+## Pre-release v0.4.0.rc4
+
+Happy new year! We're celebrating with another pre-release, with features that should help theme users better adapt to changes moving forward. **We aim to re-release this as `v0.4.0`, with only few changes**.
+
+Notable new additions include:
+
+- modular site components, which split up the site into smaller reusable components; advanced theme users can then remix layouts quickly without duplication
+- a "copy code" button to code blocks
+- fixing bugs in generated TOCs and navigation from previous prereleases
+- various cleanups of CSS and HTML markup
+
+The roadmap to `v0.4.0` is small. We are only looking to:
+
+- finish a migration guide, so users can easily upgrade from `v0.3.3` to `v0.4.0`
+- fix one last bug relating to callouts and custom colors
+- fix any new bugs introduced by this pre-release
+
+Have any questions, thoughts, or concerns? We'd love to hear from you! Please [open an issue](https://github.com/just-the-docs/just-the-docs/issues) or [start a discussion](https://github.com/just-the-docs/just-the-docs/discussions) and let us know!
+
+### Trying out pre-release `v0.4.0.rc4`
+
+Simlar to the prior release, `v0.4.0.rc4` is a **release candidate** for the theme (i.e., a pre-release) with release `v0.4.0` coming soon. We want your help in testing the changes! As of now, the gem on RubyGems and the repository are updated to `v0.4.0.rc4`.
+
+To use this RC explicitly as a remote theme:
+
+```yml
+remote_theme: just-the-docs/[e-mail]4
+```
+
+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.rc4"
+```
+
+By default, **users will not be upgraded to `0.4.0.rc4`**. 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
+```

 ## Pre-release v0.4.0.rc3
 
 Hi there! This is (actually) hopefully the last prerelease before `v0.4.0`; in particular, if we find that this prerelease is stable, we'll re-release it as `v0.4.0`.
 
 In general, this is a more mature pre-release; there are few new features. However, we'll highlight [@pdmosses]'s work in [#992] to better optimize nav generation for large sites (ex 100+ pages). We don't expect this to affect most users; however, **it is technically a breaking change**, and we suggest testing your site before upgrading to this prerelease.
