Version 2.1.0 Release

This minor release includes improvements to substation locating, stability and logic fixes. Detailed changes are as follows:

Added

• Add checks for paths between nodes which contain less than one grid point.

Changed

• Change behaviour of devices_per_string input so that the routing algorithm
  runs with only this value when set and not all values up to it.

Fixed

• Fix substation locating algorithm (for single substation).

Version 2.0.0 Release

This release coincides with the release of DTOcean 2.0.

The following changes were made:

Added

• Re-implement constraints recording and plotting.
• Add change log.
• Add example which uses pickled inputs exported from dtocean-core.
• Added edge_buffer option to ConfigurationOptions class to ensure substation
  is located a certain distance away from the lease area edge.
• The selected export cable voltage is now returned with the outputs.

Changed

• Changed grid processing to improve methodology for joining lease area and
  cable corridor.
• Excluded grid points are now removed from Grid.grid_pd and Grid.points as
  well as Grid.graph.
• Emit a nx.NetworkXNoPath error in the optimiser if there are no point in the
  selected tool's graph.
• Made calls to Dijkstra's shortest path algorithm more efficient for radial
  networks.
• Accelerated grid distance and gradient processing by converting parts of the
  grid DataFrame to numpy arrays and reorganising other DataFrame manipulation.
• Changed networkx single_source_dijkstra function call to match 2.0 API.
• Optimise by lowest cost per power transmitted, rather than just cost.
• Allow array rated powers above the maximum scope to be calculated, but still
  raise a warning.
• Array and export cable databases are now provided as separate inputs.

Removed

• Removed incorrect catch for KeyErrors when searching for cable routes.

Fixed

• Replaced incorrect Shapely object when calculating design limits.
• Fixed issue where bathymetry points would be excluded if the local gradient
  exceeded 0. This now conforms to the user set limit.
• Fixed issue with the substation location algorithm, when devices where in
  symmetric layouts.
• Fixed bug with checking soil types.
• Use power histogram bin centres for power calculations rather than edges.
• Add missing soil types for setting burial protection index.
• Ensure all Grid attributes are referenced by the point "id".
• Fixed Network.make_cable_routes so that cable points are returned in the
  correct order.
• Improved algorithm for determining the grid spacing.
• Ensured that umbilical cable paths are correctly joined to the inter-arrays
  cables.
• Fixed approximation of umbilical cable termination point when path only has
  one point.
• Fixed umbilical cable length calculation by changing device rotation frame
  from global to local coordinates.
• Improved speed of umbilical calculation.
• Ensure that the burial depth can be calculated if cable paths intersect.
• Fixed issue where umbilical cables would incorrectly reduce the static cable
  lengths.
• Improved memory efficiency for grid processing.
