Hi Everybody! Today we released version 2.9.0 of Operator Toolbox!

The updates here are really driven by you, the community. Namely:

A new operator Read Yahoo Finance to read historic asset prices. That's a common request we heard here, specifically by my friend @kypexin !

An update on Extract Sentiment, which adds French and German dictionaries. A few people including @EL75 asked for it.

An Update to Extract Topics (LDA)Campello in her studies.


Smaller things:
  •  Changed the default tokenization regex in Extract Sentiment from \W to [\s-!"#$%&'()*+,./:;<=>?@[\]_`{|}~]. Now words like 'großartig' are handled correctly.
  • Fixed a bug which makes Read SFTP to ignore proxies.
  • Added a 'show optimization settings' setting to LDA to make it easier to use.

So thanks again for all your feedback! I hope you enjoy the new features.
