  Seyond publishes no product changelog or release-notes page on seyond.com. The only dated, public
  change record is the GitHub Releases stream on the two first-party repositories, each release carrying
  a written note. Recorded here verbatim-in-substance from the GitHub Releases API.
scheme: semver-like
versioning_note: >-
  The SDK uses a three-part major.minor.patch tag (3.103.13), with an in-tree SDK_VERSION file that
  appends a build timestamp (3.103.4.20250910092521). Release tag naming is inconsistent — the newest is
  prefixed "release-" (release-3.103.13) while earlier ones are bare (3.103.10). The ROS driver uses a
  separate, conventional v-prefixed semver line (v1.0.3) and pins the SDK as a submodule.
