Firefly III
Firefly III ships seven develop builds in six days, still with no changelog attached.
A side-by-side editorial comparison of Stigg and Stripe — release velocity, themes, recent moves, and the top alternatives to consider.
Stigg adds credit reservation and settlement for AI operations days after its agent SDK.
Stigg can now reserve credits before an AI operation starts and settle the actual cost when it finishes. It follows the beta Agent Governance SDK, an open-source library built on Stigg's entitlements engine. Earlier October releases added an Airwallex billing backend, credit usage grouped by feature and a Stripe Projects listing.
Stripe's API changelog is deep in billing maintenance — templates, tax IDs and webhook coverage.
This window is entirely API surface work, weighted toward Invoicing and Billing. Bulk line-item operations, a new Invoice Rendering Template resource, due and overdue webhooks, tax IDs for two more jurisdictions, and filtering for Financial Connections.

Earlier October releases added an Airwallex billing backend, credit usage grouped by feature and a Stripe Projects listing.
Credits have become Stigg's main pricing unit, and the product is adapting them to AI workloads whose cost isn't known up front. Reserve and settle, together with the governance SDK, turns the entitlements engine into a spending control for agents.
Expect the governance SDK to use reservations directly for agent limits, and more reporting on reserved versus settled usage.
This window is entirely API surface work, weighted toward Invoicing and Billing. Bulk line-item operations, a new Invoice Rendering Template resource, due and overdue webhooks, tax IDs for two more jurisdictions, and filtering for Financial Connections.
The direction is completeness rather than new ground: closing gaps that force integrators into workarounds, and extending coverage jurisdiction by jurisdiction. Invoice Rendering Templates is the one item that adds a genuinely new object to the model rather than an option on an existing one.
Expect Invoice Rendering Templates to accumulate the surrounding API surface — more template management and versioning endpoints — and tax ID coverage to keep expanding country by country.
