Version Compatibility and Conformance

Zowe Extensions Compatibility Recommendations:

• Verify your Vendor extensions have earned Zowe v3 Conformance (conformance assures interoperability)
• Alternatively, (not recommended) verify interoperability with the Vendor

​

Vendor Support Offerings:

• All Zowe v2 Support Providers must re-apply to re-affirm their conformance for Zowe v3. Comprehensive Support Providers MUST support ALL new Zowe Core components introduced with v3 (Zowe Extensions are excluded).

Zowe V3 Feature Details

Imperative:

Removed the following previously deprecated items:

• flattenCommandTreeWithAliases() -- Use CommandUtils.flattenCommandTree() instead
• AbstractAuthHandler.getPromptParams() -- Use getAuthHandlerApi() instead
• BaseAuthHandler.getPromptParams() -- Use getAuthHandlerApi() instead
• promptForInput() -- Use the asynchronous method readPrompt() instead
• promptWithTimeout() -- Use readPrompt instead which supports more options
• Imperative.envVariablePrefix -- Use ImperativeConfig.instance.envVariablePrefix instead
• pluginHealthCheck() -- Plugins that want to perform a health check can specify the pluginLifeCycle property to load a class from the plugin. The plugin can implement the postInstall() function of that class to perform a health check, or any other desired operation.
• IProfOpts.requireKeytar -- removing the default implementation of require("keytar") from the caller app's node_modules folders
