Zowe installation and packaging

• Component installation can now print stdout of install scripts. (#3361)

Zowe Application Framework

ZSS

• /datasetMetadata now returns prime, secnd, and space fields for showing the primary and secondary extent sizes and the unit type for them. (#582)
• ZSS data set creation API now supports space values of BYTE, KB, and MB, instead of just CYL and TRK.

Zowe Common C

• fileCopy now copies with the target having the permissions of the source, as opposed to the previous 700 permissions.

Zlux App Manager

• Added new isSingleAppModeSimple() to iframe-adapter to differentiate between standalone mode and simple standalone mode.
• Replaced existing snapshot preview with lighter UI to significantly increase multi-app Desktop performance.

Zlux Server Framework

• Added support for zowe.verifyCertificates=NONSTRICT. (#468)
• Allow dataservices to pass CAs into the call() function. (#462)

Zlux Editor

• Renamed openFile to openBuffer in editor-control.serverice.ts.

Zowe API Mediation Layer

• A unique authentication cookie name has been added for multi-instance deployment (#2812) (6654271), closes #2812.

Zowe CLI

Zowe CLI (Core)

• Updated Imperative to add --prune option to zowe config secure command to delete unused properties. (Imperative #547)
• Added range option to zos-files view uss-file command.

Imperative CLI Framework

• Added --prune option to zowe config secure command to delete unused properties. (#547)

• Added credMgrOverride property to IProfOpts interface that can be used to override credential manager in the ProfileInfo API. (Zowe CLI #1632)

• Deprecated the requireKeytar property on the IProfOpts interface. Use the credMgrOverride property instead and pass the callback that requires Keytar to ProfileCredentials.defaultCredMgrWithKeytar.

• Added AbstractPluginLifeCycle to enable plug-ins to write their own postInstall and preUninstall functions, which will be automatically called by the Zowe plug-in's install and uninstall commands.

• Added pluginLifeCycle property to IImperativeConfig to enable a plug-in to specify the path name to its own module which implements the AbstractPluginLifeCycle class.

• Added a list of known credential manager overrides to Imperative. When a credential manager cannot be loaded, a list of valid credential managers displays in an error message.

• Added a CredentialManagerOverride class containing utility functions to replace the default CLI credential manager or restore the default CLI credential manager. Plug-ins which implement a credential manager override can call these utilities from their AbstractPluginLifeCycle functions.

• Added documentation Overriding_the_default_credential_manager describing the techniques for overriding the default CLI credential manager with a plug-in.

z/OS FTP Plug-in for Zowe CLI

• Updated example of upload file-to-data-set command in the plug-in help.

Zowe Explorer

• Added a new Zowe Explorer setting, zowe.logger, with a default setting of INFO to allow users to select the level of logging they want to see. Logging levels range from TRACE (most verbose) to FATAL (only fatal).

• Added an output channel, Zowe Explorer, for logging within VS Code's Output view so users can view Zowe Explorer logs within VS Code. The log level is set by the new Zowe Explorer setting, zowe.logger.

• Opening a dialog for Upload or Download of files will now open at the project level directory or the user's home directory if no project is opened. (#2203)

• Updated linter rules and addressed linter errors throughout the codebase. (#2184)

• Added the new setting zowe.files.logsFolder.path that can be used to override the Zowe Explorer logs folder if the default location is read-only. (#2186)

Bug fixes

Zowe Version 2.8.0 contains the bug fixes that are described in the following topics.

Zowe installation and packaging

• Component environment variables will not be aliased to the configs shorthand when the component had a configure script, but not a validate script, and zowe.useConfigmgr was enabled.

ZSS

• Changed conflicting message IDs in the ZIS dynamic linkage base plug-in.

Zowe Common C

• fileCopy would not work when convert encoding was not requested. The destination file would be created, but without the requested content.
