What is Firefly III?
Firefly III ships 2–3 dev builds per day — user-facing changes not yet in release notes
Firefly III is in active daily development, producing multiple pre-release builds each day under the 'develop' branch. The September cadence is high, but the automated GitHub Release entries omit changelog content — the project maintains a separate changelog.md that populates only at stable release time. Nothing in this batch confirms what features are under active construction.
What is Kolleno?
Kolleno ships monthly AR digests, with the Task Manager rebuild as the one real pivot.
Kolleno publishes a monthly roundup rather than per-feature notes, and the bodies are largely a standing intro about control, workflows and high-volume teams — the titles carry the actual news. Across the last several months the substance has been steady accounts-receivable work: dashboards for team performance, payment retry and customer pause logic, AI-read remittance files, AI-detected promises to pay, and now expanded Salesforce sync. The one release that broke the digest pattern was June's Task Manager rebuild, which replaced Collectors Tasks outright.

Firefly III ships 2–3 dev builds per day — user-facing changes not yet in release notes
◆ Current state
Firefly III is in active daily development, producing multiple pre-release builds each day under the 'develop' branch. The September cadence is high, but the automated GitHub Release entries omit changelog content — the project maintains a separate changelog.md that populates only at stable release time. Nothing in this batch confirms what features are under active construction.
◆ Where it's heading
Without changelog detail in the dev builds, direction is unreadable from these entries alone. The sustained high cadence — multiple drops per day — suggests active work, but whether that is bug fixing, feature development, or refactoring cannot be determined until a stable release with a populated changelog lands.
◆ Prediction
A stable release with a populated changelog.md will provide the first meaningful signal. Given the dev cadence, one is likely within days.
Kolleno
2.5FINANCE
Kolleno ships monthly AR digests, with the Task Manager rebuild as the one real pivot.
◆ Current state
Kolleno publishes a monthly roundup rather than per-feature notes, and the bodies are largely a standing intro about control, workflows and high-volume teams — the titles carry the actual news. Across the last several months the substance has been steady accounts-receivable work: dashboards for team performance, payment retry and customer pause logic, AI-read remittance files, AI-detected promises to pay, and now expanded Salesforce sync. The one release that broke the digest pattern was June's Task Manager rebuild, which replaced Collectors Tasks outright.
◆ Where it's heading
The direction is consolidation of the operational surface around collections rather than deeper automation of any single step — query management, reconciliation, reporting and now CRM sync all pulled toward one place. AI shows up repeatedly but as a component inside existing workflows (reading remittances, detecting promises to pay) rather than as a separate product. Recurring emphasis on high-volume teams suggests the buyer is moving upmarket.
◆ Prediction
Expect the Salesforce sync to be followed by comparable depth on other systems of record, since an AR platform consolidating query management needs the customer context to arrive automatically rather than by hand.
