Version 1.7.1

This is a patch release on the previous 1.7.0 release, fixing the three issues below. If you are not affected by these, you do not need to update.

🛠️ Bug fixes

• Java agent 1.7.0 fails with prometheus exporter (#4460)
• Android regression in okhttp instrumentation in 1.7.0 (#4452)
• Remove unshaded javax.annotation classes from bootstrap class loader (#4454)

Version 1.7.0

Note: with this release, the -all artifact has been removed and the default artifact (with no classifier) is now the go-to artifact that contains the exporters. If you want an artifact with no exporters, there is a new -slim artifact that is published to maven central. The -all artifact is still attached to this release below (it has the same content as the default artifact), but will no longer be attached to the releases starting from v1.8.0.

This release requires the use of OpenTelemetry Java SDK 1.7.0.

Note that all artifacts other than io.opentelemetry.javaagent:opentelemetry-javaagent have the -alpha suffix attached to their version number, reflecting that they are still alpha quality and will continue to have breaking changes. Please see the VERSIONING.md for more details.
