* Add compatibility tests to CI * Increase timeout to 60s Some of the aggregator tests are running just over 30 seconds when testing on Windows. Bump this to allow for it. * Remove cache setup jobs Having a unified job setup the cache when none exists so packages are only downloaded once is ideal, but these steps are taking too long. In some situations they are doubling the run time. Remove them and prefer to have multiple downloads when dependencies change. * Add changes to changelog * Remove mod-download target from Makefile Unused now that the cache jobs are removed. * Add compatibility testing table to changelog * Add change about precommit to changelog * Update README * Correct examples target in lint job

OpenTelemetry-Go
The Go OpenTelemetry implementation.
Project Status
Warning: this project is currently in a pre-GA phase. Backwards incompatible changes may be introduced in subsequent minor version releases as we work to track the evolving OpenTelemetry specification and user feedback.
Our progress towards a GA release candidate is tracked in this project board. This release candidate will follow semantic versioning and will be released with a major version greater than zero.
Progress and status specific to this repository is tracked in our local project boards and milestones.
Project versioning information and stability guarantees can be found in the versioning documentation.

Getting Started
You can find a getting started guide on opentelemetry.io.
OpenTelemetry's goal is to provide a single set of APIs to capture distributed traces and metrics from your application and send them to an observability platform. This project allows you to do just that for applications written in Go. There are two steps to this process: instrument your application, and configure an exporter.
Instrumentation
To start capturing distributed traces and metric events from your application it first needs to be instrumented. The easiest way to do this is by using an instrumentation library for your code. Be sure to check out the officially supported instrumentation libraries.
If you need to extend the telemetry an instrumentation library provides or want to build your own instrumentation for your application directly you will need to use the go.opentelemetry.io/otel/api package. The included examples are a good way to see some practical uses of this process.
Export
Now that your application is instrumented to collect telemetry, it needs an export pipeline to send that telemetry to an observability platform.
You can find officially supported exporters here and in the companion contrib repository. Additionally, there are many vendor specific or 3rd party exporters for OpenTelemetry. These exporters are broken down by trace and metric support.
