DevRel newsletter — September 2024

Hello from the Elastic DevRel team! In this edition of our newsletter blog, we explore the return of Elasticsearch and Kibana as open source projects as well as our usual update on interesting content and upcoming events.

We're very happy to announce that by adopting AGPL, an OSI-approved open source license, Elasticsearch and Kibana are open source again with the changes planned to take place before the 8.16 release is generally available. 

We'll be introducing the AGPL license as an option for the free portions of the source code that are currently available under the Elastic License 2.0 (ELv2) and SSPL 1.0. With this change, this source code will be available under SSPL 1.0, AGPLv3, and the ELv2, giving you the choice of which license to apply when accessing and using the source code.

What changes for me as a user? You get an additional option for accessing and using the source code of Elasticsearch and Kibana, which is currently dual-licensed.

Otherwise, everything else stays the same — our language clients and Logstash have always been available under the Apache 2.0 license. All existing licenses for Elasticsearch and Kibana stay in place, so you can keep doing everything you do today. This change also doesn’t change the features or pricing of the paid tier.

If you have any questions, be sure to check out the FAQ.

• Inference support for Anthropic’s Claude: We have recently added Anthropic's Claude to the Elasticsearch inference API, enabling Elastic users to connect directly to the Anthropic platform and leverage advanced language models like Claude 3.5 Sonnet via Anthropic's messages API.
