 #### Upcoming Changes
 
+* feat(BREAKING): [#1824](https://github.com/lambdaclass/cairo-vm/pull/1824):
+    * Add support for dynamic layout
+    * CLI change(BREAKING): The flag `cairo_layout_params_file` must be specified when using dynamic layout.
+    * Signature change(BREAKING): Both `CairoRunner::new` and `CairoRunner::new_v2` now receive an `Option<CairoLayoutParams>`, used only with dynamic layout.
+
 * chore: bump pip `cairo-lang` 0.13.2 [#1827](https://github.com/lambdaclass/cairo-vm/pull/1827)
 
 * chore: bump `cairo-lang-` dependencies to 2.8.0 [#1833](https://github.com/lambdaclass/cairo-vm/pull/1833/files)

@@ -182,6 +182,8 @@ The cairo-vm-cli supports the following optional arguments:
 
 - `run_from_cairo_pie`: Runs a Cairo PIE instead of a compiled json file. The name of the file will be the first argument received by the CLI (as if it were to run a normal compiled program). Can only be used if proof_mode is not enabled.
 
+- `cairo_layout_params_file`: Only used with dynamic layout. Receives the name of a json file with the dynamic layout parameters.

 For example, to obtain the air public inputs from a fibonacci program run, we can run :
 
 ```bash
