## Issue Addressed
Using `heaptrack` I could see that ~75% of Lighthouse temporary allocations are caused by temporary string allocations here.
## Proposed Changes
Reduces temporary `String` allocations when updating metrics in the `network` crate. The solution isn't perfect since we rebuild our caches with each call, but it's a significant improvement.

## Proposed Changes
Correctly handles peer state transitions on gossipsub changes + refactors handling of peer state transitions into one function used for lighthouse score changes and gossipsub score changes.

## Issue Addressed
NA
## Proposed Changes
Increases the target peers for a subnet, so that subnet queries are executed until we have at least the minimum required peers for a mesh (`MESH_N_LOW`). We keep the limit of `6` target peers for aggregated subnet discovery queries, therefore the size (and the time needed) for a query doesn't change.
## Issue Addressed
#1606
## Proposed Changes
Uses dynamic gossipsub scoring parameters depending on the number of active validators as specified in https://gist.github.com/blacktemplar/5c1862cb3f0e32a1a7fb0b25e79e6e2c.
## Additional Info
Although the parameters got tested on Medalla, extensive testing using simulations on larger networks is still to be done and we expect that we need to change the parameters, although this might only affect constants within the dynamic parameter framework.
## Issue Addressed
Resolves#1704
## Proposed Changes
Update tiny-bip39 from using the sigp fork to the newly released v0.8.0 in the upstream.

Adds support for the [Toledo](https://github.com/protolambda/toledo) dev-net.
```bash
lighthouse --testnet toledo bn --http
```
This is for development only, we do not recommend users to join this testnet.

## Proposed Changes
- add `validator_index` to the proposer duties endpoint
- add the ability to query for historical proposer duties
- `StateId` deserialization now fails with a 400 warp rejection
- add the `validator_balances` endpoint
- update the `aggregate_and_proofs` endpoint to accept an array
- updates the attester duties endpoint from a `GET` to a `POST`
- reduces the number of times we query for proposer duties from once per slot per validator to only once per slot

## Issue Addressed
Closes#1866
## Proposed Changes
* Compact the database on finalization. This removes the deleted states from disk completely. Because it happens in the background migrator, it doesn't block other database operations while it runs. On my Medalla node it took about 1 minute and shrank the database from 90GB to 9GB.
* Fix an inefficiency in the pruning algorithm where it would always use the genesis checkpoint as the `old_finalized_checkpoint` when running for the first time after start-up. This would result in loading lots of states one-at-a-time back to genesis, and storing a lot of block roots in memory. The new code stores the old finalized checkpoint on disk and only uses genesis if no checkpoint is already stored. This makes it both backwards compatible _and_ forwards compatible -- no schema change required!
* Introduce two new `INFO` logs to indicate when pruning has started and completed. Users seem to want to know this information without enabling debug logs!
## Issue Addressed
NA
## Proposed Changes
Improves the deletion of the validator key cache lock file in case of program interrupts.
## Additional Info
This should reduce cases where a lock file doesn't get removed on shutdown and reduce complaints on Discord. This will be superseded by issue #1823.
## Proposed Changes
Update the slashing protection interchange format to v5 in preparation for finalisation as part of an EIP.
Also, add some more tests and update the commit hash for https://github.com/eth2-clients/slashing-protection-interchange-tests to include the new generated tests.
The remote signer relies on the `types` and `crypto/bls` crates from Lighthouse. Moreover, a number of tests of the remote signer consumption of LH leverages this very signer, making any important update a potential dependency nightmare.

Updates libp2p to the latest version.
This adds tokio 0.3 support and brings back yamux support.
This also updates some discv5 configuration parameters for leaner discovery queries
## Issue Addressed
NA
## Proposed Changes
Lets the networking behavior ignore messages of peers that are not connected. Furthermore, old peers are not removed from the peerdb based on score anymore but based on the disconnection time.
## Issue Addressed
Closes#1842
## Proposed Changes
Due to the lies told to us by VPS providers about what CPU features they support, we are forced to check for the availability of CPU features like ADX by just _running code and seeing if it crashes_. The prominent warning should hopefully help users who have truly incompatible CPUs work out what is going on, while not burdening users of cheap VPSs.
## Issue Addressed
We seem to have roll backed to old discv5 bootnodes with #1799 because of which fresh nodes with no cached peers cannot find any peers.
## Proposed Changes
Updates `boot_enr.yaml` to discv5.1 bootnodes.
## Issue Addressed
- Related to #1691
## Proposed Changes
Adds the following API endpoints:
- `GET lighthouse/eth1/syncing`: status about how synced we are with Eth1.
- `GET lighthouse/eth1/block_cache`: all locally cached eth1 blocks.
- `GET lighthouse/eth1/deposit_cache`: all locally cached eth1 deposits.
Additionally:
- Moves some types from the `beacon_node/eth1` to the `common/eth2` crate, so they can be used in the API without duplication.
- Allow `update_deposit_cache` and `update_block_cache` to take an optional head block number to avoid duplicate requests.
## Additional Info
TBC
## Issue Addressed
Fixes head syncing
## Proposed Changes
- Get back to statusing peers after removing chain segments and making the peer manager deal with status according to the Sync status, preventing an old known deadlock
- Also a bug where a chain would get removed if the optimistic batch succeeds being empty
## Additional Info
Tested on Medalla and looking good

## Proposed Changes
- Add quoted serde utils for `FixedVector` and `VariableList`
- Had to remove the dependency that `ssz_types` has on `serde_utils` to avoid a circular dependency.

## Issue Addressed
Resolve#1652
## Proposed Changes
Adds a cli option for voluntary exits. The flow is similar to prysm's where after entering the password for the validator keystore (or load password from `secrets` if present) the user is given multiple warnings about the operation being irreversible, then redirected to the docs webpage(not added yet) which explains what a voluntary exit is and the consequences of exiting and then prompted to enter a phrase from the docs webpage as a final confirmation.
Example usage
```
$ lighthouse --testnet zinken account validator exit --validator <validator-pubkey> --beacon-node http://localhost:5052
Running account manager for zinken testnet
validator-dir path: "..."
Enter the keystore password: for validator in ...
Password is correct
Publishing a voluntary exit for validator: ...
WARNING: This is an irreversible operation
WARNING: Withdrawing staked eth will not be possible until Eth1/Eth2 merge Please visit [website] to make sure you understand the implications of a voluntary exit.
Enter the phrase from the above URL to confirm the voluntary exit:
Exit my validator
Published voluntary exit for validator ...
```
## Additional info
Not sure if we should have batch exits (`--validator all`) option for exiting all the validators in the `validators` directory. I'm slightly leaning towards having only single exits but don't have a strong preference.
## Issue Addressed

## Proposed Changes
As raised by @hermanjunge in a DM, the `http_api` tests have been observed taking 100+ minutes on debug. This PR:
- Moves the `http_api` tests to only run in release.
- Groups some `http_api` tests to reduce test-setup overhead.

## Issue Addressed
Michael's comment here: https://github.com/sigp/lighthouse/issues/1434#issuecomment-708834079Resolves#1808
## Proposed Changes
- Add query param `id` and `status` to the `validators` endpoint
- Add string serialization and deserialization for `ValidatorStatus`
- Drop `Epoch` from `ValidatorStatus` variants
## Additional Info
Please provide any additional information. For example, future considerations
or information useful for reviewers.
## Issue Addressed
Sync edge case when we get an empty optimistic batch that passes validation and is inside the download buffer. Eventually the chain would reach the batch and treat it as an ugly state.
## Proposed Changes
- Handle the edge case advancing the chain's target + code clarification
- Some largey changes for readability + ergonomics since rust has try ops
- Better handling of bad batch and chain states
## Issue Addressed
NA
## Proposed Changes
Currently a banned peer will remain banned indefinitely as long as update is called on the score struct regularly. This fixes this bug and the score decay starts after `BANNED_BEFORE_DECAY` seconds after banning.
## Issue Addressed
Closes#1504Closes#1505
Replaces #1703Closes#1707
## Proposed Changes
* Update BLST and Milagro to versions compatible with BLSv4 spec
* Update Lighthouse to spec v1.0.0-rc.0, and update EF test vectors
* Use the v1.0.0 constants for `MainnetEthSpec`.
* Rename `InteropEthSpec` -> `V012LegacyEthSpec`
* Change all constants to suit the mainnet `v0.12.3` specification (i.e., Medalla).
* Deprecate the `--spec` flag for the `lighthouse` binary
* This value is now obtained from the `config_name` field of the `YamlConfig`.
* Built in testnet YAML files have been updated.
* Ignore the `--spec` value, if supplied, log a warning that it will be deprecated
* `lcli` still has the spec flag, that's fine because it's dev tooling.
* Remove the `E: EthSpec` from `YamlConfig`
* This means we need to deser the genesis `BeaconState` on-demand, but this is fine.
* Swap the old "minimal", "mainnet" strings over to the new `EthSpecId` enum.
* Always require a `CONFIG_NAME` field in `YamlConfig` (it used to have a default).
## Additional Info
Lots of breaking changes, do not merge! ~~We will likely need a Lighthouse v0.4.0 branch, and possibly a long-term v0.3.0 branch to keep Medalla alive~~.

## Issue Addressed
#1825
## Proposed Changes
Since we penalize more blocks by range requests that have large steps, it is possible to get requests that will never be processed. We were not informing peers about this requests and also logging CRIT that is no longer relevant. Later we should check if more sophisticated handling for those requests is needed
## Issue Addressed
NA
## Proposed Changes
Fixes a bug which causes the node to reject valid eth1 nodes.
- Fix core bug: failure to apply `YamlConfig` values to `ChainSpec`.
- Add a test to prevent regression in this specific case.
- Fix an invalid log message
## Additional Info
NA
## Issue Addressed
NA
## Proposed Changes
- Panic or return error if we overflow `usize` in SSZ decoding/encoding derive macros.
- I claim that the panics can only be triggered by a faulty type definition in lighthouse, they cannot be triggered externally on a validly defined struct.
- Use `Ordering` instead of some `if` statements, as demanded by clippy.
- Remove some old clippy `allow` that seem to no longer be required.
- Add comments to interesting clippy statements that we're going to continue to ignore.
- Create #1713
## Additional Info
NA
## Issue Addressed
- Related to #1691
## Proposed Changes
- Add `DEPOSIT_CHAIN_ID` and `DEPOSIT_NETWORK_ID` to `config.yaml`.
- Pass the `DEPOSIT_NETWORK_ID` to the `eth1::Service`.
- Remove the unused `MAX_EPOCHS_PER_CROSSLINK` from the `altona` and `medalla` configs (see [spec commit](2befe90032 (diff-efb845ac2ebd4aafbc23df40f47ce25699255064e99d36d0406d0a14ca7953ec))).
- Change from compressing the whole testnet directory, to only compressing the genesis state file. This is the only file we need to compress and *not* compressing the others makes them work nicely with git.
- We can modify the boot nodes, configs, etc. without incurring an eternal binary-blob cost on our git history.
- This change is backwards compatible (i.e., non-breaking).
## Additional Info
NA
## Issue Addressed
Further testing revealed another edge case where we attempt to unban a peer that can be in a disconnected start. Although this causes no real issue, it does log an error to the user.
This PR adds a check to prevent this edge case and prevents the error being logged to the user.
This PR prevents a user-facing error.
It prevents optimistically unbanning a peer and instead checks the state of the peer before requesting the peers state to be unbanned.
As @AgeManning mentioned the newest libp2p version had some problems and got downgraded again on lighthouse master. This is an intermediate version that makes no problems and only adds a small change of allowing only one topic per message.
## Description
This downgrades the recent libp2p upgrade.
There were issues with the RPC which prevented syncing of the chain and this upgrade needs to be further investigated.
## Issue Addressed
NA
## Proposed Changes
- Update progress timeline
- Remove the qualification that the eth2 spec is "emerging".
- Remove the terminal animation, replace with new banner.
## Additional Info

## Overview
This updates lighthouse to discovery v5.1
Note: This makes lighthouse's discovery not compatible with any previous version. Lighthouse cannot discover peers or send/receive ENR's from any previous version. This is a breaking change.
This resolves#1605
## Description
This increases the logging of the underlying UPnP tasks to inform the user of UPnP error/success.
This also decreases the batch syncing size to two epochs per batch.
