+v2.18 Intel Intelligent Storage Acceleration Library Release Notes
+==================================================================
+
+RELEASE NOTE CONTENTS
+1. KNOWN ISSUES
+2. FIXED ISSUES
+3. CHANGE LOG & FEATURES ADDED
+
+1. KNOWN ISSUES
+----------------
+
+* Perf tests do not run in Windows environment.
+
+* 32-bit lib is not supported in Windows.
+
+2. FIXED ISSUES
+---------------
+
+v2.18
+
+* Mac OS X/darwin systems no longer require the --target=darwin config option.
+  The autoconf canonical build should detect.
+
+v2.17
+
+* Fix igzip using 32K window and a shared object
+
+* Fix igzip undefined instruction error on Nehalem.
+
+* Fixed issue in crc performance tests where OS optimizations turned cold cache
+  tests into warm tests.
+
+v2.15
+
+* Fix for windows register save in gf_6vect_mad_avx2.asm.  Only affects windows
+  versions of ec_encode_data_update() running with AVX2.  A GP register was not
+  properly restored resulting in corruption on return.
+
+v2.14
+
+* Building in unit directories is no longer supported removing the issue of
+  leftover object files causing the top-level make build to fail.
+
+v2.10
+
+* Fix for windows register save overlap in gf_{3-6}vect_dot_prod_sse.asm. Only
+  affects windows versions of erasure code.  GP register saves/restore were
+  pushed to same stack area as XMM.
+
+3. CHANGE LOG & FEATURES ADDED 
+------------------------------
+
+v2.18
+
+* New 2-pass fully-dynamic deflate compression (level -1).  ISA-L fast deflate
+  now has two levels.  Level 0 (default) is the same as previous generations.
+  Setting to level 1 will switch to the fully-dynamic compression that will
+  typically reach higher compression ratios.
+
+* RAID AVX512 functions.
+
+v2.17
+
+* New fast decompression (inflate)
+
+* Compression improvements (deflate)
+  - Speed and compression ratio improvements.
+  - Fast custom Huffman code generation.
+  - New features:
+    * Run-time option of gzip crc calculation and headers/trailer.
+    * Choice of static header (BTYPE 01) blocks.
+    * LARGE_WINDOW, 32K history, now default.
+    * Stateless full flush mode.
+
+* CRC64
+  - Six new 64-bit polynomials supported. Normal and reflected versions of ECMA,
+    ISO and Jones polynomials.
+
+v2.16
+
+* Units added: crc, raid, igzip (deflate compression).
+
+v2.15
+
+* Erasure code updates. New AVX512 versions.
+
+* Nasm support.  ISA-L ported to build with nasm or yasm assembler.
+
+* Windows DLL support.  Windows builds DLL by default.
+
+v2.14
+
+* Autoconf and autotools build allows easier porting to additional systems.
+  Previous make system still available to embedded users with Makefile.unx.
+
+* Includes update for building on Mac OS X/darwin systems. Add --target=darwin
+  to ./configure step.
+
+v2.13
+
+* Erasure code improvments
+  - 32-bit port of optimized gf_vect_dot_prod() functions.  This makes
+    ec_encode_data() functions much faster on 32-bit processors.
+  - Avoton performance improvements.  Performance on Avoton for
+    gf_vect_dot_prod() and ec_encode_data() can improve by as much as 20%.
+
+v2.11
+
+* Incremental erasure code.  New functions added to erasure code to handle
+  single source update of code blocks.  The function ec_encode_data_update()
+  works with parameters similar to ec_encode_data() but are called incrementally
+  with each source block.  These versions are useful when source blocks are not
+  all available at once.
+
+v2.10
+
+* Erasure code updates
+  - New AVX and AVX2 support functions.
+  - Changes min len requirement on gf_vect_dot_prod() to 32 from 16.
+  - Tests include both source and parity recovery with ec_encode_data().
+  - New encoding examples with Vandermonde or Cauchy matrix.
+
+v2.8
+
+* First open release of erasure code unit that is part of ISA-L.
