What is Invoice Ninja?
Invoice Ninja adds OIDC auto-login while rebuilding its Stripe plumbing
Invoice Ninja ships v5.13 patch releases every few days. October's substance is payments and auth: Stripe moved to the 2025.basil API as a minimum with webhook upgrades, offline payment sync was finished, GoCardless, Razorpay and Braintree got fixes or upgrades, and OIDC gained auto-login and labelling. Several API fixes were found while building new mobile apps.
What is Shift4?
Shift4 Venue Q4-R2 is on canary venues now, with global release set for November 17.
Shift4 publishes release notes for its venue POS suite, Customer Hub and Gift Card & Loyalty products on predictable schedules. Venue Q4-R2 reached canary venues on 12 November with global release planned for 17 November, covering Quick Service POS, Menu Manager, the Status App and access tooling. Q4-R1 went global on 28 October, and Customer Hub 2026w45 headlined a Transactions Marketplace without describing it.

Invoice Ninja adds OIDC auto-login while rebuilding its Stripe plumbing
◆ Current state
Invoice Ninja ships v5.13 patch releases every few days. October's substance is payments and auth: Stripe moved to the 2025.basil API as a minimum with webhook upgrades, offline payment sync was finished, GoCardless, Razorpay and Braintree got fixes or upgrades, and OIDC gained auto-login and labelling. Several API fixes were found while building new mobile apps.
◆ Where it's heading
The work points at two things: keeping the payment gateway layer current with providers' API versions, and preparing the backend for new client apps. European e-invoicing (ZUGFeRD/CII, EPC QR codes) also keeps getting attention.
◆ Prediction
Expect more API fixes tied to the new apps and further gateway updates; whether the apps themselves appear in this feed is unclear.

Shift4 Venue Q4-R2 is on canary venues now, with global release set for November 17.
◆ Current state
Shift4 publishes release notes for its venue POS suite, Customer Hub and Gift Card & Loyalty products on predictable schedules. Venue Q4-R2 reached canary venues on 12 November with global release planned for 17 November, covering Quick Service POS, Menu Manager, the Status App and access tooling. Q4-R1 went global on 28 October, and Customer Hub 2026w45 headlined a Transactions Marketplace without describing it.
◆ Where it's heading
The venue suite moves in quarterly bundles split into two or three releases, each going canary first and global about a week later, with patch releases trailing. Customer Hub ships weekly and has been building enterprise-level menu controls for multi-location groups.
◆ Prediction
Expect the Q4-R2 global notes around 17 November and a Q4-R2 patch shortly after, following the Q3-R3 pattern. What the Transactions Marketplace does remains unclear from the feed.
