name: Moore Threads Release Notes
description: >-
  Moore Threads publishes per-version release notes for its software products under
  docs.mthreads.com, with superseded versions preserved in a history_version tree. The notes are
  substantive — API counts added, compiler and platform support, validation matrices — but they
  are NOT DATED: no release note found carries a publication date, so the series can be ordered by
  version but not placed in time. There is no changelog of any kind for the AIBook speech APIs or
  the KUAE Cloud Coding Plan endpoint.
scheme: semver-ish per product line (major.minor.patch)
current_version: MUSA SDK 5.2.0
dated: false
dated_note: >-
  Release-note pages carry a version in the title and no date in the body. Recorded honestly rather
  than inferring dates from sitemap or crawl metadata.

api_changelog:
  published: false
  note: >-
    Neither the AIBook speech APIs nor the KUAE Cloud Coding Plan has any changelog. The ASR
    reference carries a single inline change marker — "2024/6/24 新增" against the English-language
    option — which is the only dated API change published anywhere on the estate.
