+## [v1.13.0]
+
+### Breaking
+
+The npm dependency @openzeppelin/contracts is now mapped to the local path `@openzeppelin/contracts-v4`.
+This frees up the default path `@openzeppelin/contracts` for v5 which most new Solidity projects use.
+
+In order to use this package in a **foundry project (new or existing) with dependencies installed as git submodules**, this steps are recommended:
+
+1. Add openzeppelin-contracts v4 as a submodule:
+```
+git submodule add -b release-v4.9 https://github.com/OpenZeppelin/openzeppelin-contracts lib/openzeppelin-contracts-v4
+```
+Note the explicit local path with v4 postfix.
+
+2. Add this mapping to `foundry.toml` or `remappings.txt` (depending on where they are located in your project):
+```
+"@openzeppelin/contracts-v4/=lib/openzeppelin-contracts-v4/contracts/"
+```
+
+That way, projects can use the import path `@openzeppelin/contracts` for openzeppelin v5. This is the default when using npm for installing the openzeppelin dependency.
+
+**Note:**  
+foundry by default auto-detects mappings based on the contents of the lib directory and nested foundry configuration files.
+Because of this, it may automatically add a mapping `openzeppelin/=lib/openzeppelin-contracts-v4/contracts/` .
+In case you're using the import path `openzeppelin/...` in your project, that may not be what you want.
+In this case you can either change the import path to something else, or you can disable mapping auto-detection with `auto_detect_remappings = false` (see [docs](https://book.getfoundry.sh/reference/config/solidity-compiler#auto_detect_remappings)). If you disable it, you may need to explicitly add some mappings, e.g. for forge-std.
+
+In order to use this package in a **project with dependencies managed by npm packages**, you don't need to do anything.
+Except: if you relied on the openzeppelin-contracts v4 dependency installed by this package, you now need to either also adjust the import path, or explicity add the dependency with the default path to your project.
