1.8.7

• Cleanup mypy typechecking compliance. (#1266)
• When dataset add operations fail due to lineage issues, the produced error message now clearly indicates that
  the problem was due to lineage issues. (#1260)
• Added support for group-by financial years to virtual products. (#1257, #1261)
• Remove reference to rasterio.path. (#1255)
• Cleaner separation of (experimental) postgis and (stable) postgres drivers, and suppress SQLAlchemy cache warnings. (#1254)
• Prevent Shapely deprecation warning. (#1253)
• Fix DATACUBE_DB_URL parsing to understand syntax like: postgresql:///datacube?host=/var/run/postgresql (#1256)
• Clearer error message when local metadata file does not exist. (#1252)
• Address upstream security alerts and update upstream library versions. (#1250)
• Clone postgres index driver as postgis, and flag as experimental. (#1248)
• Implement a local non-persistent in-memory index driver, with maximal backwards-compatibility
  with default postgres index driver. Doesn't work with CLI interface, as every invocation
  will receive a new, empty index, but useful for testing and small scale proof-of-concept
  work. (#1247)
• Performance and correctness fixes backported from odc-geo. (#1242)
• Deprecate use of the celery executor. Update numpy pin in rtd-requirements.txt to suppress
  Dependabot warnings. (#1239)
• Implement a minimal "null" index driver that provides an always-empty index. Mainly intended
  to validate the recent abstraction work around the index driver layer, but may be useful
  for some testing scenarios, and ODC use cases that do not require an index. (#1236)
• Regularise some minor API inconsistencies and restore redis-server to Docker image. (#1234)
• Move (default) postgres driver-specific files from datacube.index to datacube.index.postgres.
  datacube.index.Index is now an alias for the abstract base class index interface definition
  rather than postgres driver-specific implementation of that interface. (#1231)
• Update numpy and netcdf4 version in docker build (#1229)
  rather than postgres driver-specific implementation of that interface. (#1227)
• Migrate test docker image from datacube/geobase to osgeo/gdal. (#1233)
• Separate index driver interface definition from default index driver implementation. (#1226)
• Prefer WKT over EPSG when guessing CRS strings. (#1223, #1262)
• Updates to documentation. (#1208, #1212, #1215, #1218, #1240, #1244)
• Tweak to segmented in geometry to suppress Shapely warning. (#1207)
• Fix to ensure skip_broken_datasets is correctly propagated in virtual products (#1259)
• Deprecate Rename, Select and ToFloat built-in transforms in virtual products (#1263)
