The most important changes from Xamarin.Android's point of view:

  * Many micro-optimizations collectively reduce CPU cycles by ~2.3%.
  * Fix an incorrect result from a query that uses a view that
    contains a compound SELECT in which only one arm contains a RIGHT
    JOIN and where the view is not the first FROM clause term of the
    query that contains the view.
  * Fix the initial-prefix optimization for the REGEXP extension so
    that it works correctly even if the prefix contains characters
    that require a 3-byte UTF8 encoding.
  * Fix a performance regression in the query planner associated with
    rearranging the order of FROM clause terms in the presences of a
    LEFT JOIN.
  * Apply fixes for CVE-2022-35737
