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.
What is Shift4?
Shift4 starts its Q4 venue rollout in canary while Customer Hub adds enterprise modifiers.
Shift4 publishes release notes for its venue POS suite, Customer Hub and Gift Card & Loyalty products on predictable schedules. Venue Q4-R1 reached canary venues on October 20, with global release planned for October 27. Customer Hub 2026w43 lets operators promote modifiers to the Enterprise level.
Kill Bill vs Shift4: editorial side-by-side
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.
Shift4
5.0FINANCE
Shift4 starts its Q4 venue rollout in canary while Customer Hub adds enterprise modifiers.
◆ Current state
Shift4 publishes release notes for its venue POS suite, Customer Hub and Gift Card & Loyalty products on predictable schedules. Venue Q4-R1 reached canary venues on October 20, with global release planned for October 27. Customer Hub 2026w43 lets operators promote modifiers to the Enterprise level.
◆ Where it's heading
The cadence is steady and staged: quarterly venue bundles go canary, then global, then get patches, while Customer Hub ships weekly. Recent Customer Hub builds lean toward multi-location and enterprise management, including Payment Links for Opera and now enterprise-level modifiers. The feed truncates most details, which limits how far this can be read.
◆ Prediction
Q4-R1 should go global around October 27, followed by a patch about a week later as in Q3. The specific features are not visible in the truncated notes.
