+## Creating a Release (Maintainers)
+Releases are built and published automatically by the [Release](.github/workflows/release.yml) GitHub workflow
+whenever a version tag is pushed to the repository.
+
+1. Update `projectVersion` in `gradle.properties` to the new version, following the naming convention described in
+that file (e.g. `0.6.2-alpha-1`, `0.6.2-beta-1` or `0.6.2`).
+2. Commit and push the change to `master`.
+3. Create and push a tag that matches the version with a leading `v`:
+```
+git tag v0.6.2-beta-1
+git push origin v0.6.2-beta-1
+```
+
+The workflow then:
+* Verifies that the tag matches `projectVersion` in `gradle.properties` and fails if it does not.
+* Builds and tests the code, then creates the release zips for Linux, Mac and Windows (x86-64 and aarch64).
+* Creates a GitHub release titled `Version <version>` with auto-generated release notes (a "What's Changed" list of
+the PRs merged since the previous version tag), and attaches the six zip
+files plus a `SHA256SUMS` checksum file.
+* Marks tags containing a dash (alpha and beta versions) as pre-releases. Tags without a dash become full releases.
+
+If the workflow fails part way through, fix the problem and re-run it from the Actions tab. It resumes from the
+draft release left behind. It won't modify a release that has already been published. To rebuild a published
+release, delete the release and the tag on GitHub, then push the tag again.

+/**

+ *
+ * This is a port of the JTransforms FloatFFT_1D mixed radix complex transform path.  JTransforms allocates a new
+ * 2N float scratch array on every mixed radix transform, which creates significant garbage collection pressure when
+ * the transform runs at block rate (e.g. the polyphase channelizer IFFT).  This implementation pre-allocates the
+ * scratch buffer once and reuses it for each transform.
+ *
+ * Results match JTransforms FloatFFT_1D complexForward() and complexInverse(): the forward transform uses the
+ * exp(-j...) kernel, the inverse uses exp(+j...), and the inverse optionally scales by 1/N.  Twiddle factors are
+ * calculated in double precision, so results can differ from JTransforms in the least significant bits.
+ *
+ * Samples are interleaved complex: a[offset + 2k] = Re[k] and a[offset + 2k + 1] = Im[k] for 0 <= k < N.
+ *
+ * Note: this class is NOT thread-safe since it reuses an internal scratch buffer.  Use one instance per thread.
