+## Project Status
+
+JsonCpp is a mature project in maintenance mode. Our priority is providing a stable,
+reliable JSON library for the long tail of C++ development.
+
+### Current Focus
+
+**Security:** Addressing vulnerabilities and fuzzing results.
+
+**Compatibility:** Ensuring the library builds without warnings on the latest versions of GCC,
+Clang, and MSVC.
+
+**Reliability:** Fixing regressions and critical logical bugs.
+
+### Out of Scope
+
+**Performance:** We are not competing with SIMD-accelerated or reflection-based parsers.
+
+**Features:** We are generally not accepting requests for new data formats or major API changes.
+
+JsonCpp remains a primary choice for developers who require comment preservation and support for
+legacy toolchains where modern C++ standards are unavailable. The library is intended to be a
+reliable dependency that does not require frequent updates or major migration efforts.

-### Special note
-
-The branch `00.11.z`is a new branch, its major version number `00` is to show
