+  When a Collector process exits unexpectedly, the Supervisor now can add the relevant
+  tail of the Collector logs to the health and remote config failure messages sent
+  to the OpAMP server. This helps operators understand why a remote config failed
+  without first logging into the host to inspect `agent.log`. This behavior is
+  disabled by default; set `agent::collector_crash_log_snippet_kib` to a positive
+  KiB count, such as `4`, up to `1024` (1 MiB) to enable it.

-  Samples are collected via `$currentOp`, with idle connections and administrative commands
-  filtered out. Each event includes obfuscated query text and operation metadata.
-  The `logs` signal is at `development` stability; attribute names may change until OTel
-  `db.server.query_sample` conventions stabilize. The `metrics` signal remains at `beta`.
+  When the gate is enabled, traces, metrics, logs, and profiles all convert
+  pdata into Kafka records at request-creation time and use a custom
+  Request for queue/batch sizing. `queue_batch.sizer: items` then counts
+  Kafka records, not OTLP items. The persistent queue (`sending_queue.storage`)
+  is not supported with this gate; configuring both produces an error at
+  startup. Default OFF.

-  (llm.{input,output}_messages.N.message.*).
+  In the iter loop, pending configuration updates (SetMaximumTraceSizeBytes and
+  SetSamplingPolicy) are now drained before processing incoming trace batches.
+  This prevents a non-deterministic Go select from picking the workChan case
+  before a config update channel, which previously caused TestDropLargeTraces
+  to fail flakily on CI.

+  Fixes a memory leak in consumers of internal/sqlquery (sqlserver, postgresql, mysql, oracledb, sqlquery receivers). Previously, when ColumnTypes or row scanning returned early with an error, or when the context was cancelled mid-iteration, sql.Rows was never closed, so the underlying connection stayed marked in-use in the *sql.DB pool. On drivers that allocate per-connection buffers (e.g. go-mssqldb's 64 KiB TDS buffer), this manifested as steady RSS growth under long-running scrapes.
