> 
> [PLEASE DISTRIBUTE]
> 
> Dear SAGA-Python Community,
> 
> you have probably already noticed that we have pushed out multiple version
> of saga-python to PyPi in the last three weeks in rapid succession: 0.9.4,
> 0.9.5, 0.9.6, 0.9.7, and 0.9.8.
> 
> While more than half of them are incremental bugfix-releases, there are
> also a great number of new features part of the latest saga-python
> release. Here's a quick overview:
> 
> 1. Resource Package
> -------------------
> 
> SAGA-Python 0.9.8 is the first SAGA implementation to provide the SAGA
> Resource Package API. The resource package abstracts the task of resource
> provisioning, allocation and management and maps well to distributed
> computing concepts like 'cloud computing'/IaaS and 'advanced reservation'.
> The resource package is still work in progress, but some rudimentary
> documentation along with an example can be found here: http://saga-
> project.github.io/saga-python/doc/library/resource
> 
> 2. 'Libcloud' / Amazon EC2 Adaptor
> ----------------------------------
> 
> The first adaptor that implements the new resource package is based on
> Apache 'libcloud' (https://libcloud.apache.org/). It currently supports
> and has been tested with Amazon EC2 cloud services. It allows to
> instantiate new EC2 VMs from any of the images / types available on EC and
> to list and shutdown existing ones. The libcloud adaptor ties in nicely
> with the SSH job adaptor: it allows an application to allocate EC2
> resources and then transparently submit 'jobs' to these resources through
> the same API. A complete example can be found here: http://saga-
> project.github.io/saga-python/doc/adaptors/saga.adaptor.ec2_resource.html
> 
> 3. Callback support for PBS
> ---------------------------
> 
> As the first saga-python adaptor, the PBS adaptor now supports job state
> callbacks as defined in the SAGA GFD.90 specification. This has been a
> long-standing item on the saga wish list as it can potentially simplify
> application development significantly while providing better performance.
> An example how to use callbacks with the PBS adaptor can be found here:
> https://github.com/saga-project/saga-
> python/blob/master/examples/jobs/pbsjob.py. After we get some feedback
> about the current implementation, we plan to add callback support to the
> remaining job adaptors over the next couple of releases.
> 
> We have also updated the saga-python website (http://saga-
> project.github.io/saga-python/), the API documentation (http://saga-
> project.github.io/saga-python/doc) and some of the examples and tutorial
> material.
> 
> The full change log can be found here: https://github.com/saga-
> project/SAGA-Python/blob/master/CHANGES.md.
> 
> A big 'thank you' to everyone who contributed to the - at times painful -
> development and testing efforts over the past couple of weeks. I believe
> that this release really marks the point at which saga-python is not only
> a clean re-implementation of the previous 'saga-cpp' and 'saga-bliss'
> packages, but has also surpassed them in terms of functionality, stability
> and features!
> 
> Please let us know if you encounter any problems with this release or if
> you have suggestions and idea for improvement for future versions of saga-
> ython.
> 
> Best regards,
> Ole
