Release notes for DSE 6.8.8

15 December 2020

⚠️ NOTE: Due to a serious bug which affects DSE 6.8.7 and DSE 6.8.8, these releases have been retracted. We recommend against upgrading to these versions at this time. If you have already upgraded to these versions, please EITHER set zerocopy_streaming_enabled=false in the cassandra.yaml and perform a rolling restart AND/OR run upgradesstables on all nodes in your cluster before adding new nodes, running repair, or restoring from backups. This bug has been addressed in DSE 6.8.9. All features and fixes for 6.8.8 and 6.8.7 are present in 6.8.9.

When this happens, all flushing of indexes involved in this transaction is aborted and the indexes are marked non-queryable. Recovering from this issue involves either rebuilding the indexes or restarting the nodes. (DSP-21580)
