 Deprecation Notices
 -------------------
 
-* Significant ABI changes are planned for struct rte_eth_dev to support up to
-  1024 queues per port. This change will be in release 2.2.
-  There is no backward compatibility planned from release 2.2.
-  All binaries will need to be rebuilt from release 2.2.
-
-* ABI changes are planned for struct rte_intr_handle, struct rte_eth_conf
-  and struct eth_dev_ops to support interrupt mode feature from release 2.1.
-  Those changes may be enabled in the release 2.1 with CONFIG_RTE_NEXT_ABI.
+* The following fields have been deprecated in rte_eth_stats:
+  ibadcrc, ibadlen, imcasts, fdirmatch, fdirmiss,
+  tx_pause_xon, rx_pause_xon, tx_pause_xoff, rx_pause_xoff
 
-* The EAL function rte_eal_pci_close_one is deprecated because renamed to
-  rte_eal_pci_detach.
+* The scheduler hierarchy structure (rte_sched_port_hierarchy) will change to
+  allow for a larger number of subport entries.
+  The number of available traffic_classes and queues may also change.
+  The mbuf structure element for sched hierarchy will also change from a single
+  32 bit to a 64 bit structure.
 
-* The Macros RTE_HASH_BUCKET_ENTRIES_MAX and RTE_HASH_KEY_LENGTH_MAX are
-  deprecated and will be removed with version 2.2.
+* The scheduler statistics structure will change to allow keeping track of
+  RED actions.
 
-* Significant ABI changes are planned for struct rte_mbuf, struct rte_kni_mbuf,
-  and several ``PKT_RX_`` flags will be removed, to support unified packet type
-  from release 2.1. Those changes may be enabled in the upcoming release 2.1
-  with CONFIG_RTE_NEXT_ABI.
+* librte_table: New functions for table entry bulk add/delete will be added
+  to the table operations structure.
 
-* librte_malloc library has been integrated into librte_eal. The 2.1 release
-  creates a dummy/empty malloc library to fulfill binaries with dynamic linking
-  dependencies on librte_malloc.so. Such dummy library will not be created from
-  release 2.2 so binaries will need to be rebuilt.
+* librte_table hash: Key mask parameter will be added to the hash table
+  parameter structure for 8-byte key and 16-byte key extendible bucket and
+  LRU tables.
 
-* The following fields have been deprecated in rte_eth_stats:
-  imissed, ibadcrc, ibadlen, imcasts, fdirmatch, fdirmiss,
-  tx_pause_xon, rx_pause_xon, tx_pause_xoff, rx_pause_xoff
+* librte_pipeline: The prototype for the pipeline input port, output port
+  and table action handlers will be updated:
+  the pipeline parameter will be added, the packets mask parameter will be
+  either removed (for input port action handler) or made input-only.
