### 3.2.0 / 2015-02-03
[Full Changelog](http://github.com/rspec/rspec-expectations/compare/v3.1.2...v3.2.0)
Enhancements:
* Add `block_arg` method to custom matcher API, which allows you to
access the block passed to a custom matcher, if there is one.
(Mike Dalton, #645)
* Provide more detail in failure message of `yield_control` matcher.
(Jon Rowe, #650)
* Add a shorthand syntax for `chain` in the matcher DSL which assigns values
for use elsewhere, for example `chain :and_smaller_than, :small_value`
creates an `attr_reader` for `small_value` (Tom Stuart, #644)
* Provide a more helpful deprecation message when using the `should` syntax.
(Elia Schito, #663)
* Provide more detail in the `have_attributes` matcher failure message.
(Jon Rowe, #668)
* Make the `have_attributes` matcher diffable.
(Jon Rowe, Alexey Fedorov, #668)
* Add `output(...).to_std(out|err)_from_any_process` as alternatives
to `output(...).to_std(out|err)`. The latter doesn't work when a sub
process writes to the named stream but is much faster.
(Alex Genco, #700)
* Improve compound matchers (created by `and` and `or`) so that diffs
are included in failures when one or more of their matchers
are diffable. (Alexey Fedorov, #713)
Bug Fixes:
* Avoid calling `private_methods` from the `be` predicate matcher on
the target object if the object publicly responds to the predicate
method. This avoids a possible error that can occur if the object
raises errors from `private_methods` (which can happen with celluloid
objects). (@chapmajs, #670)
* Make `yield_control` (with no modifier) default to
`at_least(:once)` rather than raising a confusing error
when multiple yields are encountered.
(Myron Marston, #675)
* Fix "instance variable @color not initialized" warning when using
rspec-expectations outside of an rspec-core context. (Myron Marston, #689)
* Fix `start_with` and `end_with` to work properly when checking a
string against an array of strings. (Myron Marston, #690)
* Don't use internally delegated matchers when generating descriptions
for examples without doc strings. (Myron Marston, #692)
