 ### Additions and Improvements
 - Improved compatibility with `/eth/v3/validator/blocks/{slot}` experimental beacon API for block production. It can now respond with blinded and unblinded content based on the block production flow. It also supports the `builder_boost_factor` parameter.
 - Add `block_gossip` SSE event as per /~https://github.com/ethereum/beacon-APIs/pull/405
-- - Deposit tree snapshots will be downloaded from checkpoint-sync-url when available [#7715](/~https://github.com/Consensys/teku/issues/7715)
