For example, an SDK `3.1.x` release does not correspond to Gateway API docs `v1.6`. ## Current stable releases Use the version shown for your client and review its migration requirements before upgrading. | Client | Current stable | Install or download | Release notes | | - | - | - | - | | Node.js | `3.1.0` | `npm install @uqpay/sdk@3.1.0` | [Node.js changelog for v3.1.0](https://github.com/uqpay/uqpay-node/blob/e282972f36919d3d14f6bd8398ccf218bc481b57/CHANGELOG.md#310) | | Python | `3.1.0` | `pip install --upgrade uqpay==3.1.0` | [Python changelog for v3.1.0](https://github.com/uqpay/uqpay-sdk-python/blob/2ee2efec53efa2c73be790298e462164423bad4f/CHANGELOG.md#310) | | Go | `3.1.0` | `go get github.com/uqpay/uqpay-sdk-go/v3@v3.1.0 && go mod tidy` | [Go v3.1.0 release](https://github.com/uqpay/uqpay-sdk-go/releases/tag/v3.1.0) | | Java | `3.1.0` | [Download the v3.1.0 release JAR](https://github.com/uqpay/uqpay-sdk-java/releases/tag/v3.1.0) | [Java v3.1.0 release](https://github.com/uqpay/uqpay-sdk-java/releases/tag/v3.1.0) | | CLI | `3.1.0` | `npm install -g @uqpay/cli@3.1.0` | [CLI changelog for v3.1.0](https://github.com/uqpay/uqpay-cli/blob/682795c8a5b6d75bba3b42268faca127622894cb/CHANGELOG.md#310) | > [!WARNING] > > The Java SDK is distributed as a thin JAR through GitHub Releases. It is not published to Maven Central, and your application must declare its runtime dependencies. ## Release history ### SDK and CLI v3.1.0 Version `3.1.0` aligns PIN management, RFI answers, beneficiary checks, simulated deposits, and response/Webhook models across Node.js, Python, Go, Java, and CLI. It retains the full functionality originally published as 4.0.0 under a corrected version number. Review the migration requirements when upgrading from 3.0.0. | Area | Migration requirement | | - | - | | PIN management | On the unified PIN endpoint, omitted `type` means initial `SET`. Use explicit `RESET` without the current PIN, or `UPDATE` with six-digit `old_pin`. An accepted request is not a completed PIN operation; query `card_order_id`. | | RFI | Send the full prefixed `rfi_id`. Request attachments are uploaded file IDs; response attachments are file-detail objects. Update code using typed response models. | | Simulated deposits | Supply `account_id` explicitly. This API is Sandbox-only. | | Beneficiary checks | Supply at least one non-empty `account_number` or `iban`. | | Go | Use `/v3`; existing 3.0.0 integrations keep their import paths. Change `/v4` imports to `/v3` if applicable, then run `go mod tidy`. | | Java | Continue using the GitHub Release JAR with its runtime dependencies; Maven Central is not available. | See the versioned migration notes for [Node.js](https://github.com/uqpay/uqpay-node/blob/e282972f36919d3d14f6bd8398ccf218bc481b57/CONTRACT_ALIGNMENT.md), [Python](https://github.com/uqpay/uqpay-sdk-python/blob/2ee2efec53efa2c73be790298e462164423bad4f/CONTRACT_ALIGNMENT.md), [Go](https://github.com/uqpay/uqpay-sdk-go/blob/f631f53fcf657b1d37ec9f1e1389f0c7a9337d98/CONTRACT_ALIGNMENT.md), [Java](https://github.com/uqpay/uqpay-sdk-java/blob/af741966c9a1e28e74783acd0dfb6f9857278c51/CONTRACT_ALIGNMENT.md), and [CLI](https://github.com/uqpay/uqpay-cli/blob/682795c8a5b6d75bba3b42268faca127622894cb/CONTRACT_ALIGNMENT.md). This release does not add the newer pre-authorization capture request fields or CARD/Mastercard Send beneficiary types. Check the relevant API reference when integrating those capabilities. ### SDK and CLI v3.0.0 Version `3.0.0` aligns the typed `COMPANY` Create SubAccount request models with the Account Center contract effective on 2026-09-17. The affected representative and `business_details` fields are required, and the removed company `account_purpose` values are no longer accepted. The Go module and import path now use `github.com/uqpay/uqpay-sdk-go/v3`. See the [2026-09-17 platform changelog entry](https://developers-sandbox.uqpaytech.com/docs/changelog#2026-09-17) for the affected fields, supported values, and migration requirements. ### SDK and CLI v2.1.0 Version `2.1.0` lets `COMPANY` Create SubAccount requests omit `ownership_details.representatives[].date_of_birth`. When supplied, the value must remain a `YYYY-MM-DD` date. `INDIVIDUAL` requests still require `individual_info.date_of_birth`. This is a compatible change. Existing integrations that send a valid representative date of birth do not need to change. See the [2026-08-26 platform changelog entry](https://developers-sandbox.uqpaytech.com/docs/changelog#2026-08-26) for the API contract. ### SDK and CLI v2.0.0 Version `2.0.0` adds support for the Virtual Account application contract across Node.js, Python, Go, Java, and CLI. For Go, the module and import path now use `github.com/uqpay/uqpay-sdk-go/v2`. See the [2026-09-03 platform changelog entry](https://developers-sandbox.uqpaytech.com/docs/changelog#2026-09-03) for upgrade commands and the Virtual Account migration path. ### Go v1.2.1 Go `v1.2.1` adds support for PGP authorization decisions. This SDK release does not change the Gateway API documentation version. See the [Go v1.2.1 release notes](https://github.com/uqpay/uqpay-sdk-go/releases/tag/v1.2.1) for details. ### SDK and CLI v1.2.0 Version `1.2.0` was the first `1.x` release available across Node.js, Python, Go, Java, and CLI. See the [2026-08-04 platform changelog entry](https://developers-sandbox.uqpaytech.com/docs/changelog#2026-08-04) for upgrade commands, runtime requirements, and the original announcement. ## Where changes are recorded * Use the release-notes link in the table for changes specific to one SDK or the CLI. * Use the [Platform and Gateway API changelog](https://developers-sandbox.uqpaytech.com/docs/changelog) for API, platform, and documentation changes.
