The OpenQuake engine version 2.1.1 ("Hugo Benioff") has been released

[Michele Simionato]

This is a bug fix release. It is meant for users running into errors like this one:

  File "/usr/lib/python2.7/dist-packages/openquake/commonlib/sourceconvert

er.py", line 216, in split_fault_source_by_magnitude

    min_mag=mag, bin_width=src.mfd.bin_width,

AttributeError: 'ArbitraryMFD' object has no attribute 'bin_width'

The bug only happens for source models with an ArbitraryMFD, and only in certain situations,

so unless you don't run into this error you do not need to upgrade. Thanks to Phil Cummins

for the bug report.

This release also fixes a bug  on 32 bit platforms, that manifests itself with this error message:

  File "/usr/lib/python2.7/dist-packages/openquake/hazardlib/site.py", line 478, in _extract_site_param

    return getattr(fsc.complete, name).take(fsc.indices)

TypeError: Cannot cast array data from dtype('int64') to dtype('int32') according to the rule 'safe'

If you are using a 64 bit platform you do not need to upgrade.

You can install/upgrade on all supported platforms (Linux and Windows) by following the

instructions given here:

https://github.com/gem/oq-engine/blob/engine-2.1/README.md

That's all, please let us know if you have any trouble with the upgrade.
