You can learn more about the technical details of this release’s changes in our Release Notes.

Updating to WHMCS 9.0

To take advantage of these changes, you need to update to WHMCS 9.0.

Right now, WHMCS 9.0 is a Release Candidate (RC). We only recommend RC releases for feedback, testing, and development purposes. This gives you plenty of time to make sure your customizations are up-to-date for the new version and check the compatibility of any third-party modules you use.

Nexus Cart Experience

We have added a new shopping cart with improved UI for your clients. The new Nexus cart is dynamic, so clients can see changes without refreshing the page. This makes it easier for your clients to view new items in their cart, add promo codes, and recalculate taxes without leaving the page.

AI Domain Namespinning

WHMCS Namespinning now includes AI-powered domain name suggestions. When clients purchase a domain, they can use a keyword or description to search for the best domain name. Clients can also still search for an exact domain name.

CSV Support for ImportAssist

We have added support for CSV files with ImportAssist. You can use CSV files to simplify how you import customer data into WHMCS.

Credit and Debit Notes

We have introduced credit and debit notes to our invoicing system. This feature can help you with invoice management and tax compliance by making sure all invoices list transactions consistently.

The system automatically creates credit and debit notes when you add a credit to an invoice or issue a refund. The system adds each credit or debit note to its associated invoice.

New Ledger

The Transactions section of an invoice is now called the Ledger. The Ledger is where you will see all the transactions associated with an invoice, including credit and debit notes.

Updating to WHMCS 9.0

To take advantage of these changes, you need to update to WHMCS 9.0. We recommend making sure your customizations are up-to-date for the new version and checking the compatibility of any third-party modules you use.

This version apparently has installation problems. It corrupts the database and puts the system in maintenance with err2, so be very careful using it.
I found it strange that it was released without even needing to access the WHMC panel.

@jcobellobr Unfortunately It’s not a nulled version so You can’t proceed installation without a valid license, and the files are completely untouched, downloaded directly from the WHMCS client area.

First, the installer doesn't run, it gives a 404 error, and even forcing it with another installer it gives an error in the administration

Phiên bản này dường như có vấn đề về cài đặt. Nó làm hỏng cơ sở dữ liệu và đưa hệ thống vào chế độ bảo trì với lỗi err2, vì vậy hãy hết sức cẩn thận khi sử dụng.
Tôi thấy lạ là nó được phát hành mà thậm chí không cần truy cập vào bảng điều khiển WHMC.

Nó sử dụng API để cập nhật
