 Bug Fixes:
 
+- Fix issue where setting test suite delimiter prevent execution of all tests. [#4092](https://github.com/microsoft/vscode-cmake-tools/issues/4092)
 - Fix our setting of `isUserPreset` for presets, only set it to `true` if it's defined in a user presets file. [#4059](https://github.com/microsoft/vscode-cmake-tools/issues/4059)
 - Fix issue where duplicate presets are being listed in dropdown. [#4104](https://github.com/microsoft/vscode-cmake-tools/issues/4104)
 - Ensure that tests are updated after a build. [#4148](https://github.com/microsoft/vscode-cmake-tools/pull/4148)
