Kill Bill cuts a new 0.25 line after a long 0.24.x reliability run

◆Current state
Kill Bill, the open-source subscription-billing platform, ships on a slow, deliberate cadence. The just-tagged 0.25.0 opens a new minor line, but its feed entry carries only the maven-release-plugin boilerplate, so the substantive changelog isn't visible in the source. The preceding 0.24.x series was steady reliability work: invoice failure handling (retries, account parking, uniform logging), multi-tenant query indices, and operability improvements like config-source visibility.
◆Where it's heading
The recent arc is hardening the billing core — making invoice runs fail safely, speeding multi-tenant queries, and giving operators more control over configuration and retries. The 0.25.0 cut suggests accumulated work is being promoted to a new line, though the in-feed notes don't yet detail it.
◆Prediction
Expect 0.25.x to continue the invoice-resilience and operability focus, with detailed release notes following the tag; the next feed entries are likely 0.25.x bug-fix points.

◆Recent moves

    New 0.25.0 minor line (detailed notes not in feed)

    Tags the new 0.25.0 minor line after a long 0.24.x series. The feed entry contains only the maven-release tag, so the detailed changelog isn't published here — the milestone is the line cut itself rather than any documented change.

    Invoice failure handling: retries, account parking, logging (0.24.18)

    Hardens invoice processing: retries, parking accounts on unrecoverable failures (toggleable via property), and uniform WARN logging across failure paths. Real reliability work on the billing core.

    Bug fixes plus requestedDate credit parameter (0.24.17)

    Mostly bug and typo fixes (account BCD state, migration timestamps), plus a small requestedDate query parameter on the credit resource. Routine maintenance.

    Multi-tenant record indices and subscription/catalog fixes (0.24.16)

    Bug fixes alongside a database migration adding tenant_record indices across all core and history tables — a meaningful multi-tenant query-performance improvement. Fits the operability-hardening arc.

    Config-source visibility, table export, polling-queue default (0.24.15)

    A broad fix release plus operability gains: extra-table export, visibility into where each config property originates, and a default switch of the persistent bus to polling mode. Incremental but genuinely operator-facing.
