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
- Updated crash to 0.13.0 which includes following changes:
- Added `dynamic` as output format option
- Added ``--version`` to cli interface to show crash version and exit
- Display command help in case the command is not used correctly
- Display NULL values in mixed mode correctly

- Improved readability of sql syntax highlighting
- Attempting to use unknown command now results in an error
- Fix: return correct status for ``GET`` requests on ``/`` REST endpoint

immediately after a `DROP TABLE` statement to fail.
- Fixed a minor memory leak that occurred if custom schemas were deleted.
- Fixed incorrect comparison in query by IP type

services use the same stats probe per row; previously values derived from
these services could have been from different probes
