Changed

• disable default features of tracing-subscriber (#1476)
• allow custom journal fields (#2708)
• Bump MSRV to 1.63 (#2793)
• make level mappings configurable (#2824)

This is a breaking release which changes the format in which span fields are output to journald. Previously, span field names were prefixed with the depth of the span in the current trace tree. However, these prefixes are unnecessary, as journald has built in support for duplicated field names.

See PR #1986 for details on this change.

Changed

• Removed span field prefixes (#1986)
• Renamed S{num}_NAME fields to SPAN_NAME (#1986)

Fixed
