Release v0.48.0

Note

This repo has adopted the OpenTelemetry Collector/Collector-Contrib chloggen process for tracking independent changelogs to Go and Rust code in the repo. This is the first release using this new system. For the moment, we are versioning Go and Rust together with the same version number.

What's Changed (Rust 🦀)

🚀 New components 🚀

• pipeline: Add the journald receiver configuration and factory skeleton. (#2858)
  Adds Linux-only receiver registration, validated source/checkpoint/batch configuration,
  lifecycle metrics, and a process-local source lease. Worker ingestion and checkpoint
  persistence will land in follow-up PRs.

💡 Enhancements 💡

• all: Adopt the chloggen tool for managing changelog entries. (#1423)
• dependencies: Upgrade various Rust dependencies. (#2548, #2637, #2639, #2640, #2707, #2760, #2762, #2800, #2831, #2915, #2921, #2965, #2968, #2976, #2979, #2998, #3081, #3091, #3092, #3113, #3114, #3130, #3133, #3147, #3148, #3150)
• pipeline: Add optional user_agent config field to the Azure Monitor exporter for injecting a custom User-Agent HTTP header on all outgoing requests including heartbeat. (#3137)
• pipeline: Add metric-name filtering (include/exclude with strict or regexp match) to the filter processor. (#2777)
• pipeline: Hardens flow metric config to throw an error if the user attempts to configure a flow metric with an unreachable end node. (#3009)
• pipeline: Add opt-in Linux load average metrics to the host metrics receiver. (#3067)
• pipeline: Improve OTLP performance by avoiding converting to OTAP before counting items. (#2993)
  The perf exporter previously converted every incoming payload into an
  OtapArrowRecords batch solely to call num_items(). For OTLP-bytes payloads
  this Arrow encoding dominated the exporter's CPU (~50%) and could bottleneck
  single-core throughput. It now uses OtapPayload::num_items().
