[erlang-questions] OTP R16A has been released

Been reading the README and I'm pretty excited for a lot of the changes
there. Especially anything related to contention and better parallel
behaviour for ETS tables, processes, ports, and module loading. I'll be
interested to see how well a stable version does for us in production.

Unicode support is nice. There is no mention of Unicode support
libraries. Anything regarding that? Did you get the libraries to add
unicode support through some random detection, purely switching on the
comment and using the right io functions?

Also:
  
  OTP-10739  Add search to Erlang shell's history. Thanks to Fred
   Herbert.

My name is Hebert :)

Here's a question regarding reltool updates:

     -- The rel specification now dictates the order in which
     included and used applications (specified in the .app file as
     included_applications and applications respectively) are
     loaded/started by the boot file. If the applications are not
     specified in the rel spec, then the order from the .app file
     is used. This was a bug earlier reported on systools, and is
     now also implemented in reltool. 

Does this let people put in orders that break the load/boot sequence
(say starting my app before stdlib/kernel, or other ones), or does it
only allow to specify ambiguous cases (where it doesn't contradict the
.app file)?

Thanks for all the work!
Fred.
