v0.7.0

Major changes in this release

• Support for importing data without a primary key. Since the Sno model requires that every feature has a primary key, primary keys are assigned during import. #212
• Support for checking out a dataset with a string primary key (or other non-integer primary key) as a GPKG working copy. #307

Minor features / fixes:

• Improved error recovery: Sno commands now write to the working copy within a single transaction, which is rolled back if the command fails. #281
• Dependency upgrades (GDAL; Git; Pygit2; Libgit2; Spatialite; GEOS) #327
• Bugfixes:
  • sno meta set didn't allow updates to schema.json
  • Fixed a potential KeyError in Schema._try_align
  • Fixed a potential unexpected NoneType in WorkingCopy.is_dirty
  • Imports now preserve fixed-precision numeric types in most situations.
  • Imports now preserve length of text/string fields.
  • Imported fields of type numeric now stored internally as strings, as required by datasets V2 spec. #325
