9 | 1. KNOWN ISSUES |
| 10 | ---------------- | |
| 7c673cae FG |
11 | |
| 12 | * Perf tests do not run in Windows environment. | |
| 13 | ||
| 14 | * 32-bit lib is not supported in Windows. | |
| 15 | ||
| 7c673cae | 16 | 2. FIXED ISSUES |
| 224ce89b WB |
17 | --------------- |
| 18 | ||
| 19 | v2.18 | |
| 20 | ||
| 21 | * Mac OS X/darwin systems no longer require the --target=darwin config option. | |
| 22 | The autoconf canonical build should detect. | |
| 23 | ||
| 24 | v2.17 | |
| 25 | ||
| 26 | * Fix igzip using 32K window and a shared object | |
| 27 | ||
| 28 | * Fix igzip undefined instruction error on Nehalem. | |
| 29 | ||
| 30 | * Fixed issue in crc performance tests where OS optimizations turned cold cache | |
| 31 | tests into warm tests. | |
| 32 | ||
| 7c673cae FG |
33 | v2.15 |
| 34 | ||
| 35 | * Fix for windows register save in gf_6vect_mad_avx2.asm. Only affects windows | |
| 36 | versions of ec_encode_data_update() running with AVX2. A GP register was not | |
| 37 | properly restored resulting in corruption on return. | |
| 38 | ||
| 39 | v2.14 | |
| 40 | ||
| 41 | * Building in unit directories is no longer supported removing the issue of | |
| 42 | leftover object files causing the top-level make build to fail. | |
| 43 | ||
| 44 | v2.10 | |
| 45 | ||
| 46 | * Fix for windows register save overlap in gf_{3-6}vect_dot_prod_sse.asm. Only | |
| 47 | affects windows versions of erasure code. GP register saves/restore were | |
| 48 | pushed to same stack area as XMM. | |
| 49 | ||
| 7c673cae | 50 | 3. CHANGE LOG & FEATURES ADDED |
| 224ce89b WB |
51 | ------------------------------ |
| 52 | ||
| 53 | v2.18 | |
| 54 | ||
| 55 | * New 2-pass fully-dynamic deflate compression (level -1). ISA-L fast deflate | |
| 56 | now has two levels. Level 0 (default) is the same as previous generations. | |
| 57 | Setting to level 1 will switch to the fully-dynamic compression that will | |
| 58 | typically reach higher compression ratios. | |
| 59 | ||
| 60 | * RAID AVX512 functions. | |
| 61 | ||
| 62 | v2.17 | |
| 63 | ||
| 64 | * New fast decompression (inflate) | |
| 65 | ||
| 66 | * Compression improvements (deflate) | |
| 67 | - Speed and compression ratio improvements. | |
| 68 | - Fast custom Huffman code generation. | |
| 69 | - New features: | |
| 70 | * Run-time option of gzip crc calculation and headers/trailer. | |
| 71 | * Choice of static header (BTYPE 01) blocks. | |
| 72 | * LARGE_WINDOW, 32K history, now default. | |
| 73 | * Stateless full flush mode. | |
| 74 | ||
| 75 | * CRC64 | |
| 76 | - Six new 64-bit polynomials supported. Normal and reflected versions of ECMA, | |
| 77 | ISO and Jones polynomials. | |
| 78 | ||
| 7c673cae FG |
79 | v2.16 |
| 80 | ||
| 81 | * Units added: crc, raid, igzip (deflate compression). | |
| 82 | ||
| 83 | v2.15 | |
| 84 | ||
| 85 | * Erasure code updates. New AVX512 versions. | |
| 86 | ||
| 87 | * Nasm support. ISA-L ported to build with nasm or yasm assembler. | |
| 88 | ||
| 89 | * Windows DLL support. Windows builds DLL by default. | |
| 90 | ||
| 91 | v2.14 | |
| 92 | ||
| 93 | * Autoconf and autotools build allows easier porting to additional systems. | |
| 94 | Previous make system still available to embedded users with Makefile.unx. | |
| 95 | ||
| 96 | * Includes update for building on Mac OS X/darwin systems. Add --target=darwin | |
| 97 | to ./configure step. | |
| 98 | ||
| 99 | v2.13 | |
| 100 | ||
| 101 | * Erasure code improvments | |
| 102 | - 32-bit port of optimized gf_vect_dot_prod() functions. This makes | |
| 103 | ec_encode_data() functions much faster on 32-bit processors. | |
| 104 | - Avoton performance improvements. Performance on Avoton for | |
| 105 | gf_vect_dot_prod() and ec_encode_data() can improve by as much as 20%. | |
| 106 | ||
| 107 | v2.11 | |
| 108 | ||
| 109 | * Incremental erasure code. New functions added to erasure code to handle | |
| 110 | single source update of code blocks. The function ec_encode_data_update() | |
| 111 | works with parameters similar to ec_encode_data() but are called incrementally | |
| 112 | with each source block. These versions are useful when source blocks are not | |
| 113 | all available at once. | |
| 114 | ||
| 115 | v2.10 | |
| 116 | ||
| 117 | * Erasure code updates | |
| 118 | - New AVX and AVX2 support functions. | |
| 119 | - Changes min len requirement on gf_vect_dot_prod() to 32 from 16. | |
| 120 | - Tests include both source and parity recovery with ec_encode_data(). | |
| 121 | - New encoding examples with Vandermonde or Cauchy matrix. | |
| 122 | ||
| 123 | v2.8 | |
| 124 | ||
| 125 | * First open release of erasure code unit that is part of ISA-L. |
