InvoiceShelf vs Kill Bill: at a glance
What is InvoiceShelf?
InvoiceShelf 3.0 alphas add bills and suppliers, moving it from invoicing into payables.
Five InvoiceShelf 3.0 alphas shipped in five days. alpha.11 added purchasing (suppliers, bills, supplier credits, payments and refunds) and patched two unauthenticated PHP remote code execution flaws in the Docker image. Later alphas added module API 1.4 with bundled dependencies, EN 16931 e-invoicing with ZUGFeRD / Factur-X hybrid PDFs, a notification bell with automatic payment reminders, and an iOS app headed for TestFlight.
What is Kill Bill?
Kill Bill's 0.25 line ships tags with no notes while 0.24 does the actual work
Kill Bill is publishing two lines that behave nothing alike. The 0.25 releases — 0.25.1 through 0.25.4 across July and August — carry a single line of body text apiece, the maven-release-plugin's tag-copy message, with no changelog at all. The 0.24 line carries structured notes with issue references, and it is where the recent user-facing work sits: shared tenant branding for HTML invoices in 0.24.20, then a revert of part of it in 0.24.21 five days later.

InvoiceShelf 3.0 alphas add bills and suppliers, moving it from invoicing into payables.
◆ Current state
Five InvoiceShelf 3.0 alphas shipped in five days. alpha.11 added purchasing (suppliers, bills, supplier credits, payments and refunds) and patched two unauthenticated PHP remote code execution flaws in the Docker image. Later alphas added module API 1.4 with bundled dependencies, EN 16931 e-invoicing with ZUGFeRD / Factur-X hybrid PDFs, a notification bell with automatic payment reminders, and an iOS app headed for TestFlight.
◆ Where it's heading
3.0 is turning InvoiceShelf from an invoice generator into a small-business accounting app: payables next to receivables, EU-compliant e-invoices, a module ecosystem, and native mobile apps. The pace suggests the team is finishing features before a beta rather than stabilizing.
◆ Prediction
Expect more alphas filling in accounting pieces and modules built on API 1.4/1.5, with the iOS app appearing on TestFlight; the entries don't show a beta date.

Kill Bill's 0.25 line ships tags with no notes while 0.24 does the actual work
◆ Current state
Kill Bill is publishing two lines that behave nothing alike. The 0.25 releases — 0.25.1 through 0.25.4 across July and August — carry a single line of body text apiece, the maven-release-plugin's tag-copy message, with no changelog at all. The 0.24 line carries structured notes with issue references, and it is where the recent user-facing work sits: shared tenant branding for HTML invoices in 0.24.20, then a revert of part of it in 0.24.21 five days later.
◆ Where it's heading
Reading the 0.24 line alone, the theme is invoice-generation robustness continuing from 0.24.18's error handling, retries and account parking, into 0.24.20's branding refactor. The August 12 revert of the template branding key suggests that refactor is not settled. What the 0.25 line contains is genuinely unknown from this feed — the tags exist, the notes do not.
◆ Prediction
Expect the tenant-branding work to return in a corrected form on the 0.24 line, since the revert removed the key rather than the surrounding refactor. Whether 0.25 is a development line or a release line is not something these entries answer.
