chore: prepare next release

[otelbot-js]

Stable SDK (./CHANGELOG.md)

2.5.1

🐛 Bug Fixes

• fix(opentelemetry-sdk-node): the custom value from env variable for service.instance.id should take priority over random uuid as backup #6345 @maryliag

🏠 Internal

• perf(sdk-trace-base): use Uint8Array for browser RandomIdGenerator #6209 @overbalance
• test(sdk-trace-base): remove obsolete TypeScript and platform workarounds #6327 @overbalance
• fix(example-web): update Docker config and deps for collector #6342 @overbalance
• perf(sdk-trace-base): optimize setAttribute performance #6283 @AbhiPrasad
• refactor(core): remove unnecessary closure in _export() #6360 @cjihrig

Experimental (./experimental/CHANGELOG.md)

0.212.0

💥 Breaking Changes

• feat(sdk-logs)!: move environment variable configuration to @opentelemetry/sdk-node #6325 @pichlermarc
  • (user-facing): environment variable configuration is no longer applied automatically when instantiating SDK components
    (LoggerProvider, BatchLogRecordProcessor) directly from @opentelemetry/sdk-logs. Please migrate to using
    NodeSDK from @opentelemetry/sdk-node to get automatic environment variable configuration.

🚀 Features

• feat(configuration): add Prometheus exporter support #6400 @MikeGoldsmith

• feat(sampler-composite): add ComposableAnnotatingSampler and ComposableRuleBasedSampler #6305 @trentm

• feat(configuration): parse config for rc 3 #6304 @maryliag

• feat(instrumentation): use the internals: true option with import-in-the-middle hook, allowing instrumentations to hook internal files in ES modules #6344 @trentm

🐛 Bug Fixes

• fix(configuration): remove default propagator initialization #6399 @MikeGoldsmith
• fix(instrumentation-fetch): preserve Response.url, type, and redirected properties #6243 @AnubhavPurohit691
  • The fetch instrumentation now preserves the read-only url, type, and redirected properties from the original Response object when wrapping it with a Proxy. This fixes issues where code relying on these properties (e.g., CORS type detection) would fail with instrumented fetch.
• fix(exporter-prometheus): add missing @opentelemetry/semantic-conventions dependency #6330 @omizha
• fix(otlp-transformer): correctly handle Uint8Array attribute values when serializing to JSON #6348 @pichlermarc
• fix(otlp-exporter-base): fix unwanted instrumentation of the fetch exports when context is not propagated #6353 @david-luna

🏠 Internal

• perf(otlp-transformer): optimize toAnyValue performance #6287 @AbhiPrasad
