@@@ -13,56 -13,6 +13,57 @@@ restore snapshots created with the prev
  'sstableloader' tool. You can upgrade the file format of your snapshots
  using the provided 'sstableupgrade' tool.
  
 +3.0
 +===
 +
 +New features
 +------------
 +   - Materialized Views, which allow for server-side denormalization, is now
 +     available. Materialized views provide an alternative to secondary indexes
 +     for non-primary key queries, and perform much better for indexing high
 +     cardinality columns.
 +     See http://www.datastax.com/dev/blog/new-in-cassandra-3-0-materialized-views
 +
 +
 +Upgrading
 +---------
 +   - 3.0 requires Java 8u20 or later.
 +   - The default JVM GC has been changed to G1GC.
 +   - The default JVM flag -XX:+PerfDisableSharedMem will cause the following tools JVM
 +     to stop working: jps, jstack, jinfo, jmc, jcmd as well as 3rd party tools like Jolokia.
 +     If you wish to use these tools you can comment this flag out in cassandra-env.{sh,ps1}
 +   - New write stages have been added for batchlog and materialized view mutations
 +     you can set their size in cassandra.yaml
 +   - User defined functions are now executed in a sandbox.
 +     To use UDFs and UDAs, you have to enable them in cassandra.yaml.
 +   - New SSTable version 'la' with improved bloom-filter false-positive handling
 +     compared to previous version 'ka' used in 2.2 and 2.1. Running sstableupgrade
 +     is not necessary but recommended.
 +   - Before upgrading to 3.0, make sure that your cluster is in complete agreement
 +     (schema versions outputted by `nodetool describecluster` are all the same).
 +   - Schema metadata is now stored in the new `system_schema` keyspace, and
 +     legacy `system.schema_*` tables are now gone; see CASSANDRA-6717 for details.
 +   - Pig's CassandraStorage has been removed. Use CqlNativeStorage instead.
 +   - Hadoop BulkOutputFormat and BulkRecordWriter have been removed; use
 +     CqlBulkOutputFormat and CqlBulkRecordWriter instead.
 +   - Hadoop ColumnFamilyInputFormat and ColumnFamilyOutputFormat have been removed;
 +     use CqlInputFormat and CqlOutputFormat instead.
 +   - Hadoop ColumnFamilyRecordReader and ColumnFamilyRecordWriter have been removed;
 +     use CqlRecordReader and CqlRecordWriter instead.
 +   - hinted_handoff_enabled in cassandra.yaml no longer supports a list of data centers.
 +     To specify a list of excluded data centers when hinted_handoff_enabled is set to true,
 +     use hinted_handoff_disabled_datacenters, see CASSANDRA-9035 for details.
 +   - The `sstable_compression` and `chunk_length_kb` compression options have been deprecated.
 +     The new options are `class` and `chunk_length_in_kb`. Disabling compression should now
 +     be done by setting the new option `enabled` to `false`.
 +   - Only map syntax is now allowed for caching options. ALL/NONE/KEYS_ONLY/ROWS_ONLY syntax
 +     has been deprecated since 2.1.0 and is being removed in 3.0.0.
 +   - Batchlog entries are now stored in a new table - system.batches.
 +     The old one has been deprecated.
 +   - JMX methods set/getCompactionStrategyClass have been removed, use
 +     set/getCompactionParameters or set/getCompactionParametersJson instead.
++   - SizeTieredCompactionStrategy parameter cold_reads_to_omit has been removed.
