Firefly III vs Kill Bill: at a glance
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.
What is Kill Bill?
Kill Bill keeps two release lines alive with small invoice-template changes.
Kill Bill ships on two lines: 0.25.x tags with no published notes, and 0.24.x releases that list small changes. Recent 0.24 work is about invoices: shared tenant branding (logo, company info, colours) in the HTML invoice generator, a revert of a branding template key, and partial-locale support for invoice and catalog translations.
Firefly III vs Kill Bill: editorial side-by-side
Firefly III
5.0FINANCE
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.
Kill Bill
2.5FINANCE
Kill Bill keeps two release lines alive with small invoice-template changes.
◆ Current state
Kill Bill ships on two lines: 0.25.x tags with no published notes, and 0.24.x releases that list small changes. Recent 0.24 work is about invoices: shared tenant branding (logo, company info, colours) in the HTML invoice generator, a revert of a branding template key, and partial-locale support for invoice and catalog translations.
◆ Where it's heading
The visible feature work is per-tenant invoice presentation, with branding and localisation becoming configurable rather than hard-coded. The 0.25 line ships regularly but its notes are bare Maven tags, so its direction can't be read from the entries.
◆ Prediction
More invoice-presentation and localisation changes on 0.24.x are likely; what 0.25.x is building toward isn't visible in the entries.
