 HISTORY of the 7-Zip
 --------------------
 
+20.00 alpha    2020-02-06
+-------------------------
+- 7-Zip now supports new optional match finders for LZMA/LZMA2 compression: bt5 and hc5, 
+  that can work faster than bt4 and hc4 match finders for the data with big redundancy.
+- The compression ratio was improved for Fast and Fastest compression levels with the 
+  following default settings:
+   - Fastest level (-mx1) : hc5 match finder with 256 KB dictionary.
+   - Fast    level (-mx3) : hc5 match finder with 4 MB dictionary.
+- Minor speed optimizations in multithreaded LZMA/LZMA2 compression for Normal/Maximum/Ultra 
+  compression levels.
+- bzip2 decoding code was updated to support bzip2 archives, created by lbzip2 program.
+- Some bugs were fixed.
+- New localization: Turkmen.
+
+
+19.02 alpha    2019-09-05
+-------------------------
+- 7-Zip now can unpack files encoded with Base64 encoding (b64 filename extension).
+- 7-Zip now can use new x86/x64 hardware instructions for SHA-1 and SHA-256, supported
+  by AMD Ryzen and latest Intel CPUs: Ice Lake and Goldmont.
+  It increases
+    - the speed of SHA-1/SHA-256 hash value calculation, 
+    - the speed of encryption/decryption in zip AES, 
+    - the speed of key derivation for encryption/decryption in 7z/zip/rar archives.
+- The speed of zip AES encryption and 7z/zip/rar AES decryption was increased with 
+  the following improvements:
+   - 7-Zip now can use new x86/x64 VAES (AVX Vector AES) instructions, supported by 
+     Intel Ice Lake CPU. 
+   - The existing code of x86/x64 AES-NI was improved also.
+- There is 2% speed optimization in 7-Zip benchmark's decompression.
+- Some bugs were fixed.
+
+ 
+19.00          2019-02-21
+-------------------------
+- Encryption strength for 7z archives was increased:
+  the size of random initialization vector was increased from 64-bit to 128-bit,
+  and the pseudo-random number generator was improved.
+- Some bugs were fixed.
+
+
+18.06          2018-12-30
+-------------------------
+- The speed for LZMA/LZMA2 compressing was increased by 3-10%,
+  and there are minor changes in compression ratio.
+- Some bugs were fixed.
+- The bug in 7-Zip 18.02-18.05 was fixed: there was memory leak in xz decoder.
+- 7-Zip 18.02-18.05 used only one CPU thread for bz2 archive creation.
+  
+
 18.05          2018-04-30
 -------------------------
 - The speed for LZMA/LZMA2 compressing was increased
