4.66.0

#4617 b73d15e Thanks @ablaszkiewicz! - Add experimental event release mode to React Native builds. Set releaseMode: 'event' on the posthog-react-native/expo config plugin (or export POSTHOG_RELEASE_MODE=event, or set posthog.releaseMode=event in android/gradle.properties) and the build uploads its Hermes source maps, iOS dSYMs and Android R8 mappings without binding them to a release. Each exception then resolves its own release from the $app_namespace / $app_version / $app_build the SDK already sends, instead of inheriting the release of the symbols its frames resolved against. Use it when two releases can ship identical JavaScript or identical native code: symbol ids are derived from content, so the default symbol-set mode makes both releases report whichever one uploaded first. An unrecognized mode fails the build rather than falling back. The Hermes upload needs posthog-cli 0.16.0 or newer, which carries --release-mode on its hermes commands; an older one fails the build and names the upgrade.
The Android mapping upload needs the com.posthog.android gradle plugin 1.5.0 or newer, which reads posthog.releaseMode. A fresh prebuild now injects 1.5.1. A project whose android/build.gradle already has the classpath line keeps its version, so bump that line to 1.5.0 or newer by hand, or prebuild with --clean. On 1.4.0 the mapping stays bound to a release while the Hermes maps do not. (2026-08-27)
