<blockquote>
<h2>v1.21.0 / 2025-02-19</h2>
<p>:warning: This release contains potential breaking change if you
upgrade <code>github.com/prometheus/common</code> to 0.62+ together with
client_golang (and depend on the strict, legacy validation for the label
names). New common version <a
href="https://redirect.github.com/prometheus/common/pull/724">changes
<code>model.NameValidationScheme</code> global variable</a>, which
relaxes the validation of label names and metric name, allowing all
UTF-8 characters. Typically, this should not break any user, unless your
test or usage expects strict certain names to panic/fail on
client_golang metric registration, gathering or scrape. In case of
problems change <code>model.NameValidationScheme</code> to old
<code>model.LegacyValidation</code> value in your project
<code>init</code> function. ⚠️</p>
<ul>
<li>[BUGFIX] gocollector: Fix help message for runtime/metric metrics.
<a
href="https://redirect.github.com/prometheus/client_golang/issues/1583">#1583</a></li>
<li>[BUGFIX] prometheus: Fix <code>Desc.String()</code> method for no
labels case. <a
href="https://redirect.github.com/prometheus/client_golang/issues/1687">#1687</a></li>
<li>[PERF] prometheus: Optimize popular
<code>prometheus.BuildFQName</code> function; now up to 30% faster. <a
href="https://redirect.github.com/prometheus/client_golang/issues/1665">#1665</a></li>
<li>[PERF] prometheus: Optimize <code>Inc</code>, <code>Add</code> and
<code>Observe</code> cumulative metrics; now up to 50% faster under high
concurrent contention. <a
href="https://redirect.github.com/prometheus/client_golang/issues/1661">#1661</a></li>
<li>[CHANGE] Upgrade prometheus/common to 0.62.0 which changes
<code>model.NameValidationScheme</code> global variable. <a
href="https://redirect.github.com/prometheus/client_golang/issues/1712">#1712</a></li>
<li>[CHANGE] Add support for Go 1.23. <a
href="https://redirect.github.com/prometheus/client_golang/issues/1602">#1602</a></li>
<li>[FEATURE] process_collector: Add support for Darwin systems. <a
href="https://redirect.github.com/prometheus/client_golang/issues/1600">#1600</a>
<a

<a
href="https://redirect.github.com/prometheus/client_golang/issues/1715">#1715</a></li>
<li>[FEATURE] api: Add ability to invoke
<code>CloseIdleConnections</code> on api.Client using
<code>api.Client.(CloseIdler).CloseIdleConnections()</code> casting. <a
href="https://redirect.github.com/prometheus/client_golang/issues/1513">#1513</a></li>
<li>[FEATURE] promhttp: Add
<code>promhttp.HandlerOpts.EnableOpenMetricsTextCreatedSamples</code>
option to create OpenMetrics _created lines. Not recommended unless you
want to use opt-in Created Timestamp feature. Community works on
OpenMetrics 2.0 format that should make those lines obsolete (they
increase cardinality significantly). <a
href="https://redirect.github.com/prometheus/client_golang/issues/1408">#1408</a></li>
<li>[FEATURE] prometheus: Add <code>NewConstNativeHistogram</code>
function. <a
