+# Version 0.4.0
+
+We've released version 0.4.0 of [Textual](https://pypi.org/search/?q=textual).
+
+As this is the first post tagged with `release` let me first explain where the blog fits in with releases. We plan on doing a post for every note-worthy release. Which likely means all but the most trivial updates (typos just aren't that interesting). Blog posts will be supplementary to release notes which you will find on the [Textual repository](https://github.com/Textualize/textual).
+
+Blog posts will give a little more background for the highlights in a release, and a rationale for changes and new additions. We embrace *building in public*, which means that we would like you to be as up-to-date with new developments as if you were sitting in our office. It's a small office, and you might not be a fan of the Scottish weather (it's [dreich](https://www.bbc.co.uk/news/uk-scotland-50476008)), but you can be here virtually.
+
+<!-- more -->
+
+Release 0.4.0 follows 0.3.0, released on October 31st. Here are the highlights of the update.
+
+## Updated Mount Method
+
+The [mount](/api/widget/#textual.widget.Widget.mount) method has seen some work. We've dropped the ability to assign an `id` via keyword attributes, which wasn't terribly useful. Now, an `id` must be assigned via the constructor. 
+
+The mount method has also grown `before` and `after` parameters which tell Textual where to add a new Widget (the default was to add it to the end). Here are a few examples:
+
+```python
+
+# Mount at the start
+self.mount(Button(id="Buy Coffee"), before=0)
+
+# Mount after a selector
+self.mount(Static("Password is incorrect"), after="Dialog Input.-error")
+
+tweet = self.query_one("Tweet")
+self.mount(Static("Consider switching to Mastodon"), after=tweet)
+
+```
+
+Textual needs much of the same kind of operations as the [JS API](https://developer.mozilla.org/en-US/docs/Web/API/Node/appendChild) exposed by the browser. But we are determined to make this way more intuitive. The new mount method is a step towards that. 
+
+## Faster Updates
+
+Textual now writes to stdout in a thread. The upshot of this is that Textual can work on the next update before the terminal has displayed the previous frame.
+
+This means smoother updates all round! You may notice this when scrolling and animating, but even if you don't you will have more CPU cycles to play with.

+</div>
+
+
+## Multiple CSS Paths
+
+Up to version 0.3.0, Textual would only read a single CSS file set in the `CSS_PATH` class variable. You can now supply a list of paths if you have more than one CSS file.
+
+This change was prompted by [tuilwindcss](https://github.com/koaning/tuilwindcss/) which brings a TailwindCSS like approach to building Textual Widgets. Also checkout [calmcode.io](https://calmcode.io/) by the same author, which is an amazing resource.
