Curator 5 has been released, introducing several new features and changes tailored for Elasticsearch 5.x users while maintaining the previous configuration format for ease of upgrade. Key updates include the addition of a powerful reindex action allowing users to reindex locally or remotely with various filters, alongside a new rollover function that facilitates index management based on specified conditions. Curator 5 also introduces date math in index creation for future timestamped indices, an unset shard routing allocation feature, and a period filter for selecting time-based index blocks. Enhancements have been made to the wait-for-completion functionality, reducing client connection binding for long-running actions, although forceMerge remains an exception due to its inherent characteristics in Elasticsearch. Overall, Curator 5 offers a robust set of tools for efficient index management and improved user experience.
