What is Lemon Squeezy?
Lemon Squeezy ships fundamentals — localization, charts, webhook tooling — then goes quiet.
Lemon Squeezy's public changelog has been visibly idle for roughly nine months. The last shipped work centered on payment-platform fundamentals: 34-language checkout localization with no configuration required, MRR/ARR chart accuracy improvements, manual webhook simulation for developer integration, account-level 2FA, and partial refunds with credit notes.
What is Kill Bill?
Kill Bill cuts a new 0.25 line after a long 0.24.x reliability run
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.

Lemon Squeezy

Lemon Squeezy ships fundamentals — localization, charts, webhook tooling — then goes quiet.
◆ Current state
Lemon Squeezy's public changelog has been visibly idle for roughly nine months. The last shipped work centered on payment-platform fundamentals: 34-language checkout localization with no configuration required, MRR/ARR chart accuracy improvements, manual webhook simulation for developer integration, account-level 2FA, and partial refunds with credit notes.
◆ Where it's heading
The arc through 2024 and into mid-2025 was filling out merchant-of-record table stakes — international checkout, refund flexibility, security, integration ergonomics. Since then, the public surface has gone silent. That can mean a deliberate move toward larger less-frequent releases, focus on the parent company's roadmap (Stripe acquisition era), or genuine reduced cadence. The entries themselves don't disambiguate.
◆ Prediction
The next public update is unclear from the visible signal. If shipping resumes, the most natural extensions of the prior trajectory are subscription dunning workflows or richer tax/VAT automation atop the localized checkout.

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.
