 ### Minor Improvements
 
-* {% ghi 3077 %}, {% ghi 3079 %}, {% ghi 3083 %} Avoid filling OS page cache by setting the
-  `FSDataOutputStream.setDropBehind` flag when performing likely one-time file
-  accesses, as with WAL input and output files and major compaction input files. This should allow
-  files that might benefit more from caching to stay in the cache longer. {% ghi 3083 %}
-  introduces a new property, table.compaction.major.output.drop.cache, for dropping pages
-  from the OS page cache for major compaction output files. These changes will only have an
-  impact on HDFS FileSystem implementations and operating systems that support them.
