 ### Breaking Changes
 - RocksDB database metadata format has changed to be more expressive, the migration of an existing metadata file to the new format is automatic at startup. Before performing a downgrade to a previous version it is mandatory to revert to the original format using the subcommand `besu --data-path=/path/to/besu/datadir storage revert-metadata v2-to-v1`.

 - Receipt compaction will be enabled by default in a future version of Besu. After this change it will not be possible to downgrade to the previous Besu version.
 - PKI-backed QBFT will be removed in a future version of Besu. Other forms of QBFT will remain unchanged. 
 
-### Deprecations
+### Known Issues
+- [Frequency: occasional < 10%] Chain download halt. Only affects new syncs (new nodes syncing from scratch). Symptom: Block import halts, despite having a full set of peers and world state downloading finishing. Generally restarting besu will resolve the issue. We are tracking this in [#6884](https://github.com/hyperledger/besu/pull/6884)
+- [Frequency: occasional < 10%] Low peer numbers. More likely to occur on testnets (holesky and sepolia) but also can occur on mainnet. Symptom: peer count stays at 0 for an hour or more. Generally restarting besu will resolve the issue. We are tracking this in [#6805](https://github.com/hyperledger/besu/pull/6805)
 
 ### Additions and Improvements
