v0.8.0

SMQTK v0.8.0 Release Notes

This minor release represents the merger of a public release request that added a
Girder-based implementation of the DataElement interface. We also optimized the
use of the PostgreSQL DescriptorIndex implementation to use named cursors for
large queries.

Updates / New Features since v0.7.0

Data Structures

• Revise GirderDataElement to use girder_client python module and added the
  the use of girder authentication token values in lieu of username/password
  for communication authorization.

• Add the optional use of named cursors in PostgreSQL implementation of the
  DescriptorIndex interface. Assists with large selects such that the server
  only sends batches of results at a time instead of the whole result pool.

• Added PostgreSQL implementation of the KeyValueStore interface.

Girder

• Initial SMQTK Girder plugin to support image descriptor processing via
  girder-worker.

• Initial SMQTK Girder plugin implementing a resource and UI for SMQTK nearest
  neighbors and IQR.

Fixes since v0.7.0

Data Structures

• Added locking to PostgreSQL DescriptorElement table creation to fix race
  condition when multiple elements tried to create the same table at the same
  time.

• Fix unconditional import of optional girder_client dependency.

Dependencies

• Pinned Pillow version requirement to 4.0.0 due to a large-image conversion
  issue that appeared in 4.1.x. This issue may have been resolved in newer
  versions of Pillow.

Scripts

• Various fixes to IQR model generation process due to changes made to
  algorithm input parameters (i.e. taking DataElement instances instead of
  filepaths).

• Fixes build_iqr_models.sh to follow symlinks when compiling input image
  file list.

Tests

• Fix missing abstract function override in KeyValueStore test stub.

• Fix test girder_client.HttpError import issue.
