 # Changelog
 
+## v3.20.0 - 2023-01-14
+
+- Improve behavior and performance of status checking when using the
+  `timestamp` mode
+  ([#976](https://github.com/go-task/task/issues/976), [#977](https://github.com/go-task/task/pull/977) by @aminya).
+- Performance optimizations were made for large Taskfiles
+  ([#982](https://github.com/go-task/task/pull/982) by @pd93).
+- Add ability to configure options for the [`set`](https://www.gnu.org/software/bash/manual/html_node/The-Set-Builtin.html)
+  and [`shopt`](https://www.gnu.org/software/bash/manual/html_node/The-Shopt-Builtin.html) builtins
+  ([#908](https://github.com/go-task/task/issues/908), [#929](https://github.com/go-task/task/pull/929) by @pd93, [Documentation](http://taskfile.dev/usage/#set-and-shopt)).
+- Add new `platforms:` attribute to `task` and `cmd`, so it's now possible to
+  choose in which platforms that given task or command will be run on. Possible
+  values are operating system (GOOS), architecture (GOARCH) or a combination of
+  the two. Example: `platforms: [linux]`, `platforms: [amd64]` or
+  `platforms: [linux/amd64]`. Other platforms will be skipped
+  ([#978](https://github.com/go-task/task/issues/978), [#980](https://github.com/go-task/task/pull/980) by @leaanthony).

 ## v3.19.1 - 2022-12-31

+## Platform specific tasks and commands
+
+If you want to restrict the running of tasks to explicit platforms, this can be achieved
+using the `platforms:` key. Tasks can be restricted to a specific OS, architecture or a
+combination of both.
+On a mismatch, the task or command will be skipped, and no error will be thrown.
+
+The values allowed as OS or Arch are valid `GOOS` and `GOARCH` values, as
+defined by the Go language
+[here](https://github.com/golang/go/blob/master/src/go/build/syslist.go).
+
+The `build-windows` task below will run only on Windows, and on any architecture:
+
+```yaml
+version: '3'
+
+tasks:
+  build-windows:
+    platforms: [windows]
+    cmds:
+      - echo 'Running command on Windows'

+
+This can be restricted to a specific architecture as follows:
+

+version: '3'

+tasks:
+  build-windows-amd64:
+    platforms: [windows/amd64]
+    cmds:
+      - echo 'Running command on Windows (amd64)'
+```
+
+It is also possible to restrict the task to specific architectures:

+tasks:
+  build-amd64:
+    platforms: [amd64]
+    cmds:

+Multiple platforms can be specified as follows:

+    platforms: [windows/amd64, darwin]
+    cmds:
