+Alters CSS Module detection to instead rely upon file names, rather than directory names.
+
+Treating all CSS files found within `routes/` and `components/` as CSS Modules was not obvious, nor did it offer an easy way to opt out (or in) without editing the Webpack config itself.
+
+This change makes is so that users can opt into CSS Modules from anywhere in their app by instead naming their CSS files according to the pattern `*.module.css`.
+
+Anyone using CSS Modules within `routes/` or `components/` will need to alter their CSS files to be `x.module.css`. If you've disabled CSS Modules in your `preact.config.js`, you can remove that bit of configuration and use file names to instead determine behavior.

+Reduces the `env` parameter of `preact.config.js` to only contain 3 values: `isProd`, `isWatch`, and `isServer`.
+
+Previously, `env` contained many semi-duplicated values (`production` and `isProd`, etc) as well as values that were unlikely to be of much use to many users (what flags were set, for instance). Because of this, the signal-to-noise ratio was rather low which we didn't like. As such, we reduced `env` down to the most basic environment info: what type of build is `preact-cli` doing and for which environement?
+
+If you customize your Webpack config using a `preact.config.js`, please be aware that you may need to update which values you consume from `env`.

+
+To increase transparency and user control over the `template.html`, `<% preact.headEnd %>` and `<% preact.bodyEnd %>` will no longer be supported; instead, users should directly adopt the EJS and keep it in their templates.
+
+In the past, these were abstracted away as they were a bit unwieldy; EJS might be unfamiliar with users and the way data was retrieved from `html-webpack-plugin` was somewhat less than elegant. However, this has much improved over the years and the abstraction only makes simple edits less than obvious, so it is no longer fulfilling it's purpose.
+
+New projects will have a `template.ejs` created in place of the old `template.html`, containing the full EJS template. For existing projects, you can copy [the default `template.ejs`](https://github.com/preactjs/preact-cli/blob/master/packages/cli/src/resources/template.ejs) into your project or adapt it as you wish.
