### 2.11.2 / 2012-07-25
[full changelog](http://github.com/rspec/rspec-expectations/compare/v2.11.1...v2.11.2)
Bug fixes
* Define `should` and `should_not` on `Object` rather than `BasicObject`
on MacRuby. On MacRuby, `BasicObject` is defined but is not the root
of the object hierarchy. (Gabriel Gilder)
### 2.11.1 / 2012-07-08
[full changelog](http://github.com/rspec/rspec-expectations/compare/v2.11.0...v2.11.1)
Bug fixes
* Constrain `actual` in `be_within` matcher to values that respond to `-` instead
of requiring a specific type.
* `Time`, for example, is a legit alternative.
### 2.11.0 / 2012-07-07
[full changelog](http://github.com/rspec/rspec-expectations/compare/v2.10.0...v2.11.0)
Enhancements
* Expand `expect` syntax so that it supports expections on bare values
in addition to blocks (Myron Marston).
* Add configuration options to control available expectation syntaxes
(Myron Marston):
* `RSpec.configuration.expect_with(:rspec) { |c| c.syntax = :expect }`
* `RSpec.configuration.expect_with(:rspec) { |c| c.syntax = :should }`
* `RSpec.configuration.expect_with(:rspec) { |c| c.syntax = [:should, :expect] }`
* `RSpec.configuration.add_should_and_should_not_to Delegator`
Bug fixes
* Allow only `Numeric` values to be the "actual" in the `be_within` matcher.
This prevents confusing error messages. (Su Zhang @zhangsu)
* Define `should` and `should_not` on `BasicObject` rather than `Kernel`
on 1.9. This makes `should` and `should_not` work properly with
`BasicObject`-subclassed proxy objects like `Delegator`. (Myron
Marston)
### 2.9.1 / 2012-04-03
[full changelog](http://github.com/rspec/rspec-expectations/compare/v2.9.0...2.9.1)
Bug fixes
* Provide a helpful message if the diff between two objects is empty.
* Fix bug diffing single strings with multiline strings.
* Fix for error with using custom matchers inside other custom matchers
(mirasrael)
* Fix using execution context methods in nested DSL matchers (mirasrael)
### 2.9.0 / 2012-03-17
[full changelog](http://github.com/rspec/rspec-expectations/compare/v2.8.0...v2.9.0)
Enhancements
* Move built-in matcher classes to RSpec::Matchers::BuiltIn to reduce pollution
of RSpec::Matchers (which is included in every example).
* Autoload files with matcher classes to improve load time.
Bug fixes
* Align respond_to? and method_missing in DSL-defined matchers.
* Clear out user-defined instance variables between invocations of DSL-defined
matchers.
* Dup the instance of a DSL generated matcher so its state is not changed by
subsequent invocations.
* Treat expected args consistently across positive and negative expectations
(thanks to Ralf Kistner for the heads up)
