Currently, there are many major functions in SRS, such as:

• Live RTMP: 3.0 stable version, 4.0 stable version, 5.0 stable version.
• Live HLS: 3.0 stable version, 4.0 stable version, 5.0 development version.
• Live HDS: 4.0 deprecated version, will be removed in 5.0.
• Live DVR recording: 3.0 stable version, 4.0 stable version, 5.0 development version.
• Live Origin server cluster: 3.0 stable version, 4.0 stable version, 5.0 development version.
• Live Edge server cluster: 3.0 stable version, 4.0 stable version, 5.0 stable version.
• Communication RTC: 4.0 development version, 5.0 development version.
• RTC to RTMP conversion: 4.0 development version, 5.0 development version.
• RTMP to RTC conversion: 4.0 development version, 5.0 development version.
• RTC cluster: 5.0 development version.
• RTC Simulcast: 5.0 development version.
• GB28181: 4.0 development version, 5.0 development version.
• SRT: 4.0 development version, 5.0 development version.
• Windows: 5.0 development version.
• ......

These features have stability and lifecycle changes with different versions. If you carefully review the relevant information, you can know the status of each feature. However, this approach has a high threshold and is cumbersome. Why not provide an API query like the stable version query on the official website?

For example, when SRS starts, it not only includes its own version but also the features it has enabled.

HTTP/HTTPS GET https://api.ossrs.net/service/v1/releases?docker=1

When querying the version, the currently enabled feature (docker=1) has also been added. In the response, the corresponding status of the feature is returned ("docker":"stable").

Response
{
"docker": "stable"
}

This makes it convenient to know the status of the desired feature in the corresponding version.
