-    TODO
+2.2.0
+    General release
+    - Changed: CMake is used for build libcds. Ancient build.sh is removed
+    - Changed: unit and stress tests are migrated to googletest framework
+    - Fixed: serious bug in MichaelSet::emplace() function
+      New node was created twice from the arguments by move semantics. 
+      However, move semantics may change internal state of the argument
+      that can lead to an incorrect element in the set and even
+      to an incorrect key that breaks the set logic.
+    - Fixed: bug in FeldmanHashSet::erase_at( iterator ): due an error
+      in precondition checking the function can incorrectly return false.
+    - Fixed: possible double-free case in flat combining algorithm. 
+      Thanks to Amila Jayasekara who points me to this problem
+
+2.1.0 06.01.2016
+    General release
+    - Added: FeldmanHashSet/Map - an interesting hash map algorithm
+      based on multi-level array, requires perfect hashing or fixed-sized keys.
+      Supports thread-safe bidirectional iterators.
+    - Added: BronsonAVLTreeMap - Bronson's et al AVL tree implementation
+    - Added: CMake build script, thanks to Eugeny Kalishenko
+    - Changed: SplitList performance improving, thanks to Mike Krinkin
+    - Changed: semantic of member functions extract(), get() and its
+      variants for MichaelList RCU-based specialization: extract() does not
+      require RCU locking, get() now returns special wrapper object of type raw_ptr,
+      see doc.
+      Thus, semantics of extract()/get() of all RCU-based set and maps based on 
+      MichaelList (MichaelSet/Map, SplitListSet/Map) has been changed too.
+    - Changed: SplitListSet/Map functions get() and get_with() return special wrapper
+      object of type raw_ptr, see doc.
+    - Removed: SplitListSet/Map force_dispose() function.
+    - cds::lock namespace is renamed to cds::sync. All classes defined in cds::lock namespace 
+      are moved to cds::sync with new names (for example, cds::lock::SpinLock is renamed to
+      cds::sync::spin_lock). cds::lock namespace and its contents is deprecated, it is kept 
+      for backward compatibility.
+    - The library has been checked by ThreadSanitizer, a lot of bugs has been fixed
+    - Added support for clang 3.7 with libc++
