+- Travis badge should only show master [cc102ab]
+
+## 1.4.0
+
+### Features
+- Make string pretty diff user configurable (#273) [eb112ce, 649b44d]
+
+### Fixes
+- Use httputil.DumpRequest to pretty-print unhandled requests (#278) [a4ff0fc, b7d1a52]

+- 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:
 
@@ -14,6 +67,8 @@ Improvements:
 - `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.

+# 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.

vendor/github.com/onsi/gomega/RELEASING.md

+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.
