Kill Bill vs InvoicePlane

Three 0.25.x tags landed in the last five weeks, each published as a bare maven-release-plugin tag copy with no release notes at all. The substantive documentation sits on the 0.24 branch, where 0.24.18 reworked invoice failure handling with retries, uniform WARN logging, and account parking on unrecoverable invoice exceptions, and 0.24.19 limited itself to a Shiro update and dropping Joda from the Java client. The newest versions are the least legible ones.

This reads as a maintenance-mode billing core: 0.24 remains the documented, operator-facing branch while 0.25 advances as plumbing nobody writes up. The one behavioral change that genuinely needs operator attention, accounts being parked on any invoice exception by default, arrived on 0.24 rather than the newer line. Nothing across these entries points at new billing capability; the work is error handling, indices, and dependency currency.

Expect 0.25.x point tags to keep arriving without notes, with anything operators must know documented on the 0.24 line instead. What 0.25.0 actually changed is not recoverable from these entries.
