+We’re excited to announce the release of Milvus 2.5.4, which introduces key performance optimizations and new features such as PartitionKey isolation, Sparse Index with DAAT MaxScore, and enhanced locking mechanisms. A standout highlight of this release is its support for 10,000 collections and 1 million partitions, marking a major milestone for multi-tenant use cases. This version also addresses multiple bugs that improve overall stability and reliability, two of the critical bugs may cause data loss. We encourage you to upgrade or try out this latest release, and we look forward to your feedback in helping us continually refine Milvus!
