Changelog

This file summarizes notable changes introduced in aktualizr version. It roughly follows the guidelines from Keep a Changelog.

Our versioning scheme is YEAR.N where N is incremented whenever a new release is issued. Thus N does not necessarily map to months of the year.

[upcoming release]

[2020.10] - 2020-10-27

Added

  • Updated the garage-push and garage-deploy tools. Now, they support new back-end token generation to authenticate API requests. Also, we updated the treehub.json format for the new back-end. It now has the additional scope parameter. The changes are backward compatible. Previous versions have the server URL without the token path, so it needs to be hardcoded. The new version has the full URL with the /oauth2/token path at the end: PR

Changed

  • Ubuntu Focal Dockerfile now uses the default OSTree package: PR
  • Improved libaktualizr API exceptions: PR
  • Improved binary file download progress: PR
  • Allowed passing HTTP headers in aktualizr-get: PR
  • Moved aktualizr-lite to its own aktualizr-lite repository: PR

Fixed

  • Fixed the issue with the parameters check in aktualizr-get: PR
  • Fixed the output of the pacman configuration: PR

[2020.9] - 2020-08-26

Added

  • Exceptions thrown through the API are now documented: PR
  • The client TLS certifcate and key can be re-imported from the filesystem as long as the device ID is unchanged: PR

Changed

  • More required headers for libaktualizr usage have been refactored for easier use: PR
  • All code is now checked with clang-tidy-10: PR
  • Default/recommended Yocto branch is dunfell (3.1): PR

Removed

  • The Debain package manager has been removed as it was never fully functional: PR
  • Android support has been removed as it was an unfinished prototype: PR
  • The ISO-TP Secondary has been removed as it was an unmaintained prototype: PR

[2020.8] - 2020-07-09

Special considerations

As a result of changes to the IP/POSIX Secondary protocol (see below), users of these Secondaries will need to take special care when upgrading their devices. The new version of aktualizr is backwards compatible and will work with both old and new versions of the protocol. However, aktualizr-secondary is not. This means that if you are upgrading a device with IP/POSIX Secondaries, you should update the Primary ECU running aktualizr first, and if that is successful, then update your Secondaries.

Added

  • You can now use the SetInstallationRawReport API function to set a custom raw report field in the device installation result: PR
  • You can now re-register ECUs, which supports replacing the Primary and adding, removing, and replacing Secondaries: PR
  • gcc version 9 is now supported: PR

Changed

  • Improved the Secondary interface and error reporting: PR
  • Improved the Secondary IP/POSIX communication protocol, including streaming binary updates from the Primary to the Secondary: PR
  • Moved the binary update logic to the package manager (and added images_path to the configuration): PR
  • The shared provisioning p12 file is now removed from the credentials archive after use. This can be disabled for testing. PR
  • Errors encountered while sending metadata to Secondaries are now reported to the server with greater detail: PR
  • The headers required to include for API users have been simplified: PR #1707, PR #1713, and PR #1716

[2020.7] - 2020-05-29

Changed
