## v0.16.0

- Update `cmark-gfm` from upstream, including a denial-of-service fix for tables with a large number of autocompleted cells, corrected `end_line` source positions for single-line and multi-line HTML blocks, and a fix for trailing newlines when rendering inline nodes.
- Update `cmark-gfm` from upstream, including two table-rendering protections: avoid repeatedly scanning preceding cells, and limit the number of automatically completed cells to prevent denial of service.
- Correct `end_line` source positions for single-line and multi-line HTML blocks.
- Fix trailing newlines when rendering inline nodes.
- Add support for front matter (`CMARK_OPT_FRONT_MATTER`): a `---` delimited block at the start of a document is captured as a `CMARK_NODE_FRONT_MATTER` node. The raw content is available via `node.string_content` and an optional format hint (e.g. `"yaml"`, `"toml"`) via `node.fence_info`.
- Allow `:` in HTML tag names to support XML namespace prefixes (e.g. `<svg:circle>`, `<xhtml:div>`).
