 # What's New with [Terraform Modules](https://github.e.it.census.gov/terraform-modules/)
 
+## 2026-03-19: [aws-common-security-groups//it-windows-base](https://github.e.it.census.gov/terraform-modules/aws-common-security-groups/tree/2.11.0/it-windows-base)
+
+This changes refactors the `it-windows-base` security group to use a YAML file (within the module) which sets up the appropriate 
+security group rules. This changes from using specific IP blocks to using Prefix Lists defined in the central network account, so that we may
+more easily adapt to IP changes for services.
+
+To apply first time, no changes neede to be made.  On an update (terraform init -upgrade), it will fail, as all of the rules are added not through
+dynamic blocks but through the security group rule resource.  We will have a script and instructions on how to proceed with this.
+
+* 2.11.0 -- 2026-03-19
+  - it-windows-base
+    - refactor to use prefix lists and a YAML file
+    - remove obsolete servicenow scan rules
+
 ## 2026-03-13: [aws-sso//policies/sc-readonly](https://github.e.it.census.gov/terraform-modules/aws-sso/tree/1.6.0/policies/sc-readonly)
 
 This change moves the `sc-readonly` permissionset into a module, so we can change in one place for all organizations.
