🛑 Breaking changes 🛑

• bug_fix: Implement encoding.BinaryMarshaler interface to prevent configopaque -> []byte -> string conversions from leaking the value (#9279)

• configopaque: configopaque.String implements fmt.Stringer and fmt.GoStringer, outputting [REDACTED] when formatted with the %s, %q or %#v verbs(#9213) This may break applications that rely on the previous behavior of opaque strings withfmt.Sprintfto e.g. build URLs or headers. Explicitly cast the opaque string to a string before using it infmt.Sprintf` to restore the previous behavior.

💡 Enhancements 💡

• pdata: Introduce API to control pdata mutability (#6794) This change introduces new API pdata methods to control the mutability:
  • p[metric|trace|log].[Metrics|Traces|Logs].MarkReadOnly() - marks the pdata as read-only. Any subsequent mutations will result in a panic.
  • p[metric|trace|log].[Metrics|Traces|Logs].IsReadOnly() - returns true if the pdata is marked as read-only. Currently, all the data is kept mutable. This API will be used by fanout consumer in the following releases.
