Overview

This page lists new features and bug fixes for Code42 app version 8.2.

For the Code42 cloud and administration console, see Code42 cloud release notes.

Code42 app version 8.2.2

In cloud-only Code42 environments, user devices will be automatically upgraded to Code42 version 8.2.2 over several days, beginning August 4, 2020. Administrators can delay this upgrade by up to 60 days by configuring a global delay or organization exception.

Bug fixes

Fixed a rare security event reporting issue for Windows devices using the Chrome web browser.
Fixed two issues introduced in Code42 app version 8.2.0:
- Devices upgrading to the Code42 cloud from an on-premises environment could be deauthorized after the upgrade.
- Linux devices returned to always using the CPU usage setting specified for When user is away. In version 8.2.0, the When user is present setting was used instead.

Code42 app version 8.2.0

In cloud-only Code42 environments, user devices will be automatically upgraded to Code42 version 8.2.0 over several days, beginning July 15, 2020. Administrators can delay this upgrade by up to 60 days by configuring a global delay or organization exception.

Features

Application, file paths, and service name changes to "Code42"

Code42 app version 8.2.0 changes some instances of "CrashPlan" to "Code42" in the name of the application, service, and related file paths. See Code42 agent version 8.2.0 changes to application and service names for the complete list of changes.

If your Code42 environment uses any of the following, you may need to update your configurations to ensure compatibility with Code42 app version 8.2.0 and later:

Firewall rules, if based on the CrashPlanService name. (Firewall rules based on IP addresses are not affected.)
Application monitoring with device management tools like SCCM or Jamf to ensure the Code42 process is always running.
Code42 exceptions for antivirus, malware, or other security monitoring tools.
Automated or scripted deployment and installation processes that include the filename of the .msi, .dmg, or .tgz Code42 installer.

More optimizations to reduce CPU usage

Building on improvements introduced in Code42 app version 8.0.0, version 8.2.0 continues to reduce CPU usage and to optimize resource consumption on Windows, Mac, and Linux devices. Specific enhancements include:

Improved application of existing CPU limit settings and better management of CPU resources.
Security monitoring processes now always adhere to CPU limits. (Previously, you had the choice to apply limits only to backup processes.)
Fixed an issue in which the Code42 app could use unexpectedly high amounts of CPU if no files are selected for backup.

Other enhancements and updates

Security updates.
On Mac and Linux devices, the Code42 app installer can now also be used to upgrade to a newer version. This enables you to use the same device management process for upgrades and new installations. Previously, Mac and Linux devices required separate files for upgrades and new installations. (The Windows Code42 app installer already supports both upgrades and new installations with the same installer package.)
Adds support for Ubuntu 20.04 on Linux devices.
On Linux devices, the Code42 app no longer adds an icon to the desktop.
In the Code42 federal environment, adds support within the Code42 app for backing up and transferring Windows user profile data with Microsoft's User State Migration Tool (USMT).
Removes support for YARA/pattern matching detection. (The option to enable pattern matching was removed from the Code42 console in January, 2020, but devices with pattern matching enabled before that continued to report results until now.)

Bug fixes

General

Performance and stability improvements to both security and backup processes.
Improvements to logging.

Exfiltration detection

The following bug fixes improve exfiltration detection and security reporting. While these fixes are included in Code42 app version 8.2.0, they primarily benefit administrator viewers of the Code42 console.

Fixed a rare issue in which security events for files with an unknown size could report a negative size value. Now, unknown size values are left blank.
Fixed an issue on Linux devices in which removable media file activity was not detected on volumes that are password protected or mounted via Device Mapper.
Fixed a rare issue on Mac devices in which file activity could be incorrectly reported as syncing to iCloud for files that were not actually synced by the user.
Fixed an issue on Mac and Linux devices in which file events were not detected for deleted files under specific circumstances.

Backup and restore

Fixed an issue in which changing the Removed deleted files setting to Never did not save save properly in some cases.

User interface and display

Improved messaging in the Code42 app when a connection to the Code42 cloud is unavailable. Previously, a dropped connection could result in a misleading message stating, "The destination doesn't recognize your device." Now, the message more correctly states, "Unable to connect" with an option to retry.

Installation and deployment

Fixed a rare issue in which some devices experienced an unexpected delay before automatically upgrading to a new Code42 app version.
Fixed an issue introduced in Code42 app version 8.0 which prevented users from signing in on devices running Windows 7.
Fixed a rare compatibility issue between Code42 app authentication and certain third-party SAML 2.0 identity providers (IdPs).
Fixed a rare issue introduced in Code42 app version 8.0 in which some users received an "Unknown error" message while attempting to sign in to the Code42 app.

Known issues

In some circumstances, users may be prompted to sign in to the app the next time they open it after upgrading to Code42 app version 8.2.0. Background processes for security monitoring and backup continue without interruption; sign-in is only required to view the user interface.
On Mac devices, since the application name changed from Code42 CrashPlan to Code42, if you pinned the Code42 app in the Dock, you must manually remove the old icon and re-pin the new one.
For Mac devices upgrading to Code42 version 8.2.0 from unsupported version 4.8, attempting to open the Code42 app from Applications may display an error message. To open the app, use Launchpad or the Code42 menu bar app instead. Alternatively, restart the device.
The Code42 app does not launch on devices running Red Hat Enterprise Linux (RHEL) version 7 when installed with user permissions (instead of root). To launch the Code42 app, you must either:
- Perform the installation as an elevated user, or
- Manually change the file permissions of /home/<user>/crashplan/electron/chrome-sandbox to be owned by root and to allow read, write, and execute access (4755). For example:

sudo chown root:root /home/<user>/crashplan/electron/chrome-sandbox
sudo chmod 4755 /home/<user>/crashplan/electron/chrome-sandbox
