* fix(sampler-jaeger-remote): fixes an issue where package could emit unhandled promise rejections @Just-Sieb
* fix(otlp-grpc-exporter-base): default compression to `'none'` if env vars `OTEL_EXPORTER_OTLP_TRACES_COMPRESSION` and `OTEL_EXPORTER_OTLP_COMPRESSION` are falsy @sjvans
* feat(exporter-*-otlp-*)!: rewrite exporter config logic for testability [#4971](https://github.com/open-telemetry/opentelemetry-js/pull/4971) @pichlermarc
* (user-facing) `getDefaultUrl` was intended for internal use has been removed from all exporters
* (user-facing) `getUrlFromConfig` was intended for internal use and has been removed from all exporters
* (user-facing) `hostname` was intended for internal use and has been removed from all exporters
* (user-facing) `url` was intended for internal use and has been removed from all exporters
* (user-facing) `timeoutMillis` was intended for internal use and has been removed from all exporters
* (user-facing) `onInit` was intended for internal use and has been removed from all exporters
* fix(exporter-*-otlp-*): fixes a bug where signal-specific environment variables would not be applied and the trace-specific one was used instead [#4971](https://github.com/open-telemetry/opentelemetry-js/pull/4971) @pichlermarc
* Fixes:
* `OTEL_EXPORTER_OTLP_METRICS_COMPRESSION`
* `OTEL_EXPORTER_OTLP_LOGS_COMPRESSION`
* `OTEL_EXPORTER_OTLP_METRICS_CLIENT_CERTIFICATE`
* `OTEL_EXPORTER_OTLP_LOGS_CLIENT_CERTIFICATE`
* `OTEL_EXPORTER_OTLP_METRICS_CLIENT_KEY`
* `OTEL_EXPORTER_OTLP_LOGS_CLIENT_KEY`
* `OTEL_EXPORTER_OTLP_METRICS_INSECURE`
* `OTEL_EXPORTER_OTLP_LOGS_INSECURE`
* feat(otlp-exporter-base)!: do not export functions that are intended for internal use [#4971](https://github.com/open-telemetry/opentelemetry-js/pull/4971) @pichlermarc
* Drops the following functions and types that were intended for internal use from the package exports:
* `parseHeaders`
* `appendResourcePathToUrl`
* `appendResourcePathToUrlIfNeeded`
* `configureExporterTimeout`
* `invalidTimeout`
