Quality levels
- Experimental - no quality expectations
- Early support - platform may not be available on the market yet
- Pre-Release - suitable for integration and testing, gathering customer feedback
- Beta - suitable for integration and broad testing
- Production - Beta + meets API-specific conformance requirements; suitable for production
- Maintenance - Reduced test frequency compared to Production, no longer recommended for new deployments. Reactive support for customers.
Known issues
- Opencl-clang bug: Invalid headers due to missing declaration of atomic_double impacting Atom-based platforms. Fix
Important changes
- igc revision update
