v3.0.0

Added support for multiple GPU devices, detected and registered as "DEVICE_N" where N is the device number.
Added support for capturing function backtraces with allocations.
Added AlignedAllocator to provide aligned allocations for host memory.
Fixed builds using -stdlib=c++
Switched to camp::Platform: Platform::cpu is now Platform::host

v2.1.0

ENABLE_DEVICE_CONST CMake option to control whether device constant memory is enabled. It is now disabled by default.
DeviceAllocator that provides a pool for allocations inside GPU kernels.
Added "unset" operations for removing CUDA memory advice.
Extended C/Fortran API with more allocation strategies.
NamedAllocator that allows creating a new allocator that passes allocations through to underlying strategy
UMPIRE_VERSION_X are now defined as macros, rather than constexpr variables
Fixed reallocate to properly handle case where size == 0
AllocationStrategy constructor parameters re-ordered for consistency

Added symbol umpire_ver_1_detected to help detect version mismatches when linking multiple libraries that all use Umpire.
Re-introduced pool algorithm used in pre-1.0.0 releases as DynamicPoolList, and renamed current strategy to DynamicPoolMap. DynamicPool is now an alias to DynamicPoolMap.
Fix signature of C function umpire_resourcemanager_make_allocator_pool to take size_t not int.
Restored getActualSize for all Allocator types

Fixed a bug in DynamicPool where memory could be leaked when allocating a new block using the "minimum size" for an allocation smaller than the block.

Umpire is MPI-aware (outputs rank information to logs and replays) when configured with the option ENABLE_MPI=On, and umpire::initialize(MPI_Comm comm) must be called.
AllocationStrategies may be wrapped with multiple extra layers. To "unwrap" an Allocator to a specific strategy, the umpire::util::unwrap_allocator method can be used, for example:

auto dynamic_pool = umpire::util::unwrap_allocatorumpire::strategy::DynamicPool(allocator);

This will impact users who have been using DynamicPool::coalesce. The cookbook recipe has been updated accordingly, and the previous code snippet can be used.
Umpire now directs log and replay output to files, one per process. The filenames can be controlled by the environment variable UMPIRE_OUTPUT_BASENAME
ENABLE_CUDA now set to Off by default.
Allocations for 0 bytes now always return a valid pointer that cannot be read or written. These pointers can be deallocated.
