Firefly III ships multiple dev builds daily as a stable release approaches.
Firefly III is in active pre-release development, publishing multiple automated dev builds per day to the `develop` Docker tag. The 10 most recent entries are all development channel releases with no individual changelog content—they represent a staging pipeline for a forthcoming stable version rather than discrete feature drops.
Zoho Billing can take money outside a subscription — and is now deciding who may touch what.
The window splits three ways. Collection expanded first: hosted payment pages for individual items, shareable as a URL, QR code, iframe or HTML button, followed by a redesigned single-page checkout in early access with abandoned-cart recovery and saved progress. Reporting was cut along subscription-planning dimensions — active subscriptions by country and by product, plus a payment-method summary flagging cards near expiry. The newest thread is access control, with role-based permissions arriving on the SKU field in July and on extensions in August.
Firefly III is in active pre-release development, publishing multiple automated dev builds per day to the `develop` Docker tag. The 10 most recent entries are all development channel releases with no individual changelog content—they represent a staging pipeline for a forthcoming stable version rather than discrete feature drops.
The high-cadence dev build frequency (3–4 builds per day) suggests active work on a release branch, but the entry content is boilerplate without specifics. Based on past Firefly III stable releases, this pattern typically precedes a minor or patch stable release. The project continues its self-hosted, open-source positioning with no sign of SaaS or hosted pivot.
A stable release is likely within 1–2 weeks based on the dev build cadence; the actual feature content will only be visible in the stable release changelog.md entry.

Two of these directions matter. Zoho Billing now collects for a single item outside any subscription, records the payment and raises the invoice, which puts it in reach of transactions it previously had no surface for. The access-control work points somewhere else: per-field and per-extension permissions are what a catalog shared by a larger team needs, not what a small biller asks for. Reporting by country, product and card expiry is groundwork for retention and dunning rather than accounting output.
Expect the redesigned checkout and item payment pages to leave early access and reach organizations created after the July cut-off, with role-based access continuing to spread field by field.
