[3.2.0] - 2025-08-07

• fix: do not subtract the replica permitted clock drift when calculating the ingress expiry.
• fix: pick the expiry rounding strategy based on the delta, without adding the clock drift to the delta.

• fix: add declaration maps and typescript source code to published packages.
• feat: enables type inference for the arguments and return types of FuncClass.
• feat: enables type inference for the fields of ServiceClass.

• fix: account for clock drift when verifying the certificate freshness, and syncs time with the IC network if the certificate fails the freshness check and the agent’s time is not already synced.
• feat: adds the agent optional field to the CreateCertificateOptions interface, which is used to sync time with the IC network if the certificate fails the freshness check, if provided.
• feat: adds the getTimeDiffMsecs method to the HttpAgent class, which returns the time difference in milliseconds between the IC network clock and the client’s clock.
• feat: adds the hasSyncedTime method to the HttpAgent class, which returns true if the time has been synced at least once with the IC network, false otherwise.
• fix: use the effective canister id to delete the node keys from the local cache.
• docs: add DFINITY Starlight theme to the docs
• feat: adds the disableCertificateTimeVerification optional field to the CanisterStatus.request function argument, which allows you to control the disableTimeVerification option for the internal Certificate.create call.

• fix: override instanceof in Candid IDL types to avoid issues when importing IDL from multiple locations.

[3.0.0] - 2025-07-17

[3.0.0-beta.4] - 2025-07-17

Changed

• chore: replaces ts-node with pnpm dlx tsx for version management scripts
• chore: updates the version script to work with new pnpm workspaces
• feat: removes the watermark checks when checking query responses. Now the agent checks if the node signature is not older than the ingressExpiryInMinutes option (taking into account the clock drift).
• fix: always account for the clock drift when calculating the ingress expiry.
• fix: AuthClient.create’s options now have an additional loginOptions optional parameter, which is merged with the options passed to login when calling it.
• fix: handle BigInt values when instantiating the buffer in lebEncode and slebEncode from @dfinity/candid. As a result, @dfinity/candid now correctly encodes large bigints as Nat values.
• fix: make .ts extension required for all relative imports. This is required to avoid the “Module not found” error when importing the packages in Node.js (ESM).

Added

• feat: Starlight documentation website, with custom plugin for typedoc

[3.0.0-beta.1] - 2025-06-19

Changed

• chore: update @noble/* dependencies
• fix: mark @noble/hashes as a dependency rather than a dev dependency

[3.0.0-beta.0] - 2025-06-17

Changed

• chore!: removes management canister from @dfinity/agent in favor of @dfinity/ic-management

• feat!: changes all @dfinity/candid interfaces to Uint8Array<ArrayBuffer> instead of ArrayBuffer to make the API more consistent.

• feat!: replaces fromHex, toHex, concat utils with bytesToHex, hexToBytes, and concatBytes from @noble/hashes/utils respectively, to take advantage of existing dependencies.

• feat!: changes polling strategy for read_state requests to support presigned requests. By default, read_state requests will create a new signature with a new ingress expiry each time they are made. However, the new preSignReadStateRequest will make one signature and use it for all polling requests. This is useful for hardware wallets or other external signing solutions that make signing cumbersome.

  • pollForResponse now moves strategy, request, and preSignReadStateRequest to the options: PollingOptions object
  • new export: PollingOptions type
  • Actor also includes a pollingOptions object that can be passed to the actor function and will be passed to the pollForResponse method

• feat!: removes the unused defaultAgent global concept and the getDefaultAgent function. The HttpAgent constructor is now the only way to create an agent.

• feat!: removes the ProxyAgent class.

• feat!: removes the following errors in favor of the new AgentError:

  • AgentHTTPResponseError
  • AgentCallError
  • AgentQueryError
  • AgentReadStateError
  • CertificateVerificationError
  • ActorCallError
  • QueryCallRejectedError
  • UpdateCallRejectedError

  The new AgentError error uses the code and kind props to enable a better programmatic error handling.

• feat!: refactors Expiry class to use static factory methods and add JSON serialization/deserialization.

• feat!: makes lookup_path compliant with the IC Interface Specification. Renames the lookup method of the Certificate class into lookup_path, for consistency.

• feat!: removes the lookup_label method from the Certificate class.

• feat!: replaces hash with sha256 from @noble/hashes/sha2 to take advantage of existing dependencies

• chore!: drops support for Node.js v19 or lower, and Node.js v21

• feat: replaces borc and simple-cbor with @dfinity/cbor.

• chore: removes unused bs58check dependency from @dfinity/identity-secp256k1

• fix: AuthClient isAuthenticated now correctly returns false if the delegation chain is invalid; eg: expired session

• feat: introduces the lookup_subtree standalone function and Certificate class method.

• chore: formatting files and changelog

• test: removes backwards compatibility test for Actor with v1 HttpAgent due to breaking interface changes.

• fix: Check subtyping relationship when decoding function or service references

  • This means we now follow the Candid spec more closely, and reduces the risk of calling services with the wrong argument types

• fix: retry requests that fail due to a malformed response body

[2.4.1] - 2025-04-10

Changed

• fix: fixes a bug in Ed25519KeyIdentity toRaw where the output was not an ArrayBuffer
• test: fixes e2e tests for compatibility with dfx 0.26.0 and pocket-ic by querying for the default_effective_canister_id before calling the management canister
• fix: fixes a bug in the Ed25519KeyIdentity verify implementation where the argument order was incorrect
• fix: fixes a bug in the Principal library where the management canister id util was incorrectly importing using fromHex
• feat: change auth-client’s default identity provider url

[2.4.0] - 2025-03-24

Changed

• chore: changes trap e2e test to check for the response “trapping”. Resolves a discrepancy with the replica response introduced in dfx 0.25.1
• fix: Bring Candid decoding of opt types up to Candid spec: In particular, when decoding at an opt type:
  • If the wire type is an opt type, decode its payload at the expected content type (as before).
  • Allow decoding null wire type as IDL value null (i.e. JS []).
  • Allow decoding of value of reserved wire type, defaulting to IDL value null (i.e. JS []).
  • Allow decoding of wider variant type on the wire at narrower expected variant type, provided the decoded value is valid at the expected variant type. Otherwise, default to null (i.e. JS []).
  • Otherwise:
    • If the expected content type is null or reserved or (nested) opt, return IDL value null (i.e. JS []).
    • The expected content type is neither null, reserved or nested opt: allow decoding of the non-optioned value v as opt v (JS [v*]) if compatible with the expected content type; if incompatible, return IDL value null (JS []).

Added

• feat: refactor nonce logic to prioritize options and ensure compatibility with ArrayBuffer and Uint8Array
• test: added e2e test for CanisterStatus requesting a subnet path, as a reference for getting the subnet id of a given canister id

[2.3.0] - 2025-02-07

Added

• shouldFetchRootKey option added to HttpAgent constructor
• ci: adds BOT_APPROVED_FILES config

Changed

• feat: HttpAgent uses anonymous identity to make syncTime call, which can allow readState calls to work beyond 5 minutes

[2.2.1] - 2025-02-07

Changed

• fix: reverts read_state polling expiry changes due to mismatched signature introduced in 2.1.3. Polling will re-use the original request as before, up to the point where the request expires

[2.2.0] - 2024-12-12

Added

• fix: target_canister is used only for install_chunked_code of management canister, complying with internet computer specification

Changed

• chore: pins nanoid dev dependency version to override warning
• chore: Removes warning that users found unhelpful, when a message originates from other sources than the identity provider in AuthClient during authentication.
• chore: fixes typo in DelegationIdentity jsdoc comment
• chore: Removes warning that users found unhelpful, when a message originates from other sources than the identity provider in AuthClient during authentication.

[2.1.3] - 2024-10-23

Added

• feat: allow for setting HttpAgent ingress expiry using ingressExpiryInMinutes option

• feat: improved assertion options for agent errors using prototype, name, and instanceof

Changed

• test: automatically deploys trap canister if it doesn’t exist yet during e2e
• fix: handle v3 traps correctly, pulling the reject_code and message from the certificate in the error response like v2. Example trap error message:

AgentError: Call failed:
  Canister: hbrpn-74aaa-aaaaa-qaaxq-cai
  Method: Throw (update)
  "Request ID": "ae107dfd7c9be168a8ebc122d904900a95e3f15312111d9e0c08f136573c5f13"
  "Error code": "IC0406"
  "Reject code": "4"
  "Reject message": "foo"

• feat: the UpdateCallRejected error now exposes reject_code: ReplicaRejectCode, reject_message: string, and error_code?: string properties directly on the error object.
• fix: recalculates body to use a fresh Expiry when polling for read_state requests. This prevents the request from exceeding the maximum_ingress_expiry when the replica is slow to respond.

• ci: changing token for creating release

Added

• test: adding test for backwards compatibility with actor for v1 agents

Added

• feat: make IdbStorage get/set methods generic
• chore: add context to errors thrown when failing to decode CBOR values.

[0.13.3]

Changed

• New package: @dfinity/bls-verify. This package provides a pure-js implementation of BLS verification using the miracl-core package. This can be used to polyfill BLS verification for agent-js, but it is notably very slow (~3s per verification). Optimization may be possible with a significant refactoring
• adds ability to polyfill bls verification in Certificate
• Auth Client moves key fallback generation to the create method instead of login and makes the \_key non-nullable. This fixes a regression with async window.open behavior in Safari

[0.12.2]

Changed

• Support for the SubtleCrypto interface in @dfinity/identity using the new ECDSAKeyIdentity
• CanisterStatus no longer suppresses rootKey errors
• Readme’s point to https://agent-js.icp.xyz

[0.12.1]

Changed

• Adds inline sourcemaps to packages
• Pulls lint out to a separate job now that Node 12 is failing with latest eslint dependencies
• Adds UTF-8 as an encoding option for CanisterStatus custom paths
• Adds a public method createReadStateRequest that creates the request for readState.
• Add an extra parameter to readState to pass a created request. If this parameter is passed, the method does the request directly without creating a new one.
• Use the createReadStateRequest and the extra parameter when polling for the response to avoid signing requests during polling.
• Adds derivationOrigin to auth-client login to support the ability to login using the identity derived from a different origin. See proposed changes

[0.12.0]

Changed

• Changed the certificate verification interface and fixed its logic. The public constructor is now static and asynchronous. There is no separate verification method, the check is done automatically in the constructor and newly also checks that the delegation is authoritative for the given canister ID, as required by the Internet Computer interface specification.

[0.11.2]

Changed

• Adds a default callback to the IdleManager that will refresh the page after clearing the storage

• Adds a new utility method, canisterStatus, to agent-js. Canister status now allows you to query paths from the canister certificate with a simple interface, using the API from theinterface specification Comes with nicely configured options for

  time, controllers, subnet, module_hash, candid. Additionally, has a utility for reading custom MetaData set using ic-wasm, as well as generic custom paths in the format of ArrayBuffers.

• updates to package.json files for metadata in npm

[0.11.1]

Changed

• Fix for a corner case that could lead to incorrect decoding of record types.

[0.11.0]

Changed

• makeNonce now returns unique values. Previously only the first byte of the nonce was populated.

• Introduces IdleManager to the auth-client. You can now use it to detect when the user has been idle for a configurable amount of time, and then to register callbacks for the sake of logging the user out and prompting re-authentication. See the @dfinity/auth-client Readme for more details

• Reduces the maxTimeToLive default setting from 24 hours to 8

• Versioning tool now sets patch version to 0 for minor version updates, or patch and minor versions to 0 for major version updates

• Removes jest-expect-message, which was making test error messages less useful

• HttpAgent now generates a nonce to ensure that calls are unique by default. If you want to opt out or provide your own nonce logic, you can now pass an option of disableNonce: trueduring the agent initialization.

  If you are currently using agent.addTransform(makeNonceTransform()) , please note that you should remove that logic, or add the disableNonce option to your agent when upgrading.

[0.10.3]

Changed

• Candid now allows optional records to be omitted. See https://github.com/dfinity/agent-js/issues/524
• In auth-client, login onSuccess callback and onError callback now supports async pattern.
• Updates npm dependencies to resolve warnings for typedoc and node-fetch. No runtime dependencies were affected.

[0.10.2]

Changed

• Security enhancement - adds a rewrite for urls to subdomains of

  \*.ic0.app/api

  to

  ic0.app/api

• Improves error messages for when HttpAgent cannot infer fetch implementation

[0.10.1]

Changed

• Fix for the auth-client identity option and added JSDOC comment for the timeToLive option
• Sets the default Internet Identity expiration to 1 day for the authClient, up from 15 minutes
• No longer checks instanceof Principal in @dfinity/agent, which should allow non-identical versions of packages to interoperate, as long as they share the same API

[0.10.0]

Changed

• Adds changelog for agent-js packages
• Buffer and Pipe refactor
  • In previous versions of dfinity packages, we relied on Buffer, a polyfilled version of the Node.js Buffer utility. In a significant refactor, we have removed all cases of this, along with Pipe and the nonstandard Blob packages, in favor of ArrayBuffer, Uint8Array, and DataView
  • Utility methods such as blobToUint8Array have been removed.
  • Interfaces that relied on Buffer and related packages have been updated to accept ArrayBuffer, and the type interfaces are updated to reflect this
• Secp256k1 Support
  • Adds two new exports to @dfinity/identity - Secp256k1KeyIdentity and Secp256k1PublicKey
  • API mirrors the ed25519 components, and relies on the secp256k1 npm package for signing and verification.
