Payroll platform's developer changelog has slowed from monthly in 2024 to three releases across all of 2025.
PayFit is a payroll and HR platform with deep France and UK coverage. The developer-facing changelog ran monthly through 2024 but slowed to three releases in 2025 — workingTimeModality and exemption fields on French contract endpoints (December), retroactive 24-month accountingV2 document generation (August), and absence status filtering (June). 2024 entries fill the rest of the recent window.
Purchasely puts its Management API in the terminal and in AI coding agents
Purchasely is an SDK and console for in-app subscriptions and paywalls. Version 6.2 in October let apps send their own business events to trigger campaigns and linked every purchase to the paywall, placement and test that drove it. On November 5 it released a CLI in beta that exposes every Management API operation as a command, shows app metrics in the terminal, and installs a Purchasely plugin into AI coding agents, with dry runs, plan-then-apply and a read-only mode for safe writes.

The public developer changelog has clearly deprioritized. The 2025 entries are field additions and existing-endpoint improvements rather than new product surfaces. PayFit may be making fewer partner-facing changes, or simply moving partner communication off the public changelog.
Without more recent data the safe bet is continued slow cadence on the developer changelog with primarily incremental field additions. A return to monthly cadence would be the early signal that PayFit is reinvesting in the partner ecosystem.

The SDK releases have steadily moved control of paywalls and campaigns out of app code and into the Console. The CLI moves it again, into scripts, CI and coding agents, with guardrails designed for automated writes.
The CLI needs Management API access enabled by Purchasely staff, so the next likely step is broader self-serve access, or more agent-facing tooling built on the same API.
