You can find release notes for all releases in the release-notes directory, in markdown and JSON formats. This content is licensed for broad use.
Patch releases are published monthly, often including fixes for vulnerabilities (AKA CVEs) that are disclosed at the same time.
Release notes include:
- Links to binaries
- Notable changes, including CVEs
- Compatibility information
- Updated packages
Example markdown files:
Example JSON files:
releases-index.json and all the files it references are stored in blob storage and in GitHub. We use GitHub for easy discoverability of the files and Azure Blob Storage as our production platform.
It is straightforward to programmatically transform the blob storage links to raw GitHub links should that be desired.
Note: monthly previews are published in the same way, often on the same day. They are not supported so do not include CVE information. However, Release Candidate releases follow our "Go Live" policy and may include CVE information.
We typically release a preview for the next major version each month. These include detailed feature information.

Preview release notes are always in a preview folder. This approach was adopted so that preview releases do not distract from stable releases once preview releases are no longer relevant.
Supported OS information is published for each major release. This information indicates to users which OSes they can expect an app (or the .NET SDK) to run on for a given .NET version. It also indicates which OSes are supported and when they transitioned to EOL status.
Examples:
OS package information is published for each major release. This information indicates which packages must be installed on a given distro for a .NET app (or the .NET SDK) to run. .NET packages are available for multiple distros, which automatically install all required packages.
