03/12/2020

Compatibility:

Improvements:

• The directory tree now has a button for opening the context menu.

Features:

• Analogous to SpaceObServer the Web Access has now an Overview Panel. The Overview Panel shows details of a selected Scan.
• In the table ‘Details’ a context menu can be opened via right-click which provides an option to add a note to a folder or file. You can add notes to multiple entries by selecting multiple rows. These notes are visible both in Web Access and SpaceObServer in the column ‘Note’.
• In the directory tree containers can now be marked via checkboxes.

Improvements:

• Some internal adjustments have reduced the load times of the SpaceObServer Web Access in many areas. The usability and reactivity was noticeably increased.
• The selection of units and size units for the directory tree now loads much smoother.
• The selection of options in the charts, history and distribution now loads much smoother.
• Debug logs can now be sent, downloaded and deleted via the administrator backend.
• Login with a user of the "Restricted" role could possibly lead to a long delay at the beginning of the session. This issue has been resolved.

07/10/2018

New Bitness:

• The Web Access changes to 64 bit. A 32 bit version is no longer available.

Permissions:

• Web Access now provides a role system. The role system configuration is located in the administrator backend. A role connects multiple Windows accounts or groups with permissions. The Web Access supports nested groups. A user can only log into Web Access when he belongs to a role, either through a connected Windows group or directly through his user account. When a user belongs to multiple roles, then all activated permissions of all belonging roles will be additively combined. Three recommended roles are available as presets. It is possible to add, edit, delete and clone roles. The setup provides an input mask to add users to the administrator role.
• Web Access caches the group membership of a logged in user for 15 minutes. When the group membership is changed in the Active Directory, then Web Access applies the changes after 15 minutes. In the administrator backend, in the tab 'Information', there is a button to delete the cache and force a reload. After that, Web Access refreshes the cached groups from the Active Directory, during login.
• When SpaceObServer scans with an activated ACL (Access Control List) and Web Access has enabled the respective option, the displayed data is filtered by the ACL. An ACL-filtered Scan has a blue filter icon as indicator in the folder tree.
• The setup dialog for the configuration of the admin role now shows a warning when the currently logged-in user is not a member of the administrator role.
• In the administrator backend, the tab 'Users' has been renamed into 'Licenses'. The controls to register users or set filters to users are no longer available in this tab. The role system is now responsible for these purposes. The tab 'Licenses' now only summarizes all information about used licenses.

New Export Functions:

• It is now possible to export the data in tables in CSV, Excel, TXT, or PDF format.
• It is now possible to export the images in the tabs 'Charts', 'History' and 'Distributions' in PNG, JPEG, Bitmap, and GIF format.

Tables:

• In the tabs 'Extensions', 'Users' and 'Top100' a dropdown menu provides checkboxes to hide/show columns, these settings are persisted across sessions.
• The dropdown for tables now provides the horizontal order of columns, these settings are persisted across sessions.
• In the tabs 'Extensions', 'Users', and 'Top100' the tables show the data noticeably faster.
• Tables now load only data from the server for fields visible in the window, therefore tables with many datasets display the first results much faster.
• In the tab 'Extensions', the data in groups is only loaded from the server when users expand groups (Lazy Load). This reduces the initial loading time of the table.
• If users select rows in tables and switch between the tabs, the rows remain selected.

Charts:

• The history provides new additional information: 'Size', 'Allocated', and 'Average'.
• The tab 'Charts' provides the 'Tree Map' now.
• The tab 'History' provides a button to enable/disable a grid now.
• When users switch between the tabs 'Charts' and 'History' the client does not reload the images from the server again, showing the images from the cache instead.

Changed Compatibilities:

• Web Access requires an installed SpaceObServer with at least version V6.x, which was released on 11th of November, 2017.

Bug Fix:

• In the tab 'Details' the columns 'Last Modified' and 'Last Accessed' sometimes displayed the data with a noticeable delay.
• Switching between the tabs 'Extensions', 'Users', 'Top100' and 'Duplicate Files' sometimes resulted in long waiting times, because server side processes blocked each other.
• In the tables sometimes negative values were colored green. All negative values are red now.
• The sorting of some table columns with decimal places was wrong.
• When users switched the selection of folders in the folder tree between two scans, the 'History' sometimes displayed no data.
• When SpaceObServer made an update scan, the tab 'Extensions' didn´t show the updated data in the entire session. A re-login was required. The table now shows the updated data after pressing the F5 button.
• In the tab 'Charts' sometimes the identifier of the x-axis was missing.

Miscellaneous:

• The icons and the appearance have been adapted analogously to SpaceObServer.
• There a two new items added to the Windows Start Menu: "Configure Administrator Role" and "Configure Database".
• Some minor improvements and bugfixes have been incorporated.

02/27/2018
