🧭 Overview​

This release brings functional extensions for the vNext Runtime Platform, flexible structure in view management, new functions for the script engine, and changes that ensure consistency in schema structure.
Additionally, subFlow view override support, new system tasks, and configuration updates are also provided with this release.

🚀 Major Updates​

1. Schema Enhancements​

Extensive tightening has been implemented on schemas in this release:

  • target has been removed from the View schema.
  • Adjustments have been made to common fields such as timer, rule, view in Workflow schemas.
  • New View Schema:
{
  "view": {
    "extensions": ["ex_1", "ex_2"],
    "loadData": true,
    "view": {
      "key": "",
      "version": "",
      "domain": "",
      "flow": "sys-views"
    }
  }
}

For complete schema details, you can refer to the release-v0.0 branch in the vnext-schema repository.

2. SubFlow View Override Support​

Custom view definitions can now be made in subflow calls. This allows customized screens to be used in different subflows.

Example Usage:

"subFlow": { 
  "type": "S", 
  "process": { 
      "key": "password-subflow", 
      "domain": "core", 
      "version": "1.0.0", 
      "flow": "sys-flows" 
  }, 
  "mapping": { 
    "location": "./src/PasswordSubflowMapping.csx"
  }, 
  "viewOverides": [ 
    { 
      "account-selection-view": { 
        "key": "account-selection-new-view",
        "domain": "core",
        "version": "1.0.0",
        "flow": "sys-views"
      } 
    }
  ] 
}

3. ScriptBase Extensions​

New functions have been added. ScriptBase now provides comprehensive helper methods for both Dapr Secret Store and Configuration operations.

New Featured Functions:

  • GetSecret, GetSecretAsync, GetSecrets, GetSecretsAsync
  • LogTrace, LogDebug, LogInformation, LogWarning, LogError, LogCritical
  • GetConfigValue, GetConnectionString, ConfigExists

These functions are located in BBT.Workflow.Scripting.Functions.ScriptBase.

4. System Tasks​

Newly added reusable system tasks:

Script Task​

{
  "key": "script-task",
  "domain": "core",
  "version": "1.0.0",
  "flow": "sys-tasks"
}

Notification Task​

Enables sending notifications through the Hub:

{
  "key": "notification-task",
  "domain": "core",
  "version": "1.0.0",
  "flow": "sys-tasks"
}

🧩 Bug Fixes​

  • Transition Bug:
    Fixed the issue where Instance Data could not be written when the payload was empty during transition.

⚠️ Breaking Changes​

  • View schema structure has been changed (new extensions and loadData fields).
  • Old extension system components (data, view, available-transition) have been removed.
  • View endpoint response structure has been changed:
// Old:
<returned content directly>

// New:
{
  "type": "json",
  "content": "....",
  "key": "account-creation-view"
}

🔧 Configuration Updates​

New vnext.config.json example:

{
  "runtimeVersion": "0.0.18",
  "schemaVersion": "0.0.17"
}
