1.2.10

Because of dependency issues in OTel, you might get conflicting versions of io.opentelemetry:opentelemetry-api that your build tool should be able to deal with and resolve the higher version but here are the details in case you want to double-check it:
Micrometer depends on io.opentelemetry.instrumentation:opentelemetry-instrumentation-bom-alpha:1.31.0-alpha which brings in io.opentelemetry:opentelemetry-api:1.31.0 (through io.opentelemetry:opentelemetry-bom:1.31.0) and io.opentelemetry.semconv:opentelemetry-semconv:1.21.0-alpha. But io.opentelemetry.semconv:opentelemetry-semconv:1.21.0-alpha brings in io.opentelemetry:opentelemetry-api:1.29.0.

So in OTel's dependency tree both 1.29.0 and 1.31.0 of io.opentelemetry:opentelemetry-api are present, see: #819.
