-2.1.0
+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
+    - Added: wait strategies for flat combining technique. Based on
+      research of Marsel Galimullin and Nikolai Rapotkin.
+    - 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
+    - Changed: cds::opt::buffer option is divided to initialized
+      (cds::opt::v::initialized_dynamic_buffer, cds::opt::v::initialized_static_buffer)
+      and uninitialized (cds::opt::v::uninitialized_dynamic_buffer, cds::opt::v::uninitialized_static_buffer)
+      ones. The old cds::opt::v::dynamic_buffer and cds::opt::v::static_buffer classes
+      are removed.
+    - Fixed: use-after-free bug in VyukovMPMCCycleQueue internal buffer.
+      To prevent this bug the queue uses an uninitialized buffer now.
+    - Fixed: rare priority inversion bug in MSPriorityQueue
+    - Added: for minimizing runtime of stress test the detail level for some test is added.
+      Command line argument --detail-level=N specifies what test should be ran: each
+      test with level not great than N will be ran. Instead of command line arg
+      the enviromnent variable CDSTEST_DETAIL_LEVEL=N can be used.
+      By default, the detail level is 0 that means only small set of the some test will be ran.

+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.
