Can be paired with `Eventually` to safely send a value down a channel with a timeout. +- `Ω`, `Expect`, `Eventually`, and `Consistently` now immediately `panic` if there is no registered fail handler. This is always a mistake that can hide failing tests. +- `Receive()` no longer errors when passed a closed channel, it's perfectly fine to attempt to read from a closed channel so Ω(c).Should(Receive()) always fails and Ω(c).ShoudlNot(Receive()) always passes with a closed channel. +- Added `HavePrefix` and `HaveSuffix` matchers. +- `ghttp` can now handle concurrent requests. +- Added `Succeed` which allows one to write `Ω(MyFunction()).Should(Succeed())`. +- Improved `ghttp`'s behavior around failing assertions and panics: + - If a registered handler makes a failing assertion `ghttp` will return `500`. + - If a registered handler panics, `ghttp` will return `500` *and* fail the test. This is new behavior that may cause existing code to break. This code is almost certainly incorrect and creating a false positive. +- `ghttp` servers can take an `io.Writer`. `ghttp` will write a line to the writer when each request arrives. +- Added `WithTransform` matcher to allow munging input data before feeding into the relevant matcher +- Added boolean `And`, `Or`, and `Not` matchers to allow creating composite matchers +- Added `gbytes.TimeoutCloser`, `gbytes.TimeoutReader`, and `gbytes.TimeoutWriter` - these are convenience wrappers that timeout if the underlying Closer/Reader/Writer does not return within the alloted time. +- Added `gbytes.BufferReader` - this constructs a `gbytes.Buffer` that asynchronously reads the passed-in `io.Reader` into its buffer. + +Bug Fixes: +- gexec: `session.Wait` now uses `EventuallyWithOffset` to get the right line number in the failure. +- `ContainElement` no longer bails if a passed-in matcher errors. + +## 1.0 (8/2/2014) + +No changes. Dropping "beta" from the version number. + +## 1.0.0-beta (7/8/2014) +Breaking Changes: + +- Changed OmegaMatcher interface.
