This page describes the lifecycle of Primer's SDKs: the named stages every version moves through, what Primer commits to at each stage, and the rules that govern transitions. The policy applies to the **iOS**, **Android**, **Web**, and **React Native** SDKs, at the **major version** level — minor and patch versions inherit the stage of their parent major. ## Lifecycle stages Every supported major version is in one of five stages at any given time. | Stage | Badge | Minimum duration | What Primer commits to | Breaking changes | | ------------------- | ----------- | -------------------------------------------- | --------------------------------------------------------------------------------------------------------------------------------------------- | --------------------------------------------------------- | | Beta | `BETA` | No minimum | Early access for design partners. The SDK may change without notice between Beta releases. | Allowed, documented in the changelog. | | Release Candidate | `RC` | No minimum | Support for RC testers. Feature-complete and intended for integration validation ahead of GA. | Unlikely, but possible. | | Generally Available | `GA` | Until its successor reaches `GA` | Full support: bug fixes, security patches, and new payment-method compatibility. | Avoided. A migration path is provided if one is required. | | Supported | `Supported` | At least 12 months after the `GA` stage ends | Critical security patches only. No new features. | None — the version is frozen. | | End of Life | `EOL` | — | No support and no patches. Version removed from public documentation. In-SDK runtime warning displayed. Package registries marked deprecated. | — | ## How versions move between stages The lifecycle is **successor-anchored**, not calendar-anchored. A `GA` version does not expire on a fixed date. It transitions to `Supported` only when the next major version of the same SDK reaches `GA`, and it transitions to `EOL` no sooner than 12 months after that point. ```mermaid theme={"dark"} gantt title Example timeline (illustrative) dateFormat YYYY-MM-DD axisFormat %b %Y section SDK v3 Beta :v3b, 2025-01-01, 60d RC :v3rc, 2025-03-01, 30d GA :v3ga, 2025-04-01, 365d Supported (min. 12 months) :crit, v3s, 2026-04-01, 365d section SDK v4 Beta :v4b, 2025-11-01, 60d RC :v4rc, 2026-02-01, 30d GA :v4ga, 2026-04-01, 365d ``` ## Current status The table below shows the current stage of each supported major version. It is updated as versions transition between stages. | SDK | Major version | Stage | Reference | | ------------ | ------------- | ----------- | -------------------------------------------------------------------------------------- | | iOS | v3.x | `BETA` | [iOS Primer Checkout reference](/sdk/ios-checkout/v3.0.0-beta/configuration/settings) | | iOS | v2.x | `GA` | [iOS SDK v2 installation](/sdk/ios/v2.x.x/installation) | | Android | v3.x | `BETA` | [Android Primer Checkout installation](/sdk/android-checkout/v3.0.0-beta/installation) | | Android | v2.x | `GA` | [Android SDK v2 installation](/sdk/android/v2.x.x/installation) | | Web | v1.x | `GA` | [Web Primer Checkout reference](/sdk/primer-checkout-web/sdk-reference-overview) | | Web | v2.x | `Supported` | [Web SDK v2 overview](/sdk/web/v2.x.x/primer-checkout/overview) | | React Native | v2.x | `GA` | [React Native SDK v2 installation](/sdk/react-native/v2.x.x/installation) | For the authoritative list of released versions within each major, see each SDK's [changelog](#related). ## Deprecation signals Versions approaching or past `EOL` surface the following signals: * **Package-registry deprecation flags** on npm, CocoaPods, Maven Central, and Swift Package Manager. * **In-SDK runtime warnings** emitted from `Supported` versions onward. * **Changelog and release-notes entries** at each stage transition. These signals indicate lifecycle state but are not themselves the state. The authoritative stage for any major version is the one listed in [Current status](#current-status). ## Enforcement Enforcement of the SDK lifecycle is **API-driven**, not SDK-side. Primer does not actively block or disable calls from `EOL` SDKs at the SDK layer. * When an `EOL` SDK relies on an underlying API that is itself no longer supported, calls will stop working as that API reaches its own end of life (see [API lifecycle](/api-reference/get-started/api-lifecycle)). This is the expected enforcement path. * When an `EOL` SDK relies on an API that remains supported, calls will continue to function. However, Primer offers no compatibility, security, or stability guarantees for `EOL` versions, and support tickets against them will not be accepted. ## Vocabulary `Supported` is a specific lifecycle stage on this page, not a general adjective. A version in `GA` is actively supported, but it is not in the `Supported` stage. When referring to a version's state, prefer the badges — `GA`, `Supported`, `EOL` — over prose. `Deprecated` is a signal Primer emits (via package-manager flags, release notes, and in-SDK runtime warnings); the underlying lifecycle state is still one of the five named stages above. ## Related * [API lifecycle](/api-reference/get-started/api-lifecycle) — the same model applied to the Primer API. * [iOS SDK changelog](/changelogs/ios-sdk) * [Android SDK changelog](/changelogs/android-sdk) * [Web Primer Checkout changelog](/changelogs/primer-checkout-sdk) * [Web SDK changelog — v2](/changelogs/web-sdk) * [React Native SDK changelog](/changelogs/react-native-sdk)
