- Fixed output of some functions (e.g. `splitArgs`/`splitLines`) not working in
for loops (#1822, #1823 by @stawii).
- Added a new `TASK_OFFLINE` environment variable to configure the `--offline`
flag and expose it as a special variable in the templating system (#1470,
#1716 by @vmaerten and @pd93).
- Fixed a bug where multiple remote includes caused all prompts to display
without waiting for user input (#1832, #1833 by @vmaerten and @pd93).
- When using the

- Improved the error message when a dotenv file cannot be parsed (#1842 by
@pbitty).
- Fix issue with directory when using the remote experiment (#1757 by @pbitty).
- Fixed an issue where a special variable was used in combination with a dotenv
file (#1232, #1810 by @vmaerten).
- Refactor the way Task reads Taskfiles to improve readability (#1771 by
@pbitty).
- Added a new option to ensure variable is within the list of values (#1827 by
@vmaerten).
- Allow multiple prompts to be specified for a task (#1861, #1866 by @mfbmina).
- Added new template function: `numCPU`, which returns the number of logical
CPUs usable (#1890, #1887 by @Amoghrd).
- Fixed a bug where non-nil, empty dynamic variables are returned as an empty
interface (#1903, #1904 by @pd93).

## Git nodes

You can also include a Taskfile from a Git node. We currently support ssh-style and http / https addresses like `[email protected]/foo/bar.git//Taskfiles.yml?ref=v1` and `https://example.com/foo/bar.git//Taskfiles.yml?ref=v1`.

You need to follow this pattern : `<baseUrl>.git//<path>?ref=<ref>`.
The `ref` parameter, optional, can be a branch name or a tag, if not provided it'll pick up the default branch.
The `path` is the path to the Taskfile in the repository.

If you want to use the SSH protocol, you need to make sure that your ssh-agent has your private ssh keys added so that they can be used during authentication.

### Ensuring required variables have allowed values

If you want to ensure that a variable is set to one of a predefined set of valid values before executing a task, you can use requires.
This is particularly useful when there are strict requirements for what values a variable can take, and you want to provide clear feedback to the user when an invalid value is detected.

To use `requires`, you specify an array of allowed values in the vars sub-section under requires. Task will check if the variable is set to one of the allowed values.
If the variable does not match any of these values, the task will raise an error and stop execution.

This check applies both to user-defined variables and environment variables.

Example of using `requires`:

```yaml
version: '3'
tasks:
deploy:
cmds:
- echo "deploying to {{.ENV}}"
requires:
vars:
- name: ENV
enum: [dev, beta, prod]
```

If `ENV` is not one of 'dev', 'beta' or 'prod' an error will be raised.

:::note

This is supported only for string variables.

cmds:
- task: dangerous
dangerous:
prompt:
- This is a dangerous command... Do you want to continue?

Warning prompts are called before executing a task. If a prompt is denied Task
will exit with [exit code](/api#exit-codes) 205. If approved, Task will continue
as normal.
