+# 2.1.0-beta.1 (2018-08-24)
+
+Major release after many months of development in "development" branch and features branches. Many new features added, some bugs fixed. API stays backward-compatible.
+
+Major changes:
+
+- Added linear allocation algorithm, accessible for custom pools, that can be used as free-at-once, stack, double stack, or ring buffer. See "Linear allocation algorithm" documentation chapter.
+  - Added `VMA_POOL_CREATE_LINEAR_ALGORITHM_BIT`, `VMA_ALLOCATION_CREATE_UPPER_ADDRESS_BIT`.
+- Added feature to record sequence of calls to the library to a file and replay it using dedicated application. See documentation chapter "Record and replay".
+  - Recording: added `VmaAllocatorCreateInfo::pRecordSettings`.
+  - Replaying: added VmaReplay project.
+  - Recording file format: added document "docs/Recording file format.md".
+- Improved support for non-coherent memory.
+  - Added functions: `vmaFlushAllocation`, `vmaInvalidateAllocation`.
+  - `nonCoherentAtomSize` is now respected automatically.
+  - Added `VmaVulkanFunctions::vkFlushMappedMemoryRanges`, `vkInvalidateMappedMemoryRanges`.
+- Improved debug features related to detecting incorrect mapped memory usage. See documentation chapter "Debugging incorrect memory usage".
+  - Added debug macro `VMA_DEBUG_DETECT_CORRUPTION`, functions `vmaCheckCorruption`, `vmaCheckPoolCorruption`.
+  - Added debug macro `VMA_DEBUG_INITIALIZE_ALLOCATIONS` to initialize contents of allocations with a bit pattern.
+  - Changed behavior of `VMA_DEBUG_MARGIN` macro - it now adds margin also before first and after last allocation in a block.
+- Changed format of JSON dump returned by `vmaBuildStatsString` (not backward compatible!).
+  - Custom pools and memory blocks now have IDs that don't change after sorting.
+  - Added properties: "CreationFrameIndex", "LastUseFrameIndex", "Usage".
+  - Changed behavior of `vmaGetAllocationInfo` and `vmaTouchAllocation` to update `allocation.lastUseFrameIndex` even if allocation cannot become lost.
+  - Changed VmaDumpVis tool to use these new properties for better coloring.
+
+Minor changes:
+
+- Improved logic of `vmaFindMemoryTypeIndex` for some cases, especially integrated GPUs.
+- VulkanSample application: Removed dependency on external library MathFu. Added own vector and matrix structures.
+- Code changes that improve compatibility with various platforms, including: Visual Studio 2012, 32-bit code, C compilers.
+  - Changed usage of "VK_KHR_dedicated_allocation" extension in the code to be optional, driven by macro `VMA_DEDICATED_ALLOCATION`, for compatibility with Android.
+- Many additions and fixes in documentation, including description of new features, as well as "Validation layer warnings".
+- Other bugfixes.
+
 # 2.0.0 (2018-03-19)
 
 A major release with many compatibility-breaking changes.

@@ -43,6 +43,7 @@ Additional features:
 - Support for memory mapping, reference-counted internally. Support for persistently mapped memory: Just allocate with appropriate flag and you get access to mapped pointer.
 - Support for non-coherent memory. Functions that flush/invalidate memory. nonCoherentAtomSize is respected automatically.
 - Custom memory pools: Create a pool with desired parameters (e.g. fixed or limited maximum size) and allocate memory out of it.
+- Linear allocator: Create a pool with linear algorithm and use it for much faster allocations and deallocations in free-at-once, stack, double stack, or ring buffer fashion.
 - Support for VK_KHR_dedicated_allocation extension: Just enable it and it will be used automatically by the library.
 - Defragmentation: Call one function and let the library move data around to free some memory blocks and make your allocations better compacted.
 - Lost allocations: Allocate memory with appropriate flags and let the library remove allocations that are not used for many frames to make room for new ones.
