+v1.5.6-beta3 Release Notes - Jan 3, 2023
+===================================
+
+v1.5.6-beta3 is a beta release, providing updates for the following issues in the Fabric CA:
+
+- Builds native arm64 CA binaries for linux and darwin
+- Builds multi-platform CA docker images for arm64 and amd64 with `buildx`
+- Builds CA docker images FROM ubuntu:20.04 (avoid SIGSEGV errors encountered with dynamic builds on musl/alpine libc)
+- Adds debug information for a mysterious [idemix error message](https://github.com/hyperledger/fabric-ca/pull/339)
+- Bumps Go version to 1.18.9
+
+Dependencies
+------------
+
+Fabric CA v1.5.6 has been tested with the following dependencies:
+- Go 1.18.9
+- Ubuntu 20.04 (for Docker images)
+
+
+Changes, Known Issues, and Workarounds
+--------------------------------------
+
+None.
+
+Known Vulnerabilities
+---------------------
+- FABC-174 Commands can be manipulated to delete identities or affiliations
+
+  This vulnerability can be resolved in one of two ways:
+
+    1) Use HTTPS (TLS) so that the authorization header is not in clear text.
+
+    2) The token generation/authentication mechanism was improved to optionally prevent
+       token reuse. As of v1.4 a more secure token can be used by setting environment variable:
+
+  FABRIC_CA_SERVER_COMPATIBILITY_MODE_V1_3=false
+
+  However, it cannot be set to false until all clients have
+  been updated to generate the more secure token and tolerate
+  FABRIC_CA_SERVER_COMPATIBILITY_MODE_V1_3=false.
+  The Fabric CA client has been updated in v1.4 to generate the more secure token.
+  The Fabric SDKs will be updated by v2.0 timeframe to generate the more secure token,
+  at which time the default for Fabric CA server will change to:
+  FABRIC_CA_SERVER_COMPATIBILITY_MODE_V1_3=false
+
+Resolved Vulnerabilities
+------------------------
+None.
