See https://github.com/igraph/rigraph/blob/9828d7b11be330f994f07ae93a071b356eced903/src/vendor/cigraph/CHANGELOG.md for a complete changelog, in particular the section "Breaking changes".

Lifecycle

Breaking changes

  • Breaking change: remove tkigraph from {igraph} proper (#1474).
  • Breaking change: Hard-deprecate get.edge() and layout.grid.3d() which have been deprecated for 10 years (#1398).
  • Breaking change: use rlang::arg_match() in igraph.match.arg() (#1165).

In-progress deprecations

We are working towards a more consistent interface, especially as regards function naming: ultimately we want the igraph functions to use snake case.
Please update your scripts and codebases as soon as you can.

  • Deprecate eigen_centrality(scale = ) (#1543).
  • Put deprecation message at the beginning not the end of the similarity functions (#1549).
  • Add independence_number() as an alias of ivs_size() (#1522).
  • Add get_edge_ids() as an alias of get.edge.ids() (#1510).
  • Increase the deprecation signal to a warning for hub.score() and authority.score() both replaced by hits_scores() (#1352).
  • Soft-deprecate erdos.renyi.game() and random.graph.game() (#1509).

Features

C library

New functionality

  • Add p.value and p.precision arguments to fit_power_law() to control the computation of the p-value (#1546, #1386).
  • Add max_degree() (#1403).
  • Add experimental sample_chung_lu() (#1416).
  • Rename methods available for sample_degseq() and add the "edge.switching.simple" method (#1376).
  • Weight support for eccentricity() and radius() (#1211).
  • Add some argument checking to add_shape() (#1478).

More informative errors

  • Export .from() etc. with behavior similar to dplyr::across() (#1436): functions like .from() are meant to be used inside [ but now if an user misuses them, the error is more informative.

Bug fixes

  • Fix including diagonal elements in dense adjacency matrices (#1437).
  • Align the body of graph.lattice() with its replacement make_lattice() (#1439).
  • Use deprecated() as default value for circular argument to make_lattice() (#1431).
  • subgraph_centrality() now ignores edge directions (#1414).
  • Remove unintended type conversions when using disjoint_union() (#1375).
  • Add missing PROTECT() (#1382).
  • Fix reading of LGL and NCOL files (broken in 2.0.0) (#1347).
  • Fixed potential memory leak in R_igraph_community_to_membership2() (#1367).

Documentation

  • Update allcontributors table (#1552).
  • Use mathjax for now (#1538).
  • Improve the manual page of sample_() (#1477).
  • Improve cross-links from make_() manual page (#1476).
  • Update is_separator() documentation based on C docs (#1467).
  • Add DOI to citation (#1450).
  • Improve documentation of normalization methods for laplacian_matrix() (#1420).
  • Fix typos in ?plot.common (@gvegayon) (#1413).
  • Fix sample_degseq() example (#1297).
  • Fix graph_from_adjacency_matrix() examples to avoid warnings (#1302).
  • Replace \dontrun{} with @examplesIf (#1307).
  • Improve sample_gnp() examples.
  • Improve centralization docs.
  • Further clarifications for betweenness() (#1489).
  • Clarify how betweenness with cutoff is normalized.
  • Fix centr_eigen_tmax() docs.
  • Make edge_density() examples relevant.
  • Improve eigen_centrality() documentation.
  • Improved cluster_edge_betweenness() documentation.
  • sample_forestfire() tests and example (#1318).

Developer-facing docs

  • Add slightly tweaked boilerplate CONTRIBUTING.md (#1423).
  • Update troubleshooting document.
  • Use {devtag} for internal function docs (#1507).
  • Make .igraph.progress() and .igraph.status() more internal (#1516).

Internal

  • Prepare for libxml2 depending on bcrypt, use pkg-config (#1556, @kalibera).
