+### Bugfixes
+
+- Fix an issue where Prometheus metric name validation scheme was set by default to UTF-8. It is now set back to the
+  previous "legacy" scheme. An experimental flag `--feature.prometheus.metric-validation-scheme` can be used to switch 
+  it to `utf-8` to experiment with UTF-8 support.

 ### Breaking changes
 
 - (_Experimental_) In `prometheus.write.queue` changed `parallelism` from attribute to a block to allow for dynamic scaling. (@mattdurham)
 
+- Remove `tls_basic_auth_config_path` attribute from `prometheus.exporter.mongodb` configuration as it does not configure TLS client
+  behavior as previously documented.
+
+- Remove `encoding` and `encoding_file_ext` from `otelcol.exporter.awss3` component as it was not wired in to the otel component and 
+  Alloy does not currently integrate the upstream encoding extensions that this would utilize.
+
 ### Features
 
+- Add a `otelcol.receiver.tcplog` component to receive OpenTelemetry logs over a TCP connection. (@nosammai)

 - (_Public preview_) Add `otelcol.receiver.filelog` component to read otel log entries from files (@dehaansa)
