulator-ubuntu`
- `slasher-tests`
- `disallowed-from-async-lint`
The `disallowed-from-async-lint` was previously allowed to fail because it was considered beta, but I think it's stable enough now we may as well require it.
Overrides any previous option that enables the eth1 service.
Useful for operating a `light` beacon node.
