Start your weekend with the new Node-RED 4.0.9 release!

A handle of useful fixes and a few small feature enhancements. Checkout the changelog for the full list.

- When you select a subflow instance node, the context sidebar will now show you its flow context under the 'node' section. Super useful as this level of context was otherwise inaccessible in the editor. ([#5025](https://github.com/node-red/node-red/pull/5025))
- The context sidebar now remembers what you've expanded when you refresh, so you don't have to find your place again when checking for updated values ([#5021](https://github.com/node-red/node-red/pull/5021))
- The auto-complete for context field names now handles loooong names better ([#5042](https://github.com/node-red/node-red/pull/5042))

At the time of writing, the docker containers are still building - so check back later if you need to use them.

For a moment - I read it as 4.9.0 😲

Always nice to see What's happening!

I have a pi zero running v4.0.8 with nodejs 20 on bookworm, installed using the bash curl script. It has been running with no problems.

I upgraded to 4.0.9 using  
`sudo npm install -g --unsafe-perm node-red`  
and when I restart node-red I just get `Illegal instruction`.

I will re-install 4.0.8 with npm and see if it recovers.

I installed 4.0.8 using npm and it also crashed the same way. Then I ran the install script and it was ok. I assume that the script must do something different.

I have opened a [new thread](https://discourse.nodered.org/t/illegal-instruction-after-npm-install-on-old-pi-zero-but-ok-using-install-script/95487) for this, as it is not related to the new release.

Nice work!

The only thing I found is that the Dashboard 2.0 page list at the right in node-red jumps back to top every time a page or group configuration is changed.

After a long time away from Node Red I see version 4 is out, thanks for the great work!

But it seems to me that the getting started guide

> **[Running on Raspberry Pi : Node-RED](https://nodered.org/docs/getting-started/raspberrypi)**

is not up-to-date with version 4? At least the Node.js versions seems to be different?

Can you be more specific about exactly what you mean?

With regard to nodejs you can specify which version you want when you run the script.
