Anything other than the operations above will probably cause a collision. Please refer to Open Zeppelin Upgradeable

## Versioning
|
||||
|
||||
We use [Semantic Versioning](https://semver.org/) for our releases. When upgrading the contract, update the npm package version using
|
||||
`npm version <new version number> --no-git-tag-version`. Also, modify the hard-coded value in `version()` method in
|
||||
[the `Pyth.sol` contract](./contracts/pyth/Pyth.sol) to the new version. Then, after your PR is merged in main, create a release like with tag `pyth-evm-contract-v<x.y.z>`. This will help developers to be able to track code changes easier.
