+## [v1.39.4]

+### Fixes
+
+- Correct --no-color flag behaviour in non-tty environments
+The changes retain the default behaviour of showing colors in tty and no colors in non-tty if no flag is passed. However, on passing the --no-color=false, non-tty environments can also get colored output.[#1339](https://github.com/Kong/deck/pull/1339)
+- Add validation on `deck file patch` to avoid confusing behaviour. The command intends to patch input files either via selector-value flags or command arguments. The change ensures that at least one of these is present, but not both at the same time.[#1342](https://github.com/Kong/deck/pull/1342) 
+- Fix rendering for expression routes, keeping kong gateway version in consideration. [go-database-reconciler #118](https://github.com/Kong/go-database-reconciler/pull/118) [#1351](https://github.com/Kong/deck/pull/1351)
