As per shown in the figure, I am using the Katalon version of 8.6.8 and I wish to update it to the latest version 9.3.1. However, it prompted me that I am up to date instead of doing to the quick update (https://docs.katalon.com/docs/katalon-studio/get-started/workspace-settings/update-katalon-studio#:~:text=To%20use%20the%20newest%20version,Studio%20is%20up%20to%20date.&text=New%20Update%20will%20be%20prompted,next%20app%20reload%20or%20launch.). May i know how can I update my Katalon?
Hi Tan Yu Xuan, 
I did some digging and found that from Katalon Studio version 9.0.0 onward, the in-app upgrade option was no longer available, and you would have to download the KS 9.x installer file from our website instead …
Here is the download link: Katalon Studio Download Free | Katalon
I will also include the link to the documentation shown above for your reference…
I hope this helps. Let us know if you have any other questions.
Thanks,
Albert
