-_**⚠️ Important note:** The TEE/SGX pallet and environement are improving! Both the secret NFT & Capsule NFT pallets are impacted. If you intend to create either some Secret NFT or Capsule NFT **on Alphanet**, this release candidate package version **must be installed**. The new TEE/SGX pallet and environement base code is not yet available on the Mainnet. If you do not use any of the Secret NFT or Caspule NFT privacy features, you can still go with the lastest stable package version or start using this one to avoid any changes later. Please keep looking at the [Discussion #175 on the Ternoa SDK repository](https://github.com/capsule-corp-ternoa/ternoa-js/discussions/175), to get the last information about those changes and the mainnet release schedule!_
