crate 0.49.4 发布，更新内容如下：
-
- Fixed issue that could lead to deadlock and therefore freezing of a node when there where too many queries asking for routing information in parallel.
-
- Fix: Querying from information_schema while a table is created could cause an error
-
- only log amazon s3 client stuff on level ``WARN``
-
- log failing uri on COPY FROM
-
- Fixed a NPE that was thrown if a SELECT statement contained `_score` in the result columns and an ORDER BY clause.
-
- Fix: selecting error from sys.jobs_log caused a NPE in some cases
-
- Fix: If a query would fail because a shard starts to relocate during query time, the query is retried now
-
- Fix: load Crate plugins only once on node start
-
- Fixed an issue that caused `sys.shards` queries to omit unassigned shards if the query was made against a node that has `node.data` set to false
-
- Fix: Fixed a bug where some searchers were not properly closed
-
- Fixed a race condition that could cause `DROP TABLE IF EXISTS` to fail if the table was concurrently dropped.
-
- Fixed a race condition in `ALTER TABLE <partitioned_table>` that could occur if a `DELETE FROM <partitioned_table>` was invoked immediately before the `ALTER TABLE` statement.
