Firefly III
Firefly III ships multiple dev builds daily as a stable release approaches.
A side-by-side editorial comparison of Checkout.com and DocuSign — release velocity, themes, recent moves, and the top alternatives to consider.
The public trail is documentation, not releases — scope is visible, pace is not.
Everything reaching us from Checkout.com is documentation surface rather than a changelog: support hubs, developer-resource indexes, authentication guides. What those pages do reveal is the shape of the platform — card acquiring sits alongside a Checkout Business Account for holding and moving funds, a card-issuing program, fraud detection, and identity verification. Several of the newer surfaces carry a Beta label, including EventBridge event delivery, fund spending, and the Identities suite.
DocuSign rebuilt eSignature with AI and is now targeting the full contract lifecycle.
DocuSign has fully reoriented around its Intelligent Agreement Management (IAM) platform, with a proprietary AI engine called Iris now powering both the signing experience and the contract review workflow. The January 2026 eSignature redesign was the most visible signal: AI automates document prep, assists signers in real time, and reduces manual steps at the moment of execution. The March 2026 AI-Assisted Review extension takes Iris further upstream into negotiation and redlining.

The documented surface is widening past payment acceptance into money storage, card issuance, and identity — the standard progression from processor to financial-operations platform. Enterprise plumbing is being documented in parallel: mTLS and AWS PrivateLink for private API connectivity, OAuth 2.0 access keys next to legacy secret keys, per-channel key routing. A published backward-compatibility policy that enumerates exactly which changes are considered safe reads as a platform courting integrations it expects to last years.
The Beta labels on EventBridge, Spend funds, and Identities are the clearest signal available: expect those to move toward general availability before any new category appears. What we cannot see from documentation alone is release cadence — until a changelog surfaces, timing is unknowable.

The March 2026 AI-Assisted Review extension takes Iris further upstream into negotiation and redlining.
The product is moving systematically up the contract lifecycle — from post-signature management (where IAM started) backward through signing and now into pre-signature negotiation. Each step adds another layer of Iris AI to replace human review work. The logical terminus is a fully AI-mediated agreement workflow where Iris handles generation, review, negotiation, and execution with humans in an approval role only.
DocuSign's next likely move is deeper integration between Iris and enterprise data sources (CRM, ERP) so that agreement insights flow directly into existing business systems — or an agentic negotiation mode where Iris proposes and marks up contract terms autonomously.
