--------------
## Bug fixes

- Fix obsolete Fortran syntax (#2644).

# igraph 2.3.1
--------------
## Bug fixes

- Fix mismatches between C function signatures and function
  calls. This only affects private functions that are defined but not
  yet used (#2620).

# igraph 2.3.0
--------------
## New features

- Add `make_wheel()` to expose `igraph_wheel()` (#1561, #2409).

- Add `transitive_closure()` function to compute the transitive
  closure of a graph (#1350, #2413).

- Add `invalidate_cache()` (#1387, #2416).

- `graphlet_basis()` returns a list of vertices in the `"cliques"`
  component instead of a raw integer matrix (#2470, #2472).

- `vertices()` now errors on duplicate attribute names (#1248, #2430).

- Implement generic mechanism for `layout_()` modifiers, allowing
  layout algorithms to be composed and adjusted uniformly (#1473,
  #2435).

- Change graph constructors to use explicit named arguments instead of
  positional ones (#2466, #2467).

- Improve formatting of error messages originating from the C library
  (#2202, #2515).

- Functions that accept a single vertex now check that exactly one
  vertex is passed (#2556).

## Bug fixes

- Error call in `with_vertex_()`/`with_edge_()` should report the
  public `make_()` function, not the internal helper (#2609).

- Not all loops are plotted when a graph has multiple loops at the
  same vertex (#2594, #2595).

- Fix `hrg_game_impl()` which produced incorrect results (#2577,
  #2578).

- `graphlet_proj()` no longer erroneously assigns class `"igraphHRG"`
  to the returned graph.

- Support character labels in `assortativity_nominal()` in addition to
  integer type codes (#1283, #2432).

- Fix uninitialized variable warnings when building with R 4.5 on
  Windows (#2526, #2527).

- `modularity()` now uses the `"weights"` edge attribute automatically
  when no `weights` argument is supplied.

- Fix `alpha_centrality()` crash when `weights` is set to a custom
  edge attribute name rather than a numeric vector (#915, #2403).

- Fix matrix lists for output when returning multiple matrices from C.

## Documentation

- Error messages throughout the package now use the `cli` package for
  consistent, styled output instead of base R `stop()` (#731, #2588).

- The R Consortium is listed as a funder with its ROR ID in the
  package metadata (#2587).

- Fixes to the pkgdown reference index (#2590, #2592).

- Documentation pages for R functions now automatically link to the
  corresponding C library documentation (#2518).

## Testing

- Structured unit tests alongside snapshot tests have been added for
  all autogenerated `_impl` functions in `test-aaa-auto.R`, verifying
  argument passing and return values (#2448, #2449).

## Internal

- The R interface for most C library functions is now autogenerated
  using the py-stimulus framework, covering 108+ functions including
  BFS and DFS callbacks, leading-eigenvector community detection,
  motif callbacks, sparse matrix operations, and graph-list
  constructors. Arguments use snake_case naming throughout for
  consistency (#2152, #2424, #2442, #2461, #2462, #2464, #2465, #2484,
  #2485, #2531, #2532, #2533, #2534, #2540, #2550, #2551, #2552,
  #2553, #2554, #2555).

- Most direct `.Call()` invocations to C library functions have been
  replaced with autogenerated `_impl()` wrapper functions that use
  explicit named arguments, covering all R source files
  (`R/assortativity.R`, `R/bipartite.R`, `R/centrality.R`,
  `R/centralization.R`, `R/cliques.R`, `R/coloring.R`,
  `R/embedding.R`, `R/flow.R`, `R/games.R`, `R/layout.R`, `R/make.R`,
  `R/other.R`, `R/simple.R`, `R/structural-properties.R`,
  `R/topology.R`, `R/trees.R`, `R/triangles.R`, and others) (#2332,
  #2334, #2345, #2347, #2348, #2351, #2352, #2355, #2357, #2358,
  #2359, #2361, #2362, #2363, #2364, #2365, #2366, #2367, #2368,
  #2369, #2370, #2372, #2373, #2374, #2379, #2380, #2382, #2383,
  #2384, #2386, #2388, #2398, #2422, #2423, #2428, #2429, #2434,
  #2443, #2471, #2476, #2477, #2478, #2539, #2541, #2545, #2546).

See \ 
<https://github.com/igraph/rigraph/blob/05973441b83decdeab8cc9c500a642c00b924770/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.

- 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

- Update vendored C/igraph sources to \ 
igraph/igraph@d2e0f4eb567dfc505227c346a015bef574c4ccd1.

### New functionality

- Support `fit_power_law(implementation = "plfit.p")` to compute the \ 
P-value (#1386).
- Add `max_degree()` (#1403).

`"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).

This major release brings development in line with the C core at \ 
<https://github.com/igraph/igraph>.
See \ 
<https://github.com/igraph/rigraph/blob/1bd2bf79/src/vendor/cigraph/CHANGELOG.md> \ 
for a complete changelog, in particular the section "Breaking \ 
changes".
(A permanent link to the most recent changelog of the C core used in the R package is
<https://github.com/igraph/rigraph/blob/main/src/vendor/cigraph/CHANGELOG.md>.)

Version 1.6.0 of the R package used version 0.9.9 of the C core.
The changes in the 0.10 series of the C core are relevant for version 2.0.0 of \ 
the R package, but not all C core functions are exposed in the R interface.
Changes to the implementation of some functions in the C core may be reflected \ 
in functions in the R package.

The change log below is a summary of the additional changes in the R interface.

## Breaking changes

- `get.edge.ids(multi = TRUE)` and `as_adjacency_matrix(edges = )` are no longer \ 
supported (#1101, #1080).

- Remove `NA` padding for `dfs(unreachable = FALSE)$order` and `$order.out` and \ 
for `bfs(unreachable = FALSE)$order`, also for `igraph_options(return.vs.es = \ 
FALSE)` (#1062, #1124).

- `laplacian_matrix(normalized = TRUE)` uses a different normalization method \ 
(#1102).

- `fit_power_law()` no longer returns a `KS.p` component.

- Remove default value for `loops` argument of `centr_degree_tmax()` (#1114).

- `as_adjacency_matrix()` no longer supports attributes of type `character` (#1072).

- Remove `graph.isomorphic.34()` (#1065, #1067).

- Use `lifecycle::deprecate_soft()` for most deprecated functions (#1024, #1025, \ 
#1104).

- The system libraries GLPK, GMP, and libxml2 are now mandatory for compiling \ 
from source.

## Bug fixes

- Add scalar conversion checks in a few critical places (#1069).

- Check that we receive a scalar when expecting a scalar in C code (#1051).

- Check that matrix sizes are in the supported range before passing them to R \ 
(#1066).

- `transitivity()` now produces a named vector in the local (weighted) case (#1057).

- `plot()` correctly computes intersections between edges and rectangle vertices \ 
(#1021).

- Fix compilation on Windows with spaces in the Rtools path (#1000).

## Features

- Use 30 bits of R's RNG (#1079).

- Breaking change: Remove `NA` padding for `dfs(unreachable = FALSE)$order` and \ 
`$order.out` and for `bfs(unreachable = FALSE)$order`, also for \ 
`igraph_options(return.vs.es = FALSE)` (#1062, #1124).

- New `k_shortest_paths()` to compute the first k shortest paths between two \ 
vertices (#1028).

## Documentation

- Add GitHub bug report form.

- New `vignette("deprecated-dot-case")` that lists deprecated \ 
functions and their alternatives (#1013).

- Move deprecation badge to top of doc pages.

- Remove usage of `get.adjacency()` from intro vignettes (#1084).

- Fix math formatting in `fit_power_law()` docs.

- Fix incorrect usage in `subgraph.edges()` example.

- Clarify that Infomap considers edge directions.

- Improve edge connectivity docs (#1119).

- Add some missing diacritics.

## Internal

- Use `[]` assignment for converting matrices (#1035).

- Move towards autogenerating all bindings (#1043).

- Use %\|\|% from rlang (#1112).

- Replace loop by `lapply()` when returning vertex and edge sets (#1033).

- Do not duplicate prototypes, use a common header for `rinterface.c` and \ 
`rinterface_extra.c` (#1055).

- Clean up some auto-generation code (#1031), remove unused parts from code \ 
generation (#1032), eliminate the use of some deprecated C functions.

- Use integers for mode enum in `cluster_label_prop()`.

- Standardize the handling of some stimulus enum types (#1064).

- Remove unused vectorlist / matrixlist destructors (#1070).

- Remove unused stimulus type VERTEXSETLIST_INT (#1049).

- Remove unused types (#1060).

- Fix Stimulus definitions (#997).

- Avoid deprecated `R_igraph_automorphisms()` (#999).

- Use new ARPACK_DEFAULTS symbol from C core for default arpack options.
