OpenSearch Software Foundation Enhances Enterprise Capabilities with New LTS Program

On April 16, 2026, during the OpenSearchCon Europe event, the OpenSearch Software Foundation announced a significant development for enterprises looking to enhance their search infrastructure. The foundation introduced its Long-Term Support (LTS) program, aimed at providing a reliable and well-supported open-source platform for enterprise search and analytics, scalability, and observability.

As organizations increasingly adopt open-source solutions in their infrastructure, they seek the dual advantages of flexibility and stability. According to a report from the Linux Foundation Research, enterprises that leverage open-source tools can achieve a return on investment of 2 to 5 times compared to proprietary alternatives. OpenSearch already provides substantial value to companies like Atlassian and Uber, and the new LTS program is set to expand these benefits to a wider range of users with accredited vendor support and improved stability.

Key Features of the LTS Program:

The LTS program guarantees specific support lifecycles for each major version, beginning with OpenSearch 2.1.9 and 3.6. The 18-month support period ensures that enterprises can rely on a secured and stable environment without being locked into a single vendor. This vendor-neutral approach allows users to engage with accredited vendors who meet Foundation-approved standards for providing commercial LTS offerings, ensuring customers have access to professional support worldwide.

"This program is a timely response to an increasing need for dependable, production-grade support solutions that adhere to open-source principles," stated Bianca Lewis, executive director of the OpenSearch Software Foundation. "Long-term support versions provide predictable backing, trusted security practices, and certified vendor options, alleviating fears about deploying OpenSearch in sensitive environments."

In pursuit of regulatory compliance and risk management, the OpenSearch foundation will leverage scanning across the approximately 150 OpenSearch repositories. By creating a Software Bill of Materials (SBOM), organizations can confidently validate the security and provenance of their OpenSearch deployments, addressing vulnerabilities with medium and high severity issues within 60 days of discovery.

First Long-Term Support Providers

The initial LTS providers that have received accreditation include BigData Boutique, Eliatra, and Resolve Technology. They offer services that include:

• - Stability: Each major version of OpenSearch will have at least one designated LTS version supported for a minimum of 18 months.
• - Transparent security posture: A commitment to promptly address vulnerabilities and ensure early notifications of security issues.
• - Accreditation: Vendors who meet specific standards can deliver LTS offerings while ensuring that improvements are shared back with the community, maintaining a holistic and open development approach.

This new long-term support initiative is expected to aid enterprises that run mission-critical and AI-driven workloads on OpenSearch. Its aim is not just about promise but to provide tangible, operational security and excellence.

Enhanced Features in OpenSearch 3.6

The launch of OpenSearch 3.6 as the first LTS version introduces advanced AI-driven search capabilities alongside a unified observability stack. This further strengthens the platform's ability to handle complex, distributed systems effectively while maintaining transparency and control for IT administrators.

Jan Erik Aase, a partner and global head at ISG, emphasized the importance of unifying observability, search, and AI execution into a cohesive layer, allowing enterprises to innovate more quickly while retaining insight at scale.

Join the OpenSearch Movement

Organizations wishing to provide LTS services can become part of the OpenSearch Software Foundation and apply for vendor accreditation through the foundation's certification program available at opensearch.org/long-term-support. Those interested in learning more about the latest capabilities in OpenSearch 3.6 can explore the release blog for extensive details.

This strategic move marks a significant evolution in the enterprise open-source landscape, one where credible support and proven technology coexist, ensuring firms can deploy their applications robustly and responsibly. The OpenSearch Software Foundation continues to drive towards long-term innovation in search and analytics, aiming to keep the community engaged and growing for years to come.
