- Breaking: removed legacy pdata functions and updated exemplar/value type APIs, impacting callers from v0.48.0 onward.
- Deprecations: configunmarshaler moved internal, semconv API moved, request Set* methods replaced, metric value type aliases removed, and global featuregate funcs replaced.
- Minor enhancements and bug fixes: improved config map unmarshalling, quieter collector shutdown, and fixes for pdata copying and exporter helper stop behavior.
