Version 3.0.0

WA3 is a more or less from-scratch re-write of WA2. We have attempted to maintain configuration-level compatibility wherever possible (so WA2 agendas should mostly work with WA3), however some breaks are likely and minor tweaks may be needed.

It terms of the API, WA3 is completely different, and WA2 extensions will not work with WA3 – they would need to be ported into WA3 plugins.

For more information on migrating from WA2 to WA3 please see the Migration Guide.

Not all of WA2 extensions have been ported for the initial 3.0.0 release. We have ported the ones we believe to be most widely used and useful. The porting work will continue, and more of WA2’s extensions will be in the future releases. However, we do not intend to port absolutely everything, as some things we believe to be no longer useful.


If there a particular WA2 extension you would like to see in WA3 that is not yet there, please let us know via the GitHub issues. (And, of course, we always welcome pull requests, if you have the time to do the port yourselves :-) ).

New Features

  • Python 3 support. WA now runs on both Python 2 and Python 3.


    Python 2 support should now be considered deprecated. Python 2 will still be fully supported up to the next major release (v3.1). After that, Python 2 will be supported for existing functionality, however there will be no guarantee that newly added functionality would be compatible with Python 2. Support for Python 2 will be dropped completely after release v3.2.

  • There is a new Output API which can be used to aid in post processing a run’s output. For more information please see Output.

  • All “augmentations” can now be enabled on a per workload basis (in WA2 this was available for instruments, but not result processors).

  • More portable runtime parameter specification. Runtime parameters now support generic aliases, so instead of specifying a73_frequency: 1805000 in your agenda, and then having to modify this for another target, it is now possible to specify big_frequency: max.

  • -c option can now be used multiple times to specify several config files for a single run, allowing for a more fine-grained configuration management.

  • It is now possible to disable all previously configured augmentations from an agenda using ~~.

  • Offline output processing with wa process command. It is now possible to run processors on previously collected WA results, without the need for a target connection.

  • A lot more metadata is collected as part of the run, including much more detailed information about the target, and MD5 hashes of all resources used during the run.

  • Better show command. wa show command now utilizes pandoc and man to produce easier-to-browse documentation format, and has been enhanced to include documentation on general settings, runtime parameters, and plugin aliases.

  • Better logging. The default stdout output is now more informative. The verbose output is much more detailed. Nested indentation is used for different phases of execution to make log output easier to parse visually.

  • Full ChromeOS target support. Including support for the Android container apps.

  • Implemented on top of devlib. WA3 plugins can make use of devlib’s enhanced target API (much richer and more robust than WA2’s Device API).

  • All-new documentation. The docs have been revamped to be more useful and complete.


  • Configuration files config.py are now specified in YAML format in config.yaml. WA3 has support for automatic conversion of the default config file and will be performed upon first invocation of WA3.

  • The “config” and “global” sections in an agenda are now interchangeable so can all be specified in a “config” section.

  • “Results Processors” are now known as “Output Processors” and can now be ran offline.

  • “Instrumentation” is now known as “Instruments” for more consistent naming.

  • Both “Output Processor” and “Instrument” configuration have been merged into “Augmentations” (support for the old naming schemes have been retained for backwards compatibility)
