# CodeQL for Visual Studio Code: Changelog

## [UNRELEASED]

- Ensure databases are unlocked when removing them from the workspace. This will ensure that after a database is removed from VS Code, queries can be run on it from the command line without restarting VS Code. Requires CodeQL CLI 2.4.1 or later. [#681](https://github.com/github/vscode-codeql/pull/681)
- Fix bug when removing databases where sometimes the source folder would not be removed from the workspace or the database files would not be removed from the workspace storage location. [#692](https://github.com/github/vscode-codeql/pull/692)
- Query results with no string representation will now be displayed with placeholder text in query results. Previously, they were omitted. [#694](https://github.com/github/vscode-codeql/pull/694)
- Add a label for the language of a database in the databases view. This will only take effect for new databases created with the CodeQL CLI v2.4.1 or later. [#697](https://github.com/github/vscode-codeql/pull/697)
- Add clearer error message when running a query using a missing or invalid qlpack. [#702](https://github.com/github/vscode-codeql/pull/702)
- Add clearer error message when trying to run a command from the query history view if no item in the history is selected. [#702](https://github.com/github/vscode-codeql/pull/702)
- Fix a bug where it is not possible to download some database archives. This fix specifically addresses large archives and archives whose central directories do not align with file headers. [#700](https://github.com/github/vscode-codeql/pull/700)
- Avoid error dialogs when QL test discovery or database cleanup encounters a missing directory. [#706](https://github.com/github/vscode-codeql/pull/706)
- Add descriptive text and a link in the results view. [#711](https://github.com/github/vscode-codeql/pull/711)
- Fix the _Set Label_ command in the query history view. [#710](https://github.com/github/vscode-codeql/pull/710)
- Add the _CodeQL: View AST_ directly to text editors of files in database archives. [#712](https://github.com/github/vscode-codeql/pull/712)

## 1.3.7 - 24 November 2020

- Editors opened by navigating from the results view are no longer opened in _preview mode_. Now they are opened as a persistent editor. [#630](https://github.com/github/vscode-codeql/pull/630)
- When comparing the results of a failed QL test run and the `.expected` file does not exist, an empty `.expected` file is created and compared against the `.actual` file. [#669](https://github.com/github/vscode-codeql/pull/669)
- Alter structure of the _Test Explorer_ tree. It now follows the structure of the filesystem instead of the QL Packs. [#624](https://github.com/github/vscode-codeql/pull/624)
