+- Do not switch Erigon repo to `erigontech/erigon`, yet, until images there contain `linux/amd64`
+
+Bug Fixes

+
+*This is an optional release*
+
+Changes
+- Reth full sync now supports RocketPool, SSV and StakeWise by including their contracts for eth_getLogs / receipts.

+- Updated SSV dashboards
+- Add `./ethd keys count` command. Thanks @Hydepwns!

+- Use Go 1.23 for source builds
+- Support IPv6 for traefik
+- Besu sync mode and RPC API can be configured with `EL_EXTRAS`
+- Do not override Nethermind's `--Pruning.CacheMb`, as it was causing performance issues
+- Offer Prysm on ARM64
+- Offer Erigon on ARM64
+- Clarify the OS version nag
+- Source build for Teku and Besu uses Noble Numbat
+- Fresh sync of Besu, Geth or Nethermind prefers a Docker volume without `eth1` in the name
+
+Bug fixes
+- Only use `sudo` for `dkg_output` directory permission changes when needed. Thanks @jshufro!
