• Removed the multi_node flag, that is not used anymore

[Michele Simionato (@micheles)]

• Added a command oq postzip to send small calculations to the WebUI
• Added a limit of 1000 sources when disagg_by_src=true
• Internal: fixed oq export input -e zip that was flattening the tree
  structure of the input files in the exported zip archive
• Implemented GMFs amplification
• Introduced the flag approx_ddd to support the old algorithm in
  scenario_damage calculations; it is automatically used for exposures
  with fractional asset numbers

• Modified the server views in order to allow using
  numpy.load(allow_pickle=False) in the QGIS IRMT plugin
• Internal: changed some copy.deepcopy calls into copy.copy in hazardlib

[Michele Simionato (@micheles)]

• Removed implicit intensity_measure_types_and_levels
• Added a check to forbid case-similar headers in the exposures
• Improved the error message in case of CSV exposures with wrong headers
• Reduced the slow tasks issue in event_based/ebrisk with many sites
• Enhanced oq compare to accept a file with the control sites
• Improved the error message for duplicate sites
• Speedup of the ebrisk calculator
• Extended the minimum_intensity feature to the classical calculator
• Solved a memory bug when using the nrcan site term: due to a deepcopy
  the engine could run out of memory in the workers for large site collections
• Added a check to forbid multiple complexFaultGeometry nodes
• Internal: we are now shutting down the ProcessPool explicitly in order
  to support Python 3.8
• Internal: removed the class hazardlib.gsim.base.IPE
• Changed the aggregate loss curves generation to not use the partial
  asset loss table, with a huge memory reduction
• Extended oq check_input to accept multiple files
• Changed the scenario damage calculator to use discrete damage distributions
• Forced the "number" attribute in the exposure must be an integer in the
  range 1..65535, extrema included

OpenQuake Engine 3.8.1

[Michele Simionato (@micheles)]

• Fixed random HDF5 bug in disaggregation calculations
• Fixed memory issue in nrcan15_site_term.p
• Fixed get_duplicates check in the SiteCollection
• Fixed bug in case of MMI (log(imls) -> imls)
