This release includes the following enhancements:

• Increased limits for policy components: Policy components were previously configured as attributes of the policy. The new version refactors policy components as separate objects with their own names. This allows for a large increase in the number of components you can have in each associated policy, and the ability to move components between lists within the policy. See Policy Components for more information.
• Higher bandwidth for firewalls on demand: You can request an increase from 4Gbps to 25Gbps by opening a support request.
• Regional High Availability: Choose whether to deploy your firewalls regionally or to a specific availability domain to optimize performance. See Overview of Network Firewall for more information.
• Operational improvements: Updating a firewall no longer causes a connection reset.
• Bulk import policy components: You can now bulk import policy components using a .json file. You can import the maximum allowed components in one file. The Network Firewall service provides a .json template for each component type that you can download and use to construct an import file. See Bulk Importing Policy Components for more information.
• Easily reorder security and decryption rules: When you create or edit a rule, you can specify its position of the rule in relation to other rules in the policy. You can reorder rules during creation, when editing a rule, or you can reorder rules within the list shown in the policy details page. See Creating a Decryption Rule and Creating a Security Rule for more information.
• Search for components: Because components are now independent objects, you can use the Search function to find them by name. See Overview of Search for more information.
• Easy migration: Use the provided upgrade workflow to quickly and easily upgrade your policies to the new version. When you upgrade your policies, any associated firewalls are also upgraded. See Upgrading a Policy for more information and instructions.
• For general service information, see the Network Firewall Home Page.
