+## HEAD
+
+### Features
+- Make string pretty diff user configurable (#273) [eb112ce, 649b44d]
+
+### Fixes
+- Use httputil.DumpRequest to pretty-print unhandled requests (#278) [a4ff0fc, b7d1a52]
+- fix typo floa32 > float32 (#272) [041ae3b, 6e33911]
+- Fix link to documentation on adding your own matchers (#270) [bb2c830, fcebc62]
+- Use setters and getters to avoid race condition (#262) [13057c3, a9c79f1]
+- Avoid sending a signal if the process is not alive (#259) [b8043e5, 4fc1762]
+- Improve message from AssignableToTypeOf when expected value is nil (#281) [9c1fb20]
+
+## 1.3.0
+
+Improvements:
+
+- The `Equal` matcher matches byte slices more performantly.
+- Improved how `MatchError` matches error strings.
+- `MatchXML` ignores the order of xml node attributes.
+- Improve support for XUnit style golang tests. ([#254](https://github.com/onsi/gomega/issues/254))
+
+Bug Fixes:
+
+- Diff generation now handles multi-byte sequences correctly.
+- Multiple goroutines can now call `gexec.Build` concurrently.
+
+## 1.2.0
+
+Improvements:
+
+- Added `BeSent` which attempts to send a value down a channel and fails if the attempt blocks. 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. Instead of having `Match` return failure messages, two new methods `FailureMessage` and `NegatedFailureMessage` are called instead.
+- Moved and renamed OmegaFailHandler to types.GomegaFailHandler and OmegaMatcher to types.GomegaMatcher. Any references to OmegaMatcher in any custom matchers will need to be changed to point to types.GomegaMatcher
+
+New Test-Support Features:
+
+- `ghttp`: supports testing http clients
+ - Provides a flexible fake http server
+ - Provides a collection of chainable http handlers that perform assertions.
+- `gbytes`: supports making ordered assertions against streams of data
+ - Provides a `gbytes.Buffer`
+ - Provides a `Say` matcher to perform ordered assertions against output data
+- `gexec`: supports testing external processes
+ - Provides support for building Go binaries
+ - Wraps and starts `exec.Cmd` commands
+ - Makes it easy to assert against stdout and stderr
+ - Makes it easy to send signals and wait for processes to exit
+ - Provides an `Exit` matcher to assert against exit code.
+
+DSL Changes:
+
+- `Eventually` and `Consistently` can accept `time.Duration` interval and polling inputs.
+- The default timeouts for `Eventually` and `Consistently` are now configurable.
+
+New Matchers:
+
+- `ConsistOf`: order-independent assertion against the elements of an array/slice or keys of a map.
+- `BeTemporally`: like `BeNumerically` but for `time.Time`
+- `HaveKeyWithValue`: asserts a map has a given key with the given value.
+
+Updated Matchers:
+
+- `Receive` matcher can take a matcher as an argument and passes only if the channel under test receives an objet that satisfies the passed-in matcher.
+- Matchers that implement `MatchMayChangeInTheFuture(actual interface{}) bool` can inform `Eventually` and/or `Consistently` when a match has no chance of changing status in the future. For example, `Receive` returns `false` when a channel is closed.
+
+Misc:
+
+- Start using semantic versioning
+- Start maintaining changelog
+
+Major refactor:
+
+- Pull out Gomega's internal to `internal`

+# Contributing to Gomega
+
+Your contributions to Gomega are essential for its long-term maintenance and improvement. To make a contribution:
+
+- Please **open an issue first** - describe what problem you are trying to solve and give the community a forum for input and feedback ahead of investing time in writing code!
+- Ensure adequate test coverage:
+ - Make sure to add appropriate unit tests
+ - Please run all tests locally (`ginkgo -r -p`) and make sure they go green before submitting the PR
+ - Please run following linter locally `go vet ./...` and make sure output does not contain any warnings
+- Update the documentation. In addition to standard `godoc` comments Gomega has extensive documentation on the `gh-pages` branch. If relevant, please submit a docs PR to that branch alongside your code PR.
+
+If you're a committer, check out RELEASING.md to learn how to cut a release.
+
+Thanks for supporting Gomega!

+A Gomega release is a tagged sha and a GitHub release. To cut a release:
+
+1. Ensure CHANGELOG.md is up to date.
+ - Use `git log --pretty=format:'- %s [%h]' HEAD...vX.X.X` to list all the commits since the last release
+ - Categorize the changes into
+ - Breaking Changes (requires a major version)
+ - New Features (minor version)
+ - Fixes (fix version)
+ - Maintenance (which in general should not be mentioned in `CHANGELOG.md` as they have no user impact)
+2. Update GOMEGA_VERSION in `gomega_dsl.go`
+3. Push a commit with the version number as the commit message (e.g. `v1.3.0`)
+4. Create a new [GitHub release](https://help.github.com/articles/creating-releases/) with the version number as the tag (e.g. `v1.3.0`). List the key changes in the release notes.
