## Unreleased
|
||||
|
||||
- Allow to override Task colors using environment variables:
|
||||
`TASK_COLOR_RESET`, `TASK_COLOR_BLUE`, `TASK_COLOR_GREEN`,
|
||||
`TASK_COLOR_CYAN`, `TASK_COLOR_YELLOW`, `TASK_COLOR_MAGENTA`
|
||||
and `TASK_COLOR_RED`
|
||||
([#568](https://github.com/go-task/task/pull/568), [#792](https://github.com/go-task/task/pull/792)).
|
||||
- Fixed bug when using the `output: group` mode where STDOUT and STDERR were
|
||||
being print in separated blocks instead of in the right order
|
||||
([#779](https://github.com/go-task/task/issues/779)).
