<Update label="v1.0.0" description="6 Aug 2026">
  `improvement`

  General release.
</Update>

<Update label="v0.1.3" description="6 Aug 2026">
  `description-fix`

  Removed the NCBI account settings URL from the API Key authentication description — the documentation card's character limit truncated it into a broken 404 link; the full link remains in the setup guide.
</Update>

<Update label="v0.1.2" description="3 Aug 2026">
  `description-fix`

  Clarified the Get Article Summaries and Get Articles descriptions so it is clear that summaries return bibliographic metadata only while full records include the abstract and complete data.

<Update label="v0.1.1" description="30 Jul 2026">
  `guide-changes`

  Fixed the NCBI API key setup guide — corrected the broken account-settings link, updated the Account settings navigation to the profile dropdown (with a matching screenshot), covered copying an existing key, and removed the duplicate No Authentication setup guide.
</Update>

<Update label="v0.1.0" description="28 Jul 2026">
  `new-connector`

  Initial PubMed (NCBI E-utilities) connector with 9 actions across articles, related, citations, search, history, and databases — optional API key auth, JSON/XML output, and esearch error refinement.
</Update>
