0.16
    1) Changed API for coderef's subroutines in 'depends' of rules. Now first
       parameter is reference to CHI::Cascade::Rule object and other are
       'qr_params'
    2) CHI::Cascade::Rule object now has a method 'cascade' which returns a
       CHI::Cascade instance for this rule. You can use it in 'depends'
       subroutines

0.15
    1) Corrections if cascade rules have a 'depends' option as coderef. Backward
       compatible. Now coderef can return arrayref of dependencies. Before it
       could return only one dependence as plain text. No tests yet for this
    2) Tests are rewritten and optimised
    3) Added a FastMmap driver's tests
    4) Added tests when dependencies are coderef (t/lib/test_02.pm)

0.14 (stable)
    1) Improved tests in accordance with reports version 0.13
    2) Fixed few misprints in Changes & TODO files

0.13 (stable)
    1) Fix bug - sometimes generated warnging for trigger time (was undefined)
    2) Now a compute code can throw die with CHI::Cascade::Value object - this value
       will be returned from run method but value will not be saved in cache as
       computed value
    3) Improved a behavior with some buggy situations with cache (cache doesn't
       save a value by some reasons for example)

0.12
    - More stable version as i think ;-) Please use it
    - Improved signal handling in tests (for memcached killing)
    - Fixed bug - dependencies as sub {} didn't get a qr_params properly
    - Fixed rule's bug

0.11
    - Fixed bug (sometime dead locks were after target locking)
    - Added 'busy_lock' option in contructor and to 'rule' method
    - All 'set's in cache executed with expire as 'never' (excluding locking of
      targets)

0.1
    - Changed API of execution 'code' of rules
    - Now you can use instances of CHI::Cascade::Rule in your target codes
    - Now you can pass any parameters to target codes described in rules

0.05
    - More improved the test t/03_memcached_multi.t
    - Tests with memcached for root user are not started (passed)
      Now they are started
    - More ready distributive

0.03
    - Fixed bugs in tests (for example not be stopped memcached)
    - New test - multi-process reading/getting from memcached (with forks)
    - Added documentation about constructor and methods.

0.02
    - Added repo meta info of github.com repository
    - few changes of Makefile.PL ('README' file is generated by auto)
    - Added 'Changes' file ;-)
    - Added TODO file

0.01
    - First release
