Is there a changelog that lists all of the changes?
Hy, Colapsable Menu was really needed,
( as a clear cache button IN home )
Nice the LLMS.tx, let’s see what engines do really read it.
I wish cs-cart would rebuild product grid view block functionality.
Currently in cs-cart displays Most Popular block as 6 columns x 2 rows in desktop and 2 columns and 6 rows in mobile, while most modern websites would display 2 columns and 1 row in mobile with automatic scroller / slide function. I know scroller block is available but that is not the case.
Another release that includes a NEW essential function: the AI large language models SEO llms.txt file.
I’m not able to use this NEW function though because CS-Cart’s business policy dictates that owners of Store Builder Plus don’t need AI SEO functions.
Last update included the NEW function of Videos included in the images and CS-Cart’s business policy dictated that owners of Store Builder Plus don’t need that either.
It’s disappointing. I’ve run CS-Cart for 16 years. I don’t need an Ultimate license - I don’t use multiple warehouses, and I don’t need more than one storefront. Those were the features in Ultimate that warranted the higher price for the Ultimate license.
It’s not right that Plus license holders should be shut out of the new features, just because we only run one storefront.
And it’s not right that Plus license holders should be forced to spend $3000 to upgrade their license to an unnecessary Ultimate license JUST TO GET NEW FEATURES THAT ALL CS-CART STORES SHOULD RECEIVE.
For the first time in 16 years, I’m looking at other ecommerce platforms.
And CS-Cart should update their product comparisons to include these new omissions from the Plus license. The current comparison shows SEO Tools as being equivalent between all licenses and makes no mention of large language models support being excluded from Plus, or the new Video Feature being excluded from the Plus license.
Hello!
The ability to manage llms.txt from the admin panel has been added to the Ultimate edition only, precisely because it can have several storefronts. The ability to manage these separately is therefore essential. The other editions cannot have several storefronts, so they can manage this file directly on the server, just like any other file: .htaccess, robots.txt, domain validation, and any other files required for site ownership validation by other services, etc.
So I really don’t understand why you are so upset about this. You can create the llms.txt file yourself and fill it with the necessary rules.
I’ve been with this ecosystem since the X-Cart days, and later CS-Cart. For years, I wanted to build pochampally.com on your system — that was the plan.
Instead, I ended up having to build much of it myself.
Today, my catalog workflow is simple and live: a product photo or video, and it can go straight online, ready to sell and do business. That is the kind of practical speed and simplicity businesses need.
So when users are told, “You can create the llms.txt file yourself and fill it with the necessary rules,” it feels less like support and more like one more task pushed back onto customers. After all these years, what many of us need is not another assignment — it is real guidance, better tooling, and practical help to actually build our businesses.
I stayed because I believed in the platform. But honestly, I wanted pochampally.com to be built through your system, not outside it.
I got curious after seeing you mention your site so many times, so I actually checked it out.
But now I’m confused — the store itself doesn’t even appear to be running on CS-Cart anymore. So it’s a bit strange to criticize the platform this heavily while showcasing a project built outside of it.
Constructive criticism is absolutely fine, but repeatedly posting exaggerated claims that don’t really match the actual situation starts looking less like feedback and more like forum trolling.
You’ve been around long enough to know where that usually leads 
That site IS actually running CS-Cart. Look at this URL for example:
https://www.stunster.com/index.php?dispatch=products.bestsellers
I think that URL formulation is pretty unique to CS-Cart.
However, the original post was about a different domain to the one you are referring to. The one you are referring to is definitely CS-Cart.
Ah OK. Thanks for the correction.
