-# Migrate from v0.8 to v0.9
 
-Heta compiler of **version 0.9** follows the [Heta standard](https://hetalang.github.io/#/specifications/) of **version 0.5.0**.
+# Migration from v0.8 to v0.9
 
-To use the newer Heta compiler you should make some updates to the platform files. To see the other updates see [change log](./CHANGELOG).
+The v0.9 release of Heta includes improvements in export flexibility, support for new formats, and better tooling for the declaration files.
 
-See also [Migrate to v0.6](./migrate-to-v0.6), [Migrate to v0.7](./migrate-to-v0.7), [Migrate to v0.8](./migrate-to-v0.8).
+The **v0.9** version of the Heta compiler adheres to the [Heta standard](https://hetalang.github.io/#/specifications/) **v0.5.0**.
 
-## Changes in declaration (platform.json) file
+To use the latest Heta compiler, you will need to update some platform files. For other updates, refer to the [changelog](./CHANGELOG).
 
-The new version uses YAML format (instead of JSON) for declaration file. The new format is more flexible and allows to use comments and multiline strings.
+You may also want to check the previous migration guides: [Migrate to v0.6](./migrate-to-v0.6), [Migrate to v0.7](./migrate-to-v0.7), and [Migrate to v0.8](./migrate-to-v0.8).
 
-Users can use JSON format for declaration file without restrictions but default YAML files will be generated with `heta init`.
+## Changes to the Declaration (platform.json) File
 
-## Replacement of inline #export actions by export array in declaration
+The new version uses the YAML format (instead of JSON) for the declaration file. YAML is more flexible, supporting comments and multiline strings.
 
-The new version uses `export` array in declaration file to define the list of actions which should be exported.
+You can still use JSON format for declaration files without restrictions, but YAML files will now be generated by default when using `heta init`.
 
-Another option is to use `--export` property in CLI command. See details in [CLI documentation](./cli-references.md).
+## Replacement of Inline `#export` Actions with an `export` Array in Declarations
 
-The old inline export syntax will be supported in the current version (as depricated) but it will be removed in the future.
+In this version, the `export` array is used in the declaration file to specify the list of actions to be exported.
 
-## Update platforms to support new features
+Alternatively, you can use the `--export` option in CLI commands. For more details, refer to the [CLI documentation](./cli-references.md).
 
-1. **Check** that your platform can be build without errors in the current builder v0.8.x.
+The old inline export syntax will be deprecated but supported in the current version. However, it will be removed in future versions.
 
-    *If you use Git you should commit the latest changes before updating formats.*
+## Updating Platforms to Support New Features
 
-1. Install the latest version of **Heta compiler**.
+1. **Ensure** your platform builds without errors using the current v0.8.x builder.
 
-    ```bash
-    npm install -g heta-compiler
-    heta -v
-    # must be v0.9.0 or newer
-    ```
+   *If you're using Git, it is recommended to commit the latest changes before updating the formats.*
 
-1. If you use declaration file **platform.json** update the property to `builderVersion: ^0.9.0` and change file name to **platform.yml** (optional).
+2. Install the latest version of the **Heta compiler**:
 
-    ```yml
-    # in platform.yml
-    {
-        "builderVersion": "^0.9.0",
-        "id": "my-platform",
-        "notes": "platform notes",
-        "version": "v0.1.0",
-        ...
-    }
-    ```
+   ```bash
+   npm install -g heta-compiler
+   heta -v
+   # should return v0.9.0 or newer
+   ```
 
-1. Remove unnecessary properties from the declaration file if you used them before:
+3. If you're using the **platform.json** declaration file, update the `builderVersion` property to `^0.9.0`, and optionally rename the file to **platform.yml**.
+
+   ```yml
+   # in platform.yml
+   {
+       "builderVersion": "^0.9.0",
+       "id": "my-platform",
+       "notes": "platform notes",
+       "version": "v0.1.0",
+       ...
+   }
+   ```
+
+4. Remove any unnecessary properties from the declaration file if you had used them previously:
 
-        - `options.skipExport`: use `export: []` instead
-        - `options.juliaOnly`: use `export: [{format: Julia}]` instead
-
-1. If you used command line options to supress export with `heta build --no-export` then you should use now `heta build --export ''`.
-
-If you used line options to build julia code only with `heta build --julia-only` then you should use now `heta build --export 'Julia'`.
-
-1. Remove all inline `#export` actions from the .heta files and add them to the `export` array in the declaration file.
-
-See details in [export formats](./export-formats.md)
-
-    **Before**
-    ```hetas
-    // in index.heta
-    #export {format: DBSolve, filepath: model, powTransform: function};
-    #export {format: SBML, version: L3V2};
-    ```
-
-    **After**
-    ```yaml
-    # in platform.yml
-    ...
-    export: [
-        {format: DBSolve, filepath: model, powTransform: function},
-        {format: SBML, version: L3V2}
-    ]
-    ```
-
-    **Or After**
-    ```json
-    # in platform.json
-    ...
-    "export": [
-        {"format": "DBSolve", "filepath": "model", "powTransform": "function"},
-        {"format": "SBML", "version": "L3V2"}
-    ]
-    ```
-
-1. Check building with `heta build` and make a commit if you use git.
+    - `options.skipExport`: replace with `export: []`
+    - `options.juliaOnly`: replace with `export: [{format: Julia}]`
+
+5. If you were using command line options to suppress export with `heta build --no-export`, now use `heta build --export ''`.
+
+   If you previously used `heta build --julia-only` to build only Julia code, now use `heta build --export 'Julia'`.
+
+6. Remove all inline `#export` actions from your `.heta` files and move them to the `export` array in the declaration file.
+
+   Refer to [export formats](./export-formats.md) for more details.
+
+   **Before:**
+   ```heta
+   // in index.heta
+   #export {format: DBSolve, filepath: model, powTransform: function};
+   #export {format: SBML, version: L3V2};
+   ```
+
+   **After (YAML format):**
+   ```yaml
+   # in platform.yml
+   ...
+   export: [
+       {format: DBSolve, filepath: model, powTransform: function},
+       {format: SBML, version: L3V2}
+   ]
+   ```
+
+   **Or After (JSON format):**
+   ```json
+   # in platform.json
+   ...
+   "export": [
+       {"format": "DBSolve", "filepath": "model", "powTransform": "function"},
+       {"format": "SBML", "version": "L3V2"}
+   ]
+   ```
+
+7. Test the build with `heta build`, and if you're using Git, make a commit.
