+## v0.5.0 - 2023-11-03
+
+This release brings support for rendering diagrams server-side
+without the need for the MermaidJS CLI.
+
+You can use this functionality by installing a `mermaidcdp.Compiler`
+into your `mermaid.Extender` or `mermaid.ServerRenderer`.
+For example:
+
+```go
+compiler, err := mermaidcdp.New(&mermaidcdp.Config{
+  JSSource: mermaidJSSource, // contents of mermaid.min.js
+})
+if err != nil {
+  return err
+}
+defer compiler.Close()
+
+md := goldmark.New(
+  goldmark.WithExtensions(
+    // ...
+    &mermaid.Extender{
+      Compiler: compiler,
+    },
+  ),
+  // ...
+)
+```
+
+Use of mermaidcdp is highly recommended for server-side rendering
+if you have lots of diagrams or documents to render.
+This should be substantially faster than invoking the `mmdc` CLI.
+
+### Breaking changes
+- ServerRenderer: Delete `MMDC` and `Theme` fields.
+  If you need these, you can provide them with the `CLICompiler` instead.
+- `CLI` and `MMDC` were flipped.
+  The old `MMDC` interface is now named `CLI`, and it now accepts a context.
+  You can use the new `MMDC` function to build an instance of it.
+- ClientRenderer, Extender: Rename `MermaidJS` to `MermaidURL`.
+- Rename `DefaultMMDC` to `DefaultCLI`.
+- Extender: Replace `MMDC` field with the `CLI` field.
+
+### Added
+- ServerRenderer now supports pluggable `Compiler`s.
+- Add `CLICompiler` to render diagrams by invoking MermaidJS CLI. Plugs into ServerRenderer.
+- Add mermaidcdp subpackage to render diagrams with a long-running Chromium-based process.
+  Plugs into ServerRenderer.
