+|https://jira.issues.couchbase.com/browse/MB-65348/[MB-65348]
+
+a|The update introduces a Content-Type header to the Prometheus scrape endpoint (/metrics).
+This change aims to enhance the integration by specifying the data format explicitly.
+The implementation should be straightforward, however, the engineer will evaluate its complexity and impact on backward compatibility to decide on backporting.
+This improvement will ensure better interoperability and adherence to standards.
+Further assessment will be conducted to determine the size and feasibility of this change.

+
+|https://jira.issues.couchbase.com/browse/MB-68969/[MB-68969]
+
+a|Recent updates have enhanced the sargability of multi-collection indexes in N1QL + FTS, particularly when `include_in_all` is set from multiple child fields.
+This involves building FTS index objects with only applicable type mappings, improving efficiency.
+Changes have been incorporated in various builds, ensuring that the FTS index's _all composite field exhibits enhanced sargability.
+These updates aim to streamline query processing and ensure more precise index application in diverse data models.
+The improvements are part of ongoing efforts to optimize database functionality and performance.

+
+a|Problem:
+
+A query may return incorrect result under the following conditions:
+
+* query contains one or more joins
+* one of the joins involves a subquery (FROM clause subquery)
+* the FROM clause subquery has a GROUP BY and/or aggregates
+* the FROM clause subquery can take advantage of index group/aggregate pushdown
+(this requires an appropriate secondary index)
+* CBO is ON, and UPDATE STATISTICS has been run on all keyspaces/indexes involved
+
+Resolution:
+
+The issue has been fixed in version 7.6.10.
