+\S{cl-2.11.05} Version 2.11.05
+
+\b Add \c{--v} as an alias for \c{-v} (see \k{opt-v}), for
+command-line compatibility with Yasm.
+
+\b Fix a bug introduced in 2.11.03 whereby certain instructions would
+contain multiple REX prefixes, and thus be corrupt.
+
+\S{cl-2.11.04} Version 2.11.04
+
+\b Removed an invalid error checking code. Sometimes a memref only with
+a displacement can also set an evex flag. For example:
+
+\c vmovdqu32 [0xabcd]{k1}, zmm0
+
+\b Fixed a bug in disassembler that EVEX.L'L vector length was not matched
+when EVEX.b was set because it was simply considered as EVEC.RC.
+Separated EVEX.L'L case from EVEX.RC which is ignored in matching.
+
+\S{cl-2.11.03} Version 2.11.03
+
+\b Fix a bug there REX prefixes were missing on instructions inside a
+\c{TIMES} statement.
+
\S{cl-2.11.02} Version 2.11.02
