We're running 4.2.2 waiting patiently for 4.3.x due to the several customs modifications and addons on our site. However 4.3.x may be a while so we are considering updating to 4.2.4 in the meantime. First we'd like to know what advantages there are in 4.2.4 such as any speed improvements, etc.?
There is an opinion that every new CS-Cart version is faster than previous. But we do not notice the big differences in a website speed between 4.2.2 and 4.2.4.
You may also check the changelog and learn what is new in 4.2.4. version.
Best regards, Alt-team.

My Pingdom and GTMetrix scores are the same with 4.2.4 as they were with 4.2.2. Not slower, not faster. However, I do think the backend of my site seems more responsive (not that this matters very much, just making an observation).
