Kill Bill vs Purchasely: at a glance
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.
What is Purchasely?
Purchasely 6.0 overhauls the SDK's core — initialization, presentation, and purchase flow get a full rewrite.
Purchasely is an SDK for managing in-app subscriptions and paywalls on iOS, Android, and web. SDK 6.0 modernized the initialization model, screen presentation, action handling, and purchase flow control across all platforms — a major version that breaks backwards compatibility but aligns the SDK with current platform requirements. SDK 6.1 builds on this with a web-to-app redemption flow and proxy routing for environments where the Purchasely API is unreachable.

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.
Purchasely
2.5FINANCE
Purchasely 6.0 overhauls the SDK's core — initialization, presentation, and purchase flow get a full rewrite.
◆ Current state
Purchasely is an SDK for managing in-app subscriptions and paywalls on iOS, Android, and web. SDK 6.0 modernized the initialization model, screen presentation, action handling, and purchase flow control across all platforms — a major version that breaks backwards compatibility but aligns the SDK with current platform requirements. SDK 6.1 builds on this with a web-to-app redemption flow and proxy routing for environments where the Purchasely API is unreachable.
◆ Where it's heading
The 5.x series added screen orchestration (Flows), conditional visibility (Bring Your Own Screen), web checkout parity, and campaign tooling. The 6.0 reset cleans up the resulting complexity. The web-to-app redemption feature in 6.1 extends the funnel across platforms — subscribers who start on the web can redeem in the app and vice versa. This is a meaningful cross-platform monetization capability.
◆ Prediction
The next move is likely expanding web-to-app funnel analytics and deepening the server-to-server event model to support more complex subscription lifecycle scenarios (pauses, downgrades, family plans). The proxy routing feature in 6.1 suggests Purchasely is serving markets or enterprise environments with restricted network access.
