Known issues

After a very large trace, traces may stop being reported. If your application produces very large traces, stay on 0.72.0 or wait for 0.75.0

Breaking Changes

Constants from datadog.trace.api.Config #2381 are no longer available. This should only potentially impact dd-trace-ot users who are using these deprecated string literals.
MutableSpan.isError() returns primitive boolean instead of Boolean #2356. This change is binary incompatible with prior releases. Manual instrumentation calling this method will need to be rebuilt against the new version.
