HISTORY of the 7-Zip\r
--------------------\r
\r
+20.00 alpha 2020-02-06\r
+-------------------------\r
+- 7-Zip now supports new optional match finders for LZMA/LZMA2 compression: bt5 and hc5, \r
+ that can work faster than bt4 and hc4 match finders for the data with big redundancy.\r
+- The compression ratio was improved for Fast and Fastest compression levels with the \r
+ following default settings:\r
+ - Fastest level (-mx1) : hc5 match finder with 256 KB dictionary.\r
+ - Fast level (-mx3) : hc5 match finder with 4 MB dictionary.\r
+- Minor speed optimizations in multithreaded LZMA/LZMA2 compression for Normal/Maximum/Ultra \r
+ compression levels.\r
+- bzip2 decoding code was updated to support bzip2 archives, created by lbzip2 program.\r
+- Some bugs were fixed.\r
+- New localization: Turkmen.\r

+19.02 alpha 2019-09-05\r
+-------------------------\r
+- 7-Zip now can unpack files encoded with Base64 encoding (b64 filename extension).\r
+- 7-Zip now can use new x86/x64 hardware instructions for SHA-1 and SHA-256, supported\r
+ by AMD Ryzen and latest Intel CPUs: Ice Lake and Goldmont.\r
+ It increases\r
+ - the speed of SHA-1/SHA-256 hash value calculation, \r
+ - the speed of encryption/decryption in zip AES, \r
+ - the speed of key derivation for encryption/decryption in 7z/zip/rar archives.\r
+- The speed of zip AES encryption and 7z/zip/rar AES decryption was increased with \r
+ the following improvements:\r
+ - 7-Zip now can use new x86/x64 VAES (AVX Vector AES) instructions, supported by \r
+ Intel Ice Lake CPU. \r
+ - The existing code of x86/x64 AES-NI was improved also.\r
+- There is 2% speed optimization in 7-Zip benchmark's decompression.\r
