## Issue Addressed
Closes#1889
## Proposed Changes
- Error when passwords which use invalid UTF-8 characters during encryption.
- Add some tests
## Additional Info
I've decided to error when bad characters are used to create/encrypt a keystore but think we should allow them during decryption since either the keystore was created
- with invalid UTF-8 characters (possibly by another client or someone whose password is random bytes) in which case we'd want them to be able to decrypt their keystore using the right key.
- without invalid characters then the password checksum would almost certainly fail.
Happy to add them to decryption if we want to make the decryption more trigger happy 😋 , it would only be a one line change and would tell the user which character index is causing the issue.

## Issue Addressed
Catching up on a few eth2 spec updates:
## Proposed Changes
- adding query params to the `GET pool/attestations` endpoint
- allowing the `POST pool/attestations` endpoint to accept an array of attestations
- batching attestation submission
- moving `epoch` from a path param to a query param in the `committees` endpoint

## Proposed Changes
Removes most of the temporary string initializations in network metrics and replaces them by directly using `&str`. This further improves on PR https://github.com/sigp/lighthouse/pull/1895.
For the subnet id handling the current approach uses a build script to create a static map. This has the disadvantage that the build script hardcodes the number of subnets. If we want to use more than 64 subnets we need to adjust this in the build script.
## Additional Info
We still have some string initializations for the enum `PeerKind`. To also replace that by `&str` I created a PR in the libp2p dependency: https://github.com/sigp/rust-libp2p/pull/91. Either we wait with merging until this dependency PR is merged (and all conflicts with the newest libp2p version are resolved) or we just merge as is and I will create another PR when the dependency is ready.

## Proposed Changes
Users on Discord (and @protolambda) have experienced this error (or variants of it):
```
Failed to update eth1 cache: GetDepositLogsFailed("Eth1 node returned error: {\"code\":-32005,\"message\":\"query returned more than 10000 results\"}")
```
This PR allows users to reduce the span of blocks searched for deposit logs and therefore reduce the size of the return result. Hopefully experimentation with this flag can lead to finding a better default value.

*Should* address #1917
## Proposed Changes
Stops the `BackgroupMigrator` rx channel from backing up with big `BeaconState` messages.
Looking at some logs from my Medalla node, we can see a discrepancy between the head finalized epoch and the migrator finalized epoch:
```

```
I believe this indicates that the migrator rx has a backed-up queue of `MigrationNotification` items which each contain a `BeaconState`.
## TODO
- [x] Remove finalized state requirement for op-pool
## Proposed Changes
In an attempt to fix OOM issues and database consistency issues observed by some users after the introduction of compaction in v0.3.4, this PR makes the following changes:
* Run compaction less often: roughly every 1024 epochs, including after long periods of non-finality. I think the division check proposed by Paul is pretty solid, and ensures we don't miss any events where we should be compacting. LevelDB lacks an easy way to check the size of the DB, which would be another good trigger.
* Make it possible to disable the compaction on finalization using `--auto-compact-db=false`
* Make it possible to trigger a manual, single-threaded foreground compaction on start-up using `--compact-db`
* Downgrade the pruning log to `DEBUG`, as it's particularly noisy during sync
I would like to ship these changes to affected users ASAP, and will document them further in the Advanced Database section of the book if they prove effective.

## Issue Addressed
A peer might send a lot of requests that comply to the rate limit and the disconnect, this humongous pr makes sure we don't process them if the peer is not connected
## Issue Addressed
Password length check too short (https://github.com/sigp/lighthouse/issues/1880)

I've added function that counts number of unicode characters, instead of calling String::len()

This PR adds a number of improvements:
- Downgrade a warning log when we ignore blocks for gossipsub processing
- Revert a a correction to improve logging of peer score changes
- Shift syncing DB reads off the core-executor allowing parallel processing of large sync messages
- Correct the timeout logic of RPC chunk sends, giving more time before timing out RPC outbound messages.
## Issue Addressed
NA
## Proposed Changes
- Replace Zinken with Pyrmont (Zinken has been sun-setted).
- Ensure Mainnet is build in the build script.
## Additional Info
NA
## Issue Addressed
- RPC Errors were being logged twice: first in the peer manager and then again in the router, so leave just the peer manager's one
- The "reduce peer count" warn message gets thrown to the user for every missed chunk, so instead print it when the request times out and also do not include there info that is not relevant to the user
- The processor didn't have the service tag so add it
- Impl `KV` for status message
- Do not downscore peers if we are the ones that timed out
Other small improvements
## Issue Addressed
Resolves#1801
## Proposed Changes
Verify queries to `attestation_data` are for no later than `current_slot + 1`. If they are later than this, return a 400.

## Issue Addressed
#1856
## Proposed Changes
- For clarity, the router's processor now only decides if a peer is compatible and it disconnects it or sends it to sync accordingly. No logic here regarding how useful is the peer.
- Update peer_sync_info's rules
- Add an `IrrelevantPeer` sync status to account for incompatible peers (maybe this should be "IncompatiblePeer" now that I think about it?) this state is update upon receiving an internal goodbye in the peer manager
- Misc code cleanups
- Reduce the need to create `StatusMessage`s (and thus, `Arc` accesses )
- Add missing calls to update the global sync state
The overall effect should be:
- More peers recognized as Behind, and less as Unknown
- Peers identified as incompatible
## Issue Addressed
- Asymmetric pings - Currently with symmetric ping intervals, lighthouse nodes race each other to ping often ending in simultaneous ping connections. This shifts the ping interval to be asymmetric based on inbound/outbound connections
- Correct inbound/outbound peer-db registering - It appears we were accounting inbound as outbound and vice versa in the peerdb, this has been corrected
- Improved logging
There is likely more to come - I'll leave this open as we investigate further testnets
## 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
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
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

## 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.

## 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.
