HSE 2.1 is now available

[hse-root]

We are pleased to announce the release of HSE 2.1.

Summary of Changes

HSE now supports persistent memory (pmem) as a media class, either standalone or combined with media classes based on block storage. Data in a pmem media class is accessed directly via load and store instructions.

Introspection APIs were added for querying KVDB and KVS configuration information. This makes it easier for HSE applications to manage KVDBs and validate their configuration.

Cursor APIs were extended to optionally iterate over keys without retrieving values, and to optionally return keys or values in client-provided buffers.

Python language bindings were updated for the API changes noted above.

HSE now runs on the s390x architecture, in addition to x86_64. Note that our s390x testing and performance tuning is limited due to resource constraints.

We further streamlined the build infrastructure, extended test suites, and enhanced CI workflows in GitHub Actions.

Call to Action
