# Versioning
|
|
|
|
## API
|
|
ONNX Runtime follows [Semantic Versioning 2.0](https://semver.org/) for its public API.
|
|
Each release has the form MAJOR.MINOR.PATCH, adhering to the definitions from the linked semantic versioning doc.
|
|
|
|
## Current stable release version
|
|
The version number of the current stable release can be found
|
|
[here](../VERSION_NUMBER).
|
|
|
|
## Release cadence
|
|
See [Release Management](ReleaseManagement.md)
|
|
|
|
# Compatibility
|
|
|
|
## Backwards compatibility
|
|
All versions of ONNX Runtime will support ONNX opsets all the way back to (and including) opset version 7.
|
|
In other words, if an ONNX Runtime release implements ONNX opset ver 9, it'll be able to run all
|
|
models that are stamped with ONNX opset versions in the range [7-9].
|
|
|
|
|
|
### Version matrix
|
|
The [table](https://onnxruntime.ai/docs/reference/compatibility.html#onnx-opset-support) summarizes the relationship between the ONNX Runtime version and the ONNX opset version implemented in that release.
|
|
Please note the backward compatibility notes above.
|
|
For more details on ONNX Release versions, see [this page](https://github.com/onnx/onnx/blob/main/docs/Versioning.md).
|
|
|
|
## Tool Compatibility
|
|
A variety of tools can be used to create ONNX models. Unless otherwise noted, please use the latest released version of the tools to convert/export the ONNX model. Most tools are backwards compatible and support multiple ONNX versions. Join this with the table above to evaluate ONNX Runtime compatibility.
