We are excited to announce that YugabyteDB 2.1.3 is GA! You can read the official release notes here. This release shipped with over 60 new enhancements and fixes.

The Yugabyte team has been working from home in order to do our part with social distancing and to help with containment efforts. We have also transitioned to online meetings with our customers, partners, candidates, community, and fellow Yugabeings. We will continue with these and other measures until it’s determined to be safe otherwise. We wish everyone the best health and wellness, and our thoughts are with all those around the world who have been affected by COVID-19. If during these unprecedented circumstances, you have some time or would welcome a brief distraction, we invite you to check out this post below.

What’s YugabyteDB? It is an open source, high-performance distributed SQL database built on a scalable and fault-tolerant design inspired by Google Spanner. YugabyteDB’s SQL API (YSQL) is PostgreSQL wire compatible.
