To use the updated Chrome 55 version, you have to wait until December 6th or if you are more interested to check this updation then you can run pre-release code. You will mainly notice the difference between Chrome 55 and its previous versions. If your computer already has a lot of memory or you close tabs to save some memory, then maybe you can’t see the impact of updation.
The Chromium Team is hoping to release more memory-saving updates in the future, specifically focusing on low-end devices with less than 1 GB of memory.
