+<details>  
+<summary>Highlights from the upstream Collector changelog</summary>

+
+### 🛑 **Breaking Changes** 🛑
+- **pkg/config/confighttp**: Replace `ServerConfig.Endpoint` with `NetAddr confignet.AddrConfig`, enabling more flexible transport configuration. ([#14187](https://github.com/open-telemetry/opentelemetry-collector/pull/14187), [#8752](https://github.com/open-telemetry/opentelemetry-collector/pull/8752))
+  This change adds "transport" as a configuration option, allowing users to specify
+  different transport protocols (e.g., "tcp", "unix").
+- **pkg/exporterhelper**: Change verbosity level for `otelcol_exporter_queue_batch_send_size` metric to detailed. ([#14278](https://github.com/open-telemetry/opentelemetry-collector/pull/14278))
+- **pkg/service**: Remove deprecated `telemetry.disableHighCardinalityMetrics` feature gate. ([#14373](https://github.com/open-telemetry/opentelemetry-collector/pull/14373))
+- **pkg/service**: Remove deprecated `service.noopTracerProvider` feature gate. ([#14374](https://github.com/open-telemetry/opentelemetry-collector/pull/14374))
+- **processor/tail_sampling**: Deprecated invert decisions disabled by default (use drop policies). ([#44132](https://github.com/open-telemetry/opentelemetry-collector-contrib/pull/44132))
+- **exporter/kafka**: Remove Sarama producer; Franz-go now required. ([#44565](https://github.com/open-telemetry/opentelemetry-collector-contrib/pull/44565))
+- **receiver/kafka**: Remove Sarama consumer and `default_fetch_size`; Franz-go now required. ([#44564](https://github.com/open-telemetry/opentelemetry-collector-contrib/pull/44564))
+- **all**: Add Unix socket support to HTTP server components. [#45308](https://github.com/open-telemetry/opentelemetry-collector-contrib/pull/45308)  
+  HTTP server components (namely receivers) now support listening on Unix domain sockets in addition to TCP addresses, by configuring `transport: unix` and setting `endpoint` to a Unix socket path.  
+  This is a breaking change to the config structs, but is not breaking for end users. Existing YAML configuration options remain unchanged.
+
+---
+
+### 🚩 **Deprecations** 🚩
+- **exporter/otlp_grpc**: Rename `otlp` → `otlp_grpc`; add deprecated alias `otlp`. ([#14403](https://github.com/open-telemetry/opentelemetry-collector/pull/14403))
+- **exporter/otlp_http**: Rename `otlphttp` → `otlp_http`; add deprecated alias `otlphttp`. ([#14396](https://github.com/open-telemetry/opentelemetry-collector/pull/14396))
+
+---
+
+### 💡 **Enhancements** 💡
+- **processor/tail_sampling**: New `decision_wait_after_root_received` option. ([#43876](https://github.com/open-telemetry/opentelemetry-collector-contrib/pull/43876))
+- **processor/k8sattributes**: Bump `semconv` to v1.39.0. ([#45447](https://github.com/open-telemetry/opentelemetry-collector-contrib/pull/45447))
+- **processor/redaction**: Added `sanitize_span_name` and `ignored_key_patterns`. ([#44228](https://github.com/open-telemetry/opentelemetry-collector-contrib/pull/44228).
+- **processor/redaction**: Add ignored_key_patterns configuration option to allow ignoring keys by regex pattern [#44657](https://github.com/open-telemetry/opentelemetry-collector-contrib/pull/44657)).
+- **processor/resourcedetection**: Add optional docker attributes([#44898](https://github.com/open-telemetry/opentelemetry-collector-contrib/pull/44898)
+  Add `container.image.name` and `container.name` optional resource attributes with the docker detector.
+- **receiver/prometheus**: Associate scraped `_created` per OpenMetricsText spec; add troubleshooting/best-practices guide. ([#45291](https://github.com/open-telemetry/opentelemetry-collector-contrib/pull/45291),
+- **receiver/prometheus**: Add comprehensive troubleshooting and best practices guide to Prometheus receiver README [#44925](https://github.com/open-telemetry/opentelemetry-collector-contrib/pull/44925))
+
+---
+
+### 🧰 **Bug Fixes** 🧰
+- **pkg/exporterhelper**: Fix partition batcher refcount. ([#14444](https://github.com/open-telemetry/opentelemetry-collector/pull/14444))
+- **exporter/kafka**: franz-go: Exclude non-produce metrics from kafka_exporter_write_latency and kafka_exporter_latency ([#45258](https://github.com/open-telemetry/opentelemetry-collector-contrib/pull/45258))
+- **pkg/kafka/configkafka**: Fix consumer group rebalance strategy validation [#45268](https://github.com/open-telemetry/opentelemetry-collector-contrib/pull/45268)
+- **pkg/ottl**: Fix numeric parsing to correctly handle signed numbers in math expressions. [#45222](https://github.com/open-telemetry/opentelemetry-collector-contrib/pull/45222)  
+  The OTTL math expression parser did not correctly handle unary signs for plus and minus. Expressions like 3-5 would not parse correctly without inserting spaces to make it 3 - 5. This change moves the sign handling out of the lexer and into the parser.
+- **pkg/ottl**: Handle floating constants with decimal point but no fraction. [#45222](https://github.com/open-telemetry/opentelemetry-collector-contrib/pull/45222)  
+  Floating point constants that had a decimal point but no fractional digits (e.g., "3.") were not handled properly and could crash the parser. These are now parsed as valid floating point numbers.
+- **pkg/stanza**: Fix Windows UNC network path handling in filelog receiver [#44401](https://github.com/open-telemetry/opentelemetry-collector-contrib/pull/44401)  
+  The filelog receiver now correctly handles Windows UNC network paths (e.g., \\server\share\logs*.log). Previously, the receiver could list files from network shares but failed to open them due to path corruption during normalization. This fix converts UNC paths to Windows extended-length format (\\?\UNC\server\share\path) which is more reliable and not affected by filepath.Clean() issues.
+- **pkg/stanza**: Ensure container parser respects the if condition and on_error settings when format detection fails [#41508](https://github.com/open-telemetry/opentelemetry-collector-contrib/pull/41508)
+- **processor/resourcedetection**:  Prevent the resource detection processor from panicking when detectors return a zero-valued pdata resource.([#41934](https://github.com/open-telemetry/opentelemetry-collector-contrib/pull/41934))
+- **processor/resourcedetection**: Fix nil pointer panic when HTTP client creation fails in Start method. ([#45220](https://github.com/open-telemetry/opentelemetry-collector-contrib/pull/45220))
