This release addresses a performance regression introduced in
[#&#8203;1661](https://redirect.github.com/prometheus/client_golang/issues/1661)
-- thanks to all who [reported this
quickly](https://redirect.github.com/prometheus/client_golang/issues/1748):

[@&#8203;kakkoyun](https://redirect.github.com/kakkoyun) 💪🏽. This patch
release also fixes the iOS build.

We will be hardening the release process even further
([#&#8203;1759](https://redirect.github.com/prometheus/client_golang/issues/1759),
[#&#8203;1761](https://redirect.github.com/prometheus/client_golang/issues/1761))
to prevent this in future, sorry for the inconvenience!

The high concurrency optimization is planned to be eventually
reintroduced, however in a much safer manner, potentially in a separate
API.

- \[BUGFIX] prometheus: Revert of `Inc`, `Add` and `Observe` cumulative
metric CAS optimizations

causing regressions on low concurrency cases

⚠️ This release contains potential breaking change if you upgrade
`github.com/prometheus/common` to 0.62+ together with client_golang (and
depend on the strict, legacy validation for the label names). New common
version [changes `model.NameValidationScheme` global
variable](https://redirect.github.com/prometheus/common/pull/724), 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 `model.NameValidationScheme` to old
`model.LegacyValidation` value in your project `init` function.
⚠️

- \[BUGFIX] gocollector: Fix help message for runtime/metric metrics.
[#&#8203;1583](https://redirect.github.com/prometheus/client_golang/issues/1583)
- \[BUGFIX] prometheus: Fix `Desc.String()` method for no labels case.
[#&#8203;1687](https://redirect.github.com/prometheus/client_golang/issues/1687)
- \[PERF] prometheus: Optimize popular `prometheus.BuildFQName`
function; now up to 30% faster.
[#&#8203;1665](https://redirect.github.com/prometheus/client_golang/issues/1665)
- \[PERF] prometheus: Optimize `Inc`, `Add` and `Observe` cumulative
metrics; now up to 50% faster under high concurrent contention.
[#&#8203;1661](https://redirect.github.com/prometheus/client_golang/issues/1661)
- \[CHANGE] Upgrade prometheus/common to 0.62.0 which changes
`model.NameValidationScheme` global variable.
[#&#8203;1712](https://redirect.github.com/prometheus/client_golang/issues/1712)
- \[CHANGE] Add support for Go 1.23.
[#&#8203;1602](https://redirect.github.com/prometheus/client_golang/issues/1602)
- \[FEATURE] process_collector: Add support for Darwin systems.
[#&#8203;1600](https://redirect.github.com/prometheus/client_golang/issues/1600)
[#&#8203;1616](https://redirect.github.com/prometheus/client_golang/issues/1616)

[#&#8203;1675](https://redirect.github.com/prometheus/client_golang/issues/1675)
[#&#8203;1715](https://redirect.github.com/prometheus/client_golang/issues/1715)
- \[FEATURE] api: Add ability to invoke `CloseIdleConnections` on
api.Client using `api.Client.(CloseIdler).CloseIdleConnections()`
casting.
[#&#8203;1513](https://redirect.github.com/prometheus/client_golang/issues/1513)
- \[FEATURE] promhttp: Add
`promhttp.HandlerOpts.EnableOpenMetricsTextCreatedSamples` 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).
[#&#8203;1408](https://redirect.github.com/prometheus/client_golang/issues/1408)
- \[FEATURE] prometheus: Add `NewConstNativeHistogram` function.
[#&#8203;1654](https://redirect.github.com/prometheus/client_golang/issues/1654)
