Changelog for Teamscale 9.1

New Features in This Release

To learn more about the new features introduced in Teamscale 9.1, please refer to the Release Newsletter for Teamscale 9.1.

Deprecated feature: Issue id parameter in Test Gap Treemap widgets

The "issue id" parameter of the Test Gap Treemap widget is deprecated and will be removed in Teamscale 9.1. Please use the Test Gaps > Issues perspective instead.

Added parameter support for abapLint checks as of version 8.9

Analysis profiles which specify an abapLint configuration file need to be manually migrated. This can be done by importing the abapLint configuration file via the Analysis Profiles view. The import will create a Teamscale analysis profile with the settings from the imported abapLint configuration file.

Action Required: Updated default CORS configuration as of version 8.9

The default configuration was changed to not allow any CORS requests. If you are using the Azure DevOps Integration or integrate Teamscale dashboards within other websites (e.g. Jira), you have to manually change the CORS configuration. Please refer to Configuring CORS Settings for more information.

Removed support for Istanbul and CQSE JS Profiler as of version 8.8

The support for Istanbul and CQSE JS Profiler were removed from Teamscale as of version 8.8. You can use the new Teamscale Javascript Profiler instead.

Removed feature in the Eclipse Plugin: "Show Test Coverage"

The 'Show Test Coverage' feature was removed for the Eclipse Plugin as of version 8.7.

Clang Tidy: Updated to Version 15 as of version 8.6

Non-docker installation using the Clang Tidy integration must update their Clang Tidy installation to version 15.

Removed feature: "Desktop Notification"

The 'Desktop Notification' feature was removed from Teamscale as of version 8.6.
