stellar/stellar-core v19.9.0

on GitHub

This release contains some stability improvements and enables serializing BucketListDB indexes on disk.

Stability improvements

• Tests: allow overlay to work automatically in loopback mode

New features

• Serialize indexes to disk
  This change saves BucketListDB indexes on disk, so validators can load the index files, instead of reindexing the entire BucketList on startup. On EBS, indexing the BucketList takes about 4 minutes, but loading indexes takes about 1-2 seconds only.
