 TiUP Changelog
 
+## [1.8.0] 2021-12-06
+
+### New Features
+
+- Add `data-dir` support for TiCDC in `tiup-playground` ([#1631](https://github.com/pingcap/tiup/pull/1631), [@nexustar](https://github.com/nexustar))
+- Add support of using custom files as input of `edit-config`, and support dumping the current full config to a file with `show-config` command in `tiup-cluster` ([#1637](https://github.com/pingcap/tiup/pull/1637), [@haiboumich](https://github.com/haiboumich))
+- Add support of next-generation monitor (`ng-monitor`) in `tiup-playground` ([#1648](https://github.com/pingcap/tiup/pull/1648), [@nexustar](https://github.com/nexustar))
+- Add support of inserting custom `scrape_configs` to Prometheus configs in `tiup-cluster` ([#1641](https://github.com/pingcap/tiup/pull/1641), [@nexustar](https://github.com/nexustar))
+- [experimental] Support 2-staged scaling out for `tiup-cluster` ([#1638](https://github.com/pingcap/tiup/pull/1638) [#1642](https://github.com/pingcap/tiup/pull/1642), [@srstack](https://github.com/srstack))
+  - Scaling out of a TiDB cluster can be devided with `--stage1` and `--stage2` arguments, the stage 1 deploys files and configs but not starting the new instances, and the stage 2 actually starts the new instances and reload necessary configs
+  - This could be useful if you want to modify config of the new instances or use a custom binary with `patch` **before** the first start of the new instances
+- [experimental] Implement plain text output and support custom output writer for logs ([#1646](https://github.com/pingcap/tiup/pull/1646), [@AstroProfundis](https://github.com/AstroProfundis))
+
