+
+### Community
+

+- All experiments have been turned on for Go nightly ([Issue 818](https://github.com/golang/vscode-go/issues/818)) <!-- CL 264317 --> <!-- CL 267678 -->
+
+### Enhancements
+
+- Added a snippet for TestMain ([Issue 629](https://github.com/golang/vscode-go/issues/629)) <!-- CL 254497 -->
+- Added `lispcase`, `pascalcase` and `keep` as transform variants for go.addTags ([Issue 906](https://github.com/golang/vscode-go/issues/906), [936](https://github.com/golang/vscode-go/issues/936)) <!-- CL 271357 -->
+- Added support for `gomodifytags`'s --template flag ([Issue 826](https://github.com/golang/vscode-go/issues/826)) <!-- CL 264299 -->
+- Language Server
+	* Upgraded to the latest vscode-languageclient pre-release ([Issue 42148](https://github.com/golang/go/issues/42148)) <!-- CL 266497 -->
+- Debugging
+	* package.json: activate extension onDebugInitialConfigurations ([Issue 131](https://github.com/golang/vscode-go/issues/131)) <!-- CL 267899 -->
+
+
+### Fixes
+
+- Fixed test streaming output handling to correctly add -json flag ([Issue 471](https://github.com/golang/vscode-go/issues/471)) <!-- CL 268839 -->
+- Fixed bug that unnecessarily buffered test output ([Issue 917](https://github.com/golang/vscode-go/issues/917)) <!-- CL 269917 -->
+- Fixed a bug that occurred when choosing a new Go environment using the file picker ([Issue 868](https://github.com/golang/vscode-go/issues/868), [864](https://github.com/golang/vscode-go/issues/864)) <!-- CL 267898 -->
+- Hide running test StatusBarItem after cancelling tests <!-- CL 268838 -->
+- Tool Installation
+	* Unset GOOS/GOARCH/GOROOT/... from tool installation env since the tools need to be built for the host machine ([Issue 628](https://github.com/golang/vscode-go/issues/628)) <!-- CL 264323 -->
+	* Changed the dependency tool installation to use the `go` command chosen from the current `GOROOT/bin` for gocode-gomode too ([Issue 757](https://github.com/golang/vscode-go/issues/757)) <!-- CL 264318 -->

+- Adjusted home directory used in gerrit CI since recent changes in kokoro were restricting access ([Issue 833](https://github.com/golang/vscode-go/issues/833)) <!-- CL 264877 -->
