crate 0.49.3/0.50.0 发布,其中 0.49.3 的更新内容如下:

  •  - Fixed an issue where ``_raw`` and ``_doc`` in primary key queries
       returned ``NULL``

     - Added `dynamic` as output format option

        - Display NULL values in mixed mode correctly
        - Fixed broken 'mixed' output style due to overriding import
        - Improved readability of sql syntax highlighting

  •  - Fixed incorrect comparison in query by IP type

  •  - Fix: make sure sys.nodes expressions that utilize os/process/network/jvm
