 # Changelog
 
+## v3.14.0 - 2022-07-08
+
+- Add ability to override the `.task` directory location with the
+  `TASK_TEMP_DIR` environment variable.
+- 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)).
+- Starting on this release, ARM architecture binaries are been released to Snap
+  as well
+  ([#795](https://github.com/go-task/task/issues/795)).
+- i386 binaries won't be available anymore on Snap because Ubuntu removed the support
+  for this architecture.
+- Upgrade mvdan.cc/sh, which fixes a bug with associative arrays
+  ([#785](https://github.com/go-task/task/issues/785), [mvdan/sh#884](https://github.com/mvdan/sh/issues/884), [mvdan/sh#893](https://github.com/mvdan/sh/pull/893)).
+
+## v3.13.0 - 2022-06-13
+
+- Added `-n` as an alias to `--dry`
+  ([#776](https://github.com/go-task/task/issues/776), [#777](https://github.com/go-task/task/pull/777)).
+- Fix behavior of interrupt (SIGINT, SIGTERM) signals. Task will now give time
+  for the processes running to do cleanup work
+  ([#458](https://github.com/go-task/task/issues/458), [#479](https://github.com/go-task/task/pull/479), [#728](https://github.com/go-task/task/issues/728), [#769](https://github.com/go-task/task/pull/769)).
+- Add new `--exit-code` (`-x`) flag that will pass-through the exit form the
+  command being ran
+  ([#755](https://github.com/go-task/task/pull/755)).
+
+## v3.12.1 - 2022-05-10
+
+- Fixed bug where, on Windows, variables were ending with `\r` because we were
+  only removing the final `\n` but not `\r\n`
+  ([#717](https://github.com/go-task/task/issues/717)).
+
+## v3.12.0 - 2022-03-31
+
+- The `--list` and `--list-all` flags can now be combined with the `--silent`
+  flag to print the task names only, without their description
+  ([#691](https://github.com/go-task/task/pull/691)).
+- Added support for multi-level inclusion of Taskfiles. This means that
+  included Taskfiles can also include other Taskfiles. Before this was limited
+  to one level
+  ([#390](https://github.com/go-task/task/issues/390), [#623](https://github.com/go-task/task/discussions/623), [#656](https://github.com/go-task/task/pull/656)).
+- Add ability to specify vars when including a Taskfile.
+  [Check out the documentation](https://taskfile.dev/#/usage?id=vars-of-included-taskfiles)
+  for more information.
+  ([#677](https://github.com/go-task/task/pull/677)).
+
+## v3.11.0 - 2022-02-19
+
+- Task now supports printing begin and end messages when using the `group`
+  output mode, useful for grouping tasks in CI systems.
+  [Check out the documentation](http://taskfile.dev/#/usage?id=output-syntax) for more information
+  ([#647](https://github.com/go-task/task/issues/647), [#651](https://github.com/go-task/task/pull/651)).
+- Add `Taskfile.dist.yml` and `Taskfile.dist.yaml` to the supported file
+  name list. [Check out the documentation](https://taskfile.dev/#/usage?id=supported-file-names) for more information
+  ([#498](https://github.com/go-task/task/issues/498), [#666](https://github.com/go-task/task/pull/666)).
+
+## v3.10.0 - 2022-01-04
+
+- A new `--list-all` (alias `-a`) flag is now available. It's similar to the
+  exiting `--list` (`-l`) but prints all tasks, even those without a
+  description
+  ([#383](https://github.com/go-task/task/issues/383), [#401](https://github.com/go-task/task/pull/401)).
+- It's now possible to schedule cleanup commands to run once a task finishes
+  with the `defer:` keyword
+  ([Documentation](https://taskfile.dev/#/usage?id=doing-task-cleanup-with-defer), [#475](https://github.com/go-task/task/issues/475), [#626](https://github.com/go-task/task/pull/626)).
+- Remove long deprecated and undocumented `$` variable prefix and `^` command
+  prefix
+  ([#642](https://github.com/go-task/task/issues/642), [#644](https://github.com/go-task/task/issues/644), [#645](https://github.com/go-task/task/pull/645)).
+- Add support for `.yaml` extension (as an alternative to `.yml`).
+  This was requested multiple times throughout the years. Enjoy!
+  ([#183](https://github.com/go-task/task/issues/183), [#184](https://github.com/go-task/task/pull/184), [#369](https://github.com/go-task/task/issues/369), [#584](https://github.com/go-task/task/issues/584), [#621](https://github.com/go-task/task/pull/621)).
+- Fixed error when computing a variable when the task directory do not exist
+  yet
+  ([#481](https://github.com/go-task/task/issues/481), [#579](https://github.com/go-task/task/pull/579)).
+
+## v3.9.2 - 2021-12-02
+
+- Upgrade [mvdan/sh](https://github.com/mvdan/sh) which contains a fix a for
+  a important regression on Windows
+  ([#619](https://github.com/go-task/task/issues/619), [mvdan/sh#768](https://github.com/mvdan/sh/issues/768), [mvdan/sh#769](https://github.com/mvdan/sh/pull/769)).
+
+## v3.9.1 - 2021-11-28
+
+- Add logging in verbose mode for when a task starts and finishes
+  ([#533](https://github.com/go-task/task/issues/533), [#588](https://github.com/go-task/task/pull/588)).
+- Fix an issue with preconditions and context errors
+  ([#597](https://github.com/go-task/task/issues/597), [#598](https://github.com/go-task/task/pull/598)).
+- Quote each `{{.CLI_ARGS}}` argument to prevent one with spaces to become many
+  ([#613](https://github.com/go-task/task/pull/613)).
+- Fix  nil pointer when `cmd:` was left empty
+  ([#612](https://github.com/go-task/task/issues/612), [#614](https://github.com/go-task/task/pull/614)).
+- Upgrade [mvdan/sh](https://github.com/mvdan/sh) which contains two
+  relevant fixes:
+  - Fix quote of empty strings in `shellQuote`
+    ([#609](https://github.com/go-task/task/issues/609), [mvdan/sh#763](https://github.com/mvdan/sh/issues/763)).
+  - Fix issue of wrong environment variable being picked when there's another
+    very similar one
+    ([#586](https://github.com/go-task/task/issues/586), [mvdan/sh#745](https://github.com/mvdan/sh/pull/745)).
+- Install shell completions automatically when installing via Homebrew
+  ([#264](https://github.com/go-task/task/issues/264), [#592](https://github.com/go-task/task/pull/592), [go-task/homebrew-tap#2](https://github.com/go-task/homebrew-tap/pull/2)).
+
+## v3.9.0 - 2021-10-02
+
+- A new `shellQuote` function was added to the template system
+  (`{{shellQuote "a string"}}`) to ensure a string is safe for use in shell
+  ([mvdan/sh#727](https://github.com/mvdan/sh/pull/727), [mvdan/sh#737](https://github.com/mvdan/sh/pull/737), [Documentation](https://pkg.go.dev/mvdan.cc/sh/v3@v3.4.0/syntax#Quote))
+- In this version [mvdan.cc/sh](https://github.com/mvdan/sh) was upgraded
+  with some small fixes and features
+  - The `read -p` flag is now supported
+    ([#314](https://github.com/go-task/task/issues/314), [mvdan/sh#551](https://github.com/mvdan/sh/issues/551), [mvdan/sh#772](https://github.com/mvdan/sh/pull/722))
+  - The `pwd -P` and `pwd -L` flags are now supported
+    ([#553](https://github.com/go-task/task/issues/553), [mvdan/sh#724](https://github.com/mvdan/sh/issues/724), [mvdan/sh#728](https://github.com/mvdan/sh/pull/728))
+  - The `$GID` environment variable is now correctly being set
+    ([#561](https://github.com/go-task/task/issues/561), [mvdan/sh#723](https://github.com/mvdan/sh/pull/723))
+
+## v3.8.0 - 2021-09-26
+
+- Add `interactive: true` setting to improve support for interactive CLI apps
+  ([#217](https://github.com/go-task/task/issues/217), [#563](https://github.com/go-task/task/pull/563)).
+- Fix some `nil` errors
+  ([#534](https://github.com/go-task/task/issues/534), [#573](https://github.com/go-task/task/pull/573)).
+- Add ability to declare an included Taskfile as optional
+  ([#519](https://github.com/go-task/task/issues/519), [#552](https://github.com/go-task/task/pull/552)).
+- Add support for including Taskfiles in the home directory by using `~`
+  ([#539](https://github.com/go-task/task/issues/539), [#557](https://github.com/go-task/task/pull/557)).
+
+## v3.7.3 - 2021-09-04
+
+- Add official support to Apple M1 ([#564](https://github.com/go-task/task/pull/564), [#567](https://github.com/go-task/task/pull/567)).
+- Our [official Homebrew tap](https://github.com/go-task/homebrew-tap) will
+  support more platforms, including Apple M1
+
+## v3.7.0 - 2021-07-31
+
+- Add `run:` setting to control if tasks should run multiple times or not.
+  Available options are `always` (the default), `when_changed` (if a variable
+  modified the task) and `once` (run only once no matter what).
+  This is a long time requested feature. Enjoy!
+  ([#53](https://github.com/go-task/task/issues/53), [#359](https://github.com/go-task/task/pull/359)).
+
 ## v3.6.0 - 2021-07-10
 
 - Allow using both `sources:` and `status:` in the same task

+```
+
+:::
+
+### Task

+
+```yaml
+tasks:
+  foo:
+    deps: [foo, bar]
+```
+
+:::

+
+:::info
+
+Static and dynamic variables have different syntaxes, like below:
+
+```yaml
+vars:
+  STATIC: static
+  DYNAMIC:
+    sh: echo "dynamic"
+```
+
+:::
+
+### Precondition
+
+| Attribute | Type | Default | Description |

+
+```yaml
+tasks:
+  foo:
+    precondition: test -f Taskfile.yml

+# Changelog
+
+## v3.14.0 - 2022-07-08
+
+- Add ability to override the `.task` directory location with the
+  `TASK_TEMP_DIR` environment variable.
+- 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)).
+- Starting on this release, ARM architecture binaries are been released to Snap
+  as well
+  ([#795](https://github.com/go-task/task/issues/795)).
+- i386 binaries won't be available anymore on Snap because Ubuntu removed the support
+  for this architecture.
+- Upgrade mvdan.cc/sh, which fixes a bug with associative arrays
+  ([#785](https://github.com/go-task/task/issues/785), [mvdan/sh#884](https://github.com/mvdan/sh/issues/884), [mvdan/sh#893](https://github.com/mvdan/sh/pull/893)).
+
+## v3.13.0 - 2022-06-13
+
+- Added `-n` as an alias to `--dry`
+  ([#776](https://github.com/go-task/task/issues/776), [#777](https://github.com/go-task/task/pull/777)).
+- Fix behavior of interrupt (SIGINT, SIGTERM) signals. Task will now give time
+  for the processes running to do cleanup work
+  ([#458](https://github.com/go-task/task/issues/458), [#479](https://github.com/go-task/task/pull/479), [#728](https://github.com/go-task/task/issues/728), [#769](https://github.com/go-task/task/pull/769)).
+- Add new `--exit-code` (`-x`) flag that will pass-through the exit form the
+  command being ran
+  ([#755](https://github.com/go-task/task/pull/755)).
+
+## v3.12.1 - 2022-05-10
+
+- Fixed bug where, on Windows, variables were ending with `\r` because we were
+  only removing the final `\n` but not `\r\n`
+  ([#717](https://github.com/go-task/task/issues/717)).
+
+## v3.12.0 - 2022-03-31
+
+- The `--list` and `--list-all` flags can now be combined with the `--silent`
+  flag to print the task names only, without their description
+  ([#691](https://github.com/go-task/task/pull/691)).
+- Added support for multi-level inclusion of Taskfiles. This means that
+  included Taskfiles can also include other Taskfiles. Before this was limited
+  to one level
+  ([#390](https://github.com/go-task/task/issues/390), [#623](https://github.com/go-task/task/discussions/623), [#656](https://github.com/go-task/task/pull/656)).
+- Add ability to specify vars when including a Taskfile.
+  [Check out the documentation](https://taskfile.dev/#/usage?id=vars-of-included-taskfiles)
+  for more information.
+  ([#677](https://github.com/go-task/task/pull/677)).
+
+## v3.11.0 - 2022-02-19
+
+- Task now supports printing begin and end messages when using the `group`
+  output mode, useful for grouping tasks in CI systems.
+  [Check out the documentation](http://taskfile.dev/#/usage?id=output-syntax) for more information
+  ([#647](https://github.com/go-task/task/issues/647), [#651](https://github.com/go-task/task/pull/651)).
+- Add `Taskfile.dist.yml` and `Taskfile.dist.yaml` to the supported file
+  name list. [Check out the documentation](https://taskfile.dev/#/usage?id=supported-file-names) for more information
+  ([#498](https://github.com/go-task/task/issues/498), [#666](https://github.com/go-task/task/pull/666)).
+
+## v3.10.0 - 2022-01-04
+
+- A new `--list-all` (alias `-a`) flag is now available. It's similar to the
+  exiting `--list` (`-l`) but prints all tasks, even those without a
+  description
+  ([#383](https://github.com/go-task/task/issues/383), [#401](https://github.com/go-task/task/pull/401)).
+- It's now possible to schedule cleanup commands to run once a task finishes
+  with the `defer:` keyword
+  ([Documentation](https://taskfile.dev/#/usage?id=doing-task-cleanup-with-defer), [#475](https://github.com/go-task/task/issues/475), [#626](https://github.com/go-task/task/pull/626)).
+- Remove long deprecated and undocumented `$` variable prefix and `^` command
+  prefix
+  ([#642](https://github.com/go-task/task/issues/642), [#644](https://github.com/go-task/task/issues/644), [#645](https://github.com/go-task/task/pull/645)).
+- Add support for `.yaml` extension (as an alternative to `.yml`).
+  This was requested multiple times throughout the years. Enjoy!
+  ([#183](https://github.com/go-task/task/issues/183), [#184](https://github.com/go-task/task/pull/184), [#369](https://github.com/go-task/task/issues/369), [#584](https://github.com/go-task/task/issues/584), [#621](https://github.com/go-task/task/pull/621)).
+- Fixed error when computing a variable when the task directory do not exist
+  yet
+  ([#481](https://github.com/go-task/task/issues/481), [#579](https://github.com/go-task/task/pull/579)).
+
+## v3.9.2 - 2021-12-02
+
+- Upgrade [mvdan/sh](https://github.com/mvdan/sh) which contains a fix a for
+  a important regression on Windows
+  ([#619](https://github.com/go-task/task/issues/619), [mvdan/sh#768](https://github.com/mvdan/sh/issues/768), [mvdan/sh#769](https://github.com/mvdan/sh/pull/769)).
+
+## v3.9.1 - 2021-11-28
+
+- Add logging in verbose mode for when a task starts and finishes
+  ([#533](https://github.com/go-task/task/issues/533), [#588](https://github.com/go-task/task/pull/588)).
+- Fix an issue with preconditions and context errors
+  ([#597](https://github.com/go-task/task/issues/597), [#598](https://github.com/go-task/task/pull/598)).
+- Quote each `{{.CLI_ARGS}}` argument to prevent one with spaces to become many
+  ([#613](https://github.com/go-task/task/pull/613)).
+- Fix  nil pointer when `cmd:` was left empty
+  ([#612](https://github.com/go-task/task/issues/612), [#614](https://github.com/go-task/task/pull/614)).
+- Upgrade [mvdan/sh](https://github.com/mvdan/sh) which contains two
+  relevant fixes:
+  - Fix quote of empty strings in `shellQuote`
+    ([#609](https://github.com/go-task/task/issues/609), [mvdan/sh#763](https://github.com/mvdan/sh/issues/763)).
+  - Fix issue of wrong environment variable being picked when there's another
+    very similar one
+    ([#586](https://github.com/go-task/task/issues/586), [mvdan/sh#745](https://github.com/mvdan/sh/pull/745)).
+- Install shell completions automatically when installing via Homebrew

+  (`{{shellQuote "a string"}}`) to ensure a string is safe for use in shell
+  ([mvdan/sh#727](https://github.com/mvdan/sh/pull/727), [mvdan/sh#737](https://github.com/mvdan/sh/pull/737), [Documentation](https://pkg.go.dev/mvdan.cc/sh/v3@v3.4.0/syntax#Quote))
+- In this version [mvdan.cc/sh](https://github.com/mvdan/sh) was upgraded
+  with some small fixes and features

+
+- Add official support to Apple M1 ([#564](https://github.com/go-task/task/pull/564), [#567](https://github.com/go-task/task/pull/567)).
+- Our [official Homebrew tap](https://github.com/go-task/homebrew-tap) will
+  support more platforms, including Apple M1
+
+## v3.7.0 - 2021-07-31
+
+- Add `run:` setting to control if tasks should run multiple times or not.
+  Available options are `always` (the default), `when_changed` (if a variable

+- A JSON Schema was published [here](https://json.schemastore.org/taskfile.json)
+  and is automatically being used by some editors like Visual Studio Code
+  ([#135](https://github.com/go-task/task/issues/135)).
+- Print task name before the command in the log output
+  ([#398](https://github.com/go-task/task/pull/398)).
+
+## v3.3.0 - 2021-03-20
+
+- Add support for delegating CLI arguments to commands with `--` and a
+  special `CLI_ARGS` variable
+  ([#327](https://github.com/go-task/task/issues/327)).
+- Add a `--concurrency` (alias `-C`) flag, to limit the number of tasks that
+  run concurrently. This is useful for heavy workloads.
+  ([#345](https://github.com/go-task/task/pull/345)).
+
+## v3.2.2 - 2021-01-12
+
+- Improve performance of `--list` and `--summary` by skipping running shell
+  variables for these flags
+  ([#332](https://github.com/go-task/task/issues/332)).
+- Fixed a bug where an environment in a Taskfile was not always overridable
+  by the system environment
+  ([#425](https://github.com/go-task/task/issues/425)).
+- Fixed environment from .env files not being available as variables
+  ([#379](https://github.com/go-task/task/issues/379)).
+- The install script is now working for ARM platforms
+  ([#428](https://github.com/go-task/task/pull/428)).
+
+## v3.2.1 - 2021-01-09
+
+- Fixed some bugs and regressions regarding dynamic variables and directories
+  ([#426](https://github.com/go-task/task/issues/426)).
+- The [slim-sprig](https://github.com/go-task/slim-sprig) package was updated
+  with the upstream [sprig](https://github.com/Masterminds/sprig).
+
+## v3.2.0 - 2021-01-07
+
+- Fix the `.task` directory being created in the task directory instead of the
+  Taskfile directory
+  ([#247](https://github.com/go-task/task/issues/247)).
+- Fix a bug where dynamic variables (those declared with `sh:`) were not
+  running in the task directory when the task has a custom dir or it was
+  in an included Taskfile
+  ([#384](https://github.com/go-task/task/issues/384)).
+- The watch feature (via the `--watch` flag) got a few different bug fixes and
+  should be more stable now
+  ([#423](https://github.com/go-task/task/pull/423), [#365](https://github.com/go-task/task/issues/365)).
+
+## v3.1.0 - 2021-01-03
+
+- Fix a bug when the checksum up-to-date resolution is used by a task
+  with a custom `label:` attribute
+  ([#412](https://github.com/go-task/task/issues/412)).
+- Starting from this release, we're releasing official ARMv6 and ARM64 binaries
+  for Linux
+  ([#375](https://github.com/go-task/task/issues/375), [#418](https://github.com/go-task/task/issues/418)).
+- Task now respects the order of declaration of included Taskfiles when
+  evaluating variables declaring by them
+  ([#393](https://github.com/go-task/task/issues/393)).
+- `set -e` is now automatically set on every command. This was done to fix an
+  issue where multiline string commands wouldn't really fail unless the
+  sentence was in the last line
+  ([#403](https://github.com/go-task/task/issues/403)).
+
+## v3.0.1 - 2020-12-26
+
+- Allow use as a library by moving the required packages out of the `internal`
+  directory
+  ([#358](https://github.com/go-task/task/pull/358)).
+- Do not error if a specified dotenv file does not exist
+  ([#378](https://github.com/go-task/task/issues/378), [#385](https://github.com/go-task/task/pull/385)).
+- Fix panic when you have empty tasks in your Taskfile
+  ([#338](https://github.com/go-task/task/issues/338), [#362](https://github.com/go-task/task/pull/362)).
+
+## v3.0.0 - 2020-08-16
+
+- On `v3`, all CLI variables will be considered global variables
+  ([#336](https://github.com/go-task/task/issues/336), [#341](https://github.com/go-task/task/pull/341))
+- Add support to `.env` like files
+  ([#324](https://github.com/go-task/task/issues/324), [#356](https://github.com/go-task/task/pull/356)).
+- Add `label:` to task so you can override the task name in the logs
+  ([#321](https://github.com/go-task/task/issues/321]), [#337](https://github.com/go-task/task/pull/337)).
+- Refactor how variables work on version 3
+  ([#311](https://github.com/go-task/task/pull/311)).
+- Disallow `expansions` on v3 since it has no effect.
+- `Taskvars.yml` is not automatically included anymore.
+- `Taskfile_{{OS}}.yml` is not automatically included anymore.
+- Allow interpolation on `includes`, so you can manually include a Taskfile
+  based on operation system, for example.
+- Expose `.TASK` variable in templates with the task name
+  ([#252](https://github.com/go-task/task/issues/252)).
+- Implement short task syntax
+  ([#194](https://github.com/go-task/task/issues/194), [#240](https://github.com/go-task/task/pull/240)).
+- Added option to make included Taskfile run commands on its own directory
+  ([#260](https://github.com/go-task/task/issues/260), [#144](https://github.com/go-task/task/issues/144))
+- Taskfiles in version 1 are not supported anymore
+  ([#237](https://github.com/go-task/task/pull/237)).
+- Added global `method:` option. With this option, you can set a default
+  method to all tasks in a Taskfile
+  ([#246](https://github.com/go-task/task/issues/246)).
+- Changed default method from `timestamp` to `checksum`
+  ([#246](https://github.com/go-task/task/issues/246)).
+- New magic variables are now available when using `status:`:
+  `.TIMESTAMP` which contains the greatest modification date
+  from the files listed in `sources:`, and `.CHECKSUM`, which
+  contains a checksum of all files listed in `status:`.
+  This is useful for manual checking when using external, or even remote,
+  artifacts when using `status:`
+  ([#216](https://github.com/go-task/task/pull/216)).
+- We're now using [slim-sprig](https://github.com/go-task/slim-sprig) instead of
+  [sprig](https://github.com/Masterminds/sprig), which allowed a file size
+  reduction of about 22%
+  ([#219](https://github.com/go-task/task/pull/219)).
+- We now use some colors on Task output to better distinguish message types -
+  commands are green, errors are red, etc
+  ([#207](https://github.com/go-task/task/pull/207)).
+
+## v2.8.1 - 2020-05-20
+
+- Fix error code for the `--help` flag
+  ([#300](https://github.com/go-task/task/issues/300), [#330](https://github.com/go-task/task/pull/330)).
+- Print version to stdout instead of stderr
+  ([#299](https://github.com/go-task/task/issues/299), [#329](https://github.com/go-task/task/pull/329)).
+- Supress `context` errors when using the `--watch` flag
+  ([#313](https://github.com/go-task/task/issues/313), [#317](https://github.com/go-task/task/pull/317)).
+- Support templating on description
+  ([#276](https://github.com/go-task/task/issues/276), [#283](https://github.com/go-task/task/pull/283)).
+
+## v2.8.0 - 2019-12-07
+
+- Add `--parallel` flag (alias `-p`) to run tasks given by the command line in
+  parallel
+  ([#266](https://github.com/go-task/task/pull/266)).
+- Fixed bug where calling the `task` CLI only informing global vars would not
+  execute the `default` task.
+- Add hability to silent all tasks by adding `silent: true` a the root of the
+  Taskfile.
+
+## v2.7.1 - 2019-11-10
+
+- Fix error being raised when `exit 0` was called
+  ([#251](https://github.com/go-task/task/issues/251)).
+
+## v2.7.0 - 2019-09-22
+
+- Fixed panic bug when assigning a global variable
+  ([#229](https://github.com/go-task/task/issues/229), [#243](https://github.com/go-task/task/issues/234)).
+- A task with `method: checksum` will now re-run if generated files are deleted
+  ([#228](https://github.com/go-task/task/pull/228), [#238](https://github.com/go-task/task/issues/238)).
+
+## v2.6.0 - 2019-07-21
+
+- Fixed some bugs regarding minor version checks on `version:`.
+- Add `preconditions:` to task
+  ([#205](https://github.com/go-task/task/pull/205)).
+- Create directory informed on `dir:` if it doesn't exist
+  ([#209](https://github.com/go-task/task/issues/209), [#211](https://github.com/go-task/task/pull/211)).
+- We now have a `--taskfile` flag (alias `-t`), which can be used to run
+  another Taskfile (other than the default `Taskfile.yml`)
+  ([#221](https://github.com/go-task/task/pull/221)).
+- It's now possible to install Task using Homebrew on Linux
+  ([go-task/homebrew-tap#1](https://github.com/go-task/homebrew-tap/pull/1)).
+
+## v2.5.2 - 2019-05-11
+
+- Reverted YAML upgrade due issues with CRLF on Windows
+  ([#201](https://github.com/go-task/task/issues/201), [go-yaml/yaml#450](https://github.com/go-yaml/yaml/issues/450)).
+- Allow setting global variables through the CLI
+  ([#192](https://github.com/go-task/task/issues/192)).
+
+## 2.5.1 - 2019-04-27
+
+- Fixed some issues with interactive command line tools, where sometimes
+  the output were not being shown, and similar issues
+  ([#114](https://github.com/go-task/task/issues/114), [#190](https://github.com/go-task/task/issues/190), [#200](https://github.com/go-task/task/pull/200)).
+- Upgraded [go-yaml/yaml](https://github.com/go-yaml/yaml) from v2 to v3.
+
+## v2.5.0 - 2019-03-16
+
+- We moved from the taskfile.org domain to the new fancy taskfile.dev domain.
+  While stuff is being redirected, we strongly recommend to everyone that use
+  [this install script](https://taskfile.dev/#/installation?id=install-script)
+  to use the new taskfile.dev domain on scripts from now on.
+- Fixed to the ZSH completion
+  ([#182](https://github.com/go-task/task/pull/182)).
+- Add [`--summary` flag along with `summary:` task attribute](https://taskfile.org/#/usage?id=display-summary-of-task)

+## Interactive CLI application
+
+When running interactive CLI applications inside Task they can sometimes behave
+weirdly, especially when the [output mode](#output-syntax) is set to something
+other than `interleaved` (the default), or when interactive apps are run in
+parallel with other tasks.
+
+The `interactive: true` tells Task this is an interactive application and Task
