Firefly III vs GOAT.tax: editorial side-by-side

F5.0

Firefly III keeps shipping develop builds with no changelog.

◆ Current state

All ten recent entries are automated develop pre-releases, three of them on October 17 alone, each with the same boilerplate and no changelog. Nothing in them tells users what changed, so no user-facing progress can be read from this feed.

◆ Where it's heading

The project is in a continuous-build phase on the develop branch, with work collecting for a future stable release that isn't shown here. Until a tagged release with notes appears, the feed shows activity, not direction.

◆ Prediction

It's unclear from these entries when the next stable release lands. The next useful signal will be a versioned release with a real changelog.

5.0

GOAT.tax adds Form 6765 Section G reporting for large R&D credit filers.

◆ Current state

GOAT.tax is filling in what Form 6765 requires. The 10/15 release adds a Qualified Activity Type breakdown (direct research, supervision, support) for studies that meet the Section G thresholds, captures EIN and NAICS codes for the report, and extends bulk SME assignment to wage and expense workspaces. Earlier releases added multi-company support, partner white-labeling, a Controlled Group data model and broader state credit coverage.

◆ Where it's heading

The product is moving upmarket: Section G applies only to filers above $1.5M in QREs and $50M in gross receipts, and multi-company plus Controlled Group work targets complex corporate structures. A steady UI redesign of workspaces runs alongside, aimed at making large studies manageable.

◆ Prediction

Expect the Controlled Group model to surface as user-facing computations, and Section G output to flow into the generated 6765 report within the next few releases.
