# Release 2.6.1

## Summary
This release includes the usual mix of features, bug fixes and resolved technical debt. Namely, this release adds the ability to inventory a container at build time. When paired with other container build tools, this feature makes it possible to package and distribute the container SBoM with a container image, which eliminates the need for post-build scanning. Additionally, default reports were reformatted to better organize and display package metadata in a table instead of a list which makes it easier to associate licenses found in the container with the packages they belong to. 

A number of bugs were also resolved in this release. Most importantly, Tern now properly collects and reports on file information from Scancode, drastically improving the accuracy of the reports generated with Tern + Scancode. Tern's run time performance has also improved significantly with the removal of regex based filtering in some files.

NOTE: Due to human error, we had to bump the intended 2.6.0 release version to version 2.6.1. This doesn't change the contents of the release.

## New Features
* [Generate SBoMs at container build time](https://github.com/tern-tools/tern/issues/849): This feature enables Tern to inventory and generate an SBoM against a mounted container filesystem. This feature is meant to work along with other container build tools and scripts. 
* [Display layer packages in a table format](https://github.com/tern-tools/tern/issues/930): The default report now represents package metadata in a formatted table instead of a list. This makes the reports cleaner and easier to understand.
* [Add copyright info for NPM packages](https://github.com/tern-tools/tern/issues/957): Tern can now provide copyright information for NPM packages in the JSON, YAML, HTML and SPDX reports.

## Bug Fixes
* [Scancode not producing file or file license info](https://github.com/tern-tools/tern/issues/959)
* [AttributeError when using debug subcommand](https://github.com/tern-tools/tern/issues/967)
* [Infinite notices are reported](https://github.com/tern-tools/tern/issues/942)
* [Scancode errors when collecting pip package information](https://github.com/tern-tools/tern/issues/964)

## Resolved Technical Debt
* [Remove regex based filtering to increase run performance](https://github.com/tern-tools/tern/issues/939)
* [Add 'Understanding the Reports' section to README](https://github.com/tern-tools/tern/issues/960)
* [Update 'debut' dependency to reflect new 'debian-inspector' name](https://github.com/tern-tools/tern/issues/961)
* [Use dpkg-query to avoid using cut and awk utilities](https://github.com/tern-tools/tern/issues/936)

## Future Work
* Enable Dockerfile "locking" for multistage docker builds
* Use skopeo to pull container images
