Recent updates
posthog-node@5.37.0
2026-06-12posthog-node@5.37.0 adds server-matching behavior for the feature flag `early_exit` condition option during local (client-side) evaluation. When a condition group's property filters match but the rollout percentage excludes the user, evaluation now stops early and returns `false`.
Featuresposthog-react-native@4.47.0
2026-06-12posthog-react-native@4.47.0 adds opt-in native iOS and Android crash autocapture via the optional @posthog/react-native-plugin. It also extends Expo build tooling so crashes can be symbolicated when you enable native symbol upload (including an option to include native source).
Features@posthog/react-native-plugin@2.0.1
2026-06-12This release (2.0.1) is described as a patch that changes native React Native error capture to avoid duplicate $exception events, and it updates session replay behavior by applying the configured session replay settings at native SDK setup time even if replay starts disabled. These are both aimed at correcting unexpected analytics behavior and improving session replay configuration consistency.
posthog-js@1.386.6
2026-06-11This patch updates the product tours behavior in posthog-js so cached product tours data is dropped when product tours become disabled. Specifically, when remote config or the disable_product_tours option resolves product tours to disabled, the SDK stops the in-session tour manager and clears the persisted tours cache to prevent stale data from being carried across persistence writes and cross-tab storage events.
posthog-js@1.386.5
2026-06-11Release posthog-js@1.386.5 primarily documents a replay fix for rrweb session-id rotation, preventing silent recorder teardown during active capture. However, the actual code diff includes additional SDK surface changes (notably the new MCP integration export and multiple configuration/type default updates) that are not covered in the provided release notes.
BreakingFeaturesposthog-js@1.386.4
2026-06-11posthog-js@1.386.4 includes a replay fix where seeking/fast-forwarding past pages using CSS `scroll-behavior: smooth` no longer animates via the inherited smooth behavior. Instead, sync scrolls and full snapshot rebuilds apply `behavior: 'instant'` so the document and UI content stay in view during replayer seeking.
posthog-react-native@4.46.32
2026-06-11posthog-react-native@4.46.32 ships with only documented dependency bumps in the release notes (@posthog/types and @posthog/core). However, the underlying code diff includes multiple behavioral changes across conversations widget DOM handling, session/cross-tab persistence logic, and AI gateway misconfiguration warnings.
Features@posthog/webpack-plugin@1.5.22
2026-06-11The published release notes for @posthog/webpack-plugin@1.5.22 only mention a patch dependency update to @posthog/core@1.32.3. The actual code diff for this release includes multiple substantive behavioral changes in posthog-js itself, including conversations widget DOM re-attachment across SPA navigations, cross-tab session-id rotation/adoption logic, and split-storage persistence optimizations.
@posthog/types@1.386.3
2026-06-11This release focuses on cross-tab session stability, changing how session rotation is decided when multiple tabs share localStorage. Instead of rotating when a single background tab becomes idle, a tab refreshes and adopts a sibling tab's session id when the sibling has kept the session alive, and emits onSessionId events with changeReason.crossTabAdoption.
posthog-node@5.36.17
2026-06-11Although the release notes for posthog-node@5.36.17 only mention a dependency bump for @posthog/core@1.32.3, the actual diff contains multiple significant behavior changes in the browser SDK. These include cross-tab session-id stability/adoption logic, changes to when split-storage group entries are rewritten, and a new SPA-navigation reattachment watcher for the Conversations widget.
BreakingFeaturesposthog-js@1.386.3
2026-06-11posthog-js@1.386.3 is a patch release focused on cross-tab session correctness, plus a UI fix for the Conversations support widget disappearing after SPA navigations that replace document.body. It also improves split-storage behavior by preventing per-request metadata updates from dirtying and re-broadcasting large group entries on every /flags or /surveys load.
posthog-js-lite@4.6.62
2026-06-11This release introduces multiple behavioral fixes in the browser SDK: the Conversations widget is now re-attached automatically after SPA navigations that replace document.body, and session handling across tabs is hardened to prevent premature background-tab idle rotations. It also changes persistence behavior for certain volatile metadata keys to avoid repeatedly rewriting large split-storage entries on every load.
Breaking@posthog/next@0.4.94
2026-06-11This release is a dependency-only patch update for @posthog/next. It bumps @posthog/core, posthog-js, and posthog-node to specific newer versions without listing any direct feature, bug fix, or API changes.
