what is the latest version ?

What is the latest version of zencart version 155 or version 154?

If version155 is latest , from where I can get the link to download it ? asking since home page shows version 154 as latest while in some add ons ,it is mentioned they are compatible with 155 , means they have tested in 155 before uploading ?

From where can I get zencart 155 to download?

Thanks in advance

As of today, January 12, 2016, the current version of Zen Cart is v154 ...

We have a Beta version of Zen Cart v155 that we are testing and preparing for release in the next week or two that you can test, the Support thread is at:

Zen Cart v155 should NOT be used on a live site until it is released ...

NOTE: The current version of Zen Cart is always displayed on the home page:

Thanks for the info
