New features
Vulnerabilities of middleware are fixed, and the middleware and connection security is improved.
Update methods
You can update your bastion host in custom or automatic mode. During the available update period for the region of your bastion host, you can specify a custom period to update your bastion host or wait until your bastion host is automatically updated.
- Custom mode
You can specify a custom period during which you want to update your bastion host. The period must be within the available update period for the region of your bastion host. For more formation, see Available update periods and Update a bastion host.
- Automatic mode
Your bastion host is automatically updated when a default period starts. For more information about the default periods for different regions, see Available update periods. If you do not specify a custom period for an update, your bastion host is automatically updated during a default period.
- If you choose the automatic mode, your bastion host is updated during a default period.
Bastionhost randomly determines the default period based on the available update period for the region of your bastion host.
If you want to update your bastion host during a custom period, we recommend that you specify the custom period at the beginning of the available update period for the region of your bastion host. If you do not specify the custom period at the beginning of the available update period, your bastion host may be automatically updated when a default period starts.
- The default period may overlap with the peak hours of your business. This may affect your business. To prevent business interruptions, we recommend that you specify a custom period during which the impact of an update is minimized.
Impact
- If your bastion host is being updated, it is in the Updating Configuration state, and your business may be interrupted for a few seconds. We recommend that you specify a custom period to update your bastion host in the off-peak hours of your business.
- Transport Layer Security (TLS) versions that are supported by Bastionhost are updated. You can access Bastionhost by using only browsers that use TLS 1.2 or later. We recommend that you update the TLS version of your browser. Alternatively, you can use another browser that uses a TLS version supported by Bastionhost.

The available update periods vary based on the region of your bastion host. The following table lists available update periods for specific regions.
