Hi, when I look at the repo I can see that there are releases for the two versions 3.x.x or 4.x.x?
Which one should I use? 4.2.3 or 3.2.3?
I think ultimately depends on the features you want to use. Maybe figure that out first? Maybe there are features that you want to use in 4.x.x? If not, the typical industry standard is latest - 1. Which would be the 3.x.x
Where I can find in the doc a list of features for each version?
What’s the difference between the 3.x.x and 4.x.x?
Hi @javiertc you can checkout the release notes for the Tyk versions they will include all the new features 
ok, thanks
I’m asking because I added this on 3.2.2
"enable_redis_rolling_limiter": true
But the log is telling me that is deprecated so I don’t know if it’s taking effect or not and I can’t find anything on the doc.
Hi @javiertc ahhh I see, you want to use the enable_non_transactional_rate_limiter instead.

As for documentation I will make a note for our docs team to figure this out.
