Highlights

This is a major refactor release with WebSockets for internal communication between nodes. We advise our users to follow our upgrade instructions on best practices

• Click here to download the latest version of MinIO.
• Click here for production support.
• This release brings a larger change to internode communication, which is now re-implemented to use WebSockets for most of the internal calls. Allowing us much larger scalability to 100s to 1000s of nodes. To learn more about the WebSockets grid implementation please read.
• Site replication now supports optionally heal ILM configuration to all sites, allowing ILM settings across buckets to be centrally managed via any site.
• Batch replication from minio -> minio ultimately uses compressed archive by default to more effectively utilize the bandwidth during batch replication.
• Batch expiration of objects on your MinIO instance.
• MinIO now also supports external caching for metadata calls such as HeadObject() in a distributed memory for faster lookups when you have a slower medium such as HDD and a READ-heavy workload pattern.
