Changelog for Teamscale 7.7

Newer Release Available

Our current release is available here.

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 ./ &.

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 -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, 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

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.
