Canvus 3.1.5

Released on Mar 22, 2022 - Recover corrupted server folder structure automatically. Canvus server versions from 2.7.3 to 2.7.6 might have corrupted the folder structure in a way that would cause home folders to disappear and canvases to move to \"Lost & Found\" folder on the server startup. The corruption bug was fixed in Canvus server 3.0.0, but if the data was corrupted in an earlier version, the problems could still appear in later versions.

This version fixes the folder structure if needed, moves canvases to their original locations, restores home folders and permissions and prevents the issue happening again in the future.

Canvus 3.0.0

Released on Jul 5, 2021

Canvus 3.0.0 is a new major release with lots of changes and new features.

Due to the introduced access control, Canvus 2.x and Canvus 3.0 are not compatible with each other. This means you can not use Canvus 2.x client to connect to Canvus Connect 3.0 server and you can not connect to Canvus 2.x server using a Canvus 3.0 client. All data is migrated on upgrade.

New user interface

This version of Canvus includes a redesigned new user interface, focused on making it easier to use both on laptop and video wall installations and addressing issues reported by users.

This release introduces a new title bar for canvas items, which can be used to name items on the canvas. It also includes upload progress of any file-based assets that are added to the canvas. The old widget menu on the right has been replaced by a new sidebar.

The new info panel shows additional information for the current user on the active canvas and its size has also been reduced based on user feedback.

Most of the dialogs and other UI widgets have been refreshed as well.

The new user interface changes the behavior of how canvas items are activated when interacted with to reduce visual clutter on both video walls and laptops. There are also improvements to how the keyboard focus is handled, making it easier to use both the virtual keyboard and physical keyboard.

Windows Tablet mode settings are now supported for devices with detachable keyboards.

Personal folders have been renamed "Codice folders".

Copy and paste

There is now support for limited copy and paste using CTRL-C/CTRL-V with a physical keyboard. You can also undo/redo text entered in input fields and there's improved text selection support. These changes improve the user experience on desktop and laptop machines.

New welcome screen and default canvas

There's a new welcome screen which improves the workspace state management.

Users can now also specify a default canvas for each client that is accessible from the welcome screen.

Users and access control

Canvus Connect server now supports users and groups and allows restricting access to canvases and folders. Canvus supports two authentication mechanisms: local passwords stored on the Canvus server itself and federated authentication using SAML 2.0. SAML support allows 3rd party Identity Providers such as Google, AD FS, Okta, LogMeIn, OneLogin, etc. to be used to sign-in to a Canvus server.

To avoid having to enter credentials on a video wall, Canvus also allows authentication using a mobile device by scanning a QR code on the video wall.

Users can also now send links to specific canvases that can be opened in the Canvus client without having to configure server details manually in the INI file.

With the introduction of proper access control, canvas passwords are no longer supported with shared canvases on a Canvus Connect server. They are still supported for local canvases. See the section in the manual for details of what happens in migration.

Server-wide REST API authentication tokens have been removed. They have been replaced by user-specific access tokens that users can manage in the web UI.

New web dashboard

The new web UI for Canvus Connect server allows users to manage access control of their canvases and maintain their personal access tokens for REST API.

The web UI also provides tools for Canvus Connect server administrators to manage user groups, configure server settings and manage their server license. It also provides administrators access to an audit event log which records users' actions on the server for auditing purposes.

For each canvas you have now the possibility to copy a canvas-link from the dashboard. Anybody who has a Canvus client on their laptop will automatically be guided to the correct canvas by clicking on that link. This is a very useful tool for making sure that everybody is connected to the same canvas for meetings.

Simplified Canvus Connect server configuration

The Canvus Connect server now requires a single port to be exposed to the outside world for clients to connect to it. By default it uses port 443 (HTTPS) and optionally redirects traffic from port 80 (HTTP). This simplifies the firewall configuration and server deployment.

The server also automatically creates self-signed SSL certificates unless users specify their own.

Persistent web browser sessions

Web browser sessions on each canvas now persist for each user. In practice, this means that web browsers are no longer in "incognito mode" and users don't need to constantly re-login to any web services they use.

If Canvus client is configured for single-user mode, all downloads from browsers are stored in the user's operating system's Downloads folder ([\~/Downloads/Canvus]{.title-ref}).

Additionally, the starting page and default search URL for web browsers can be configured in Canvus client. This can be useful if a customer does not want to use Google as their default search engine.

And more...

There are over 2400 changes in Canvus for this release. We mentioned some of the highlights above but the list is not exhaustive.

We have also updated the Canvus Client Manual, the Canvus Server Manual, and the REST API Documentation for Canvus 3.0.
