+## v1.4.434 (2026-03-09)
+
+### PR [#2052](https://github.com/danielmiessler/Fabric/pull/2052) by [praxstack](https://github.com/praxstack) and [ksylvan](https://github.com/ksylvan): feat(bedrock): dynamic region fetching and AWS_PROFILE conflict fix
+
+- Added dynamic Bedrock region fetching from `botocore`'s `endpoints.json`, expanding support to 40+ regions instead of a hardcoded list of 6, with a static fallback on error.
+- Fixed `AWS_PROFILE` environment variable conflict that caused `'failed to get shared config profile'` errors for users who had `AWS_PROFILE` set for other tools (e.g., Terraform, AWS CLI) while using explicit access keys or static credentials.
+- Improved empty auth choice handling to gracefully skip the selection instead of throwing an error.
