Here it shows that only v3.0.0 is available:  
[https://yarnpkg.com/package/@openzeppelin/contracts-ethereum-package](https://yarnpkg.com/package/@openzeppelin/contracts-ethereum-package)

One the github repo I can see the latest release as v3.3.0

> **[Releases · OpenZeppelin/openzeppelin-contracts-upgradeable](https://github.com/OpenZeppelin/openzeppelin-contracts-upgradeable/releases)**
>
> ble/releases

Which what I would like to use in project, so I can use solidity 0.7 with upgradeable contracts

**💻 Environment**

That it 🙂

**🔢 Code to reproduce**

Try add this to your package.json  
“@openzeppelin/contracts-ethereum-package”: “^3.4.0”,  
and hit ‘yarn’ to install the node modules.

That’s because the `contracts-ethereum-package` repository transitioned to `contracts-upgradeable`, but they’re still two different npm packages (github repositories and npm packages aren’t related 1-to-1). Try with

```auto
$ yarn add @openzeppelin/contracts-upgradeable

```
