Versioning and availability in Elastic Docs
Learn how Elastic Docs handles versioning, feature availability, and how to find the right documentation for your deployment type and product version. Find answers to common questions about the Elastic Stack versioning and confidently navigate our continuously updated documentation.
You’re in the right place! All documentation for Elastic Stack 9.0.0 and later is available at elastic.co/docs, including the latest 9.1 version and any future versions in the 9.x series.
Need docs for an earlier version? Go to elastic.co/guide.
Starting with Elastic Stack 9.0.0, Elastic no longer publishes separate documentation sets for each minor release. Instead, all changes in the 9.x series are included in a single, continuously updated documentation set.
This approach helps:
- Reduce duplicate pages
- Show the full history and context of a feature
- Simplify search and navigation
We clearly mark content added or changed in a specific version using availability badges. The availability badges appear in page headers, section headers, and inline.
Stack
This means the feature is:
- Available on Elastic Stack
- Generally Available (GA)
- Introduced in version 9.1.0
Serverless Elasticsearch Serverless Security
This means the feature is:
- Generally Available for Elasticsearch Serverless projects
- Beta for Elastic Security Serverless projects
ECE
This means the feature is:
- Available on Elastic Cloud Enterprise
- Deprecated starting in version 4.1.0

Documentation for Elastic Stack 8.19.0 and earlier is available at elastic.co/guide.
If a previous version for a specific page exists, you can select the version from the dropdown in the page sidebar.
We frequently update Elastic Docs to reflect the following:
- Minor versions, such as Elastic Stack 9.1.0
- Patch-level updates, such as Elastic Stack 9.1.1
- Ongoing improvements to clarify and expand guidance
To learn what's changed, check the release notes for each Elastic product.
To make sure you're always viewing the most up-to-date and relevant documentation, the version dropdown at the top of each page shows the most recent 9.x release. For example, 9.0+.
Elastic Stack uses semantic versioning in the X.Y.Z format, such as 9.0.0.
| Version | Description |
|---|---|
| Major (X) | Indicates significant changes, such as new features, breaking changes, and major enhancements. Upgrading to a new major version may require changes to your existing setup and configurations. |
| Minor (Y) | Introduces new features and improvements, while maintaining backward compatibility with the previous minor versions within the same major version. Upgrading to a new minor version should not require any changes to your existing setup. |
| Patch (Z) | Contains bug fixes and security updates, without introducing new features or breaking changes. Upgrading to a new patch version should be seamless and not require any changes to your existing setup. |
Understanding Elastic Stack versioning is essential for upgrade planning and ensuring compatibility.
The features available to you can differ based on deployment type, product lifecycle stage, and specific version.
| Factor | Description |
|---|---|
| Deployment type | The environment where the feature is available, for example, Elastic Stack, Elastic Cloud Serverless, Elastic Cloud Enterprise (ECE), Elastic Cloud on Kubernetes (ECK) |
| Lifecycle state | The development or support status of the feature, for example, GA and Beta |
| Version | The specific version the lifecycle state applies to |
| Lifecycle state | Description |
|---|---|
| Generally Available (GA) | Production-ready feature. When unspecified, GA is the default |
| Beta | Feature is nearing general availability but not yet production-ready |
| Technical preview | Feature is in early development stage |
