F-String highlight problem

[brdsio]

Hi,
I started using F-String and I realized that the notebook could not highlight correctly the line.
Here some examples:

With raw string formatting:

Server Information:

You are using Jupyter notebook.

The version of the notebook server is 4.3.1 and is running on:

Python 3.6.0 |Anaconda 4.3.0 (64-bit)| (default, Dec 23 2016, 12:22:00) 
[GCC 4.4.7 20120313 (Red Hat 4.4.7-1)]

My Firefox version: 50.0
I have tested with Google Chrome 57 and had the same behavior.

If you give the path, I would be happy fixing this.
Thank you.

Hi @flaviodrt! This issue was fixed by #2066, so simply upgrade the notebook to 4.4.1 (pip install notebook --upgrade).

Please confirm that this resolves it for you 👌

You can now upgrade to 5.0 👍

Hi @gnestor, thank you for your attention!
I'm sorry about that, I've searched for an issue about f-string but apparently I've failed in my search.
I've downloaded a fresh anaconda install from anaconda's website about one month ago and I thought that it was up to date.

Updating my notebook solved this problem!
Thank you again!
