03 / Research limits

What the documents do not establish.

  • No individually numbered eClinicalWorks hotfix verified from the downloaded files.
  • The API note specifies build baselines 12.0.2.04000407 and 12.0.3.04009267 (or higher), then calls for the latest cumulative patch. It does not name a separate patch/hotfix package identifier.
  • The Open Developer Portal website version 4.0.7 and HL7 specification 2.5.1 were not used as EHR versions.
