(<code>service_name</code>) in <code>target_info</code> when both
<code>without_type_suffix</code> and <code>without_units</code> are set.
Use <code>NoTranslation</code> instead of
<code>UnderscoreEscapingWithoutSuffixes</code> to preserve dot-style
label names while still suppressing metric name suffixes. (<a
href="https://redirect.github.com/open-telemetry/opentelemetry-go-contrib/issues/8763">#8763</a>)</li>
<li>Limit the request body size at 1MB in

<code>host</code> resource detector in
<code>go.opentelemetry.io/contrib/otelconf</code>. (<a
href="https://redirect.github.com/open-telemetry/opentelemetry-go-contrib/issues/8581">#8581</a>)</li>
</ul>
<h2>Deprecated</h2>
<ul>
<li>Deprecate <code>OTEL_EXPERIMENTAL_CONFIG_FILE</code> in favour of
<code>OTEL_CONFIG_FILE</code> in
