• "PTL/Version.hh" header
• Improved template meta-programming
• Simplified interface
• CMake minimum version is now 3.8
• Improvements to task-groups
  • more flexible join functors
• Tasks protects against calling functions requiring references (references to stack variables may be invalid when task is executed)
• Replaced some raw pointers with smart pointers
• Migrated TBB to use global_control instead of task_scheduler_init
• Dropped support for compilers not supporting C++11 thread_local
• Renamed some member functions which were inconsistent. Significant ones:
  • PTL::ThreadPool::GetThreadIDs() -> PTL::ThreadPool::get_thread_ids()
  • PTL::ThreadPool:: GetThisThreadID() -> PTL::ThreadPool:: get_this_thread_id()
• Removed direct access to thread pointers in ThreadPool

PTL release for TomoPy

• create a tag for tomopy that can be downloaded within releases instead of checking it out as submodule

Version 0.0.1

• This is essentially a reference tag before the 1.0.0 release
• Initial "release" for version used by tomopy, etc. before the 1.0.0 release which is used by Geant4
• v1.0.0 is significantly different internally and included several member function re-naming for consistency
