1.436.0

Minor Changes

• #5083 d576bec Thanks @61465! - Opt-in WebView bot heuristic for #2921.
  • posthog-js/customizations exports a new isLikelyWebViewBot(ua) helper that flags the UA pattern described in #2921 (a Chrome/... token without the usual AppleWebKit/* + Safari/* co-markers that real Chrome always sends). Wire it into before_send to tag or drop the matching events — see isLikelyWebViewBot JSDoc for a usage example. Default SDK behaviour is unchanged; the helper is tree-shaken out unless you import it.
  • @posthog/core keeps isBlockedUA and DEFAULT_BLOCKED_UA_STRS byte-for-byte compatible, and gains session-level memoisation of isBlockedUA results keyed on (ua, customBlockedUserAgents), so repeat calls within the same session are O(1). (2026-10-05)
