Changelog for Teamscale 7.4

Newer Release Available

Our current release is available here.

Urgent Security Notice: Teamscale affected by log4shell (CVE-2021-44228)

Teamscale is affected by the widely discussed log4shell (CVE-2021-44228) security vulnerability and its follow-up CVE-2021-45046. A third vulnerability in log4j has been published CVE-2021-45105, but Teamscale is not affected in its default installation. Another log4j vulnerability has been published CVE-2021-44832, which only affects Teamscale if the log4j configuration file can be changed by a third party.

Please update Teamscale to a version released on or after the 4th of January 2022.

Note: The Eclipse/IntelliJ/NetBeans plug-ins are also affected by the security vulnerability. Please make sure to update your plug-ins to the latest versions compatible with your currently deployed Teamscale version.

SNI Hostname Verification (since Teamscale 7.4)

As of Teamscale 7.4, the internal Jetty web server executes SNI hostname verification by default. If you encounter an error "Invalid SNI" when accessing Teamscale, please contact our support

REST XML Interface Removed (since Teamscale 7.0)

As of Teamscale 7.0, its REST XML interface (deprecated since Teamscale v6.0) has finally been removed. This affects only the legacy REST API; the new, versioned API is not affected. You have hence two options:

  • The preferred long-term solution is to migrate to the new, versioned REST API, i.e., to use REST endpoints like …/api/v7.0.0/….
  • A temporary solution is to keep using the legacy REST API but always send an Accept: application/json request header and accept JSON rather than XML responses. Note, however, that the legacy REST API will be deprecated and subsequently removed, too.
Changed Voting Behaviour for Bitbucket Server Integration (since Teamscale 6.7)

As of Teamscale 6.7, the Enable Voting option in the Bitbucket Server connector will only add the findings badge to the pull request description. Please enable the Enable pull request review option, if you want Teamscale to also review pull requests.

Changed Permissions when Using Docker Image (since Teamscale 6.3)

As of Teamscale 6.3, Teamscale is no longer executed as the root user in the Docker container, but as user teamscale (UID=1000). Please make sure to either allow this user to access the mounted directories and files or add a user mapping to your docker-compose file, e.g. user: technical-user, which refers to a user whose permissions should be mapped to teamscale.

Java 11 Required (since Teamscale 6.2)

As of Teamscale 6.2, running the Teamscale server requires a Java Runtime Environment, Version 11 or later.

Changed Resolving of Configuration Files (since Teamscale 6.0)
  • As of Teamscale 6.0, all configuration files are loaded using the same logic. In particular configuration files in the process working directory take precedence over ones in the Teamscale installation.
  • Relative paths specified in configuration files will always be resolved to the working directory. The working directory usually equals the installation directory unless explicitly changed.
  • Custom check JAR files can be deployed in a directory relative to the working directory and installation directory.
  • Searching for a Teamscale configuration file in the installation root directory. Use the file in one of the config directories.
  • Searching for a license in the installation root directory, or a directory specified by the Java system property teamscale.license.path is no longer supported. Use the environment variable TEAMSCALE_CONFIG to specify a separate configuration directory or pass the license using the TS_LICENSE environment variable if you cannot place the license in one of the config directories.
  • The administrative service to read and write configuration files via the Web API (config-files) has been removed.
Re-Analysis when Upgrading
  • When updating from 7.4.x, drop-in.
  • When updating from 7.3.x or earlier, a full re-analysis via backup is required.
