Changelog

v5.0.0

This release, most notably, marks stable securesystemslib v1.0.0 as minimum requirement. The update causes a minor break in the new DSSE API (see below) and affects users who also directly depend on securesystemslib. See the securesystemslib release notes and the updated python-tuf examples (#2617) for details. ngclient API remains backwards-compatible.

Changed

  • DSSE API: change SimpleEnvelope.signatures type to dict, remove SimpleEnvelope.signatures_dict (#2617)
  • ngclient: support app-specific user-agents (#2612)
  • Various build, test and lint improvements

v4.0.0

This release is a small API change for Metadata API users (see below). ngclient API is compatible but optional DSSE support has been added.

Added

  • Added optional DSSE support to Metadata API and ngclient (#2436)

Changed

  • Metadata API: Improved verification functionality for repository users (#2551):
    • This is an API change for Metadata API users ( Root.get_verification_result() and Targets.get_verification_result() specifically)
    • Root.get_root_verification_result() has been added to handle the special case of root verification
  • Started using UTC datetimes instead of naive datetimes internally (#2573)
  • Constrain securesystemslib dependency to <0.32.0 in preparation for future securesystemslib API changes
  • Various build, test and lint improvements

v3.1.1

This is a security fix release to address advisory GHSA-77hh-43cm-v8j6. The issue does not affect tuf.ngclient users, but could affect tuf.api.metadata users.

Changed

  • Added additional input validation to tuf.api.metadata.Targets.get_delegated_role()

v3.1.0

Added

  • Metadata API: move verify_delegate() to Root/Targets (#2378)
    • verify_delegate() on Metadata is now deprecated
  • Metadata API: add get_verification_result() as verbose alternative for verify_delegate() (#2481)
  • Metadata API: add MetaFile.from_data() convenience factory (#2273)

Changed

  • Metadata API: change Root.roles type hint to Dict (#2411)
  • Various minor improvements in tests (#2447, #2491), docs (#2390, #2392, #2474) and build (#2389, #2453, #2479, #2488)

Removed

  • build: Python 3.7 support (#2460)

v3.0.0

The notable change in this release is #2165: The tuf.api.metadata.Key class implementation was moved to Securesystemslib with minor API changes. These changes require no action in tuf.ngclient users but may require small changes in tuf.api.metadata using repository implementations that create keys.

As a result of these changes, both signing and verification are now fully extensible, see Securesystemslib signer API for details.

tuf.repository remains an unstable module in 3.0.0.

Added

  • Build: Use pydocstyle to lint docstrings (#2283, #2281)
  • Examples: Add Repository uploader/signer tool example (#2241)
  • Metadata API: Add TargetFile.get_prefixed_paths() (#2166)
  • ngclient: Export TargetFile (#2279)
  • repository: Add strictly typed accessors and context managers (#2311)
  • Release: Use PyPI Trusted Publishing https://docs.pypi.org/trusted-publishers/ (#2371)

Changed

  • Build: Various minor build and release infrastructure improvements, dependency updates
  • Metadata API: Key class is still part of the API but now comes from Securesystemslib (#2165):
    • Key.verify_signature() method signature has changed
    • Key.from_securesystemslib_key() was removed: Use Securesystemslibs SSlibKey.from_securesystemslib_key() instead

  • workflow: misc improvements (#2001, #2092, #2147, #2159, #2173)

v2.0.0

This release, most notably, adds support for TAP 15 - succinct hash bin delegation, which results in a few backwards-incompatible changes in the Metadata API.

NOTE: While TAP 15 has been accepted it is not yet part of the TUF specification. Therefore, adopters should be prepared for potential changes to the implementation in future and for a lack of support for TAP 15 in other TUF implementations.

v0.19.0

For users of legacy client (tuf.client module) this is purely a security fix release with no API or functionality changes. For ngclient (tuf.ngclient) and Metadata API (tuf.api.metadata), some API changes are included.

All users are advised to upgrade.

Note that python-tuf has required python>=3.5 since release 0.18.0.

Fixed

  • GHSA-wjw6-2cqr-j4qr: Fix client side issue in both legacy client (tuf.client) and ngclient (tuf.ngclient) where a malicious repository could trick client to overwrite files outside the client metadata store during a metadata update. The fix includes percent-encoding the metadata rolename before using it as part of a filename https://github.com/theupdateframework/python-tuf/security/advisories/GHSA-wjw6-2cqr-j4qr
  • ngclient: Do not use urljoin to form metadata URL (included in GHSA-wjw6-2cqr-j4qr)
  • ngclient: Persist metadata safely (#1574)
  • ngclient: Handle timeout on session.get() (#1588)

v0.18.1

Changed

  • Update setup.cfg to not build universal wheels (#1566)

v0.18.0

0.18 is a big release with 3 main themes:

  • Support only Python 3 and modernize the infrastructure accordingly
  • Metadata API (a low-level API for metadata de/serialization and modification) is now feature-complete for the client use cases
  • ngclient (a new high-level client API) was added. ngclient should be considered an unstable API and is not yet recommended for production use.

Additionally the Github project name changed: project is now "python-tuf" instead of "tuf". Redirects are in place for the old name but updating links is advised.

Added

  • Add ADR6: Where to implement serialization (#1270)
  • Add ADR8: Unrecognized fields (#1343)
  • Add ADR9: Refine reference implementation purpose (#1554)

v0.17.0

NOTE: this will be the final release of tuf that supports Python 2.7. This is because Python 2.7 was marked end-of-life in January of 2020, and since then several of tuf's direct and transient dependencies have stopped supporting Python 2.7.

Added
