+
+### 2.0.6
+
+ - Improve MZ_ZIP_FLAG_WRITE_ZIP64 documentation

+- Miniz automatically switches to the ZIP64 format when the created ZIP files goes over ZIP file limits
 - Similar to [SQLite](https://www.sqlite.org/amalgamation.html) the Miniz source code is amalgamated into one miniz.c/miniz.h pair in a build step (amalgamate.sh). Please use miniz.c/miniz.h in your projects

 ### v1.16 BETA Oct 19, 2013
 
@@ -36,7 +145,7 @@ The inflator now has a new failure status TINFL_STATUS_FAILED_CANNOT_MAKE_PROGRE
 - The inflator coroutine func. is subtle and complex so I'm being cautious about this release. I would greatly appreciate any help with testing or any feedback.
          I feel good about these changes, and they've been through several hours of automated testing, but they will probably not fix anything for the majority of prev. users so I'm
          going to mark this release as beta for a few weeks and continue testing it at work/home on various things.
-- The inflator in raw (non-zlib) mode is now usable on gzip or similiar data streams that have a bunch of bytes following the raw deflate data (problem discovered by rustyzip author williamw520).
+- The inflator in raw (non-zlib) mode is now usable on gzip or similar data streams that have a bunch of bytes following the raw deflate data (problem discovered by rustyzip author williamw520).
          This version should *never* read beyond the last byte of the raw deflate data independent of how many bytes you pass into the input buffer. This issue was caused by the various Huffman bitbuffer lookahead optimizations, and
          would not be an issue if the caller knew and enforced the precise size of the raw compressed data *or* if the compressed data was in zlib format (i.e. always followed by the byte aligned zlib adler32).
          So in other words, you can now call the inflator on deflate streams that are followed by arbitrary amounts of data and it's guaranteed that decompression will stop exactly on the last byte.
@@ -57,7 +166,7 @@ Merged over a few very minor bug fixes that I fixed in the zip64 branch. This is
 Interim bugfix release while I work on the next major release with zip64 and streaming compression/decompression support. Fixed the MZ_ZIP_FLAG_DO_NOT_SORT_CENTRAL_DIRECTORY bug (thanks kahmyong.moon@hp.com), which could cause the locate files func to not find files when this flag was specified. Also fixed a bug in mz_zip_reader_extract_to_mem_no_alloc() with user provided read buffers (thanks kymoon). I also merged lots of compiler fixes from various github repo branches and Google Code issue reports. I finally added cmake support (only tested under for Linux so far), compiled and tested with clang v3.3 and gcc 4.6 (under Linux), added defl_write_image_to_png_file_in_memory_ex() (supports Y flipping for OpenGL use, real-time compression), added a new PNG example (example6.c - Mandelbrot), and I added 64-bit file I/O support (stat64(), etc.) for glibc.
 
 - Critical fix for the MZ_ZIP_FLAG_DO_NOT_SORT_CENTRAL_DIRECTORY bug (thanks kahmyong.moon@hp.com) which could cause locate files to not find files. This bug
-        would only have occured in earlier versions if you explicitly used this flag, OR if you used mz_zip_extract_archive_file_to_heap() or mz_zip_add_mem_to_archive_file_in_place()
+        would only have occurred in earlier versions if you explicitly used this flag, OR if you used mz_zip_extract_archive_file_to_heap() or mz_zip_add_mem_to_archive_file_in_place()
         (which used this flag). If you can't switch to v1.15 but want to fix this bug, just remove the uses of this flag from both helper funcs (and of course don't use the flag).
 - Bugfix in mz_zip_reader_extract_to_mem_no_alloc() from kymoon when pUser_read_buf is not NULL and compressed size is > uncompressed size
 - Fixing mz_zip_reader_extract_*() funcs so they don't try to extract compressed data from directory entries, to account for weird zipfiles which contain zero-size compressed data on dir entries.

 ## Usage
 
-Please use the files from the [releases page](https://github.com/richgel999/miniz/releases) in your projects. Do not use the git checkout directly! The different source and header files are [amalgamated](https://www.sqlite.org/amalgamation.html) into one `miniz.c`/`miniz.h` pair in a build step (`amalgamate.sh`). Include `miniz.c` and `miniz.h` in your project to use Miniz.
+Releases are available at the [releases page](https://github.com/richgel999/miniz/releases) as a pair of `miniz.c`/`miniz.h` files which can be simply added to a project. To create this file pair the different source and header files are [amalgamated](https://www.sqlite.org/amalgamation.html) during build. Alternatively use as cmake or meson module (or build system of your choice).

 * A drop-in replacement for zlib's most used API's (tested in several open source projects that use zlib, such as libpng and libzip).
 * Fills a single threaded performance vs. compression ratio gap between several popular real-time compressors and zlib. For example, at level 1, miniz.c compresses around 5-9% better than minilzo, but is approx. 35% slower. At levels 2-9, miniz.c is designed to compare favorably against zlib's ratio and speed. See the miniz performance comparison page for example timings.
 * Not a block based compressor: miniz.c fully supports stream based processing using a coroutine-style implementation. The zlib-style API functions can be called a single byte at a time if that's all you've got.
-* Easy to use. The low-level compressor (tinfl) and decompressor (tdefl) have simple state structs which can be saved/restored as needed with simple memcpy's. The low-level codec API's don't use the heap in any way.

 * Entire inflater (including optional zlib header parsing and Adler-32 checking) is implemented in a single function as a coroutine, which is separately available in a small (~550 line) source file: miniz_tinfl.c
 * A fairly complete (but totally optional) set of .ZIP archive manipulation and extraction API's. The archive functionality is intended to solve common problems encountered in embedded, mobile, or game development situations. (The archive API's are purposely just powerful enough to write an entire archiver given a bit of additional higher-level logic.)
 
+## Building miniz - Using vcpkg
+
+You can download and install miniz using the [vcpkg](https://github.com/Microsoft/vcpkg) dependency manager:
+
+    git clone https://github.com/Microsoft/vcpkg.git
+    cd vcpkg
+    ./bootstrap-vcpkg.sh
+    ./vcpkg integrate install
+    ./vcpkg install miniz
+
+The miniz port in vcpkg is kept up to date by Microsoft team members and community contributors. If the version is out of date, please [create an issue or pull request](https://github.com/Microsoft/vcpkg) on the vcpkg repository.

 ## Known Problems
 
-* No support for encrypted archives. Not sure how useful this stuff is in practice. Zip encryption is very weak.
+* No support for encrypted archives. Not sure how useful this stuff is in practice.
 * Minimal documentation. The assumption is that the user is already familiar with the basic zlib API. I need to write an API wiki - for now I've tried to place key comments before each enum/API, and I've included 6 examples that demonstrate how to use the module's major features.

 ## Patents
 
-I was recently asked if miniz avoids patent issues. miniz purposely uses the same core algorithms as the ones used by zlib. The compressor uses vanilla hash chaining as described [here](http://www.gzip.org/zlib/rfc-deflate.html#algorithm). Also see the [gzip FAQ](http://www.gzip.org/#faq11). In my opinion, if miniz falls prey to a patent attack then zlib/gzip are likely to be at serious risk too.
