+# SweRV RISC-V Core<sup>TM</sup> 1.1.1 from Western Digital
+## Release Notes
+1. SWERV core RISCV compatibility improvements
+    * The ebreak and ecall instructions are no longer counted in the MINSRET
+	  control and status register.
+    * Write to SBDATA0 does not start an SB write access when
+	  sbreadonaddr/dbreadondata is set.
