bipush and sipush: They are pushing immediate/constant int instead of byte or short, as the values appear in the stack/locals (consistency with JDK-8322481)
ior, ixor, (long ones too)...: They are bitwise instead of "Boolean" operations. Still can mention ixor, ior will be used for boolean operations given how booleans are represented in the JVM.
ishr, lshr: might clarify to be "arithmetic" to contrast with iushr and lushr's "logical".
