What is InvoicePlane?

InvoicePlane's 1.7.2 is a mass security remediation, still working through its release candidates.

InvoicePlane is a self-hosted PHP invoicing and quoting application. The 1.7.2 line, now at its second release candidate, is dominated by security remediation: roughly thirty researchers are credited across the beta and RC notes for responsibly disclosed vulnerabilities, with severity, CVSS and GHSA advisories held back until the final release. The RC also warns that installations running custom invoice and quote templates must take manual steps before upgrading.

What is Stigg?

Stigg moves its entitlements and credit checks inside agent orchestrators and gateways.

Stigg now runs inside agent orchestration layers, applying entitlements, credits and budgets to each step of an agent run, and its Agent SDK supports solo.io and agentgateway out of the box. It also lets customers bill subscriptions through Airwallex invoices and payment links. This lands a day after new pricing with a free plan and monthly billing, and three days after Usage Governance went GA.

InvoicePlane vs Stigg: editorial side-by-side

I5.0

InvoicePlane's 1.7.2 is a mass security remediation, still working through its release candidates.

◆ Current state

InvoicePlane is a self-hosted PHP invoicing and quoting application. The 1.7.2 line, now at its second release candidate, is dominated by security remediation: roughly thirty researchers are credited across the beta and RC notes for responsibly disclosed vulnerabilities, with severity, CVSS and GHSA advisories held back until the final release. The RC also warns that installations running custom invoice and quote templates must take manual steps before upgrading.

◆ Where it's heading

The project has spent this cycle absorbing an unusually large volume of external vulnerability reports while simultaneously modernising the platform — PHP 8.2 compatibility arrived on the 1.7.0 branch, and Stripe and PayPal were reintroduced at 1.7.2 beta 1 after having been absent. The decision to withhold advisory details until 1.7.2 goes final is a deliberate disclosure posture, meaning the true scope of what these releases fix is not yet public. Release notes here are dominated by hashes and contributor credits rather than change detail.

◆ Prediction

The final 1.7.2 release and the simultaneous publication of the security advisories are the clear next step, given RC 2 is described as working toward it. Whether further RCs intervene depends on what testing surfaces.

7.5

Stigg moves its entitlements and credit checks inside agent orchestrators and gateways.

◆ Current state

Stigg now runs inside agent orchestration layers, applying entitlements, credits and budgets to each step of an agent run, and its Agent SDK supports solo.io and agentgateway out of the box. It also lets customers bill subscriptions through Airwallex invoices and payment links. This lands a day after new pricing with a free plan and monthly billing, and three days after Usage Governance went GA.

◆ Where it's heading

Stigg is placing its billing engine at the points where AI agents spend money: the orchestrator, the gateway and credit reservation before each operation. Billing-backend breadth, now Airwallex invoicing, keeps pace in the background.

◆ Prediction

Expect more gateway and orchestrator integrations in the Agent SDK and its move out of beta. Billing backends will likely keep widening around Airwallex and its peers.
