1.3.4

Because of issues with OTel dependencies, this release effectively downgrades

• io.opentelemetry.instrumentation:opentelemetry-instrumentation-api-semconv from 1.33.5-alpha to 1.33.3-alpha
• io.opentelemetry:opentelemetry-api from 1.40.0 to 1.38.0

This is because we usually don't upgrade minor versions in patch releases but since OTel does, we unintentionally upgraded io.opentelemetry:opentelemetry-api from 1.38.0 to 1.40.0 (minor version bump) in earlier patch releases since we upgraded io.opentelemetry.instrumentation:opentelemetry-instrumentation-api-semconv from 1.33.3-alpha to 1.33.5-alpha (patch version bump). A minor version bump in a patch release can be unexpected so this release restores the same minor versions of OTel that 1.3.0 used, see: #819.

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.
