- AES Crypt Plugin: Reduced max password length from 256 to 128 which improved performance by 22%
- RAR3-p (Compressed): Fix workaround in unrar library in AES constant table generation to enable multi-threading support
- CRC32: Prevent decompression of data used in CRC32 calculation on host. This leads to false negatives with TrueCrypt/VeraCrypt keyfiles
- RC4: Update -m 97x0 and -m 104x0 to new RC4 crypto library code, improving performance by 20% or more
- RC4: Updated hash-mode 7500, 9710, 9720, 10400 and 10410 to new RC4 crypto library code, improving performance by 20% or more
