#### ⚠️ Breaking changes ⚠️

- Label names that start with a single Underscore (`_`) character are no
longer prefixed with the word `key` during translation. Folks who depend
on such behavior can re-enable it by setting
`LabelNamer.UnderscoreLabelSanitization = true`.
[#&#8203;55](https://redirect.github.com/prometheus/otlptranslator/pull/55)
- Labels that have multiple underscores in sequence are now deduplicated
if UTF-8 isn't allowed. Folks who depend on such behavior can re-enable
it by setting `LabelNamer.PreserveMultipleUnderscores = true`. Be aware
that if `UTF8Allowed` is set to true, multiple underscores are preserved
even if `PreserveMultipleUnderscores == false`.
[#&#8203;58](https://redirect.github.com/prometheus/otlptranslator/pull/58)

#### Bug fixes

- Error is returned if the result of a translation is a string
consisting of underscores only.
[#&#8203;56](https://redirect.github.com/prometheus/otlptranslator/pull/56)

#### Performance

- Remove usage of regexp.
[#&#8203;59](https://redirect.github.com/prometheus/otlptranslator/pull/59)
