## Project Status
**Stable** across all 3 signals i.e. `Logs`, `Metrics`, and `Traces`.
See [Spec Compliance
Matrix](https://github.com/open-telemetry/opentelemetry-specification/blob/main/spec-compliance-matrix.md)
to understand which portions of the specification has been implemented in this
repo.
## Supported C++ Versions
Code shipped from this repository generally supports the following versions of
C++ standards:
* ISO/IEC 14882:2014 (C++14)

Please note that supporting the [C Programming
of the current project.
## Supported Development Platforms
Our CI pipeline builds and tests on following `x86-64` platforms:
| Platform | Build type |
|---------------------------------------------------------------------|---------------|
| ubuntu-22.04 (GCC 10, GCC 12, Clang 14) | CMake, Bazel |
| ubuntu-20.04 (GCC 9.4.0 - default compiler) | CMake, Bazel |
| ubuntu-20.04 (GCC 9.4.0 with -std=c++14/17/20 flags) | CMake, Bazel |
