OpenCart 4.1.0.3 Released: Key Fixes and Improvements

Posted by Adem on March 25, 2025

OpenCart has rolled out version 4.1.0.3, bringing several refinements, bug fixes, and optimisations. This minor release focuses on improving code quality, fixing the upgrade procedure, fixing an issue with the extension installer and refining code comments across the platform. Let’s dive into the key changes and what they mean for developers and store owners.

What’s New in OpenCart 4.1.0.3?

1. Fixed Upgrade Procedure

One of the critical fixes in this release addresses an issue where the version upgrade process was failing (#14703). This patch ensures smoother upgrades for users moving from previous versions, reducing potential downtime during upgrades.

2. Code Comment Improvements

A significant portion of this update involves refining code comments across multiple files, enhancing code readability and developer experience. Contributions from @TheCartpenter include:

Updated documentation for upgrade procedures (#14708).
Improved model comments and corrected package paths in extensions (#14725, #14726).
General tidying of code and removal of deprecated comments (#14714, #14717).

These changes drastically improve developer understanding and speed of work.

3. Admin Extension Installer Error Update

A new contributor, @milsaware, made their first contribution by improving the admin extension installer's error handling (#14709).

4. Removal of Redundant Fields

@farshadfmr removed an unnecessary country_id reference (#14713).
The deleteDescriptionsByLanguageId method in localization models was updated to exclude deprecated country_id and zone_id references (#14720).

These changes help streamline database operations and reduce legacy code clutter.

New Contributors Welcome!

This release also introduces two new contributors:

@milsaware (#14709)
@farshadfmr (#14713)

Their contributions highlight OpenCart’s growing community involvement.

Firstly, thanks ever so much to you and your team for getting these two sites up and running. It’s a pleasure to work with people who are so helpful and responsive to our requirements. We’re very happy with both sites and all seems to be working fine.

Aidan, Nauticalia

After many years of trying to update my website, dealing with problematic code, delays, etc, I found Antropy about 10 years ago. I can not say enough great things about the quality of their coding and stability of my website along with the professionalism of their staff. I now have a well functioning website that has stood the test of time. Our site is an e-commerce site so that having it up and running is crucial to our business. On the rare occasion that there is a problem with the site, Antropy's team is quick and responsive to finding the problem and fixing it quickly.

Lynn Reznick, Off The Mark

Thank you all for the hard work, it has paid off, it looks good. The logo is great to promote the practice and the website we can be proud of. Thank you again.

Biddy Arnott, Group Analytic Practice Ltd

Very impressed with the quick service! There is nothing more we need help with right now but we would certainly use you in the future for other issues or alterations we may have. Thank you very much!

Jemma, Aquafayre

We worked with Antropy on our new webshop at kikgoes.nl in the past months. We have enjoyed working with them because of their extensive knowledge of Opencart and the rapid pace of development. We regularly added requirements to the projects and we've never had anything that couldn't be done. We look forward to working with Antropy again for new projects or adjustments to our webshop!

Joël van Daalen, Kik Cycleparts

Merged two previously HUGE separate sites (website and webstore) into one streamlined website with integrated store, with improved social media and mailing list results. Joe helped communicate complicated jargon into simpler terms, solved issues/queries quickly, and the follow up support has been invaluable.

Jo, Cold Spring Records

Thanks again for all your hard work on the 3D renders … the results have been fantastic and I look forward to working together again in the future.

Marios Pantelli, Sewing Machine Company

Excellent work, delivered in a friendly and consultative way throughout the whole process. For a small company such as my own it was great to be guided through the process, and all my requests were responded to and I felt involved from start to finish.

Phil Saville, Rook Systems

The deliveries are now incredibly clear and there is no more admin work on this side which is excellent. It’s amazing really and I think our customers enjoy knowing exactly when they are getting it unlike nearly every other furniture company out there! Thanks for this.

Jonathan Haskins, Get Laid Beds

Antropy not only gave freely of their time to talk with me, they had the patience to teach me as we went along. They came up with various ideas that allowed me to choose what I liked best and with their guidance we got exactly the website we dreamed about.

David, RC Geeks

Good to work with, very straight forward

Grant Berry, Home World

Taken on both smaller and large projects to a very high standard. Delivered on time, with a professional level of service. Always better than we envisioned.

We are really delighted with the finished product, it has far exceeded our expectations... Many thanks again for your support and setting up what I feel is the best Alzheimer's website in the country.

Lynne, MK Alzheimer's

We recently started using Antropy for our OpenCart website as internal IT is swamped and we needed back up and they have been great. Work is quick and efficient, we never need to ask for something twice and communication is good. Gives us confidence that when we need something to be done, it will be and to a high standard.

Just wanted to say a big thank you for all your help and support thus far. You've been absolutely brilliant. You've given me absolute confidence that when there is a problem it is sorted which really gives me peace of mind.

We found Antropy to be very responsive and approachable to work with. They gladly took our own designs and transformed them into an easy-to-manage website. Communication was easy and any requests for change were promptly done. Many thanks for the work!
