Public release status
Polyphase Float 0.20.0 is distributed under LGPL-3.0-or-later with a bounded
pre-1.0 contract for Linux x86-64 ELF LP64 and 64-bit GMP limbs. ABI epoch 1 and
libpolyphase_float.so.0 are retained. The production core is independent of
MPFR; the adapter and differential tests use MPFR optionally.
The release scope is the current reference for supported inputs, allocation behavior, resource limits, and review boundaries. The reader's manual provides the learning path and complete user reference; the 1.0 readiness record separates completed preparation from open promotion requirements. The semantic contract indexes the 437 core functions, while the allocation reference records the completed classifications and targeted lifecycle tests.
Use Qualification to reproduce validation. The resulting receipt records actual execution against an exact source snapshot; historical reports do not replace it. Claims and evidence explains how to interpret tests, mathematical arguments, and benchmark results.
The roadmap lists outstanding independent review and external reproduction requirements for a later 1.0 release. Source packaging and local qualification do not assert a remote commit, tag, or published release asset.
