--- title: Language and Library Versions for Profiler Features description: Datadog, the leading service for cloud-scale monitoring. breadcrumbs: >- Docs > Continuous Profiler > Enabling the Profiler > Language and Library Versions for Profiler Features --- # Language and Library Versions for Profiler Features The following tables summarize the features available for each language runtime. - **Minimum versions** are required to access at least one feature. If you have an earlier version, profiling is not available. - **Feature-complete versions** give you access to **all** supported features. It's usually best if you update to the latest version of all SDKs. {% alert level="info" %} For more details, click the language heading in any table to go that language's setup page. {% /alert %} ## Runtime and SDK versions{% #runtime-and-sdk-versions %} To use the Datadog Profiler, use at least the minimum versions summarized in the following table. For specific profile type availability by version, see Profile types. | [Java](https://docs.datadoghq.com/profiler/enabling/java.md) | [Python](https://docs.datadoghq.com/profiler/enabling/python.md) | [Go](https://docs.datadoghq.com/profiler/enabling/go.md) | [Ruby](https://docs.datadoghq.com/profiler/enabling/ruby.md) | [Node.js](https://docs.datadoghq.com/profiler/enabling/nodejs.md) | [.NET](https://docs.datadoghq.com/profiler/enabling/dotnet.md) | [PHP](https://docs.datadoghq.com/profiler/enabling/php.md) | [Rust/C/C++](https://docs.datadoghq.com/profiler/enabling/ddprof.md) | | ------------------------------------------------------------ | --------------------------------------------------------------------------------- | --------------------------------------------------------- | ------------------------------------------------------------- | ----------------------------------------------------------------- | -------------------------------------------------------------- | ----------------------------------------------------------------------- | -------------------------------------------------------------------- | | **Minimum runtime version** | [JDK 8+](https://docs.datadoghq.com/profiler/enabling/java.md#requirements) | Python 2.7+ | [previous major Go release](https://go.dev/doc/devel/release) | Ruby 2.5+ | Node.js 18+ | .NET Core 2.1+, .NET 5+, .NET Framework 4.6.1+ | PHP 7.1+ | | **Feature-complete runtime version** | [JDK 11+](https://docs.datadoghq.com/profiler/enabling/java.md#requirements) | Python 3.6+ | [latest major Go release](https://go.dev/doc/devel/release) | Ruby 3.2+ | Node.js 18+ | .NET 7+ | PHP 8.0+ | | **Feature-complete SDK version** | [latest](https://github.com/DataDog/dd-trace-java/releases) | [latest](https://github.com/DataDog/dd-trace-py/releases) | [latest](https://github.com/DataDog/dd-trace-go/releases) | [latest](https://github.com/DataDog/dd-trace-rb/releases) | [latest](https://github.com/DataDog/dd-trace-js/releases) | [latest](https://github.com/DataDog/dd-trace-dotnet/releases) | [latest](https://github.com/DataDog/dd-trace-php/releases) | [latest](https://github.com/DataDog/ddprof/releases) | ## Profile types{% #profile-types %} The following table shows profile type availability by language.
