v1.378.0

Compare Source

1.378.0

Minor Changes

• #​3688 8181354 Thanks @​pauldambra! - feat(persistence): add persistence_save_debounce_ms config option to coalesce rapid storage saves into a single write. Setting a positive value debounces writes to localStorage/cookie by that window; the in-memory props object still updates synchronously so within-tab reads see the latest values immediately, and pending writes flush on beforeunload and pagehide so no state is lost on tab close. Cross-tab storage events are reduced proportionally to the debounce window. Defaults to 0 (no debouncing) for backwards compatibility. On pages that capture many events per second, 250 is a reasonable starting point. The new 2026-05-30 config default opts into persistence_save_debounce_ms: 250 automatically.

v1.377.0

Compare Source

1.377.0

Minor Changes

• #​3708 3d4a76f Thanks @​pauldambra! - Detect Brave (desktop, Android, iOS), Vivaldi, Yandex, Naver Whale, DuckDuckGo, Pale Moon, and Waterfox so users on these browsers no longer get bucketed as Chrome or Firefox.

  detectBrowser / detectBrowserVersion now accept an optional third argument, BrowserDetectionHints, with a brave flag (set when navigator.brave exists). The browser SDK populates this automatically to catch desktop / Android Brave, which is Chromium-based and carries no UA marker. Brave on iOS is picked up purely from the Brave/ UA marker — WebKit doesn't ship navigator.brave. The original two-argument signature still works for non-DOM callers. (2026-06-01)

Patch Changes

• #​3703 f3cc6fa Thanks @​marandaneto! - Disable/no-op initialization paths instead of throwing or sending requests when PostHog project tokens are missing or blank.

v1.376.6

Compare Source

1.376.6

Patch Changes

• #​3687 663e250 Thanks @​pauldambra! - fix(persistence): skip the storage write when the serialized props are unchanged. Callers spam save() after every property change, and many of those changes leave the serialized payload identical (e.g. resetting a value to its current value). Writing identical bytes to localStorage still fires a cross-tab storage event in every same-origin tab, where Chrome allocates the payload buffer in mojo IPC even though no listener reacts. Now save() compares the serialized payload against the last successful write and bails out when nothing changed.
