 # Changelog
 
+## 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
+  ([#411](https://github.com/go-task/task/issues/411), [#427](https://github.com/go-task/task/issues/427), [#477](https://github.com/go-task/task/pull/477)).
+- Small optimization and bug fix: don't compute variables if not needed for
+  `dotenv:` ([#517](https://github.com/go-task/task/issues/517)).
+
+## v3.5.0 - 2021-07-04
+
+- Add support for interpolation in `dotenv:`
+  ([#433](https://github.com/go-task/task/discussions/433), [#434](https://github.com/go-task/task/issues/434), [#453](https://github.com/go-task/task/pull/453)).
+
+## v3.4.3 - 2021-05-30
+
+- Add support for the `NO_COLOR` environment variable.
+  ([#459](https://github.com/go-task/task/issues/459), [fatih/color#137](https://github.com/fatih/color/pull/137)).
+- Fix bug where sources were not considering the right directory
+  in `--watch` mode
+  ([#484](https://github.com/go-task/task/issues/484), [#485](https://github.com/go-task/task/pull/485)).
+
+## v3.4.2 - 2021-04-23
+
+- On watch, report which file failed to read
+  ([#472](https://github.com/go-task/task/pull/472)).
+- Do not try to catch SIGKILL signal, which are not actually possible
+  ([#476](https://github.com/go-task/task/pull/476)).
+- Improve version reporting when building Task from source using Go Modules
+  ([#462](https://github.com/go-task/task/pull/462), [#473](https://github.com/go-task/task/pull/473)).
+
+## v3.4.1 - 2021-04-17
+
+- Improve error reporting when parsing YAML: in some situations where you
+  would just see an generic error, you'll now see the actual error with
+  more detail: the YAML line the failed to parse, for example
+  ([#467](https://github.com/go-task/task/issues/467)).
+- 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

+# Community
+
+Some of the work to improve the Task ecosystem is done by the community, be
+it installation methods or integrations with code editor. I (the author) am
+thankful for everyone that helps me to improve the overall experience.
+
+## Editor Integrations
+
+### JSON Schema
+
+[@KROSF](https://github.com/KROSF) worked on a JSON Schema [into this Gist](https://gist.github.com/KROSF/c5435acf590acd632f71bb720f685895),
+which later was made officially available by [@Crandel](https://github.com/Crandel)
+at [https://json.schemastore.org/taskfile.json](https://json.schemastore.org/taskfile.json).
+Further improvements are possible by opening pull requests changing
+[this file](https://github.com/SchemaStore/schemastore/blob/master/src/schemas/json/taskfile.json).
+Some code editors, like Visual Studio Code, make use of Schema Store
+automatically.
+
+### Visual Studio Code extension
+
+Additionally, there's also some work done by
+[@paulvarache](https://github.com/paulvarache) in making an Visual Studio Code
+extension, which has its code [here](https://github.com/paulvarache/vscode-taskfile)
+and is published [here](https://marketplace.visualstudio.com/items?itemName=paulvarache.vscode-taskfile).
+
+### Sublime Text 4 package
+
+There is a convenience wrapper for initializing and running tasks from Sublime Text's command palette. The package is 
+developed by [@biozz](https://github.com/biozz), the source code is available [here](https://github.com/biozz/sublime-taskfile)
+and it is published on Package Control [here](https://packagecontrol.io/packages/Taskfile).
+
+## Installation methods
+
+Some installation methods are maintained by third party:
+
+- [GitHub Actions](https://github.com/arduino/setup-task)
+  by [@arduino](https://github.com/arduino)
+- [AUR](https://aur.archlinux.org/packages/taskfile-git)
+  by [@kovetskiy](https://github.com/kovetskiy)
+- [Scoop](https://github.com/lukesampson/scoop-extras/blob/master/bucket/task.json)
+
+## More
+
+Also, thanks for all the [code contributors](https://github.com/go-task/task/graphs/contributors),
+[financial contributors](https://opencollective.com/task), all those who
+[reported bugs](https://github.com/go-task/task/issues?q=is%3Aissue) and
+[answered questions](https://github.com/go-task/task/discussions).

+If a task executed by multiple `cmds` or multiple `deps` you can control
+when it is executed using `run`. `run` can also be set at the root
+of the Taskfile to change the behavior of all the tasks unless explicitly
+overridden.
+
+Supported values for `run`:
+
+ * `always` (default) always attempt to invoke the task regardless of the
+  number of previous executions
+ * `once` only invoke this task once regardless of the number of references
+ * `when_changed` only invokes the task once for each unique set of variables
