Release Announcement

Check out the Release Newsletter for Teamscale 7.8.

Changed backup behavior (since Teamscale 7.8)

Starting with Teamscale 7.8 automatic backups are enabled by default with sensible defaults. In addition, the default location of storing backups changed to a folder named backup relative to the process working directory.

Existing instances are not affected and previously configured settings will be restored upon backup import. In that case it is recommended to enable automated backups if not configured yet.

Java 17 Required (since Teamscale 7.7)

As of Teamscale 7.7, running the Teamscale server requires a Java Runtime Environment, Version 17 or later.

Changed startup on non-Docker Linux installations (since Teamscale 7.7)

As of Teamscale 7.7, Teamscale is no longer executed using nohup on non-Docker Linux installations. This requires manual intervention:

  • If you are using systemd to manage Teamscale as service, you have to change the startup type from Type=forking to Type=simple in the Teamscale systemd unit. Remember to reinstall the service.
  • For custom linux setups that depend on nohup, start Teamscale like: nohup ./teamscale.sh &.

In general, we strongly recommend running Teamscale on Linux with Docker.

Changed Teamscale systemd service type (since Teamscale 7.7)

As of Teamscale 7.7, the Teamscale systemd service type must be updated to type=simple, instead of the previous type=forking

Improved administration experience (since Teamscale 7.7)

Teamscale 7.7 features several changes that improve the default administration experience.

  • The default location of cloning remote Git (or SAP) repositories is a folder named repo relative to the process working directory. Existing instances are not affected and the location previously configured will be set upon backup import. The option has been moved to Admin / Global Settings / Git.
  • The following JVM arguments are now always specified and can be removed from JVM_EXTRA_ARGS in jvm.properties: -Djco.session_timeout=60 -XX:-OmitStackTraceInFastThrow -Dsvnkit.http.methods=Basic,Digest,Negotiate,NTLM
  • The Teamscale temporary directory is now configurable with the TEAMSCALE_TEMP environment variable. If you previously specified a custom temporary directory using -Djava.io.tmpdir=..., we recommend removing this JVM argument and using the environment variable instead. The directory may be relative to the process working directory and is created if it does not exist.
SAP Java Connector required for importing ABAP® code (since Teamscale 7.7)

As of Teamscale 7.7, exporting ABAP® code from SAP systems requires a manual installation of the SAP Java Connector (SAP JCo) 3.1 or later. For detailed information on the installation process, please refer to Installation of the SAP Java Connector (JCo).

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 (opens new window)

Re-Analysis when Upgrading
  • When updating from 7.8.x, drop-in.
  • When updating from 7.7.x or earlier, a full re-analysis via backup is required.
