+### Added
+
+- Support `OTEL_EXPORTER_OTLP_LOGS_INSECURE` and `OTEL_EXPORTER_OTLP_INSECURE` environments in `go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploggrpc`. (#5739)
+- The `WithResource` option for `NewMeterProvider` now merges the provided resources with the ones from environment variables. (#5773)
+- The `WithResource` option for `NewLoggerProvider` now merges the provided resources with the ones from environment variables. (#5773)
+- Add UTF-8 support to `go.opentelemetry.io/otel/exporters/prometheus`. (#5755)
+
+### Fixed
+
+- Fix memory leak in the global `MeterProvider` when identical instruments are repeatedly created. (#5754)
+- Fix panic on instruments creation when setting meter provider. (#5758)
+- Fix an issue where `SetMeterProvider` in `go.opentelemetry.io/otel` might miss the delegation for instruments and registries. (#5780)
+
+### Removed
+
+- Drop support for [Go 1.21]. (#5736, #5740, #5800)
