Recurly vs Kill Bill: at a glance
What is Recurly?
Recurly is shipping payment-gateway maintenance — Vantiv, WorldPay, Adyen, ApplePay tweaks, no headline moves.
The captured window is dominated by narrow gateway-level updates: WorldPay now passes sales tax, Vantiv learned three additional response codes (142, 141, 378, plus reworked handling for 229 and 992), Check Commerce's sandbox endpoint moved, and the V3 client libraries gained payment_gateway_references parameters. Adyen got SEPA retry support and Apple Pay added MPAN tracking for merchant-derived tokens. The published_at dates are 2026 but the entry bodies are dated Jan–Feb 2025 — the changelog feed appears to be republishing year-old gateway notes on a new cadence.
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
The captured window is dominated by narrow gateway-level updates: WorldPay now passes sales tax, Vantiv learned three additional response codes (142, 141, 378, plus reworked handling for 229 and 992), Check Commerce's sandbox endpoint moved, and the V3 client libraries gained payment_gateway_references parameters. Adyen got SEPA retry support and Apple Pay added MPAN tracking for merchant-derived tokens. The published_at dates are 2026 but the entry bodies are dated Jan–Feb 2025 — the changelog feed appears to be republishing year-old gateway notes on a new cadence.
◆ Where it's heading
Recurly is in a maintenance posture for its payment-gateway integrations rather than reaching for new product surfaces. The work is real and matters for billing reliability — adding response codes prevents misclassified declines, SEPA retries recover EU subscription revenue, MPAN tracking improves tokenization reporting — but none of it expands what Recurly is or who buys it. Webhook auto-pause for unresponsive endpoints is the most operationally interesting item, hinting at a small reliability layer Recurly is willing to enforce on its merchants.
◆ Prediction
Without fresher entries it's hard to call where the product is heading. The likeliest next move is more gateway breadth (Stripe response-code parity, additional EU gateways), and possibly a friendlier developer-facing release-notes feed since the current one is republishing year-old content. The team should consider fixing the changelog publishing date drift before commenting deeper on velocity.

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.
