+- The `Base.convert(IOStream, ::Message)` method has been deprecated due to

 ### Fixed
 - Fixed [`isfreed()`](@ref), which would previously return the wrong values

-High-level Message object for sending/receiving ZMQ messages in shared buffers.

+
+High-level `Message` object for sending/receiving ZMQ messages in shared
+buffers. As an `AbstractArray`, it supports common (non-resizeable) array
+behaviour.

+# Examples
+```jldoctest
+julia> using ZMQ
+
+julia> m = Message("foo")
+3-element Message:
+ 102
+ 111
+ 111
+
+julia> m[1]               # Array indexing
+102
+
+julia> m[end] = 103       # Array assignment
+103
+
+julia> unsafe_string(m)   # Conversion to string (only do this if you know the message is a string)
+"fog"
+
+julia> IOBuffer(m)        # Create a zero-copy IOBuffer
+IOBuffer(data=UInt8[...], readable=true, writable=false, seekable=true, append=false, size=3, maxsize=Inf, ptr=1, mark=-1)
