 ## [unreleased]
 
 ### Protocol Changes
-**No Changes**
+* Sets `chunk_validator_only_kickout_threshold` to 70. Uses this kickout threshold as a cutoff threshold for contribution of endorsement ratio in rewards calculation: if endorsement ratio is above 70%, the contribution of endorsement ratio in average uptime calculation is 100%, otherwise it is 0%. Endorsements received are now included in `BlockHeader` to improve kickout and reward calculation for chunk validators. 
 
 ### Non-protocol Changes
 * Added [documentation](./docs/misc/archival_data_recovery.md) and a [reference](./scripts/recover_missing_archival_data.sh) script to recover the data lost in archival nodes at the beginning of 2024.
