+v3.1.3 Release Notes - October 18, 2025
+=====================================
+
+
+Improvements and Fixes
+----------------------
+
+The commit 77db242af51f496a1529b66d3022efad286a5f2d removed `sampleconfig/msp` from the orderer docker image,
+and as a result orderers deployed with docker built from the image failed to run due to a mounting error.
+Fixed by explicitly adding the config files in commit bbd9ca7dcdc09f49bc60725a6095b1bb7c212a14.
+
+Dependencies
+------------
+Fabric v3.1.3 has been tested with the following dependencies:
+* Go 1.25.2
+* CouchDB v3.4.2
+
+Fabric docker images on docker.io and ghcr.io utilize Ubuntu 24.04.
+
