Week of October 5, 2026

What shipped

Why it matters

This week focused on making generated component code and configuration more predictable. Builders can now control which resource detectors end up in a distribution, mdatagen gained sharper opt-outs and deprecation metadata, and a versioned-metrics bug was fixed so both migration gates enabled together emit only the latest attributes. Together these changes reduce surprises for anyone generating or maintaining Collector components.

Post for X

This week in the Collector: builder config for omitting resource detectors, statusutil as a submodule, mdatagen deprecation metadata and sending_queue opt-outs, a versioned-metrics gate fix, and omitempty corrections in ServerConfig. Check the release notes for details.

Post for LinkedIn

This week in the OpenTelemetry Collector repository: the builder can now omit resource detectors that are not configured through it, and internal statusutil became a submodule with real resolvable module versions. mdatagen gained structured deprecation metadata for config properties, a sending_queue opt-out, a go_struct.custom_default knob, and a rename of x-customType to go_struct.type. We also fixed a versioned-metrics issue where both migration gates enabled emitted both legacy and latest attributes, and corrected omitempty handling on generated config fields and confighttp ServerConfig. See the individual pull requests for full details.

Week of September 28, 2026

What shipped

Why it matters

This week addresses critical issues in batch splitting that could lose telemetry data, fixes hash collisions in xhash, and significantly improves performance of metric recording and batch processing. The release includes important breaking changes to processor tests and configuration that users should be aware of.

Changelog entry

Post for X

V1.68.0/v0.162.0 released. Fixed batch splitting to drop only oversized items instead of entire batches, optimized metric recording from O(n²) to O, resolved xhash collisions. Includes breaking changes to processor lifecycle tests.

Post for LinkedIn

OpenTelemetry Collector v1.68.0/v0.162.0 is now available. This release includes critical fixes for batch splitting that prevent data loss when individual items exceed size limits, performance improvements to metric recording that reduce complexity from O(n²) to O, and resolution of hash collisions in xhash. Users should review the breaking changes to generated processor lifecycle tests and configuration before upgrading.

Week of September 21, 2026

What shipped

Why it matters

Bug fixes in error handling and performance improvements in hashing reduce operational issues and improve efficiency. New metrics and observability features help users monitor the collector's behavior, while tooling improvements and naming standardization make the codebase more maintainable and easier to use.

Weekly digest: Fixed otlphttp status codes, added memorylimiter refused requests metric, renamed queuebatch processor, improved map hashing from O(n²) to linear, added exporter span attributes, and enhanced mdatagen tooling.

Post for LinkedIn

This week in opentelemetry-collector: HTTP error handling now returns correct status codes, observability improved with refused request metrics, processor naming standardized, hashing performance optimized from O(n²) to linear, exporter spans enriched with metadata, and configuration generation enhanced for private fields and context propagation testing.

Week of September 14, 2026

What shipped

Why it matters

Version 1.67.0/v0.161.0 brings breaking changes for pkg/pprofile and scraperhelper/controller that users need to address during upgrades. Performance improvements to profile dictionary merging and deep-copy fixes address correctness issues in data handling. Several mdatagen enhancements improve configuration generation and validation across the collector.
