Release Notes

Upgrade Notes:

  • Upgrading from 0.18 requires issuing a full flush of all the indices in the cluster (curl host:9200/_flush) before shutting down the cluster, with no indexing operations happening after the flush.
  • The local gateway state structure has changed, a backup of the state files is created when upgrading, they can then be used to downgrade back to 0.18. Don’t downgrade without using them.

  • Index Blocks: Add index.blocks.write, index.blocks.read, and index.blocks.metadata settings (#1771)
