Breaking Changes

●Issue #1

Code attributes for spans have been updated to use stable names: `code.function` is now `code.function.name`, `code.lineno` is now `code.line.number`, and `code.filepath` is now `code.file.path`. Users relying on the old attribute names for instrumentation or processing must update their code to use the new stable names.

Migration Steps

  1. 1
    Update code that accesses span code attributes to use the new stable names: `code.function.name`, `code.line.number`, and `code.file.path` instead of the previous names.

Release Summary

This release stabilizes code attribute names in the SDK, fixes several bugs related to HTTP connections and log serialization, and updates semantic conventions.
