For notes on SDK versions and changes, see the [change log](#change-log).

## Operating systems [#os]

Integrations built with the SDK can be compiled for either Linux or Windows operating systems.

## Data and file specifications [#data-specs]

Infrastructure on-host integrations can be created with any programming language, as long as they adhere to the [data and file specifications](https://docs.newrelic.com/docs/infrastructure/integrations-sdk/get-started/create-activate-infrastructure-integration).

| 1.13.0 or higher                           | Changes to integration protocol (v4), including support to dynamically register entities in New Relic and send dimensional metrics.                                                               New metric types. See [SDK v4 release notes](https://github.com/newrelic/infra-integrations-sdk/releases/tag/v4.0.0).                                                                                                                                                                                                                                                                                                          |
| 1.0.888 or higher                          | Changes to JSON format, including support for multiple entities. The new JSON format is referred to as protocol `2` (described in [JSON output](https://docs.newrelic.com/docs/integrations/integrations-sdk/file-specifications/integration-executable-file-specifications) documentation and also used in the [definition file](https://docs.newrelic.com/docs/integrations/integrations-sdk/file-specifications/integration-definition-file-specifications#def-header)). Uses newer set of Go language build tools (referenced as [GoSDK v3](https://github.com/newrelic/infra-integrations-sdk/blob/master/docs/v2tov3.md)). |
| 1.0.726 (for Linux); 1.0.775 (for Windows) | Uses JSON protocol `1` (described in [JSON output](https://docs.newrelic.com/docs/integrations/integrations-sdk/file-specifications/integration-executable-file-specifications) documentation and also used in the [definition file](https://docs.newrelic.com/docs/integrations/integrations-sdk/file-specifications/integration-definition-file-specifications#def-header)). Uses older set of Go language build tools (referenced as [GoSDK v2](https://github.com/newrelic/infra-integrations-sdk/blob/master/docs/v2tov3.md)).                                                                                              |

If you've built an integration using the older Go language build tools and wish to update, see [Upgrade from GoSDK v2 to v3](https://github.com/newrelic/infra-integrations-sdk/blob/master/docs/v2tov3.md) and [Upgrade from v3 to v4](http://github.com/newrelic/infra-integrations-sdk/blob/master/docs/v3tov4.md).
