-2.2.12
+3.0.16
+=====
+
+Upgrading
+---------
- - Nothing specific to this release, but please see previous upgrading sections,
- especially if you are upgrading from 2.2.
++ - Cassandra is now relying on the JVM options to properly shutdown on OutOfMemoryError. By default it will
++ rely on the OnOutOfMemoryError option as the ExitOnOutOfMemoryError and CrashOnOutOfMemoryError options
++ are not supported by the older 1.7 and 1.8 JVMs. A warning will be logged at startup if none of those JVM
++ options are used. See CASSANDRA-13006 for more details.
++ - Cassandra is not logging anymore by default an Heap histogram on OutOfMemoryError. To enable that behavior
++ set the 'cassandra.printHeapHistogramOnOutOfMemoryError' System property to 'true'. See CASSANDRA-13006
++ for more details.
+
+Materialized Views
+-------------------
+ - Following a discussion regarding concerns about the design and safety of Materialized Views, the C* development
+ community no longer recommends them for production use, and considers them experimental. Warnings messages will
+ now be logged when they are created. (See https://www.mail-archive.com/dev@cassandra.apache.org/msg11511.html)
+ - An 'enable_materialized_views' flag has been added to cassandra.yaml to allow operators to prevent creation of
+ views
+
+3.0.15
+=====
+
+Upgrading
+---------
+ - Nothing specific to this release, but please see previous upgrading sections,
+ especially if you are upgrading from 2.2.
+
+Compact Storage
+---------------
+ - Starting version 4.0, Thrift and COMPACT STORAGE is no longer supported.
+ 'ALTER ... DROP COMPACT STORAGE' statement makes Compact Tables CQL-compatible,
+ exposing internal structure of Thrift/Compact Tables. You can find more details
+ on exposed internal structure under:
+ http://cassandra.apache.org/doc/latest/cql/appendices.html#appendix-c-dropping-compact-storage
+
+ For uninterrupted cluster upgrades, drivers now support 'NO_COMPACT' startup option.
+ Supplying this flag will have same effect as 'DROP COMPACT STORAGE', but only for the
+ current connection.
+
+ In order to upgrade, clients supporting a non-compact schema view can be rolled out
+ gradually. When all the clients are updated 'ALTER ... DROP COMPACT STORAGE' can be
+ executed. After dropping compact storage, ’NO_COMPACT' option will have no effect
+ after that.
+
+Materialized Views
+-------------------
+ - Cassandra will no longer allow dropping columns on tables with Materialized Views.
+ - A change was made in the way the Materialized View timestamp is computed, which
+ may cause an old deletion to a base column which is view primary key (PK) column
+ to not be reflected in the view when repairing the base table post-upgrade. This
+ condition is only possible when a column deletion to an MV primary key (PK) column
+ not present in the base table PK (via UPDATE base SET view_pk_col = null or DELETE
+ view_pk_col FROM base) is missed before the upgrade and received by repair after the upgrade.
+ If such column deletions are done on a view PK column which is not a base PK, it's advisable
+ to run repair on the base table of all nodes prior to the upgrade. Alternatively it's possible
+ to fix potential inconsistencies by running repair on the views after upgrade or drop and
+ re-create the views. See CASSANDRA-11500 for more details.
+ - Removal of columns not selected in the Materialized View (via UPDATE base SET unselected_column
+ = null or DELETE unselected_column FROM base) may not be properly reflected in the view in some
+ situations so we advise against doing deletions on base columns not selected in views
+ until this is fixed on CASSANDRA-13826.
