# 2.0.0-alpha (2017-07-13)
# 2.0.0-alpha (2017-09-12)
A major release with many compatibility-breaking changes.
This code is work in progress and subject to changes.
Notable new features:
- Support for persistently mapped allocations - see VMA_MEMORY_REQUIREMENT_PERSISTENT_MAP_BIT.
- Introduction of VmaAllocation handle that you must retrieve from allocation functions and pass to deallocation functions, possibly next to normal VkBuffer and VkImage.
- Introduction of VmaAllocationInfo structure that you can retrieve from VmaAllocation handle to access parameters of the allocation (like VkDeviceMemory and offset) instead of retrieving them directly from allocation functions.
- Support for defragmentation (compaction) of allocations - see function vmaDefragment and related structures.
Compatibility-breaking changes:
- Modified struct VmaMemoryRequirements: removed member neverAllocate, added members: flags, pUserData. Added typedef VmaMemoryRequirementFlags, enum VmaMemoryRequirementFlagBits.
- Added VmaAllocation handle and VmaAllocationInfo structure. They are now used in modified signatures of functions: vmaAllocateMemory, vmaAllocateMemoryForBuffer, vmaAllocateMemoryForImage, vmaFreeMemory, vmaMapMemory, vmaUnmapMemory, vmaCreateBuffer, vmaDestroyBuffer, vmaCreateImage, vmaDestroyImage.
Additions:
- Added new functions related to introduction of VmaAllocation: vmaGetAllocationInfo, vmaSetAllocationUserData.
- Added support for temporarily unmapping persistently mapped memory for performance reasons: vmaUnmapPersistentlyMappedMemory, vmaMapPersistentlyMappedMemory.
- Added support for defragmentation: function vmaDefragment, structures: VmaDefragmentationInfo, VmaDefragmentationStats.
- Added struct member VmaAllocatorCreateInfo::pDeviceMemoryCallbacks, struct VmaDeviceMemoryCallbacks, function pointers: PFN_vmaAllocateDeviceMemoryFunction, PFN_vmaFreeDeviceMemoryFunction. They can be used to notify the user about calls to vkAllocateMemory and vkFreeMemory made by the library.
- Added struct member VmaAllocatorCreateInfo::flags, typedef VmaAllocatorFlags, enum VmaAllocatorFlagBits, enum value VMA_ALLOCATOR_EXTERNALLY_SYNCHRONIZED_BIT. It can be used to disable internal synchronization of an allocator for better performance if user wants to use it from single thread only or synchronize it externally.
- Introduction of `VmaAllocation` handle that you must retrieve from allocation functions and pass to deallocation functions next to normal `VkBuffer` and `VkImage`.
- Introduction of `VmaAllocationInfo` structure that you can retrieve from `VmaAllocation` handle to access parameters of the allocation (like `VkDeviceMemory` and offset) instead of retrieving them directly from allocation functions.
- Support for persistently mapped allocations - see `VMA_MEMORY_REQUIREMENT_PERSISTENT_MAP_BIT`.
- Support for custom memory pools - `VmaPool` handle, `VmaPoolCreateInfo` structure, `vmaCreatePool` function.
- Support for defragmentation (compaction) of allocations - see function `vmaDefragment` and related structures.
- Support for "lost allocations" - see appropriate chapter on documentation Main Page.
