[Changes][v0.14.1]

<a id="v0.14.0"></a>

This release introduced a new high-level Account Key API and improves the interpreter performance. The current low-level Account Key API is now deprecated and will be removed in a future release. Please switch to the new one.

The following example transaction demonstrates the functionality:

transaction {
	prepare(signer: AuthAccount) {
		let newPublicKey = PublicKey(
			publicKey: "010203".decodeHex(),
			signatureAlgorithm: SignatureAlgorithm.ECDSA_P256
		)

		// Add a key
		let addedKey = signer.keys.add(
			publicKey: newPublicKey,
			hashAlgorithm: HashAlgorithm.SHA3_256,
			weight: 100.0
		)


		// Retrieve a key
		let sameKey = signer.keys.get(keyIndex: addedKey.keyIndex)


		// Revoke a key
		signer.keys.revoke(keyIndex: addedKey.keyIndex)
	}
}

⭐ Features

• Introduce a new high-level Account Key API (#633) @SupunS
• Allow the Language Server to be debugged (#663) @turbolent

💥 Breaking Changes

The Crypto contract has changed in a backwards-incompatible way, so the types and values it declared could be used in the new Account Key API:

• The struct Crypto.PublicKey was replaced by the new built-in global struct PublicKey. There is no need anymore to import the Crypto contract to work with public keys.

• The struct Crypto.SignatureAlgorithm was replaced with the new built-in global enum SignatureAlgorithm. There is no need anymore to import the Crypto contract to work with signature algorithms.

• The struct Crypto.HashAlgorithm was replaced with the new built-in global enum HashAlgorithm. There is no need anymore to import the Crypto contract to work with hash algorithms.

• The signature algorithm value Crypto.ECDSA_Secp256k1 was replaced with the new built-in enum case SignatureAlgorithm.ECDSA_Secp256k1

• The signature algorithm value Crypto.ECDSA_P256 was replaced with the new built-in enum case SignatureAlgorithm.ECDSA_P256

• The hash algorithm Crypto.SHA3_256 was replaced with the new built-in enum case HashAlgorithm.SHA3_256

• The hash algorithm Crypto.SHA2_256 was replaced with the new built-in enum case HashAlgorithm.SHA2_256
