| Release Notes | ||
| ------------- | ||
| This v2.2.4 version is the latest of the v2.2 long-term support (LTS) release | ||
| of the fabric-node-sdk packages that support Fabric 2.x, and supersedes previous | ||
| v2.x releases. Please see the Fabric LTS release strategy document for more | ||
| information on LTS releases: | ||
|
|
||
| https://github.com/hyperledger/fabric-rfcs/blob/master/text/0005-lts-release-strategy.md | ||
|
|
||
| If migrating a client application from an earlier version of the API, consult | ||
| the migration tutorial for details of potentially breaking changes and recommended actions: | ||
|

||

|
|
||
| Changes in v2.2.4: | ||
|
|
||
| - The fabric-network HSM wallet provider will now save HSM private key | ||
| handles to provide access to HSM identities across sessions. The PKCS11 key | ||
| implementation has been updated to return the string representation of the | ||
| HSM private key handle when requesting the private key. | ||
| To save an HSM identity: | ||
| // enroll as usual | ||
| const enrollmentResults = await hsmCAClient.enroll(options); | ||
| // from the enrollment results get the info to save | ||
| const identity: HsmX509Identity = { | ||
| credentials: { | ||
| certificate: enrollmentResults.certificate, | ||
| privateKey: enrollmentResults.key.toBytes() | ||
| }, | ||
| mspId: 'org1', | ||
| type: 'HSM-X.509', | ||
| }; | ||
| await wallet.put('bob', identity); | ||
|
|
||
| - The fabric-network query handlers will now include the chaincode result (payload) | ||
| in the error object when a chaincode query fails (`transaction.evaluate()`) and | ||
| the non "200" success status of the chaincode response includes a payload. | ||
| To see the payload: | ||
| try { | ||
| const results = transaction.evaluate(arg1); | ||
| } catch(error) { | ||
| console.log('Chaincode results:' + error.payload.toString()); | ||
| } | ||
|
|
||
| - Fabric system chaincodes may now be used when the gateway is connected using | ||
| the discovery service. The performance enhancement to seed endorsements and | ||
| queries only to peers that the discovery service has indicated are running the | ||
| requested chaincode will not apply to system chaincodes 'cscc', 'lscc', and 'qscc'. | ||
| The discovery service does not show these legacy system chaincodes because they | ||
| do not have endorsement policies. | ||
|
|
||
| Major changes from v1.4: | ||
|
|
||
| - The fabric-client package has been removed. Client applications should use | ||
| the Fabric Programming Model APIs from the fabric-network package. | ||
|
|
||
| - The underlying APIs that interface with the gRPC layer have been | ||
| reimplemented in the fabric-common package and should not be used directly | ||
| by client applications. | ||
|
|
||
| - Simplified wallet management, which is portable across SDK languages and | ||
| with pluggable persistent storage. More information can be found here: | ||
|
|
||
| https://hyperledger.github.io/fabric-sdk-node/master/tutorial-wallet.html | ||
|
|
||
| - New eventing implementation in fabric-network. Client application code can | ||
| listen for block events using Network.addBlockListener(), and listen for | ||
| contract events using Contract.addContractListener(). The Network object | ||
| also provides capability to listen for transaction commit events, | ||
| specifically to support the implementation of custom event handlers. More | ||
| information can be found here: | ||
