Release notes

  1. Major RFCs approved (check the site). The DSU APIs proven stable in OpenDSU SDK will be preserved in all future versions.
  2. Release 2.0.0 declares the "legacy" DSU APIs stable. However, we changed the caching mechanism of the DSU (removed any long-term caching). We introduced "startOrAttachBatch" as the best method for working in batch mode.
  3. Release 2.0.1 is declared the first production-ready release. (It does not have changes on public APIs but has many stability and security-related fixes).
