Version 1.26.0

[github-actions[bot]]

This release represents the release candidate ("RC") release for the Logs Bridge API / SDK. In the next release (1.27.0), opentelemetry-api-logs will be merged into opentelemetry-api, opentelemetry-sdk-logs will be marked as stable, opentelemetry-exporter-otlp-logs will be merged into opentelemetry-exporter-otlp, opentelemetry-sdk-logs-testing will be merged into opentelemetry-sdk-testing, opentelemetry-sdk-extension-autoconfigure will enable otlp log exporter by default (i.e. otel.logs.exporter=otlp). For more details, see tracking issue #5340. NOTE: reminder that the Logs Bridge API is not meant for end users. Log appenders use the API to bridge logs from existing log frameworks (e.g. JUL, Log4j, SLf4J, Logback) into OpenTelemetry. Users configure the Log SDK to dictate how logs are processed and exported.

opentelemetry-opentracing-shim is now stable!
