Every captured event now carries $recording_status plus the replay trigger and buffered $sdk_debug_* properties, with the remaining session replay debug properties attached to SDK events at most once every 30 seconds, reading native replay state from @posthog/react-native-plugin 2.12.0 or newer. Also bumps @posthog/core to 1.60.1.

Regex flag handling now falls back instead of returning inconsistent local results for Unicode and advanced patterns. Also bumps posthog-node to 5.57.1 and @posthog/core to 1.60.1.

Survey rating scales that start at 1 now reject a prefilled rating of 0. The IE11 Math.trunc and Number.isInteger polyfills ship only in array.full.es5.js, so modern bundles no longer trigger Lighthouse's Legacy JavaScript audit.

The client privacyMode option now applies to AI integrations, keeping prompts out of errors, provider metadata, and OTel spans, and MCP tool credentials are redacted. Regex handling now falls back instead of returning inconsistent local results for Unicode and advanced patterns.

Query params are now read with form-encoding rules: an encoded plus (%2B) stays as + instead of becoming a space, and values containing = are no longer cut off, fixing UTM, click ID, and search keyword properties like utm_term=c%2B%2B. Also bumps @posthog/browser-common to 0.9.10.

When processing or uploading public source maps fails and sourcemaps.deleteAfterUpload is enabled (the default), the maps are now deleted instead of shipping in the build output; setting deleteAfterUpload to false keeps them and retries the upload at the end of the build.

Refusal text from OpenAI chat completions, streamed or not, is now captured in $ai_output_choices instead of an empty output.

Autocapture logic is now shared across browser SDKs while preserving existing event capture behavior, alongside a dependency bump to @posthog/browser-common 0.9.9.

The Conversations widget now comes back after reset() and after a cookieless on_reject visitor calls opt_in_capturing(), instead of staying unavailable until the next page load. Also, with debug: true set, capture() now logs why it dropped an event, whether capturing is disabled or the user agent is a bot.

evaluateFlags() snapshots now expose flags local evaluation could not resolve via unresolvedFlags, tag reads with local_evaluation_inconclusive, and warn once about unsupported flag definitions. Conditions mixing an uncheckable filter with a non-matching filter now resolve locally as no match instead of falling back to a server request.
