||
| ## Change | ||
|
|
||
| - The added property name can not be the same as an existing or deleted property name, otherwise, the operation of adding a property fails. [#5130](https://github.com/vesoft-inc/nebula/pull/5130) | ||
| - Limit the type conversion when modifying the schema. [#5098](https://github.com/vesoft-inc/nebula/pull/5098) | ||
| - The default value must be specified when creating a property of type `NOT NULL`. [#5105](https://github.com/vesoft-inc/nebula/pull/5105) | ||
| - Add the multithreaded query parameter `query_concurrently` to the configuration file with a default value of `true`. [#5119](https://github.com/vesoft-inc/nebula/pull/5119) | ||
| - Remove the parameter `kv_separation` of the KV separation storage function from the configuration file, which is turned off by default. [#5119](https://github.com/vesoft-inc/nebula/pull/5119) | ||
| - Modify the default value of `local_config` in the configuration file to `true`. [#5119](https://github.com/vesoft-inc/nebula/pull/5119) | ||
| - Consistent use of `v.tag.property` to get property values, because it is necessary to specify the Tag. Using `v.property` to access the property of a Tag on `v` was incorrectly allowed in the previous version. [#5230](https://github.com/vesoft-inc/nebula/pull/5230) | ||
| - Remove the column `HTTP port` from the command `SHOW HOSTS`. [#5056](https://github.com/vesoft-inc/nebula/pull/5056) | ||
| - Disable the queries of the form `OPTIONAL MATCH <pattern> WHERE <condition>`. [#5273](https://github.com/vesoft-inc/nebula/pull/5273) | ||
| - Disable TOSS. [#5119](https://github.com/vesoft-inc/nebula/pull/5119) | ||
