= NEWS for Ruby 2.3.0
This document is a list of user visible feature changes made between
releases except for bug fixes.
Note that each entry is kept so brief that no reason behind or
reference information is supplied with. For a full list of changes
with all sufficient information, see the ChangeLog file.
== Changes since the 2.2.0 release
=== Language changes
=== Core classes updates (outstanding ones only)
=== Core classes compatibility issues (excluding feature bug fixes)
* Array
* Array#select!, Array#keep_if, Array#reject!, and Array#delete_if
no longer changes the receiver array instantly every time the
block is called. [Feature #10714]
* Array#flatten and Array#flatten! no longer try to call #to_ary
method on elements beyond the given level. [Bug #10748]
* IO
* IO#close doesn't raise when the IO object is closed. [Feature #10718]
=== Stdlib updates (outstanding ones only)
accept_nonblock supports "exception: false" This is analogous to functionality found in IO#read_nonblock and IO#wait_nonblock. Raising exceptions for common failures on non-blocking servers is expensive and makes $DEBUG too noisy.
