## Bugs fixed

The following bugs are fixed in this release.

> [!NOTE]
> **Note:** The build number in the table specifies the earliest version of the component that contains the fix. Use that build number to determine if you already have the fix installed, or if you need to perform an update. The apigee-service utility displays the build number of the currently installed component:
>
> ```
> /opt/apigee/apigee-service/bin/apigee-service comp version
> ```
>
> where ***comp*** is the name of the component without the build number
> extension. For example:
>
> ```
> /opt/apigee/apigee-service/bin/apigee-service apigee-setup version
> ```
>
> or get the build number of all components:
>
> ```
> /opt/apigee/apigee-service/bin/apigee-all version
> ```
