-# 2.0.0-alpha (2017-09-12)
+# 2.0.0 (2018-03-19)
 
 A major release with many compatibility-breaking changes.
 
-This code is work in progress and subject to changes.
-
 Notable new features:
 
 - 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 reference-counted mapping and persistently mapped allocations - see `vmaMapMemory`, `VMA_ALLOCATION_CREATE_MAPPED_BIT`.
+- Support for custom memory pools - see `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.

 - Statistics: Obtain detailed statistics about the amount of memory used, unused, number of allocated blocks, number of allocations etc. - globally, per memory heap, and per memory type.
 - Debug annotations: Associate string with name or opaque pointer to your own data with every allocation.
 - JSON dump: Obtain a string in JSON format with detailed map of internal state, including list of allocations and gaps between them.

+# VMA Dump Vis
+
+Vulkan Memory Allocator Dump Visualization. It is an auxiliary tool that can visualize internal state of [Vulkan Memory Allocator](../../README.md) library on a picture. It is a Python script that must be launched from command line with appropriate parameters.
+
+## Requirements
+
+- Python 3 installed
+- [Pillow](http://python-pillow.org/) - Python Imaging Library (Fork) installed
+
+## Usage
+
+```
+python VmaDumpVis.py -o OUTPUT_FILE INPUT_FILE
+```
+
+* `INPUT_FILE` - path to source file to be read, containing dump of internal state of the VMA library in JSON format (encoding: UTF-8), generated using `vmaBuildStatsString()` function.
+* `OUTPUT_FILE` - path to destination file to be written that will contain generated image. Image format is automatically recognized based on file extension. List of supported formats can be found [here](http://pillow.readthedocs.io/en/latest/handbook/image-file-formats.html) and includes: BMP, GIF, JPEG, PNG, TGA.
+
+You can also use typical options:
+
+* `-h` - to see help on command line syntax
+* `-v` - to see program version number
+
+## Example output
+
+![Example output](README_files/ExampleOutput.png "Example output")
+
+## Legend
+
+* ![Free space](README_files/Legend_Bkg.png "Free space") Light gray without border - a space in Vulkan device memory block unused by any allocation.
+* ![Buffer](README_files/Legend_Buffer.png "Buffer") Yellow rectangle - buffer.
+* ![Image Optimal](README_files/Legend_ImageOptimal.png "Image Optimal") Aqua rectangle - image with TILING_OPTIMAL.
+* ![Image Linear](README_files/Legend_ImageLinear.png "Image Linear") Green rectangle - image with TILING_LINEAR.
+* ![Details](README_files/Legend_Details.png "Details") Black bar or rectangle - one or more allocations of any kind too small to be visualized as filled rectangles.
