+WASI support is defined in :pep:`816`.

+====== ==== ========
+
+All versions prior to Python 3.15 predate :pep:`816`. The version support for
+those earlier versions is based on what was supported when that PEP was
+written.
+
+WASI was a tier 3 platform for Python 3.11 and 3.12, and became a tier 2
+platform starting with Python 3.13.
+
+WASI 0.2 support has been skipped due to lack of time, to the point that it was
+deemed better to go straight to WASI 0.3 instead. This is based on a
+recommendation from the `Bytecode Alliance <https://bytecodealliance.org>`__.
+
+WASI SDK 26 and 27 have a
+`bug <https://github.com/WebAssembly/wasi-libc/issues/617>`__ which causes
+CPython to hang in certain situations, and so they have been skipped.
