@@ -18,86 +18,122 @@ The `version:` key on Taskfile accepts a semver string, so either `2`, `2.0` or
 `2.1` features, but if you choose to use `2`, then any `2.x.x` features will be
 available, but not `3.0.0+`.
 
-## Version 1
+## Version 3 ![latest](https://img.shields.io/badge/latest-brightgreen)
 
-> NOTE: Taskfiles in version 1 are not supported on Task >= v3.0.0 anymore.
+These are some major changes done on `v3`:
 
-In the first version of the `Taskfile`, the `version:` key was not available,
-because the tasks was in the root of the YAML document. Like this:
+- Task's output will now be colored
+- Added support for `.env` like files
+- Added `label:` setting to task so one can override how the task name appear in
+  the logs
+- A global `method:` was added to allow setting the default method, and Task's
+  default changed to `checksum`
+- Two magic variables were added when using `status:`: `CHECKSUM` and
+  `TIMESTAMP` which contains, respectively, the md5 checksum and greatest
+  modification timestamp of the files listed on `sources:`
+- Also, the `TASK` variable is always available with the current task name
+- CLI variables are always treated as global variables
+- Added `dir:` option to `includes` to allow choosing on which directory an
+  included Taskfile will run:
 
 ```yaml
-echo:
-  cmds:
-    - echo "Hello, World!"
+includes:
+  docs:
+    taskfile: ./docs
+    dir: ./docs
 ```
 
-The variable priority order was also different:
+- Implemented short task syntax. All below syntaxes are equivalent:
 
-1. Call variables
-2. Environment
-3. Task variables
-4. `Taskvars.yml` variables
+```yaml
+version: '3'
 
-## Version 2.0
+tasks:
+  print:
+    cmds:
+      - echo "Hello, World!"
+```
 
-At version 2, we introduced the `version:` key, to allow us to evolve Task with
-new features without breaking existing Taskfiles. The new syntax is as follows:
+```yaml
+version: '3'
+
+tasks:
+  print:
+    - echo "Hello, World!"
+```
 
 ```yaml
-version: '2'
+version: '3'
 
 tasks:
-  echo:
-    cmds:
-      - echo "Hello, World!"
+  print: echo "Hello, World!"
 ```
 
-Version 2 allows you to write global variables directly in the Taskfile, if you
-don't want to create a `Taskvars.yml`:
+- There was a major refactor on how variables are handled. They're now easier to
+  understand. The `expansions:` setting was removed as it became unnecessary.
+  This is the order in which Task will process variables, each level can see the
+  variables set by the previous one and override those.
+  - Environment variables
+  - Global + CLI variables
+  - Call variables
+  - Task variables
