+- The background (elastic) store graphs for exhausted duration, and the wait duration histogram, have been separated from the foreground (regular) graphs. [#156868][#156868]

+
+- A mechanism that prevents unsafe replication changes from causing loss of quorum now functions correctly. An internal function has been fixed to properly return errors, enhancing the reliability of replication safeguards. [#156521][#156521]
+- Fixed a bug that could cause internal errors for queries using generic query plans with `NULL` placeholder values. [#156977][#156977]
+
+<h3 id="v25-2-10-performance-improvements">Performance improvements</h3>
+
+- The cost of generic query plans is now calculated based on worst-case selectivities for placeholder equalities (e.g., `x = $1`). This reduces the chance of suboptimal generic query plans being chosen when `plan_cache_mode=auto`. [#156797][#156797]

+<h3 id="v25-2-10-miscellaneous">Miscellaneous</h3>
+
+- Span config reconciliation jobs no longer fail on the
+  destination after failover from a PCR stream of a system virtual cluster. [#156810][#156810]
