 ### 🛑 Breaking changes 🛑
 
 - (Splunk) `receiver/discovery`: Remove `append_pattern` option from log evaluation statements ([#4583](https://github.com/signalfx/splunk-otel-collector/pull/4583))
   - The matched log message is now set as `discovery.matched_log` entity attributes instead of being appended to 
     the `discovery.message` attribute.
   - The matched log fields like `caller` and `stacktrace` are not sent as attributes anymore.
+- (Contrib) `vcenterreceiver`: Removes vcenter.cluster.name attribute from vcenter.datastore metrics ([#32674](https://github.com/open-telemetry/opentelemetry-collector-contrib/issues/32674))
+  If there were multiple Clusters, Datastore metrics were being repeated under Resources differentiated with a
+  vcenter.cluster.name resource attribute. In the same vein, if there were standalone Hosts, in addition to
+  clusters the metrics would be repeated under a Resource without the vcenter.cluster.name attribute. Now there
+  will only be a single set of metrics for one Datastore (as there should be, as Datastores don't belong to
+  Clusters).
+- (Contrib) `resourcedetectionprocessor`: Move `processor.resourcedetection.hostCPUModelAndFamilyAsString` feature gate to stable. ([#29025](https://github.com/open-telemetry/opentelemetry-collector-contrib/issues/29025))
+- (Contrib) `filelog`, `journald`, `tcp`, `udp`, `syslog`, `windowseventlog` receivers: The internal logger has been changed from `zap.SugaredLogger` to `zap.Logger`. ([#32177](https://github.com/open-telemetry/opentelemetry-collector-contrib/pull/32177))
+  This should not have any meaningful impact on most users but the logging format for some logs may have changed.

   - To skip .NET auto instrumentation, configure the `auto_instrumentation_sdks` option without `dotnet`.
   - `npm` is required to be pre-installed on the node to install the Node.js SDK. Configure the `auto_instrumentation_npm_path` option to specify the path to `npm`.
   - .NET auto instrumentation is currently only supported on amd64/x64_64.
+- (Core) `confmap`: Allow Converters to write logs during startup ([#10135](https://github.com/open-telemetry/opentelemetry-collector/pull/10135))

+- (Contrib) `deltatocumulativeprocessor`: exponential histogram accumulation ([#31340](https://github.com/open-telemetry/opentelemetry-collector-contrib/issues/31340))
+  accumulates exponential histogram datapoints by adding respective bucket counts. also handles downscaling, changing zero-counts, offset adaptions and optional fields
+- (Contrib) `extension/storage/filestorage`: New flag cleanup_on_start for the compaction section (default=false). ([#32863](https://github.com/open-telemetry/opentelemetry-collector-contrib/pull/32863))
+  It will remove all temporary files in the compaction directory (those which start with `tempdb`),
+  temp files will be left if a previous run of the process is killed while compacting.
+- (Contrib) `vcenterreceiver`: Refactors how and when client makes calls in order to provide for faster collection times. ([#31837](https://github.com/open-telemetry/opentelemetry-collector-contrib/issues/31837))

+- (Contrib) `vcenterreceiver`: Changing various default configurations for vcenterreceiver and removing warnings about future release. ([#32803](https://github.com/open-telemetry/opentelemetry-collector-contrib/issues/32803), [#32805](https://github.com/open-telemetry/opentelemetry-collector-contrib/issues/32805), [#32821](https://github.com/open-telemetry/opentelemetry-collector-contrib/issues/32821), [#32531](https://github.com/open-telemetry/opentelemetry-collector-contrib/issues/32531), [#32557](https://github.com/open-telemetry/opentelemetry-collector-contrib/issues/32557))
+  The resource attributes that will now be enabled by default are `vcenter.datacenter.name`, `vcenter.virtual_app.name`,
+  `vcenter.virtual_app.inventory_path`, `vcenter.vm_template.name`, and `vcenter.vm_template.id`. The metric
+  `vcenter.cluster.memory.used` will be removed.  The metrics `vcenter.cluster.vm_template.count` and

+- `deltatocumulativeprocessor`: Evict only stale streams ([#33014](https://github.com/open-telemetry/opentelemetry-collector-contrib/issues/33014))
+  Changes eviction behavior to only evict streams that are actually stale.
+  Currently, once the stream limit is hit, on each new stream the oldest tracked one is evicted.
+  Under heavy load this can rapidly delete all streams over and over, rendering the processor useless.
+
+- `vcenterreceiver`: Adds inititially disabled packet drop rate metric for VMs. ([#32929](https://github.com/open-telemetry/opentelemetry-collector-contrib/issues/32929))
+- `splunkhecreceiver`: Fix single metric value parsing ([#33084](https://github.com/open-telemetry/opentelemetry-collector-contrib/issues/33084))
+- `vcenterreceiver`: vcenterreceiver client no longer returns error if no Virtual Apps are found. ([#33073](https://github.com/open-telemetry/opentelemetry-collector-contrib/issues/33073))
+- `vcenterreceiver`: Adds inititially disabled new packet rate metrics to replace the existing ones for VMs & Hosts. ([#32835](https://github.com/open-telemetry/opentelemetry-collector-contrib/issues/32835))
+- `resourcedetectionprocessor`: Change type of `host.cpu.stepping` from int to string. ([#31136](https://github.com/open-telemetry/opentelemetry-collector-contrib/issues/31136))
+  - Disable the `processor.resourcedetection.hostCPUSteppingAsString` feature gate to get the old behavior.
+
+- `pkg/ottl`: Fixes a bug where function name could be used in a condition, resulting in a cryptic error message. ([#33051](https://github.com/open-telemetry/opentelemetry-collector-contrib/pull/33051))
