[C/igraph](https://igraph.org/c/) 0.9.4 is now released. This is likely to be the last release of the 0.9.x series, with development efforts shifting to 0.10.

As usual, the source code can be obtained from [the GitHub releases page](https://github.com/igraph/igraph/releases/tag/0.9.4).

igraph is also included in many package managers and Linux distros. To see if your favourite package manager has the latest version, check [igraph package versions - Repology](https://repology.org/project/igraph/versions)

Additionally, now a Dash docset is available for C/igraph. It can be viewed with documentation browsers such as [Dash](https://kapeli.com/dash), [Zeal](https://zealdocs.org/), [Velocity](https://velocity.silverlakesoftware.com/) or [Emacs Helm-Dash](https://github.com/dash-docs-el/helm-dash). This is provided for convenience. As before, the latest version of the documentation is available [on the website](https://igraph.org/c/#docs), and version-specific documentation is included in the source tarballs.

### Changed

- Unweighted transitivity (i.e. clustering coefficient) calculations now ignore multi-edges and edge directions instead of rejecting multigraphs and directed graphs.
- `igraph_transitivity_barrat()` now returns an error code if the input graph has multiple edges (which is not handled correctly by the implementation yet).

### Fixed

- `igraph_local_scan_k_ecount()` now handles loops correctly.
- `igraph_transitivity_avglocal_undirected()` is no longer slower than `igraph_transitivity_local_undirected()`.
- Worked around an invalid warning issued by Clang 9.0 when compiling with OpenMP.

### Other

- Documentation improvements.
