## Version 12.5.0

### Added

* Support for multiple mobile cookie versions headers (`X-PX-AUTHORIZATION-V2` with priority over `X-PX-AUTHORIZATION`)
* Added `x-px-authorization-v2`, `x-px-original-token`, and `x-px-bypass-reason` headers to `page_requested` and `block` activities

### Fixed

* Fixed `X-PX-ORIGINAL-TOKEN` header reading bug. It now correctly reads from the request header instead of an unpopulated internal context variable
* Added `request_id` field to telemetry activity
* Added `window._pxCustomOnErrorMessage` support in block page template
