+## Python 3.15 final
 
-Python 3.10–3.14 remains the supported stable range. These preview checks do not
-establish compatibility with Python 3.15 final, free-threaded builds, or macOS
-on this preview.
+The public stable **Fullbleed 2.5.34** wheel is checked on **CPython 3.15.0 final**
+on Windows x64, Linux x64, and Intel and Apple-silicon Macs. Use the ordinary
+installation command above.
+
+Each platform's job verifies the PyPI wheel and matching release source, runs
+the complete Python suite and isolated API/CLI checks, and compares generated
+PDFs and previews byte for byte with the same wheel on Python 3.10. The Linux
+job also checks installation in the official `python:3.15-slim` container with
+networking disabled.
+
+The [coverage note and retained evidence](https://github.com/fullbleed-engine/fullbleed-official/blob/master/docs/python-compatibility.md)
+describe the exact checks and the explicit skip for an unavailable legacy
+subinterpreter API. This qualification covers standard-GIL builds; free-threaded
+builds and subinterpreters remain outside its scope.
+
+The [earlier rc3 checks](https://github.com/fullbleed-engine/fullbleed-official/actions/runs/37720487567)
+remain available as historical evidence.
