What is Firefly III?

Firefly III's feed is a nightly build log — every entry is the same boilerplate with no changelog.

The visible window contains only development releases, several per week and occasionally two in a day, each carrying an identical warning-and-installation body that states outright that the changelog is not included. Some days also emit a bare automated develop tag alongside the full post.

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.

Firefly III vs Recurly: editorial side-by-side

F5.0

Firefly III's feed is a nightly build log — every entry is the same boilerplate with no changelog.

◆ Current state

The visible window contains only development releases, several per week and occasionally two in a day, each carrying an identical warning-and-installation body that states outright that the changelog is not included. Some days also emit a bare automated develop tag alongside the full post.

◆ Where it's heading

This is a public nightly channel, not a release feed, so the entries measure build automation rather than product direction. Stable releases are published elsewhere; nothing in these notes indicates what is being worked on or when the next tagged version lands.

◆ Prediction

Expect the development build stream to continue at the same daily-to-every-other-day rate; the feed will not reveal feature work unless the project starts including changelog content in these posts.

Recurly is shipping payment-gateway maintenance — Vantiv, WorldPay, Adyen, ApplePay tweaks, no headline moves.

◆ 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.
