v1.36.0

This version comes with the Application Security (AppSec) public beta which includes a broader security coverage of HTTP servers, now also extended to gRPC servers. It is powered by new security rules that allow monitoring the OWASP Top 10 attack attempts, such as SQL injections, Log4Shell and Server-Side Request Forgeries.

It also includes many APM tracing improvements, along with a fix for a regression introduced in v1.35.0.

1.30.0

This change comes packed with features and new integrations thanks to all the nice contributions, along with a few fixes.

Upgrades

• ⚠️ Users of the profiler that call profiler.WithAPIKey() or set a DD_API_KEY environment variable will see a change in behaviour which could result in breaking their profiling integration. Profiles will now be uploaded through the agent running on localhost:8126. If you don't have an agent running there, please use profiler.WithAgentAddr() or the appropriate environment variables to configure the location of the agent. This commit has more details on the exact changes.
