Firefly III vs Kill Bill
A side-by-side editorial comparison of Firefly III and Kill Bill — release velocity, themes, recent moves, and the top alternatives to consider.
Firefly III vs Kill Bill: at a glance
What is Firefly III?
Firefly III ships four develop builds in one day, still with no changelog attached.
Every recent Firefly III release is an automated develop pre-release with identical boilerplate and no changelog. October 9 alone produced four builds, the last two about an hour apart in the afternoon, after three each on October 7 and 8. They target testers who pull the develop Docker tag.
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 ships four develop builds in one day, still with no changelog attached.
◆ Current state
Every recent Firefly III release is an automated develop pre-release with identical boilerplate and no changelog. October 9 alone produced four builds, the last two about an hour apart in the afternoon, after three each on October 7 and 8. They target testers who pull the develop Docker tag.
◆ Where it's heading
The build cadence is rising, which points to active work on the develop branch, but the feed says nothing about which features or fixes are moving. Direction will only become visible when a tagged stable release ships with a populated changelog.
◆ Prediction
The entries do not support a feature-level prediction; the next informative event is a stable release that rolls these develop builds up.
Kill Bill
5.0FINANCE
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.
