What is Drivetrain?

Drivetrain is sharpening its FP&A table workspace with no major directional moves.

Drivetrain's recent cadence is concentrated almost entirely on the table-building experience used by FP&A teams: export fidelity to Excel, conditional formatting, preset actuals columns, and transformation reordering. Most releases are paired duplicates from different feed sources rather than separate launches. There has been no public release activity since mid-September 2025.

What is Firefly III?

Firefly III keeps tagging develop builds daily, still with no release notes.

Firefly III's feed remains automated develop pre-releases. November 12 and 13 added two more develop tags and another boilerplate development release, on top of four on November 12 alone. None includes a changelog.

0.0

Drivetrain is sharpening its FP&A table workspace with no major directional moves.

◆ Current state

Drivetrain's recent cadence is concentrated almost entirely on the table-building experience used by FP&A teams: export fidelity to Excel, conditional formatting, preset actuals columns, and transformation reordering. Most releases are paired duplicates from different feed sources rather than separate launches. There has been no public release activity since mid-September 2025.

◆ Where it's heading

The product is hardening as a spreadsheet-fluent reporting surface rather than expanding into new domains. Each release reduces friction for analysts who previously had to drop into Excel to finish the job — preserved formatting on export, gradient cells, and ordered transformations all point in that direction. The lull since September raises questions about whether a larger release is being assembled.

◆ Prediction

Expect either a delayed bigger release on planning, scenarios, or AI-assisted modeling, or a return to the same incremental table polish. If silence continues into Q2 2026, that itself is a signal that resourcing has shifted.

F5.0

Firefly III keeps tagging develop builds daily, still with no release notes.

◆ Current state

Firefly III's feed remains automated develop pre-releases. November 12 and 13 added two more develop tags and another boilerplate development release, on top of four on November 12 alone. None includes a changelog.

◆ Where it's heading

The project is in a pre-release stretch where builds ship several times a day without notes. The feed shows activity but not what is changing.

◆ Prediction

The feed does not show what the next stable release will contain; a tagged version with a changelog is the next thing worth watching.
