Deploy Dialog

  • FEAT: set deployment-source to Camunda Modeler (#1153)


  • FEAT: add ability to reference local assets via logical paths (dcf2bc0b)
  • FEAT: recognize plug-ins in {basePath}/resources/plugins (#597)
  • CHORE: gracefully handle plugin load failures (#1180)
  • CHORE: enforce unique names (#1180)

  • FIX: give plug-ins stored in {userData} access to local assets (#1135)

Breaking Changes

  • The global plug-in helper getPluginPaths() did not work reliably and got deprecated. Use logical paths of the form app-plugins://{pluginName}/{pathToResource} to reference static plug-in assets (1de7af5a).
  • The global plug-in helper getModelerPath() was removed without replacement (1de7af5a).
  • Rewriting the modeler changed most CSS selectors outside the actual diagram editors / properties panels. This may break plug-ins that monkey patch the application styles.
  • To improve compatibility with external tools, we now prevent negative coordinates by aligning to (0,0) on diagram save. This results in slightly more noise in actual file changes (#1096).
