v0.4.1

• Added the ability to color nodes and edges in xgi.draw() by value, iterable, or NodeStat/EdgeStat (#139, #142, and #143).
• Fixed the distortion of the node aspect ratio with different figure sizes in Issue #137.
• Moved the isolates() and singletons() method from the Hypergraph class to the NodeView and EdgeView classes respectively (#146).
• Fixed Hypergraph.copy() to not use the subhypergraph method (#145).
• filterby() now accepts NodeStat and EdgeStat objects instead of just strings (#144).
• Removed edit-mode install to run the Github Actions test suite (#136).
• Added unit tests (#147).

v0.4

• Added the stats package which implements NodeStat, EdgeStat and related functionality. This package now handles computation of edge size and degree (#120).
• Removed the EdgeSizeView and DegreeView classes (#120).
• Changed all imports to be relative in the xgi package (#121).
• Added an assortativity module (#122).
• Improved the performance of accessing edge members (#124).
• Added more operations for node and edge attributes besides "eq" (#125).
• Added a function to convert all node and edge labels to integers and store the old labels as properties (#127).
• Renamed the egonet method to `edge_neighborhood (#129).
• Moved the neighbors method in the Hypergraph class to the IDView class so that node and edge neighbors are now supported (PR #129).
• Added a centrality module and added these methods to nodestats.py and edgestats.py (#130).
• Moved the load_xgi_data method to the readwrite module (#130).
• Added a generator for sunflower hypergraphs (#130).
• Added a Jupyter notebook as a quickstart guide (#131 and #134).
• Fixed a bug in the barycenter_spring_layout and weighted_barycenter_spring_layout methods to handle non-integer node IDs (#133).
• Added an isort configuration file so it no longer sorts the __init__.py files (#134).

v0.3.1

• Refactored the subhypergraph methods
• Moved functions no related to the core Hypergraph data structure to functions.py
• Removed unnecessary duplicated functions (n_bunch_iter, get_edge_data, and has_node)
• Refactored the members() method as well as the NodeView and EdgeView classes for significant speedup.
• Github Actions now tests the docstrings and tutorial notebooks
• The add_edges_from method now supports different input formats.
• Fixed various bugs in the generative models module.
• A method for double edge swaps is now implemented.

v0.3

• Added the ability to convert to and from a NetworkX bipartite graph.
• Removed the shape property from Hypergraph and renamed the number_of_nodes() and number_of_edges() methods to the num_nodes and num_edges properties, respectively.
• Added random seed decorator as in NetworkX.
• Added a SimplicialComplex class.
• Added order and weighted arguments to the incidence_matrix and adjacency_matrix functions.
• Added an intersection_profile function.
• Added a laplacian function with argument order and a multiorder_laplacian function.
• Fix: Return an empty array rather than a 1x1 zero array when appropriate.
• Fix: Ensured that the incidence matrix is always has dimensions num_nodes x num_edges.
• Added 2 generators of random (maximal) simplicial complexes, and toy star-clique generator
• Extensively rewrote the documentation, updating the content and format on Read The Docs.
• Added an egonet function to get the edges neighboring a specified node.
• Added functions to visualize hypergraphs and simplicial complexes.
• Added the ability to get nodes and edges of given degrees/sizes respectively.
• Extended the members() function to be able to get different data types and to either get a single edge or all edges.
• Added the load_xgi_data function to load datasets from the xgi-data repository.
• Added two additional tutorials: a tutorial on visualizing higher-order networks and a case study replicating a recent paper.
• Changed the API of degree_histogram and added degree_counts based on #23.
• Refactored the IDDegreeView class and changed the API. Added the ability to specify order and the datatype.
• Added an abstract class IDDict to handle data validation.

v0.2

• H[attr] now accesses hypergraph attributes
• H.nodes[id] now accesses attributes, not bipartite neighbors
• Removed the__call__() functionality from H.nodes and H.edges
• H.nodes.memberships(id) and H.edges.members(id) now access the bipartite neighbors
• Created base classes for the Node/Edge Views and Degree/Edge Size Views to inherit from.
• Removed the NodeDataView and EdgeDataView.
• Updated the list of developers
• __getitem__() in the NodeView and EdgeView are now in a try-except block for greater efficiency.
• Removed the name attribute and fixed methods and tests to match.
• Fixed the erdos_renyi_hypergraph(), chung_lu_hypergraph(), and dcsbm_hypergraph() methods such that the number of nodes will always match the number the user specifies, even if the resulting hypergraph is disconnected.
• Changed the construction method from reading in a Pandas DataFrame to using the add_node_to_edge() method for a 2x speedup.
• Added some basic unit tests for the generative models.
• Added the dual keyword for the read_bipartite_edgelist() method.
• Added small functions to the Hypergraph class
