+Tern is an open source project with limited resources. In 2023 we will primarily focus on bug fixing and step back from active feature development with the exception of adding SPDX generation to Tern using the [spdx-tools](https://pypi.org/project/spdx-tools/) library instead of the in-house SPDX model.
 
 We will continue to support the SPDX format for container images. To that end, we will make changes to update the format of the document as the [spec](https://spdx.github.io/spdx-spec/) evolves.
