Docs on textual.textualize.io can be ahead of latest release

[davetapley]

I just got very confused because VSCode couldn't find @on(TextArea.Changed) per here:

I verified I was on v0.38.1, as shown in the header ↗️

Turns out, I presume, those docs are from 3 day old:

• Add TextArea.Changed and TextArea.SelectionChanged messages #3442

but that hasn't actually been released yet 😬

Aye, this is a small unfortunate side-effect of the blog being mixed in with the rest of the docs; so on some rare occasions, where a new blog post needs to be published ahead of a release of Textual, the newer Textual docs can "leak". It's something we'd eventually like to tidy up (I think we have an issue floating around somewhere for this -- could be on the internal board).

The one upside is that it does remind us some folk actually do read the docs! ;-)
