Firefly III
Firefly III keeps tagging develop builds daily, still with no release notes.
A side-by-side editorial comparison of Adapty and Stripe — release velocity, themes, recent moves, and the top alternatives to consider.
Adapty lets one paywall flow personalise itself with the app's own user data
Adapty has finished moving customers onto one builder: the old Paywall and Onboarding Builders were deprecated on October 1 and Paywalls now live inside Flows & Paywalls. Since then it added a yearly plan sold as 12 monthly payments on native iOS, and the November 9 roundup brings custom tags, where the app passes a value through the SDK and any text in a flow can display it, alongside flow funnels and screen animations.
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.

With the migration done, the work has moved to making each flow do more: personalised copy, funnel analytics on flows, and animation. Adapty is turning the paywall builder into a general onboarding and conversion surface, with agent-built flows from August and pricing experiments like the 12-payment yearly plan layered on top.
Expect more SDK-fed personalisation and per-screen analytics inside flows, and the 12-payment yearly plan to extend beyond native iOS; the entries give no timeline for either.

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.
