 - Remove support for CodeQL CLI versions older than 2.13.5. [#3371](https://github.com/github/vscode-codeql/pull/3371)
 - Add a timeout to downloading databases and the CodeQL CLI. These can be changed using the `codeQL.addingDatabases.downloadTimeout` and `codeQL.cli.downloadTimeout` settings respectively. [#3373](https://github.com/github/vscode-codeql/pull/3373)
+- Databases created from [CodeQL test cases](https://docs.github.com/en/code-security/codeql-cli/using-the-advanced-functionality-of-the-codeql-cli/testing-custom-queries) are now copied into a shared VS Code storage location. This avoids a bug where re-running test cases would fail if the test's database is already imported into the workspace. [#3433](https://github.com/github/vscode-codeql/pull/3433)
