Release Notes

v5.9.4 on the GitHub

New Features


New Security

Implemented possibility to install WebStudio in two different security modes: Single-user and Multi-user. In a Single user mode only one user who is currently logged in on the computer can work in OpenL Tablets WebStudio. Single user mode is set by default and does not require additional settings. Multi-user mode enables multiple users to work in OpenL Tablets WebStudio and supports a security mechanism restricting access to certain product functions based on user access rights. Administrator can manage users and groups via UI. Running WebStudio in Multi-user mode requires external database installation, see details in the OpenL Tablets - Installation Guide in the ‘Configuring External User Database’ section.

User Management

Added a new feature designed to manage WebStudio users via UI in the Multi user mode. The user access in the WebStudio is based on users and user groups. All privileges are assigned to a group and will be granted to users after they are included in that group.

Multiple Production Repositories

Implemented possibility to add several production repositories via WebStudio UI. Now user can deploy a project to multiple repositories.

Project Versioning

Added business dimension properties to a rule project. All project modules, folders and files inherit the project properties that can be changed manually.

Added the following System properties to a project: ‘createdBy’ / ’createdOn’ and ‘modifiedBy’ / ’modifiedOn’.

Revision numeration has been changed: now a project revision number consists of one digit.

Added possibility to comment a new project revision: the user can enter any useful information as Comments when saving a new project revision.

  • WebStudio: New default User Workspace location.

    In previous releases WebStudio uses two different locations for user workspace:

    - [OPENL_HOME]/local-workspace - for local users (logged as LOCAL when WebStudio is deployed on the local machine)

    - [OPENL_HOME]/user-workspaces/[USERNAME] - for remote users (when WebStudio is deployed on the remote machine)

    In this release we redefined user modes. Now WebStudio can be deployed in two modes: Single-user and Multi-user (see above).

    Both of them use the same workspace location - [OPENL_HOME]/user-workspace.

    So move please projects from the old locations to the new one:

    -> [OPENL_HOME]/user-workspace - for Single-user mode (projects will be located in the root)

    -> [OPENL_HOME]/user-workspace/[USERNAME] - for Multi-user mode (projects will be located in the [USERNAME] folder)

    Notes: If you use a custom location for user workspace, configure it please again via Administration UI.
