+## Unreleased
+### Changed
+- Most built-in logs like `Finished an outgoing client HTTP request` now use the context logger. 
+
+### Fixed
+- HTTP `DELETE` methods on clients can now send a JSON payload. Previously it was silently discarded. 
+
+## 1.0.2 - 2018-08-28 
+### Added
+- **Context logger**: Added [`ContextLogger`](https://godoc.org/github.com/uber/zanzibar/runtime#ContextLogger) interface. This new logger interface automatically has log fields for Zanzibar-defined per-request fields like `requestUUID` to allow correlating all log messages from a given request. [`WithLogFields`](https://godoc.org/github.com/uber/zanzibar/runtime#WithLogFields) method added to `runtime` package to allow users to add their own log fields to be used by subsequent logs that use the context. The context logger is added as a new field to [`DefaultDependencies`](https://godoc.org/github.com/uber/zanzibar/runtime#DefaultDependencies). 
+
+### Changed
+- Removed support for Go 1.9 and added support for Go 1.11. 
+- Some request fields like `endpointID` will no longer be present on messages using the default logger. 
+
+### Deprecated
+- The default logger (`DefaultDependencies.Logger`) is now deprecated along with multiple related functions and public variables. The preferred way to log is now using the context logger. 
+
+## 1.0.1 - 2018-08-21
+### Added
+- Upgraded thriftrw to v1.12.0 from v1.8.0. This adds, among other things, `Ptr()` helper methods and getters for some thriftrw-go defined structs. 
+
 ## 1.0.0 - 2018-08-17
 ### Added
 - Initial release.
