I am very happy to announce the release of buildbot 0.9.1.

One month after 0.9.0 its time to release 0.9.1.
As we had a very long stabilization period for 0.9.0, 0.9.1 actually
contains features that were brought to master branch since August 2016.
For the next releases we will go back to a faster release rate, probably
one per month.

The big change for this release is the rework of the LatentWorker framework.

Latent worker are workers that are started on demand.
They have lot of advantages:

- Optimization of resource costs
- Better reproducibility: Worker can always restart from a clean fresh new

LatentWorker changes are:

- Latent workers can now start in parallel
- Latent workers life cycle is now much better, lot of work has been done
to ensure workers are stopped when not needed anymore (project funded by
Mozilla MOSS
- Support for the Container As a Service provider (Used in
production for buildbot community CI)
- Enhancements for the OpenStack LatentWorker (Used in production by
skelly, one of core team member)
- Introduction of a worker quarantine to avoid reusing a worker that cannot

Although it is not yet finished, lots of efforts have been done to improve
the python3 compatibility. Thanks to Craig Rodrigues for driving this.
Other noticable changes are big improvements for the nine version of the
MailNotifier. Thanks to benallard for driving this.

There are also lots of small and medium contributions from the community,
improvements of documentation, sometimes by new contributors showing us
that the nine framework is more and more adopted.
Please continue flooding us with patches, we love that!

As usual the release notes are available within our documentation
