+Issues resolved since last release
+----------------------------------
+N/A since this is the first release tag on OP-TEE.
+
+
+Known issues

+
+*   Issue(s) open on GitHub
+    *   [#95][pr95]: An error about building the test code of libtomcrypt.
+
+    *   [#149][pr149]: when testing optee os with arm trusted firmware (I
+	utilized optee os tee.bin as bl32 image) on juno platform, I got an
+        error.
+
+    *   [#161][pr161]: tee_svc_cryp.c lacks accessibility checks on
+        user-supplied TEE_Attributes.
