+## Pre-release v0.4.0.rc5
+
+Hi everyone, we're so excited to finally release `v0.4.0`! For posterity's sake, we're going to release `v0.4.0.rc5` and then immediately re-release it as `v0.4.0`; this should make it more clear what changes were introduced in the lead up to the minor release.
+
+This RC does not introduce any major user-facing features. It adds more customizability for custom SCSS variables (fixing a bug with callout introduction order), `lunr` indexing, and loading `mermaid` locally. In addition, it fixes bugs introduced in `.rc4`: incorrect CSS, inconsistencies with code block backgrounds in dark theme, and the copy code button. It also adds a migration guide for users coming from `v0.3.3`.
+
+### Trying out pre-release `v0.4.0.rc5`
+
+Simlar to the prior release, `v0.4.0.rc5` is a **release candidate** for the theme (i.e., a pre-release) with release `v0.4.0` following immediately after. While we don't anticipate many users using this RC, it is still possible to opt-in.
+
+To use this RC explicitly as a remote theme:
+
+```yml
+remote_theme: just-the-docs/just-the-docs@v0.4.0.rc5
+```
+
+To use this RC explicitly as a gem-based theme, pin the version in your `Gemfile` and re-run `bundle install` or `bundle update just-the-docs`:
+
+```Ruby
+gem "just-the-docs", "0.4.0.rc5"
+```
+
+By default, **users will not be upgraded to `0.4.0.rc5`**. To enforce that explicitly, either:
+
+1. pin your gem version in your `Gemfile`, like so
+```Ruby
+gem "just-the-docs", "0.3.3"
+```
+2. freeze the `remote_theme`, like so
+```yml
+remote_theme: just-the-docs/just-the-docs@v0.3.3
+```
