What is Payhawk?
Payhawk builds out travel management on top of its spend platform
Payhawk's releases show two pushes. First, Payhawk Travel is maturing into a full T&E offering, admin booking on behalf of employees, travel allowances in policy, baggage selection and smart bundles, and in-app trip changes. Second, its EMI banking infrastructure keeps widening: GBP accounts for EU customers, CHF and more holdable currencies, German open-banking top-ups, end-to-end bulk payments, and a new layered payment-fraud-prevention system.
What is Kill Bill?
Kill Bill cuts a new 0.25 line after a long 0.24.x reliability run
Kill Bill, the open-source subscription-billing platform, ships on a slow, deliberate cadence. The just-tagged 0.25.0 opens a new minor line, but its feed entry carries only the maven-release-plugin boilerplate, so the substantive changelog isn't visible in the source. The preceding 0.24.x series was steady reliability work: invoice failure handling (retries, account parking, uniform logging), multi-tenant query indices, and operability improvements like config-source visibility.

◆ Current state
Payhawk's releases show two pushes. First, Payhawk Travel is maturing into a full T&E offering, admin booking on behalf of employees, travel allowances in policy, baggage selection and smart bundles, and in-app trip changes. Second, its EMI banking infrastructure keeps widening: GBP accounts for EU customers, CHF and more holdable currencies, German open-banking top-ups, end-to-end bulk payments, and a new layered payment-fraud-prevention system.
◆ Where it's heading
Payhawk is converging spend management, multi-currency banking, and travel into one finance platform, owning more of where corporate money moves and how it is controlled. The fraud-prevention and master-data-sync work signals enterprise-grade hardening to support that breadth.
◆ Prediction
Expect Travel to keep expanding toward parity with dedicated TMCs and more currency and market coverage on the EMI rails.

Kill Bill cuts a new 0.25 line after a long 0.24.x reliability run
◆ Current state
Kill Bill, the open-source subscription-billing platform, ships on a slow, deliberate cadence. The just-tagged 0.25.0 opens a new minor line, but its feed entry carries only the maven-release-plugin boilerplate, so the substantive changelog isn't visible in the source. The preceding 0.24.x series was steady reliability work: invoice failure handling (retries, account parking, uniform logging), multi-tenant query indices, and operability improvements like config-source visibility.
◆ Where it's heading
The recent arc is hardening the billing core — making invoice runs fail safely, speeding multi-tenant queries, and giving operators more control over configuration and retries. The 0.25.0 cut suggests accumulated work is being promoted to a new line, though the in-feed notes don't yet detail it.
◆ Prediction
Expect 0.25.x to continue the invoice-resilience and operability focus, with detailed release notes following the tag; the next feed entries are likely 0.25.x bug-fix points.
