About 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.
