Feature Request: Add Hardhat v3 Support

[0xask3]

Requesting support for Hardhat v3 in @openzeppelin/hardhat-upgrades plugin to enable upgradeable contract deployments and management with the latest Hardhat version.

The @openzeppelin/hardhat-upgrades plugin (v3.9.1) is currently incompatible with Hardhat v3.0.6, preventing users from utilizing upgradeable contract functionality when migrating to the latest Hardhat version.

Expected Behavior
The plugin should work seamlessly with Hardhat v3, providing:

• Upgradeable contract deployment
• Contract upgrades
• Proxy management
• Storage layout validation

Current Behavior

• Plugin import fails with package export error
• No access to hre.upgrades functionality
• Cannot deploy upgradeable contracts

We are working together with Nomic on it.

HH3 is missing some hooks for our validation parsing, and the cheat codes for solidity testing are not 100% complete.

Hang in there a bit longer, we will be delivering this!

It is taking a bit longer cause hh3 was not 100% compatible to all the features we were using in hh2 for this plugin.
