[2.1.0] - 2022-11-08

Added

Added support for AES password encryption
Added bridge client to connect directly to Trinci node via socket and listed for events in real time. Not available in browsers as there's no support for direct socket connections.
Added TransactionEvent message type.
general usage data signature creation/verification functions added to main export.
Transaction schema management
T2 Blockchain Tool added to repository. (/misc/t2_bc_tool)
Client.getNodeInfo() method (node version 0.2.8+)
elliptic curve point compression/decompression is now supported (only secp384r1 for now)
added IEEE P1363 => ASN.1 signature conversion function
Added AbortController and timeout support to t2lib.Client
generic Transaction class is now able to determine the exact verification logic based on transaction tag.
bulk root transaction schema now automatically changed to empty bulk root schema when necessary
added "Core" export to lib

Changed

base58 library used for conversions changed
default client network is now '' (empty string)
data requested from an account are now returned as Uint8Array
block index can now be passed to Client.blockData() as a hex string to fix JS number limitations for big UInt64 numbers

Fixed

certificate verification bug fixed
fixed fome unwanted overrides of the base class methods by child classes
fixed bulk receipt format

[2.0.6] - 2022-03-28

Added

AES key management.

[2.0.5] - 2022-03-18

Added

Exported transactions import/export interfaces.

[2.0.4] - 2022-02-02

Added

Reintroduced t2lib.Utils.getSaltAndIV(); method.

[2.0.3] - 2022-01-31

Changed

Transaction schema members now contain actual schema hashes.

[2.0.2] - 2022-01-31

Changed

ECDHKeyPair()/ECDSAKeyPair() constructors now accept custom parameters. If no params were provided, defaults are used.

Added

Schema files for various transaction types.

[2.0.1] - 2022-01-19

Changed

Added maxFuel parameter to prepareUnsignedTx(), prepareTx() and prepareAndSubmitTx() client methods, which should've been done in 2.0.0.

[2.0.0] - 2022-01-18

Changed

event data member name changed from event_data to eventData inside receipt's events to respect project's casing rules.
Transaction's accessors have now been moved to transaction's data member, which now is a separate class. So to access transaction's data members you need to use tx.data.accountId() instead of tx.accountId().
Old Transaction class is now called UnitaryTransaction. Use specific transaction classes (Bulk, BulkNode, BulkRoot, Unitary) to create transaction of the desired type. Generic Transaction class can be used to parse/verify avery other transaction type.

Added

added Transaction.getTicket() method, which computes transaction ticket without submitting it to the blockchain.
added client.waitForBulkTicket() and client.bulkTxReceipt() methods. However bulk transactions can be managed with old client.waitForTicket() and client.txReceipt() methods.
added client.getBlockchainSettings() method which can get some settings (not yet network name).
added Bulk Root, Bulk Node, and Bulk transactions classes.
added schema field to signable (and, therefore, to transactions, certificates and delegations).

Removed

removed client.registeredAssetsList() method as it cannot be used anymore.

[1.6.4] - 2021-12-02

Added

List of events fired by smart contract added to transaction receipt.

[1.6.3] - 2021-11-25

Changed

License changed.

Added

License, changelog and readme files added to npm package.

[1.6.2] - 2021-11-23

Changed

Nothing. 1.6.0 was published again on NPM as 1.6.1 by mistake. Now to publish the new code on NPM we need to increment the version again, even if nothing has actually changed.

[1.6.1] - 2021-11-23

Added

Added ecdsa_secp256r1 keys default parameters (t2lib.CryptoDefaults.ECDSAP256R1KeyPairParams)

[1.6.0] - 2021-11-08

Changed

schema and maxFuel fields added to transactions (not compatible with core versions prior to 0.2.3-rc1).
burnedFuel field added to trancsaction receipt (not compatible with core versions prior to 0.2.3-rc1).

[1.5.1] - 2021-11-03

Fixed

Certificate.multiProof setter fixed.
Fixed multiproof getting added even if certificate.create() is being called with no args or all the fields

[1.5.0] - 2021-10-29

Added

Added t2lib.Utils.sha256() function to calculate sha256 hash of given data.
Added 'target' member to certificates. it's the ID of the account whose data are getting certified.
Added delegations.
client.accountData() now also accepts a list of data keys.

Fixed

Fixed issue where subsequent calls to account.generate() didn't properly clear the previous value therefore didn't produce a valid signature.

[1.4.7] - 2021-10-21

Changed

Changed library used for sha256 generation in certificates. Certificates created with previous versions cannot be verified successfully by this version and vice versa.
