• Improve extensibility of ERC1155 (Improve extensibility of ERC1155 #2003)
• Port to Solidity v0.6
• Re-review the code, mostly for security issues.
• Add more tests, increase test coverage.
• Compare with Augur's implementation.
• Review URI support. (ERC1155: Add a simple catch-all implementation of the metadata URI interface #2029)
• Hook (single flavor using arrays)
• Pausable
• Burnable (single & batched)
• Preset (MinterPauser)
• Review revert reasons
• Documentation (API, and mention in tokens guide)

@nventuro would it be possible to add ERC1155 support to https://github.com/OpenZeppelin/openzeppelin-contracts-ethereum-package?

Seems like it would be an easy port. I can even port it myself if necessary.

Hello @JosephBagaric! Thank you for bringing this up.

Yes, it will be included in that package as well. We'll port it ourselves once the code is finished - we use an automated tool for this task to reduce the chance of human errors when migrating constructors.
