Upcoming Breaking Changes

Support for the Pyrmont testnet will be removed in an upcoming release. The Prater testnet should be used instead.
Docker images will default to the JDK 17 variant in a future release.
The /teku/v1/beacon/states/:state_id endpoint has been deprecated in favor of the standard API /eth/v1/debug/beacon/states/:state_id which now returns the state as SSZ when the Accept: application/octet-stream header is specified on the request.
The /eth/v1/debug/beacon/states/:state_id endpoint has been deprecated in favor of the v2 Altair endpoint /eth/v2/debug/beacon/states/:state_id
The /eth/v1/beacon/blocks/:block_id endpoint has been deprecated in favor of the v2 Altair endpoint /eth/v2/beacon/blocks/:block_id
The /eth/v1/validator/blocks/:slot endpoint has been deprecated in favor of the v2 Altair endpoint /eth/v2/validator/blocks/:slot
The commandline option --validators-performance-tracking-enabled has been deprecated in favour of --validators-performance-tracking-mode
The commandline option --network of the validator-client subcommand introduces a new option value auto, which automatically
fetches network configuration information from the configured beacon node endpoint. Other --network option values for an external validator client
are now deprecated in favour of this option value (usage: teku validator-client --network=auto)

Added support for Apple Silicon (M1 chips).
Added LevelDB support for Linux/arm64.
Attestations are now sent to the beacon node in batches by default when using the validator-client.
Added relevant epoch to attestation and sync committee performance log message.
Support v.2.1.0 of the standard rest api. It should be noted that the 'version' has been changed to lower case to comply with the api specification.
Removed ignore rule for aggregate attestation gossip where the attestation root has previously been seen.
Added metrics to report client type of connected peers - libp2p_connected_peers_current, with client tag Teku, Lighthouse, Prysm, Nimbus, Unknown.
Updated to Javalin 4 for the rest api.
Switched executor queue size metrics to use labelled gauge.
New console message when Teku switches forks.
Reduce CPU usage by using batching signature verification service for aggregate attestation and sync committee contributions.

Fixed issue where discovery did not correctly abort handshake attempts when a request timed out.
Fixed issue where Syncing Completed message was printing multiple times.
Limited the number of validator public keys to lookup per request in voluntary-exit subcommand to avoid exceeding maximum URL length limits.
