0.29.0 - 2022-04-11

Added

• The metrics global package was added back into several test files. (#2764)
• The Meter function is added back to the go.opentelemetry.io/otel/metric/global package. This function is a convenience function equivalent to calling global.MeterProvider().Meter(...). (#2750)

Removed

• Removed module the go.opentelemetry.io/otel/sdk/export/metric. Use the go.opentelemetry.io/otel/sdk/metric module instead. (#2720)

Changed

• Don't panic anymore when setting a global MeterProvider to itself. (#2749)
• Upgrade go.opentelemetry.io/proto/otlp in go.opentelemetry.io/otel/exporters/otlp/otlpmetric from v0.12.1 to v0.15.0. This replaces the use of the now deprecated InstrumentationLibrary and InstrumentationLibraryMetrics types and fields in the proto library with the equivalent InstrumentationScope and ScopeMetrics.
