Backwards compatible way of closing mchains

[Marco Arena]

Hi!
I have just seen the new release and I have a small suggestion for the wiki.

Since abstract_message_chain_t::close(close_mode) is now deprecated, I would explicitly mention on the release notes (wiki) how to replace this call (and related ones) with the new one in order to get the very same behavior.

For example:

close_retain_content(chain);

is now equivalent to:

close_retain_content(so_5::exceptions_enabled, chain);

What do you think?

Hi!

I think you're right. I'll update the release notes later today.
