0.2.5 (Stable)

• Made threadpool compatible to boost::thread 1.37
• Fixed hang problem in shutdown method (Thanks to Sohail Somani)
• Adapted repository layout to boost (Thanks to Alex Ott)

0.2.4 (Stable)

• Made threadpool compatible to boost::thread 1.35.x code base
• Fixed compiler warning in scope_guard.hpp

0.2.4 (Stable)

• Made threadpool compatible to boost::thread 1.35.x code base
• Fixed compiler warning in scope_guard.hpp

0.2.3 (Development)

• Implemented workaround for Sun C++ Pro compiler bug in pool_core
• Removed subtask implementation (there was no demand for this feature)
• Improved shutdown policies

0.2.2 (Development)

• Refactored SizePolicy and added SizePolicyController
• Moved policies into separate files
• Fixed some compiler problems (GCC)
• Implemented size_controller handling
• Implemented two size policies: static_size and fixed_size
• Refactored worker_thread handling, moved policies from pool_core to pool
• Specialized schedule function for usage with futures
• Added compile test project
• Improved constness in pool core class
• Fixed timed wait
• Implemented futures (in progress)
• Added result_type to all functors

0.2.1 (Development)

• Pool base class (thread_pool) has now reference semantics.
• Large refactorings: Removed scoped_pool, reimplemented worker (now worker_thread)
• Fixed odd resize behaviour. Now resize changes the number of threads immediately.
• Apply pimpl idiom on pool core class (to make the ugly scoped_pool class needless)
• Introduced scheduling policies
• Switched to policy-based design (PBD), inspired by Scott Meyers C++ workshop
• Cosmetic code change: Replaced keyword 'class' with 'typename' in template definitions
• Revised tutorials
• New requirements: tasks functions should not and schedulers shall not throw exceptions

0.2.0 (Development)

• Moved threadpool into the boost namespace: boost::threadpool
• Used keyword volatile to indicate thread-safe member functions
• Used volatile on primitve types were appropriate
• Moved worker to detail directory
• Fixed thread deletion
• Extended wait functionality (waiting for idle threads was implemented)
• Renamed 'join()' to 'wait()' as 'join' indicates the termination of thread. That was not the case in pool::join.
• Changed internal container of lifo and fifo schedulers to improve efficiency.
• Improved code reference documentation (source code browser)
• Renamed thread_func into task_func
• Added += operator to scoped_pool to ease scheduling of tasks
• Refactored file structures and class names
• Added a new task concept (named subtask) which allows the combination of sequential and parallel execution
• Added new task adaptor for looped or timed tasks: looped_task_func
• Introduced function clear() which can be used to remove all tasks from the pool and schedulers
• New function pool::active() which returns the number of active tasks

0.1.8 (Development)

• Fixed some compile errors which were reported by gcc
• Wrote tutorial "Prioritized Tasks"

0.1.7 (Development)

• Added Visual Studio 2005 project files for tutorial and examples

0.1.6 (Development)

• Replaced task adaptor 'task' with boost::bind
• Workers are unregistered from thread_group when they are terminated
• Working on example boost::iostreams packet_filter

0.1.5 (Development)

• Finished threadpool reference
• Class pool_adaptor was replaced by smart_pool
• Minor pool improvements
• First tutorial page online

0.1.4 (Development)

• Created the pool's homepage: http://threadpool.sourceforge.net
• Improved documentation
• Added build scripts

0.1.3 (Development)

• First public release
• Added mergesort example
• Added tutorial
• Implementation of threadpool core and related classes
