Firefly III
Firefly III ships automated nightly builds daily with no stable release in the current window
A side-by-side editorial comparison of SolidInvoice and Copperleaf — release velocity, themes, recent moves, and the top alternatives to consider.
SolidInvoice finally shipped the 3.0 it spent a year staging in alphas and betas.
After more than twelve months of alpha and beta releases, SolidInvoice 3.0 landed in June with the accumulated work of that cycle: email verification, Google OAuth, two-factor authentication, real user profiles, flat-rate tax support and a Meilisearch-backed search layer. Underneath it, the project moved onto a shared platform config and pulled trial and SaaS logic into an external bundle. The 2.3 line ran in parallel the whole time, absorbing security backports.
Copperleaf is publishing at high volume on capital planning and regulatory intelligence — content-led motion, no product releases visible.
Copperleaf is an asset investment planning platform serving utilities and rail infrastructure owners. All recent activity is content output: executive briefs, thought-leadership blog posts, and what appears to be a product-feature landing page for a 'Regulatory Intelligence for Capital Planning' module. No software release notes or changelog entries are present in this batch.

Two threads run through this changelog. The visible one is identity and account management catching up to what users expect from a billing app — signup verification, OAuth, 2FA, self-serve company deletion. The less visible one is the codebase being restructured around reusable solidworx platform components with Sentry and Prometheus instrumentation, which is the shape of a project preparing to run itself as a hosted service rather than only as a download.
With 3.0 out and 3.0.1 already repairing the upgrade migration path, the near-term work is likely more 3.0.x stabilization for people coming off 2.3 rather than new features.

No software release notes or changelog entries are present in this batch.
The content strategy is dense and consistent — risk-informed prioritization, regulatory readiness, value-based capital allocation, rail constraint modeling — topics that map directly to the platform's core positioning. The 'Regulatory Intelligence' framing appears to be an emerging product concept aimed at utilities needing to defend capital plans to regulators, a workflow that currently lives in spreadsheets and consultants.
A formal product announcement or case study for the Regulatory Intelligence module is likely the next step, converting this content buildup into a product launch. The parallel rail-focused editorial series suggests a vertical go-to-market push in that sector.
